Portable, Closed Headphones Mega-Review

I may have gone a little overboard.

Last updated on February 18, 2015 to increase the rank of the B&O H6 after longer-term use of the top few headphones.

The mass-market headphone business has changed dramatically in recent years from two huge influences:

For years, geeks like me would recommend that most people get inexpensive studio-monitor headphones like the 280 Pro, ATH-M50, and MDR-7506 for listening at their computer desks. These offer good isolation, reasonable sound, and long-term comfort for around $100, but aren’t practical for portable use: they’re large and don’t fold much, and they usually have long, coiled cables that are unwieldy at best when away from a desk. Fortunately, the $200-and-up portable category has boomed in the last few years with amazing improvements in comfort and sound quality, dramatically outclassing the old studio monitors. Those were great recommendations for years and are still excellent values, but they’re no longer a good default recommendation.

My criteria for this review is what someone seeking good headphones today probably wants:

The hard price cap is $400, but ideally, these should be under $300.

Headphones not included


I’ve bought or been loaned almost all of the headphones in this review and spent significant time with them at home, except the B&W P7 and Beats Pro. I tried those in an Apple store by plugging each into my iPhone, playing the same test tracks that I used at home, spending at least 10 minutes on each one taking notes and sketching an estimated response curve, and comparing them back-to-back to the nearby models and my AKG K545 that I wore into the store.

I tested each headphone with my iPhone by itself as the source first, then with a larger desk setup: three headphone amps (Asgard 2, UCA202, Icon-2) simultaneously connected to a Gungnir DAC. I didn’t detect any noticeable differences between amps and DACs for the headphones in this review, but they provided an easy way to plug in 3 headphones at a time to compare them back-to-back.3

I listened to what you probably think is terrible music, but it’s well-recorded, it spans a wide range of tones and recording types, and I know the details extremely well.

I then had my wife listen to the same headphones without telling her my thoughts, and she came to almost all of the same conclusions, so I know that either I’m not nuts or both of us are.

Without further ado, here are my rankings, followed by condensed reviews of each model:

Sound quality ranking

Many people prefer a warm, “laid-back” tone that lacks some midrange presence, most upper treble response, and the fine detail that good treble response brings. This avoids the harshness that unrefined midrange and treble can bring on inexpensive headphones, so the sound is less fatiguing after long periods. But it’s like adding milk to coffee: the lost vocal strength and treble detail also make good recordings more dull and forgettable.

The other end of the preference spectrum is detail, clarity, and an “airy” feel that great treble can bring, and more energy in vocals that a strong midrange can bring. Great treble is my preferred style, and it’s what makes people say, “Wow! That’s so clear!” The downside is that it’s hard to get that right without sounding harsh or tinny.

If you prefer a laid-back tone, you should probably get the NAD VISO HP50 or PSB M4U 1, as they’re the best-sounding examples of that tone. If you like treble detail, you should probably get the AKG K545 or K551.

From best to worst, with that qualification in mind:

  1. B&O H6: Light bass, nice though inconsistent midrange, and excellent treble and clarity. An excellent tone for treble fans. Almost needs an amp, though — bass becomes noticeably weaker at high volumes without one.
  2. AKG K551: Lighter bass, slightly recessed midrange, otherwise excellent: a treble-rich, clear, highly detailed sound without sounding harsh, although music that depends on strong bass can sound thin. Almost sounds like midrange open headphones, which I didn’t think was possible in an inexpensive closed headphone.
  3. AKG K545: Very similar to the K551, but with occasional slight harshness in upper-midrange and a bit less treble finesse.
  4. NAD VISO HP50: Slightly boomy bass, smooth midrange, somewhat weak treble, and mediocre detail. It’s the best implementation of a smooth, “laid-back” tone I’ve heard, providing the easy-listening aspects without losing as much detail as most others attempting it. It’s a very agreeable sound, as if it were designed by committee: it won’t offend anyone, but you won’t have any “Wow!” moments.
  5. PSB M4U 1: Nearly identical to HP50, but less midrange refinement and slightly boomier, muddier bass, with the same weak treble and mediocre detail. Still a very good “laid-back” tone, but the HP50 is slightly better.
  6. Master & Dynamic MH40: A laid-back tone with bass that’s strong but just below overpowering. Great detail and finesse despite having the rolled-off treble and weak detail typical of laid-back tones, with mostly great midrange presence and smoothness, although there’s a withdrawn portion of the upper midrange.
  7. Focal Spirit One S: Slightly boomy and muddy bass, and a muffled upper treble that limits the detail. Great midrange presence and smoothness. Overall a good, but not great, sound.
  8. B&W P7: Slightly boomy bass, slightly harsh midrange, and lacking in treble and detail. A laid-back tone, but not done as well as the HP50 and M4U 1.
  9. KEF M500: A very balanced tone. Nice medium-strength bass, but slightly muddy. Great midrange presence with only a hint of harshness. Lower treble is nice, but upper-treble crispness is muffled. Overall, extremely good sound for an on-ear — easily the best on-ear I’ve heard.
  10. Sony MDR-7506: Good sound considering its price, with an unusually even tone and proper midrange presence, although it has a slightly telephone-like midrange harshness and lacks the smoothness and detail of higher-end models. Does not qualify for the review — this is an inexpensive studio-monitor headphone, with a long, coiled cable and no remote, included for reference.
  11. Beats Studio: Slightly too strong mid-bass, otherwise surprisingly good tone and detail. But the ANC circuit produces a constant, annoying, low-level hiss, the ANC cannot be turned off, and the headphone doesn’t work passively. Worse, it’s not even good ANC, making no audible difference from passive isolation in my test. A passive version without ANC would have jumped a few spots up and would likely be a great value.
  12. V-Moda XS: Too much bass and weak treble — good for an on-ear, but doesn’t compete with over-ears.
  13. B&W P5: Slightly boomy bass, recessed mids, very dull treble, weak detail — OK for an on-ear, but doesn’t compete with over-ears.
  14. Sennheiser Momentum (Over-Ear): Too much bass, a bit boomy, and a huge lack of treble and detail. An attempt at the laid-back sound that’s dramatically inferior to the HP50 and M4U 1.
  15. Sennheiser HD 380 Pro: Slightly harsh midrange, and noticeably lacking the treble response and detail of more modern drivers. Does not qualify for the review — this is an inexpensive studio-monitor headphone, with a long, coiled cable and no remote, included for reference. The 280 Pro tested slightly worse.
  16. Blue Mo-Fi: Good bass and midrange, but extremely lacking treble and detail so much that it sounds muffled and incomplete. Another attempt at the laid-back tone that’s dramatically outclassed by the HP50 and M4U 1, with even less detail than the Momentum. I found the built-in amp (!) to make no audible difference in quality — only volume.
  17. Bose QC25: Unlike most active noise-cancelling (ANC) headphones, the QC25 can operate passively. With ANC off, an old-Beats-like bass boominess dominates, the midrange is very recessed, and treble detail is severely lacking, as if you’re listening through a pillow. When the ANC is turned on, an equalizer is also engaged that dramatically boosts the midrange and treble, but it goes too far and sounds very harsh and artificial. The ANC is excellent, though.
  18. Beyerdynamic T51i: Pretty much all bass, with none of the treble detail Beyerdynamic is known for. It’s just an on-ear, but it’s poor even among other on-ears.
  19. Apple EarPods: No bass, harsh mids, no upper treble, no detail. Included for reference.
  20. Beats Pro: Extremely boomy, imprecise bass so overpowering that you can barely hear the extremely recessed midrange or the pretty decent treble detail.
  21. Sony MDR-1R: Sloppy yet weak bass, harsh telephone-like midrange, severe lack of treble and detail that sounds extremely muffled. This is the worst sound I’ve ever heard from a headphone over $50 that wasn’t obviously defective.

Comfort ranking

From best to worst:

  1. AKG K551: Extremely comfortable, with featherlight pressure spread across very wide earpads. One caveat: those wide earpads get sweaty sooner than most headphones because they’re covering much more area.
  2. Sony MDR-1R: Excellent comfort, due mostly to its extremely light weight and very soft earpads.
  3. B&O H6: Very light with excellent pads.
  4. PSB M4U 1: Moderate size and weight, but they’re handled well by excellent earpads.
  5. Sony MDR-7506: Light weight, decent pads, and light clamping force make this a very comfortable headphones, although the pads are a bit small.
  6. AKG K545: Light weight, but the pads could be slightly bigger and softer. Halfway between the K545 and K551 pads would be an ideal comfort/sweat balance.
  7. Bose QC25: Bose’s usual light weight and soft pads, but with slightly more clamping force. The pad rims could also be slightly wider to spread the pressure across a wider area.
  8. KEF M500: The on-ear design is a big comfort disadvantage, but this is the most comfortable on-ear I’ve found. It’s extremely lightweight despite its metal construction. The flat-faced leather pads are comfortable, although they could use more padding since they collapse to the hard plastic underneath too easily. Clamping force was a bit tight at first but was easily loosened by a bit of gentle headband stretching.
  9. Master & Dynamic MH40: Overall good comfort, but not excellent. They’re slightly too heavy for their size, which is fatiguing after a while, and some people may find the earpads slightly too small.
  10. NAD VISO HP50: Similar to M4U 1, but with noticeably more clamping force, slightly harder pads, and a worse headband.
  11. B&W P7: Not bad, but a bit too heavy and tight.
  12. Sennheiser HD 380 Pro: Tight fit with far too much clamping force.
  13. Focal Spirit One S: The earcups are too small, still pressing on the edges of my ears. Clamping is a bit tight as well, and the top headband pad is very small and narrow.
  14. Beats Studio: Too tight, and the earcups are too small.
  15. B&W P5: On-ear design limits longevity, a bit heavier than most on-ears, and there’s a strong “suction cup” effect on my ears.
  16. V-Moda XS: On-ear design but very heavy, with weight concentrated on thin pad rims.
  17. Blue Mo-Fi: Very tight clamping force, mostly because these are very heavy at 482g — almost as heavy as orthodynamics,4 but without the weight-spreading designs that Audeze and HiFiMAN have figured out to make theirs moderately comfortable. Substantial force is also concentrated on the top-center pad on the headband. The complicated headband is highly adjustable, including a clamping-force knob, but I couldn’t find any settings that were comfortable.
  18. Beats Pro: Tight and small earcups like Beats Studio, but much heavier at 400g.
  19. Beyerdynamic T51i: On-ear design, but extremely heavy and tight. Again, nothing like Beyerdynamic’s bigger headphones.
  20. Apple EarPods: Maybe it’s just my ears? But it should mean a lot that these aren’t actually the worst…
  21. Sennheiser Momentum (Over-Ear): Much too tight, with earcups that are far too small for over-ears. The cups also apply uneven pressure, almost digging into my head at some points. A profoundly uncomfortable headphone — these feel even worse than the MDR-1R sounds.

Portability and fashion ranking

Portability includes size, foldability, quality of remote clicker controls, and general fashionability.

Ideally, the headphones should be reasonably small on the head, able to comfortably drop to the neck for brief periods, and fold easily into a small bag. The remote-control clicker should have the 3 standard iPhone buttons easily distinguished by feel, and the buttons should be easy to press, with enough tactile feedback that double- and triple-press commands should be easy to perform without frequent errors. The cable should be replaceable, not permanently mounted. And you shouldn’t look too ridiculous wearing them in public.

From best to worst:

  1. B&O H6: Medium-sized design that folds flat and looks great. Excellent clicker, the replaceable cable can be inserted into either side, and another headphone can even be daisy-chained to the unused side if it has a cable that fits. Good neck-dropping.
  2. KEF M500: Small design that folds flat and inward and looks great. Replaceable cable, but the clicker’s buttons are squishy with almost no travel or feedback, making them frustrating and error-prone. Superb neck-dropping.
  3. B&W P5: Small design that folds flat and looks great, with a good clicker and replaceable cable (although the socket is internal, and replacement requires removing an earpad). Good neck-dropping.
  4. Bose QC25: Medium-sized design that folds flat and inward, optionally into its nice and compact case. Good clicker, replaceable cable. Fashion-neutral unless you get a custom color (don’t). Good neck-dropping.
  5. Master & Dynamic MH40: Medium-sized design that folds flat and looks great. The replaceable cable can be inserted into either side, but the clicker buttons are mediocre. Great neck-dropping.
  6. Sony MDR-1R: Medium-sized design that folds flat and looks good. Decent clicker. Good for neck-dropping.
  7. AKG K545: Medium-sized design that folds almost flat, although the cups are a bit large for neck-dropping. Mostly fashion-neutral, although the headband could be thinner. The clicker buttons are mediocre, but the cable is replaceable.
  8. Beats Studio: Medium-small design that society deems fashionable, with a good clicker and a removable cable. Only folds football-style, but it’s one of the smallest football-folders. Average for neck-dropping.
  9. Beyerdynamic T51i: Small, average-looking design that folds flat, but it’s heavy for its size. The remote is average, but the cable is not replaceable, and it’s inconveniently split separately into each ear.
  10. V-Moda XS: Small design that only folds upward, still remaining an awkward shape for bags. The cable is replaceable, but it only has a 1-button clicker. V-Moda’s industrial design is divisive; I find them ugly. Limited neck-droppability since the cups don’t swivel.
  11. B&W P7: A bit large and only folds football-style, but otherwise a nice-looking design with a good clicker and replaceable cable (although the socket is internal, and replacement requires removing an earpad). Limited neck-droppability.
  12. Focal Spirit One S: Medium-sized, but hardly folds at all — only football-style, and only halfway. In practice, you effectively need to carry it in its fairly large case. Fashion-neutral. Replaceable cable, but only has a one-button clicker. Mediocre for neck-dropping due to the medium-sized earcups that barely swivel.
  13. NAD VISO HP50: Big, below-average looks, and the worst clicker I’ve ever used, with almost no button travel or feedback. But replaceable cable can be inserted into either side. Limited neck-droppability.
  14. AKG K551: Folds almost flat, but earcups are much too wide, significantly impeding packing and fashion. Too large to neck-drop. The clicker buttons are mediocre and the cable isn’t replaceable.
  15. Sennheiser Momentum (Over-Ear): Medium-sized and good looks, but with an inflexible design that doesn’t fold at all. Replaceable cable with a great clicker. Limited neck-droppability.
  16. PSB M4U 1: Big, clunky, unattractive, and only folds football-style, not flat. Too large to neck-drop. The cable is replaceable and can go in either side, but the clicker is only 1-button.
  17. Beats Pro: Big, clunky, heavy, below-average looks, and the cups only fold upward, still remaining quite large. Too large to neck-drop. At least the cable is replaceable and the clicker is decent.
  18. Blue Mo-Fi: Very large, clunky, and heavy, still very large when folded, and with a divisive design; I find them ostentatious. Too large and complex to neck-drop. The cable is replaceable and the remote is good, though.

My favorites, overall

From best to worst. Prices are Amazon’s first-party price at the time of writing:

  1. B&O H6: $400
    A very comfortable, extremely stylish, and practical headphone for people who prefer light bass. More than any other headphone, it really nails the whole package: nothing else I’ve tried balances great sound, comfort, portability, and appearance as well as the H6.
  2. AKG K545: $260
    I’ve never heard anything this good for this price except the K551, which sounds slightly better. It fixes the K551’s biggest shortcomings: it’s smaller and more attractive, with removable cables and far less earpad sweatiness. But it’s not as comfortable as the K551.
  3. AKG K551: $260
    Very similar to the K545, but with more comfortable (although much sweatier) earpads, a non-removable cable, and a slightly more refined sound. Its amazing comfort and sound come very close to open headphones, including being a bit light on the bass. The extra comfort over the K545 is substantial, but it’s also far less suited for portable use due to the huge earcups and non-replaceable cable.
  4. PSB M4U 1: $250
    This was famously The Wirecutter’s pick. It’s a great choice for fans of laid-back sound, but if you like clarity and detail, it sounds boring and a bit flat. It’s not well suited to portable use, but it’s very good for long-term comfort at a desk.
  5. KEF M500: $250
    Surprisingly good sound and comfort for an on-ear headphone — good over-ears sound and feel significantly better, but you won’t find anything better that’s this small. And they’re practical: they isolate sound more than average (both ways), the earcups can fold either inward or flat, the materials are high-quality, they’re stylish, and their cables are removable. My only complaint is the squishy buttons on the remote. If you’re looking for a small, stylish on-ear and don’t mind a bit of muffled treble, stop here.
  6. Master & Dynamic MH40: $400
    A stylish, decent sounding, moderately comfortable alternative to people seeking H6-level fashion and materials with more bass. Its sound isn’t worth its price, but it’s better than a lot of headphones out there.
  7. NAD VISO HP50: $250
    Paul Barton designed the PSB M4U 1, then made the NAD HP50 as its spiritual successor, but it’s more like a 1.1 release than a 2.0. It has great enhancements in theory and is just as practical, with removable cables and a socket on either side, while adding a truly terrible 3-button clicker. It has more refined measurements and sounds slightly better than the M4U, making it the best implementation of laid-back sound I’ve heard. But comfort also got noticeably worse than the M4U, which is why I rank the M4U higher.
  8. Bose QC25: $300
    Bose’s new flagship headphones don’t sound very good, but their active noise cancellation (ANC) is the best I’ve ever heard — better than the ANC in the QC15, Parrot Zik, and Beats Studio. They retain Bose’s usual excellent comfort and light weight, and look less hideously outdated than most other Bose products — their designs have advanced from 1989 to 1999. If your primary goal is to dramatically reduce noise on planes or in a noisy office, I can recommend these, but the sound quality is poor for the price.
  9. B&W P7: $400
    Good overall, but not great, and not worth $400. Even if you like their laid-back tone, the M4U 1 does it better with better comfort for $100 less. (Of course, the P7 is much more attractive. But if I wanted a $400 attractive headphone, the H6 and MH40 both sound and feel better, too.) Tried only in store.
  10. Focal Spirit One S: $250
    Decent sound for the price, but mediocre comfort and poor portability make them hard to recommend over more practical alternatives.
  11. B&W P5: $270
    If you’re looking for an attractive on-ear, this is a reasonable choice, but the KEF M500 is better sounding, more comfortable, and more portable (and, to my eyes, equally attractive).
  12. Beats Studio 2 (“2013”): $250
    Much better-balanced and more detailed sound than I expected, but the ANC hiss and uncomfortable fit are fatal for me.
  13. V-Moda XS: $200
    Great sound for an over-ear, but poor comfort. My favorite thing about these headphones is the picture of my fluffy dog in my full review.
  14. Blue Mo-Fi: $350
    A unique, strange, complicated headband wraps a unique, strange, complicated headphone: while it can operate passively, it also has a built-in amp with two modes (normal or extra bass) that dramatically boosts volume, powered by a USB-charged battery.

    It’s an interesting but completely unnecessary achievement: the Mo-Fi in passive mode is sensitive enough to play far past my comfortable maximum volume from an iPhone, and the amp doesn’t noticeably improve the sound quality. It just adds complexity and weight, which are the last things this headphone needs, as the existing weight and headband complexity make them extremely uncomfortable and goofy-looking. The sound quality is also very poor relative to the rest of the category regardless of which mode the amp is in, attempting a laid-back sound but simply sounding extremely muffled.

    It’s an interesting attempt as Blue’s first headphones, but they’re seemingly too focused on making different headphones instead of making great headphones. Blue lent me a Mo-Fi for review.

  15. Beats Pro: $360
    These are great if you don’t care about comfort, only want to hear bass, and would like to set a few hundred dollars on fire. Tried only in store.
  16. Sony MDR-1R: $175
    Shockingly great comfort as you put these on is unfortunately followed by shockingly bad sound. By far my biggest disappointment in this review.
  17. Beyerdynamic T51i: $270
    I’m a big fan of Beyerdynamic’s great sound and amazing comfort, and the Tesla drivers have been fantastic in their higher-end headphones. The T51i is their first headphone with a 3-button clicker (they’re very late to that game), so I had high hopes. Unfortunately, these sounded awful and they’re extremely uncomfortable. I’d never believe they were from Beyerdynamic if they didn’t have the name printed on the side. I’m holding out hope for a T70p update with a clicker, which is likely to be far better, albeit far less portable.
  18. Sennheiser Momentum (Over-Ear): $250
    These look fantastic, but feel and sound awful. The laid-back sound is much better achieved with the M4U 1 and HP50, and the style’s not of much use if I can’t bear to wear them for more than five minutes at a time.

I’ll update this article and the rankings as I try newer models in the future.

  1. If you want the best sound quality for the buck, you usually need to go with open-backed (or simply “open”) headphones. The open (but uncomfortable) SR60 is probably the best value in the business, followed by the awesome DT-880, which is better than everything in this review in both comfort and sound quality. But open headphones are like screen doors: they let all exterior noise in, and more importantly, they let all of your music out. This will annoy anyone around you, so it’s extremely inconsiderate to use open headphones in buses, trains, airplanes, shared offices, or anywhere else near other people, and it’s irresponsible to recommend them without this huge warning. 

  2. No, I haven’t tried custom-fitted IEMs molded to the shape of my ear with the help of an audiologist. The extreme expense of such an attempt doesn’t seem worth the very high risk that I’ll still find it too painful to use, given my experience with literally every other IEM I’ve tried. (I also won’t accept a promotional freebie custom-fit IEM for the same reason.) My ears just aren’t compatible with IEMs. 

  3. Amps definitely make a big difference for power-hungry headphones like large open models and orthodynamics, but the differences are only obvious up to the point that they’re adequately powered. You rarely need to go fancier than the Magni 2 unless you’re crazy like me and fall in love with the HE-6.

    I’m still not entirely sure I’ve ever heard a difference in DACs except their noise floors. I think I can hear a slight improvement in dynamics between fancy DACs and my Mac’s built-in one, but I’m not confident that it’s not placebo. 

  4. The HE-560 is actually lighter than the Mo-Fi.
