It’s very easy to get a decent pair of headphones. For a few hundred bucks or less, you can score yourself a very classy pair of cans or in-ears that will be more than capable of presenting your music in a way that will make you rock out. But sometimes, you just need to cut loose. Sometimes, you just need to break the bank, go deep, and invest in something that will last you that years, and deliver the best sound you’ve ever heard. That’s what we're going to do, right here. Whether your budget is $5,000 or $500, we’re going to present the absolute pick of the best high-end cans available.
Before we get started, a couple of caveats. Firstly, no electrostatic headphones on this list. These require some fairly intensive equipment to run, and we felt like they could be in a roundup of their own. Secondly, we've combined over-ear and in-ear models, which mean that over-ears dominate. To us, that felt OK - it didn't feel like the experiences were different enough to warrant separate lists. Sound quality across the board is excellent, and there’s so little separating these headphone types that a lot will come down to personal choice.
Beyond that: we looked hard at value-for-money, the kind of sound offered, how each model compared to others, and how easy they were to drive (in other words, whether you needed an amp or not). Please feel free to disagree with us, by the way, by posting in the comments at the bottom.
What We Like: Ultimate sound.
What We Don’t: Ultimate price tag, “interesting” looks.
These are the best headphones on the planet. Nothing even comes close. You can argue as much as you like about the AUDEZE LCD-4s (below) and other high-priced models, but these are just better. In our full review, we said, "There’s only one conclusion here, and that’s that you should buy these immediately, if you can afford to. They are the single easiest Editor’s Choice award we’ve ever given out." You’d have to make one hell of an argument to knock this off the top spot.
There’s good reason for the enthusiasm, as the sound is incredibly open and rich. It also helps that they have a reasonably high sensitivity, meaning they can be driven by a variety of amps. Despite looks which could charitably be described as scifi, there’s absolutely no doubt in our minds that these are the best high-fidelity cans on the market right now. They offer better clarity than the LCD-4, better comfort than the Abyss Diana or the HiFiMAN HE1000, better overall sound quality than every single pair of cans on this list, and they have virtually no flaws to speak of. They are, for the foreseeable future, the best headphones available right now, and we will fight you if you disagree. Read our in-depth review.

What We Like: Extraordinary open sound.
What We Don’t: Quite heavy and bulky.
Any model in the AUDEZE catalogue (it’s pronounced Aud-e-zay, by the way) is going to be good. And we deliberated long and hard about which ones deserved to be in the upper echelon. You could definitely argue for including something like the LCD-X here, too, or the smaller LCD-2, but all things considered, and in the interests of not shoving out other great models, we’re going to call a winner for the LCD-4. If you get one AUDEZE headphone, make it this one.
It’s great not only because its massive 106mm drivers envelop you with a huge, powerful sound - particularly in the outrageous low-end - but because the comfortable earcups all but begged you to spend hours listening to them. At 200Ω, these are somewhat harder to drive, requiring a reasonably serious amp, but if you’ve got one handy then these will deliver you to absolute nirvana. They aren’t quite up there with the Utopia, but they do offer slightly deeper bass - and although we love the other planar models on this list, we think these are the absolute mustard in that particular category. Too expensive? Try a pair of LCD-2s, which offer almost-as-good sound at a slimmer pricetag.
See the AUDEZE LCD-4
What We Like: Fantastic audio quality, forward-thinking tech, just plain fun.
What We Don’t: Absolutely not portable, despite the welcoming impedance.
Looking for the model that offers the best value? Look no further. It’s actually staggering that these don’t cost four figures. While the sound quality they offer doesn’t really hit the LCD-4 or Utopia heights, they are among the best bang-for-buck cans anywhere. You get so, so much with these, and there’s so much to love about them, that they are easily top-three cans.
The NightHawk Carbons are cool. They are a pair of headphones that feel like they were designed by actual human beings, with the goal of making you really enjoy using them. They match mindbending science (biomimicry, anyone?) with excellent comfort, and a warm, balanced audio quality that we found absolutely addictive. They might look a little bizarre, and despite the low impedance we would very strongly advise against taking them on the road, but really: we absolutely adored these. The HD800s and Dianas of the world may offer better sound quality, but they don’t have the cachet, or the the stunning value. Oh, and the NightHawks come in a truly gorgeous leather carry-case, as a bonus. Read our in-depth review.
See the AudioQuest NightHawk Carbon
What We Like: Genuinely ups the ante on its predecessor.
What We Don’t: Sensitivity is a little low.
Abyss are a boutique headphone-maker that specialise in ultra high-end stuff. This is their flagship model, and it shares at least one thing with companies like Grado, in that it makes you look like a 1960s spaceman. The square design and all-black housing takes some getting used to, but from the moment you place these on your head, you’ll be in absolute audio nirvana.
It’s the new iteration of the AB-1266 Phi, on this list previously, and we adore it. It doesn’t have the clarity of the Utopia - or, arguably, the deep bass of the LCD4 - but it’s still stellar. They are thinner, lighter, more comfortable than their predecessor, making them an easy entry on this list. Be warned: the sensitivity is relatively low, so you’ll have to pick your amp carefully. You can read more about that in the Buying Advice section below. And fair warning: while these absolutely deserve a place at the top of this list, they can be hard to find on sellers like Amazon, at least for a reasonable price. It may be worth buying direct if you decide to take the plunge. If you do, we can absolutely guarantee that you’re in for one hell of a ride.
See the Abyss Diana
What We Like: Lightweight, comfy, excellent sound.
What We Don’t: A little difficult to power.
Although it will still benefit from a decent amp (and will absolutely sing with a really good one) thanks to its relatively low sensitivity, HiFiMAN's monster will deliver good sound no matter what, with a nanometers-thick planar driver that delivers accurate, highly impressive sound. There’s a very good reason why audiophiles love this particular pair of cans, and we think it’s a lock for this list for the foreseeable, easy.
We really like the design, too, including the grille-style open backs. It's comfy, lightweight, and capacious. Initially, we weren't sold on the pad material, but we came round. While this isn't going to beat the Focal Utopia or the LCD-4, it's a good high-end planar option that remains one of the best out there. By the way, HiFiMAN do offer a far more expensive pair of headphones, the Susvara (which we’ve also, confusingly, seen spelled Suvara by some retailers), but we think these offer better value-for-money. Nothing on the AudioQuest NightHawk Carbons, of course, but still.
See the HiFiMAN HE1000 V2
What We Like: Probably the best earbuds available.
What We Don’t: Unavailable specs.
Usually, we get a little bit antsy when we can’t find the specifications for individual models. In this case, we’re going to make an exception. Not only do Noble Audio make some of the finest audio gear on the planet, but the original Kaiser was an absolute beauty.
We don’t have many earbuds on this list (yes, we know they’re technically in-ear monitors, but that’s a pain in the backside to type, so how about you cut us some slack and save our aching fingers?) but these definitely qualify – not only for the wonderful sound with its immensely warm midrange, but for the fact that you can run these of conventional smartphone, no amp required. Oh, and each side has ten drivers. Ten! Overkill as a descriptive term doesn’t quite cut it. And if this doesn’t quite do it for you, the company has several models that we could have easily added to this list, including the legendary Katana and the significantly-more-affordable (and equally sweet looking) Savanna. Compared to the Andromeda below, these offer more refined sound, but you could easily go for those if you wanted to spend a little less and still get something good in your ears.
See the Noble Audio Kaiser Encore
What We Like: Stellar sound, distinctive color and design…
What We Don’t: Which may not be for everyone.
Slowly and surely, Campfire Audio’s range of in-ears has been winning fans across the world. It’s not hard to see why. With their distinctive astronomical naming scheme and their great color options (buying or modding the Andromeda in anything but green will see you shunned), they’ve become a fixture on the headphones circuit. Of course, that would mean nothing if the sound wasn’t up to par, and trust us: it very much is. This high-sensitivity in-ear is mint. Not quite as clean as the Kaiser above, but still excellent.
The company uses 3D printing, which is becoming a more common technique among headphone companies (like AudioQuest, who used it in their magnificent NightHawk Carbons) to shape the acoustic chamber in each housing, and the five drivers on each side are more than able to handle anything you can throw at them. Among in-ears, you’d have to look very hard to find better audio quality – only models like the Kaiser Encore, in our opinion, are better. Add to that the anecdotally great customer service, and the fact that the in-ears are made in small batches and each inspected by hand before they are shipped out, and you’ve got a real winner.
See the Campfire Audio Andromeda
What We Like: Outstanding, deeply human design.
What We Don’t: Treble could be better.
ZMF's Zach Mehrbach is a dedicated headphone modder-turned-manufacturer, and his Chicago company puts out arguably the most beautiful headphones on earth. The Eikon (the bigger brother of the Atticus) has some truly stellar design, with a signature ported housing that can be had in a variety of different woods, including cherry, padauk and camphor. It's the kind of thing that only Fostex (whose cans aren’t on this list) have really gotten right before, and if these headphones had even slightly better sound, they'd probably be near the top of this list.
That's not to say the sound is bad – just slightly lacking in the treble department, which we wish was a little more refined. All the same, what you're getting here is an absolutely gorgeous pair of headphones, delivered with a deeply human touch that we wish other manufacturers would replicate. Here's to whatever Mr Mehrbach does next.
See the ZMF Eikon
What We Like: A true classic, with sound to match.
What We Don’t: Geeky design.
There’s this idea – which we find ourselves continually referring back to – that a few years have to pass before something can be considered a classic. And despite the innumerable models that Sennheiser has released since 2009 – when the HD800 was released – this still holds a special place in our hearts. We could have put any high-impedance model from the company on this list, including the equally legendary HD600s, which we go into in a lot more detail below, but this is where our heart is at. You’ll never part us from our 800s.
The distinctive Sennheiser sound and the unique looks are still visible at audiophile conventions today, and it’s easy to see why this is considered an excellent baseline reference headphone for testing things like new amps. Even if you couldn’t be bothered with all that, this is a sound investment that will reward you for years to come. It’s one that has genuinely stood the test of time, and although the looks and design might turn some people off, the sound it is absolutely unimpeachable. O.G. status. If you want a Senn, and have the money, go for these: where the HD600s are the workhorse, these are the thoroughbreads.
See the Sennheiser HD800
What We Like: Grado’s legendary house sound.
What We Don’t: Not enough of a jump from the PS1000E - and it’s far too expensive right now.
One of the biggest problems we had with the PS1000E, which featured on this list previously, with its comfort. Grado cans have never been comfortable, but the PS1000E was often genuinely difficult to wear. It’s hugely encouraging, therefore, to see that the company’s newest model, the PS2000E, makes a real effort to fix this. The pads are soft and squashy, and the leather headband feels fantastic. And in terms of sound, when Grado say this is the best pair of headphones they have ever made, they weren’t kidding. The open-back design and the Brooklyn company’s absolutely legendary signature sound is one hell of a combo.
But: we are not sure that it justified $1,000 price boost. Yes, we like the comfort, and yes, the sound magnificent… but we would struggle to recommend these over something like the AUDEZE LCD-2s, or a second-hand pair of LCD4s. Unless you are a serious devotee of the Grado sound, there are other headphones you could get that justify the pricetag a little bit more. While they absolutely deserve to be on this list, and are a worthy replacement for the PS1000E, we expected a little bit more bang for our buck here.
See the Grado PS2000E
What We Like: Indie cred - and you’d hardly realise they’re closed-back.
What We Don’t: Sometimes hard to find.
Few headphone manufacturers have been as energetic or as focused as Mr Speakers. Their Ether C was on this list previously, and since we last updated, they put out a truly extraordinary closed-back model that we think does everything the Ether C does, at a far more attractive price.
Not only is it more striking than the Ether C, with its distinct teardrop shape, but it’s also one of the few closed-back planar headphones available (the OPPO PM-3 being the other) that makes it onto this list. One listen should make the reason why obvious. These sound absolutely terrific, driven by a patented driver design, which they call V Planar, and which uses a pleated surface to move more effectively. The result? Tight bass, clear tone, and superb balance. While it may often be a little difficult to track these down – you’ll either have to rely on dodgy-looking Amazon listings, go through the company direct, or hope that your local hifi store stocks them – they are absolutely worth tracking down. And to be clear: we vastly prefer these over the PM-3, which despite also being a closed-back planar, doesn’t offer quite the quality levels.
See the Mr Speakers ÆON Flow
What We Like: Clear and neutral sound, superlative comfort levels.
What We Don’t: A little dull, perhaps?
If this list were about comfort alone, then the Amiron Home headphones would be at the very top. They offer absolutely extraordinary comfort, thanks to the microvelour pads and band, and although they are not particularly light in weight, they feel virtually weightless when they are on your head. We go so far as to call these the most comfortable headphones ever made – or at least, in the top three of all time. You’d get them if you value this particular aspect over all others. Compare these to the Sennheiser HD800s - the Senns offer better sound, but can’t touch the Beyers for comfort levels.
And although the color scheme, styling and accessories are a little dull, the sound does match the construction. It’s clear, sweet and neutral, adhering to the Beyerdynamic house sound, presenting the material in the best possible light without ever giving undue coloration. If you like your music precise and clean, then these will make you very happy indeed. We think they are at a reasonable price, too – there are plenty of far more expensive headphones that we think don’t justify their pricetag. With the Beyers, you know exactly what you’re getting for your money. Although to this day, we’re still not sure what Amiron means… Read our in-depth review.
See the Beyerdynamic Amiron Home
What We Like: Sound that’s stood the test of time.
What We Don’t: Bit of an old warhorse! And you need a decent amp to drive them.
You may very reasonably ask why we're putting a pair of headphones that is almost twenty years old on this list. We wouldn’t do so if we didn’t have a damn good reason, and that reason is simply that these headphones are as good today as they were when they were released. Other models have been replaced or superseded with new technology and better driver tuning, but this is like the Illmatic of headphones. It’s lightning in a bottle, and it hasn’t been bettered since. Even today, this is a firm favorite among audiophiles, and we’d be crazy not to include it here.
While they’re not going to beat the precision or depth of the bigger models, the HD600s still go toe to toe with headphones that cost twice as much, like the Bowers and Wilkins P9, below. They are renowned for being able to respond well to a huge range of amplifiers – which you will definitely need one of, due to their high impedance – and for their ability to accurately translate sound. They are far from the most current model, and you should expect their construction to be a little barebones and unsophisticated, but match these with a Schiit stack, or something like it, and you’ll be witness to one of the great pairings in audio. By the way, you may be asking why we chose these instead of the HD650s, or the 598s, both of which are a little newer. The answer? The HD600s sound better. Sometimes it is just that simple.
See the Sennheiser HD600
What We Like: Styling, solid audio quality, B&W's legendary quality.
What We Don’t: Doesn’t really advance the sound from the P7.
When it comes to offering luxurious kit, Bowers & Wilkins have no equal. Their P5 and P7 cans were, for a time, the absolute last word in design quality, with sweeping metal accents and soft leather. The P9 takes things a step further. With Italian Saffiano leather and aluminum arms, it recalls high-end sports cars in its design - and at a relatively OK price, too.
We debated whether or not to include both this model and the wireless P7 on here. We reviewed the P7 a little while ago, and we love that enough to include it on our list of the best Wireless headphones of this year. In the end, obviously, we decided to stick with the gorgeous P9. It might not take the sound a huge way beyond that of the P7, but it looks and feels great, with closed-back housing and comfortable earcups. It’s also quite comfortable in just about any listening situation, from a decent amp to smartphone use on the go. Far from the best pair on this list - it just doesn’t have the audio quality of models like the HD800 or even 600 - but still a winner.
See the Bowers & Wilkins P9
What We Like: Probably the most gorgeous mid-range cans ever made.
What We Don’t: Dodgy in-line microphone.
The AUDEZE and B&W cans may offer technically-more-accomplished sound, but none of them are quite as beautiful as the 99 Classics. Romanian maestro Antonio Meze has built a truly spectacular pair here, which are among the most beautiful audio objects we’ve ever seen. We regularly use our pair for pleasure listening, outside of work - and when we, who live and breathe headphones and amps, use a piece of gear in our downtime, you know it’s going to be good.
The detail, fit, and finish are extraordinary, and the wooden earcups are an absolute pleasure. The sound is balanced, precise, and elegant, and although it’s not going to trouble the LCD-4s, it’s still a stupendous pair of cans for the amount of money they’re asking. We had a great time with these when we reviewed them, so much so that it genuinely pains us to put them this low on the list. Please don’t mistake that as an indication that they are bad. On the contrary, they are genuinely special, if not quite as elite as some of the others. Read our in-depth review.
See the MEZE 99 Classics
What We Like: Extraordinary sound, perfect fit.
What We Don’t: ALL THE TANGLES.
While you’ll spend a lot of time untangling the ultra-thin cords of these earbuds, the result is well worth it. We’re big fans of the Australian company Audiofly and with the AF1120, we think they’ve got a real winner. They don’t quite hit the heights of the Noble or Campfire models, but in the sub-$1000 range, these are probably the best in-ears available. They have some terrific audio quality, with a highly tuned crossover that creates some outstanding realism and space. They’ll sound just fine driven from a smart phone, but we’d recommend a good amplifier to really heighten the experience.
Although these are technically designed for stage musicians, they work perfectly well in a variety of situations, including, as we say, smartphone use. Excellent isolation and that wonderful, block-rocking sound means these are arguably the finest mid-range buds around right now. Just come with some Zen exercises for when the tangles happen. Read our in-depth review.
See the Audiofly AF1120
17. OPPO PM-3 ($399)
What We Like: Good value-for-money, offers planar sound at a budget price.
What We Don’t: Nothing hugely special.
Yes, we are aware that OPPO’s PM-3s have legions of devoted fans – ones who won’t be all that thrilled to see them this low on the list. But while we do think these are a great pair of headphones, we don’t think they offer enough to really bump them higher. It’s true that they offer solid planar magnetic sound at a very good price, and when paired with a good amp, they can be genuinely spectacular, but we just don’t think they really bump the needle.
That being said: despite the fact that their main business is Blu-ray players, OPPO do know how to make a pair of headphones. No argument there. The audio quality they offer is airy and bright, with the characteristic depth and soundstage that planar magnetic drivers offer. They are built well, and although the styling is a bit dull, they will definitely last for a while. Their only real competitor, in terms of planar sound at a budget price, is the Monoprice M1060 - which has build issues that mean we’d struggle to justify its presence here – and we think these are absolutely the superior headphones. Buy these if you want planar sound, but you don’t want to shell out huge amounts for the LCD-4 or LCD-2.
See the OPPO PM-3
And When You Never Want To Buy Another Pair Ever Again:
At this point, we should probably reiterate why the Sennheiser Orpheus and the HiFiMAN Shangri-La aren’t on this list. For starters, they are electrostatic, and we’ve already talked about why we declined to include those on this particular list. Secondly, they are more dedicated headphone-amp combos then straight headphones. Thirdly, there are already plenty of ridiculously expensive headphones available but we could put in this slot. Like the one below. Go on. Fight us.
What We Like: God-like sound.
What We Don’t: Gold-like finish.
It’s not just the name that leads us to call the Final Audio Design SONOROUS X last pair of cans you’ll ever need. It’s the fact that the Japanese–made cans offer some of the best sound on the planet. If you can get past the millionaire-friendly gold finish, what you end up with is an incredibly accurate pair that will take whatever you throw at it and rocket it into the stratosphere. The construction is impeccable, and we can’t imagine needing to pick up another pair of cans after you buy these. There are more expensive cans out there, but very few that offer this much satisfaction.
By the way, if you do decide to spring for these, don’t be put off by the two one-star reviews they have on Amazon – the only reviews on the product. “I'd recommend buying beats instead they are personally better my opinion,” says Isaiah Byre. “They should last at least 50 years and still have a bigger bass than the bombings on Syria. #MakeAmericaGreatAgain #TrumpTrain”, says an anonymous reviewer. We don’t really know how to respond to those. Beyond doing a Tommen Baratheon and walking out a top floor window.

If you’re about to invest in a pair of high-end headphones, then it might be worth knowing the key pros and cons for each of the three main types. If you already know your headphones, you can probably skip this section.
These classifications essentially describe the construction of the headphone. Over-ears fully enclose the ear; on-ears sit on top of it, leaving the side exposed; and in-ears are much smaller units that slot directly into the ear canal.
They all have their own advantages and disadvantages. Over-ears typically provide larger drivers and better sound quality, but can be heavy and bulky, and aren’t really suitable if you’re claustrophobic. On-ears compromise a little on the sound quality (and you won’t find any on the list above, although you will in our list of the best wireless headphones) but tend to be lighter and more portable. Finally, in-ears are the lightest of all, but can be an acquired taste due to the fact that they are often uncomfortable to use for long periods. They don’t, however, compromise on sound quality.
The more committed to audio quality you are, the more likely you are to go for a big pair of over-ears that you can listen to in one place (preferably with a good amp). Portability means you’d be going for a pair of in-ears or on-ears. Really, it’s down to what you find comfortable, so if you can, try and audition a few types before you buy.
By the way, there’s a myth that over-ears are intrinsically superior to on-ear or earbuds. Wrong. Plenty of those models offer superb sound quality, and there are plenty of reasons to choose them. If you wear glasses, for example, you might find that over-ears are uncomfortable to wear for long periods of time. In this case, on-ears may be a better option.
The idea of closed-back and open-back headphones can be confusing, until you know what to look for. It's something that can make a major difference in sound quality, so it's worth knowing about.
The term refers to the outer part of each can. Closed-backs (sometimes referred to as sealed headphones) are completely closed off, with the inner workings of the headphones hidden away. Open-backs, on the other hand, leave it exposed, usually protected behind a rigid mesh grille.
As we said, this has to do with sound. Open-backs sound better, as they allow air to pass through, and interact with the audio produced by the drivers. This makes the headphones sound more open, natural, and much, much larger. They also have the benefit of looking extremely cool. Closed-backs are the opposite, with the drivers and electronics hidden away, and they don’t sound nearly as good.
So why not go for open-backs as a matter of principle? Easy: bleed. When applied to cans, this word refers to how much sound leaks out when music is playing, and open-backs leak a lot. Even at low volumes, anyone around you will be able to clearly hear what you're listening to, and they probably won't appreciate the enhanced audio quality. If you do the bulk of your music listening alone, then by all means, go for this. But if you plan on using your cans in company, then go for a pair of closed-back ones.
We put a lot of emphasis on impedance here at TMS – and with good reason. In terms of headphones, it’s probably the single most important spec there is. It can tell you how much power you need to drive a headphone, and how accurate that headphone’s sound is likely to be.
Impedance refers to the electrical resistance of the headphones. It’s not just about how much voltage and current they can take, but how much they need to operate properly. We could get deeply technical here, but the upshot is this: the higher the impedance, the more power you will need to drive the cans.
Any pair with an impedance of less than 32 ohms (Ω) can be taken to an acceptable level without an amp. 32-100 ohms is a little bit of a grey area – you’ll probably be able to run cans in this range off mobile devices, but the result won’t be quite as good. Over 100 ohms? Yeah, you’re going to need a separate amp. These are just not going to work off your smartphone.
(Low impedance isn’t bad, by the way - far from it. The Audiofly AF1120s, an impeccable pair of buds, have a very low impedance of around 18 ohms, meaning they can be driven off a phone, or even a small audio player.)
You might also reasonably ask why you would go for a high impedance anyway? If everything else is equal, why settle yourself with extra power requirements? Because higher impedance means the headphones are more able to accurately reproduce the sound without artefacts. Usually, a pair of headphones with a high impedance figure means that you’re in for a fun time.
If impedance is the most important thing to know about a pair of headphones, then sensitivity comes a close second. It's not absolutely essential to know it, but it can give you an idea of just how loud the headphones are likely to be.
It’s a measure of how efficiently the drivers in the cans make sound – or, more prosaically, how loud they will get from a constant source of one milliwatt. The higher the sensitivity (which is measured in decibels, or dB), the more likely the cans will be to respond to a larger variety of players or amps. Ones with lower sensitivity need slightly more power, but you can drive them at higher volumes for longer, whereas those with high sensitivity prefer more moderate volumes.
Example: most of the headphones on this list have a sensitivity above 95dB. But the Abyss Diana hovers at around 91dB – and its predecessor, the AB-1266 Phi, was even lower, at around 86dB. That means that at the same amount of power, the Diana won’t be quite as loud as other models. Again, this isn't necessarily a huge problem, especially with headphones, but it’s worth bearing in mind.
By the way, we’ve only touched on topics like impedance and sensitivity here. We go into a lot more depth, with many more practical examples (and a nifty explainer video!) In our full explainer of headphone specs.
When you're looking at the models in the list above, you're going to see a few terms continually popping up. Among the most common are things like dynamic driver, magnetic planar, and electrostatic. While understanding these is a little less important than understanding things like impedance and sensitivity, they’re still worth breaking down. They refer to the method a pair of headphones uses for getting sound to your ears, and we’re going to lay out the three main ones as simply as possible.
Dynamic drivers are by far the most common – the kind of thing you'd find in most cans you can buy at the store. In these, sound is transmitted by a moving coil of very thin wire which reacts with a magnet, moving the speaker diaphragm and producing sound. It's a relatively inexpensive method, and in terms of sound quality, it's by far the least desirable. This does not – repeat, not – mean it is bad. The Focal Utopia, at number one with a bullet on our list, are dynamic driver headphones, and they wipe the floor with just about everything else. But when compared with the other two types below, it's probably the most everyday.
Magnetic planar (sometimes planar magnetic) cans are renowned for the delicacy of their sound. The HiFiMAN, AUDEZE and OPPO models above, among others, use it. Instead of using a coil of wire, these models spread the magnetic force across the diaphragm. This requires stronger magnets, but produces infinitely better sound. You're also probably going to need a more powerful amplifier to get these working as they should be. They are usually, but not always, more expensive than standard dynamic driver headphones.
Electrostatic models are in a whole class of their own – and we elected to steer clear of them here, as they’re overkill for just about everybody. They use an electrically-charged diaphragm, made of mylar, sitting between two conductive plates – one charged negatively, the other positively. The movement of the diaphragm produces the sound. Electrostatic cans are unwieldy, expensive, and hard to use, requiring specialised amps – even if they sound utterly glorious. We might not have featured them here, if you're interested, manufacturers like Stax are still dominating the field.
You do also get balanced armutares. These are unique to in-ears, and often contain multiple drivers, consisting of coils, suspended between magnets and wrapped around metal armatures.
Drivers are the part of the cans that produce sound.
You have two of them, obviously, one left and one right. Think of the drivers as tiny little motors that convert the audio signal into something you can actually hear, using a combination of diaphragms, magnets and coils to vibrate, and produce sound.
Drivers are measured in millimetres (we’re not entirely sure why, when so many other sound equipment measurements are in inches). The actual figure we give is a little misleading - it’s arrived at by using a very complicated mathematical formula that takes into account the overall surface area of the driver, and at this point, we’re just going to tell you that a 50mm driver is bigger than a 40mm driver.
As a general rule, the larger the driver, the more powerful the sound. That being said: it doesn’t necessarily mean better sound. Not always. It’s far more important to note what the driver is made out of, which will have are far more dramatic effect than a few extra millimetres. These materials may include things like aluminum or beryllium, each of which have their own distinct sonic characteristics. Don’t, in other words, be fooled with the manufacturer trumpets a huge driver size. In practical terms, it may mean very little.
Not always - but it sure helps.
An amplifier - and you can get dedicated amplifiers that will do exactly the job you need, including portable ones - offloads the task of increasing the power of the audio to a separate box. Whether you go for a desktop one or a portable one, they can vastly change your audio experience. Any headphones with an impedance of over 100Ω are almost certainly going to need a separate amp. And even if the impedance is much less, virtually any pair of headphones will sound stratospherically better when you plug them into one.
But how do you match them? What amp do you go for?
It is so, so easy to get very deep into the science here, but really, there’s a much simpler method. Simply make sure that the output impedance of the amp is 1/8th or less of the headphone impedance. Follow that, and you’ll get absolutely perfect audio quality for that particular pair of counts.
For example, let’s say you splash out and buy the Final Audio Design SONOROUS X, because you won the lottery or something. Those have an impedance of 16Ω. That means your amp needs an output impedance of no more than 2Ω, which is very achievable for most models.
When you’re picking an amp, we recommend spending at least around the same as what your cans cost. Also: check if the manufacturer of the headphones makes an amp, which will almost always be matched perfectly with their companion cans. Ultimately, they’re built for each other - and it’ll be reflected in the sound quality.
If you want a full guide to getting the best out of your headphones, you're in luck. We've got one right here on this site.
Not there, obviously. Here's why.
Short version: it's useless when picking audio gear.
Think of the entire range of sounds you can hear, from a very low bass drum to the high, musical sound of a finger running around the rim of a wet wineglass. Each of these sounds occupies a specific frequency, a particular place in the spectrum of sounds, which we can measure using a value known as Hertz, or Hz.
It sounds tricky, but it isn’t. That low bass drum will have a low hertz measurement (Between 20-100Hz) while the wineglass noise will have a much higher one (around 17,000Hz). The human voice appears around 85-255Hz. You'll notice that these are approximate measurements, and this is because any sound will actually have a number of different frequencies, all mixed together. As a general rule, if you know something in Hz, you can work out how low or high it is.
(Quick aside that’s quite important: a thousand Hertz is also known as a kilohertz, or kHz, so if you see something like 20kHz, all it means is twenty thousand Hertz.)
Headphones, and almost all other audio equipment, have what is known as a frequency range. This shows the highest and lowest sounds they can produce. So if a pair has a frequency response of 20Hz to 20kHz, it can comfortably produce any sound between those two values, meaning your bass drum and wineglass are A-OK.
Most models have ratings around this area. Some go really over the top, boasting that they can reach up to things like 40kHz or even 50kHz. Since the range of human hearing only goes up to 20kHz, we’re the first to admit that this seems a bit weird. Really, it's a marketing gimmick; the manufacturers build models that certainly can go up this high, but you'll never get a chance to test it out by virtue of the fact that you'll never actually be able to hear it, even if you’re a teenager.
That’s why we’d argue that frequency ranges are completely useless when you’re deciding what to buy. There are people on this planet who can tell the difference between 5Hz and 6Hz, but we’re pretty sure one is dead, and the other two are in insane asylums. It’s not about how wide your cans can go: it’s about what they do with the spectrum in between.
Headphones have one simple goal – and it’s the same whether they are a pair of $4,000 monsters or a tinny set of iPhone earbuds. It's to block out the world around you, and pipe music into your ears. The more they do this, the better your experience will be.
This aspect is known as isolation, and it’s a measure of how effective a pair of headphones will be creating a seal around or in your ears. The tighter the seal, the less likely you are to be bothered by outside noise.
We use the word measure with caution. To our knowledge, there is no actual industry standard measurement for how much sound a pair of headphones blocks out, which is probably due to the large amount of human head and ear sizes in our species. It is, after all, quite difficult to get a standard human head! However, we can offer some general principles to help you judge how good a pair of headphones isolate your ears.
Generally speaking, in-ear headphones have the best isolation properties, as they quite literally block the entire ear canal. Over-ear headphones our good, too, because they seal the entire ear off from the outside world - although if the headphones are open-back, you they may allow sounds from outside to penetrate. On-ear headphones are generally considered to have the worst isolation, because of the way they sit on the ear, which allows sound in.
The softer the material of a pair of ear cups, the more likely it is to create a decent seal against your skull. Large cups will usually create a better seal the small ones. But again: everyone has a differently-shaped skull, and different-sized ears. And remember: isolation works both ways. Headphones that isolate effectively will mean that your co-workers won’t know you are listening to Justin Bieber. You’ve been warned.
Not as simple a question to answer as you might think.
On the surface of it, you appear to always get more for a high pricetag. Better quality sound, better construction, luxurious accessories…start moving into the four-figure range, and this is what you can expect to see. As a general rule, it is true that higher prices will give you better experiences. But – and it’s a big but – this isn’t always the case, and the trick is to be able to spot value-for-money, and when a pair of headphones is punching out of its weight class.
To illustrate this, we offer two examples.
The first is the AudioQuest NightHawk Carbon. It costs around $700, not even within sniffing distance of some of the prices of the other models in our list…and yet we ranked it at number three. The reason for this is that it offers overall value that is far in excess of some of the models below it. While it may not beat them in individual aspects like sound quality, it offers such a brilliant experience at such a good price that we think deserves to be in the upper echelon
Second example: the Grado PS2000E. It costs almost $2,000 more than the Carbons, but the latter is the one we’d go for. Why? Because as we said in the list above, we don’t feel that the PS2000Es do enough to justify their high price tag. They are great cans, they belong in this list…but they just don’t do enough to push them into the upper reaches, or to beat out the ones above them. This is a case where spending more money won’t guarantee you a better experience.
As always, we recommend choosing a pair of headphones that is right for you, rather than simply going for the most expensive pair you can afford. Check our in-depth reviews to find detailed thoughts on the models here, as well as plenty of others.
