Cons - noisy cable, limited long-term comfort, big plug, can be harsh and analytical dependent on source
The beyerdynamic DT 1350 has been quite the surprising headphone for me. As a reference point, most of my listening is with the VModa M100 (XL pads), followed by Grado SR60i, and Sennheiser HD558 mainly for movies. As a college student, I highly value portability and comfort, so I will be offering some direct comparisons to the V Moda M100. I enjoy a relatively neutral sound signature with a slightly elevated bass, but most importantly, a natural sound is important to me.
Build Quality and Accessories
The DT1350 appear to be very well built with a nearly all metal construction. No apparent shakes, rattles or creaks are present. The hinged headband is smooth and adjusting after a while is necessary to increase long-term wearability. The ear cup rotating mechanisms seem solid. Beyerdynamic offers a very nice carrying case with extra carrying space for adapters, splitters, and even my Fiio x3 (Gen1).
When comparing the V Moda M100--a headphone renowned for its build quality and transportability, I give high marks to the DT1350. The DT 1350's ear cups rotate flat for storage in its case. While it doesn't store in as small of a case as the M100, the DT1350's thin, flat case is more suitable for stowing in a backpack along with books and tablets.
My present standard for comfort is the Sennheiser HD558 which disappear on your head. The DT 1350 do not present this level of comfort. Their strong clamping force keeps them snug on your head, but they never truly disappear. I have no issues with the pads; however, the narrow gap between the adjustment mechanism and your ears makes it hard to adjust eyeglasses while wearing the DT 1350. Also, as noted in other reviews, this adjustment mechanism can be quite the hair-puller. The split headband provides moderate comfort, but the rear band develops a hot spot on my head long before the front one. Generally, I can get a comfortable 1.5-2.5 hours of wear out of the DT1350.
My first impression of the DT1350's sound was "wow, the BASS." As a headphone geared toward the professional community, I was not expecting the DT1350's bass. The DT1350's bass digs extremely deep, and is precisely controlled. I consider the V Moda M100 a reference for its bass quality and control. To my ears, the DT1350 trumps it. The DT1350 will rumble on certain tracks, even with my flat EQ. Kick drums kick and bass guitar notes thrum just as they should. To really put the DT1350's bass through the ringer, I played Nigel Stanford's Cymantics. The bass synth drop part way through blew me away, it's bottomless.
My next reaction to the DT1350 was its incredible detail. I could hear Lady Gaga's mouth open as she began to sing with Tony Bennett. As their duet continued, the strength of the DT1350's mids became clear. Vocalists come alive with detail and richness. Female vocalists such as Florence Welch and Adele sound powerful and full-bodied. Guitar work by the likes of Pink Floyd, Boston, and August Burns Red are crunchy and gritty when called for, but also soar into the treble also. Attack and decay on cymbals is quite good, but can be slightly abrasive and harsh at times.
The soundstage and imaging of the DT1350 is impressive for its compact size. Bands sound like they are playing in a moderate sized space, but larger orchestral numbers do tend to sound cramped or unnatural.
The monitoring quality of these headphones is excellent, and at times can be even too revealing for some consumer uses. Particular songs in my collection are revealed to be poorly recorded or mastered under the DT1350's lens. I judge this aspect to be a big positive, even if it means I cannot enjoy some songs. The DT1350 scales well with recording and mastering quality, as well as file bitrate. All listening for this review was done using my Fiio x3 Gen 1 and Motorola Droid Turbo. I suspect that the DT1350 will scale quite well with higher end equipment.
-The DT 1350's cable does have quite a bit of cable noise present when moving around a lot.
-Ear cup adjustment mechanisms must be fully retracted to fit in the case
-The full-sized 3.5mm plug with 6.3mm screw-on adapter are rather large for mobile use.

Pros - Isolation, Strong bass good mids & highs, Responds very well to amping, Portability
Cons - High clamping force, Non replaceable cord, Sound can be a little muddy & flat from phone/portable HO
Not much to say about these that hasn't been said. They really shine with an amp though. They sound very nice out of the Magni2, But to my ears they have more presence and just sound slightly better from my old Shellbrook Super Mini Moy. Comfort is acceptable. Isolation is amazing, I've used these on flights out of my old Sony A726, Very nice. Vacuuming while wearing these is a little spooky, I could easily kick the cord from the wall and not know. I bought these from amazon as a cosmetic blemish item for $129. I lucked out the out side box had some slight damage, but the inner contents were pristine.
Pros - Nice isolation, and ergonomics. Good packaging effort. "Honest" - Good materials sound awesome, bad materials sound like the crap they are.
Cons - Clamping a little tight, have to bend the frame to loosen a little. Microphonics a little irritating when listening in low levels. Mids can improve.
Decided to go shopping to buy myself a replacement for the Sennheiser HD25-1 which has served its purpose touring with me for the last 9 years. Auditioned quite a few headphones, and almost missed the DT1350. Thankfully I was not happy with the sound of the other headphones and headed to another shopping district and chanced upon the DT1350 on demo. Fell in love with the voicing. Had bad relationship with Beyerdynamics in the past, and hated the DT90, but the DT1350 won me over. Big time. Glad I gave the cans a chance, and fell in love. Well done, Beyer.
Mids could be more accurate in my opinion. The high mids somehow sounds a little off. I am used to listening to studio monitors and use them as a point of reference since I spent more than two decades in recording studios.

Observations after 1 week of using them
Isolation might be affected by the microphonics especially when used in flights/trains. While they are closed cans, they are still better used at home rather than outdoors. Else one will be left guessing where all that "rumbling, second bass note, etc" are coming from. I was hoping that Beyerdynamic and all the headphones company learn something from Westone... BRAID YOUR CABLES!
Geesh... If you are making something portable, consider the microphonics!
Fit is better than it was a week back, and I am loving the seal and how the sound is smoothing out... funny how cars and cans have in common... the "first thousand clicks" to burn/run it in.
I still love the voicing of the DT1350 but this is personal, rather being a "this is the best sound". Because there is no such thing. One man's meat is definitely another man's poison when it comes to preference for sound.
Nice and meaty mids, soundstage still not as open as thousands of other cans out there. If you want an "intimate sound" like listening to a pair of near field monitors in a quiet room, this pair of cans will make you smile.
Make sure you audition a pair of burnt-in cans though... new from the box, they can be a little disappointing.
Aesthetics build, so-so, there are prettier cans out there. Lots of nicer looking ones. These are industrial looking but they get the job done. And comfortable. Wore them for most part of a 12 hours flight, and I was not sore when I landed. That is a sign of a good fit. (I am of medium build).
- - -
(more observations, average listening per day : 4 hours. Can burn-in time : over 200 hours).
The fit is less clampy now. I would say comfortable but you still feel it there. The pads softened as mentioned by the others, and the seal and sweet spot is easier to find now. (Had that "where is my bass" moment before the pads softened). Microphonics still a problem, and would be looking at a solution at some point when I can get some nice braided cables to replace the stock ones.
The voicing of the DT1350 makes me happy, because it reminds me of the Quested speakers I used to love so much in the early years in the studio. The mid range is beautiful, in my opinion. And the low extension is enough for me to enjoy what the bassman is playing without having to feel like I am standing beside a bass amp or subwoofer. Highs can get a little bright but matching with the TEAC HA-P50-B smoothes them out. The DT1350 does not match well with the FiiO E17+E09K combo, as the amp/DAC brings out the worse in the cans. Mids become hollow-er, brights just get brighter... not good at all.
The high frequency response of the DT1350 is really good, and I love the fact that I can pick up all the subtle strings, vocal parts, harmonies, etc. in the recordings. Behaves a little more like the ribbon tweeter monitors at the top end. But for me, the overall voicing works very well. It has the "typical British sound" that I love. (This is an old school reference).
I don't think there is much to add about the "stock version" of the DT 1350. If I get to "upgrade" the very noisy cables, I will come back and post again. Otherwise, this shall be the last update.
If one likes clarity and a neutral sounding pair of close cans, with an intimate sound close to your ears, this is probably one of the best cans out there. Not really on the cheap side, but it will be money well spent.
- - -
(more to come if I manage to find material and time to replace the stock cables)
Pros - Durable, very transportable, good clarity, decent musical versatility
Cons - Uncomfortable, slow impulse response, prone to unnatural-sounding instruments

I'll admit it upfront, I haven't exactly been a fan of Beyerdynamic's headphones so far. The 2005 DT880, 2003 DT770-80, 2003 DT250-80, T50p, T1, and T70 have all been disappointments to me in one way or another. But when I started reading the raving on the DT1350 last year, including by Tyll Hertsens (of InnerFidelity.com), I decided that I had to hear them for myself and ordered up a pair in November 2012. This review is hence based on approximately 5 months of ownership (Nov '12 - Apr '13).

Pros & Cons
+ Hang-able on the neck (because you'd be surprised at how many closed portable headphones can't be worn around the neck!)
+ Split headband allows for a greater degree of comfort than a single-piece headband
+ Extremely transportable with the supplied carrying case
+ Very good overall sound quality and versatile with multiple genres
- Supra-aural clamping pressure created a lack of comfort during extended listening sessions (i.e., caused ear soreness)
- Not really efficient enough to get loud enough out of portable sources at medium settings
- Relative lack of clarity
- Slow impulse response
- Uneven frequency response leading to some unnatural-sounding instruments (like string instruments)
Computer & Portable Applications
For computer audio in general, I found the DT1350 to be an overall strong performer, but crippled by its lack of comfort for long usage sessions. I frequently had to take them off due to discomfort approximately every half-hour or so, primarily due to the supra-aural clamping pressure from the relatively small-diameter earpads. If the earpads were larger in diameter (close to the diameter to that of my Audio-Technica ES7), it probably would have increased comfort substantially.
Overall the DT1350 did well with movies & games - specifically the action-based material that I tested it with. Explosions were decently boomy on it, and it seemed to have accurate-sounding gun reports too - importantly, automatic gunfire having quick-sounding reports (I'm sort of a stickler on automatic gunfire sounding fast). It had a fairly open-sounding soundstage too, which worked well for locating enemies by ear. In fact, it was a significant improvement over my ES7, which has a flat soundstage and doesn't work well for locating enemy positions by ear.
As far as amplification, the DT1350 seemed to sound nearly as good out of my PC (through a headphone jack on my PC speakers) as it did on my reference audio CD system with dedicated headphone amps. Although it did sound best out of the Burson Soloist, it wasn't really a huge difference from out of my PC. It sounded just about the same on my portable DAP (iAudio X5) as well. The only thing that I really noticed with the iAudio X5 was that the DT1350 wasn't very efficient, as I had to turn up the volume past 20 (out of 40) for it to sound loud. In comparison, my JH Audio JH13 IEMs were slightly louder at 17-18 than the DT1350 got at 22-23.
Critical Music Listening
Honestly, the DT1350 wasn't particularly "excellent" or outstanding to me, and I wouldn't use any superlatives to describe its sound. However, that's mostly because I've heard headphones that are way better than it, that are also more expensive (some a lot more). I'd class it as "average" in my overall ranking of headphones, in the company of others like the AKG K2xx/K70x, Senn HD6xx, and the Grado SRxxx/RSx lines. So if those other headphones impress you (or would be upgrades from whatever you currently have), then sure, I'd recommend the DT1350. However, if those don't impress you, or you already have something like the more-expensive Senn HD800 or Audeze LCD-2 (or something else comparable), then the DT1350 likely won't impress either.
However, just because I call the DT1350 "average" doesn't mean it's bad - I only say that to provide a frame of reference against headphones that are both worse/cheaper than it and better/more expensive than it. In fact, I thought it sounded very good, better in many ways than a lot of other closed portable headphones that I've heard over the years. It was decently clear-sounding, with a good frequency balance (recessing primarily the upper treble & lower bass), and provided just enough satisfaction that I could use it for a decent variety of genres. There were actually only 2 genres that I thought weren't very good on it - electronica & classical. Primarily because the DT1350 lacked general bass quantity and extension to really provide a satisfactory impact for electronica, and it effectively reduced large orchestras to sounding small & smashed-in. It added a somewhat unpleasant bronzy/nasal character to violins, brass, & woodwinds too.
For my other genres though, like bluegrass/folk, rock, & metal, I found the DT1350 to be very good-sounding - and could believe that it'd even be potentially "great" to those who it would be an upgrade for. I'd sum it up as a semi-assertive- & clear-sounding headphone (not too different in style from the Shure SRH840/SRH1840) without distracting mid-range colorations (like forward vocals or anything like that), and relatively mid-range- & bass-light. And definitely closed-headphone-sounding too - i.e., it had a compacted soundstage not unusual for closed headphones, but fortunately the soundstage wasn't too small either, as it was deceptively large for such a physically small headphone.
I'd say the DT1350 would be a sonic upgrade from the following headphones specifically (all of which I've owned/heard): Audio-Technica ES7 & M50, Creative Labs Aurvana Live, Sennheiser HD419, Shure SRH840, and Sony MDR-Z700. Moreover, I recommend it for anyone looking to buy a set of closed portable headphones for the first time. Beyerdynamic has finally made a headphone that I can get behind for once! Granted, it doesn't exactly win sonic awards from me in the grand scheme of things though - let's just say that if it cost twice its $300 MSRP, I would've been a lot more critical of it and wouldn't be purposely glossing over the sonic nitpicks that I have with it. The best praise that I can give it is that it sounds like a $300 headphone. I can't think of any better closed portable headphones at its price and I'd call it the best new headphone of its type currently available for combined computer & dedicated music applications! I was actually more impressed with it as a computer headphone though and it'd be my first recommendation for anyone seeking a computer headphone since it combines moderately good sound with a very good level of isolation. It's easily the best "office cubicle"-type headphone that I've ever heard and if that's your intended use, then buy one now!
The best way that I can spin the DT1350 would be to call it something like a closed version of a micro-HD800. Not "mini", which would be stretching it a bit for me, just "micro" along with everything that implies. Not that "micro" is bad - in the case of the DT1350, that's actually a good thing!
Comparison: V-MODA M-100
I found that the DT1350 and M-100 sounded somewhat opposite to each other - the DT1350 being substantially clearer-sounding with less mid-range and bass overall than the thick- & full-sounding M-100. In fact, if the M-100 is considered bassy (as many people claim it is), then the DT1350 was definitely bass-light compared to it. However, while I thought the M-100 had very good bass and mid-range (with especially nice, full-sounding vocals), it was also somewhat suffocating-sounding to me, as if it was literally trapping the music within its confined driver chambers, while the DT1350 had more of a spacious (i.e., "airier") and spread-out sound. Its diffuse presentation was definitely a plus for certain music genres, as it allowed music to sound spatially bigger than the M-100 did. Nothing sounded too up-close with the DT1350 either, as opposed to the M-100 which was very up-close & intimate-sounding.
However, in the grand scheme of headphones, neither the M-100 or the DT1350 impressed me by their sound quality all that much, but that's only because I've gotten used to some very good-sounding headphones in recent years like the Audeze and Sennheiser flagships, including my previous high-end electrostatic system (Stax OII & BHSE). But at the $300 price point, it's hard to find better than either the DT1350 or M-100, and I think the choice of headphones comes down to the type of music you listen to and what kind of sound you like. I view the M-100 as the more obvious choice for most listeners of contemporary music genres who favor bass - pop, rock, metal, electronica, etc. The DT1350 might be the better choice for those who don't care as much about bass quantity and listen to classical or generally acoustic (non-synthesized) music. I'd go even further to say that the DT1350 and M-100 are sonically-clear byproducts of their respective manufacturer's geographic regions - Europe for Beyerdynamic, the USA for V-MODA.

Addendum - Review Notes
My review notes are included here in their own section for convenience. These provide specific detailed info not included in the review. Notes start below the asterisks.
Far Cry / Half-Life 2: Clearer than ES7, and just about as fast - quick gunfire and satisfying explosions. Better imaging - sound field more spread out which helps to locate enemy positions by ear. Also easier to hear layered effects like footsteps, etc.
Trifonic - Emergence: Lacks overall "dimension" to the spatial image, so this type of music (ambient electronica) completely lacks the "empty-space void" feeling. Spatially flat-sounding - almost no sense of "air" within the music. Very closed-in sounding; however, this type of sound not unusual for closed headphones in general. Acceptable spatials for a closed headphone, could be worse. Also lacks some clarity, though treble and bass quantity is decent. However, treble lacks precision. Bass also lacks depth & general quantity (below 80Hz).
AKUS - Paper Airplane: Intimate-sounding but lacks a presence factor compared to flagship headphones - doesn't sound very "physical/existential". Lacks center fill in the imaging. Also seems to be somewhat "dead" sounding - no vividness to sound, and no particular emphasis anywhere in the spectrum either. Relatively neutral though.
Megadeth - Countdown To Extinction [MFSL]: Front-loaded/forward male vocals not a detraction here, helps make the music sound more "metal". Assertive-type sound - neither "aggressive" or "passive" per se. Reminds me of Shure headphones in a way. Background details either lost in mix or blurred.
Helloween - 7 Sinners, In Flames - The Jester Race: Good drive, overall very appropriately-assertive sound for this type of music. No obvious emphasis on either bass (instruments) or guitars. If anything, guitars somewhat in background compared to most treble-heavy headphones (sort of like a counter to the Grado-like sound). Not really fast enough to keep up with fastest speedruns though, and relative lack of clarity subtracts from the enjoyment. Small-ish soundstage does work great for this music type, provides a good "up-close w/ band" feel.
Goldfrapp - Black Cherry: Bass lacks drive and ultra-low extension. Relative lack of treble quantity as well. Female vocals sound only ok, nothing noteworthy. Again sounds "dead" - lacks a spark to make it engaging, reminds me of K701 in that aspect, which also sounded dead.
The Crystal Method - Tweekend: Bass in general acceptable for this music type - decent impact & quantity. Easy to hear bass, even if it doesn't extend very low. Not enough bass though to truly satisfy like an Audeze.
Massive Attack - "Teardrop": Bass rolled off, notably on the heartbeat rhythm (lowest notes inaudible). Also lacks a heavy/fat presence. Texture/slap of kick drum also muddled, not very easy to tell it's a kick drum.
Julia Fischer - Bach Concertos, Carlos Kleiber & VPO - Beethoven 5 & 7: String instruments not very clear-sounding. Lack of soundstage depth distracting but not a total dealbreaker. Because of the "closed" nature, music sounds a bit stuffed-up/suffocating. Decent balance overall between sections and frequencies - no major flaws. Violin treble level acceptable - not too much, not too little. Strings overall nasal/bronzy-sounding, consistently initially off-putting on every listening session. Not really ideal for classical music due to off-putting frequency balance (the nasal/bronzy sound) and lack of clarity. However, not terrible either - just acceptable enough.
Seems to have a slight "veil" over everything as well. Not as "transparent" as it could be and has a slight "muffle" factor that especially affects guitars (especially overdriven guitars).
Overall: For the cliché "I hear more details with xxx new headphone!", the reverse is true for DT1350. The details that should be on the music test tracks weren't there on DT1350 - i.e., "With the DT1350, I can't hear the details that I know are there!". Not bad, but not great either. Squarely decent, acceptable for price and for being closed - hard to get a decent-sounding closed headphone in this price bracket. To that point, above-average considering the other options of its type in this bracket.
Also scales with amps somewhat - sounds substantially better on Soloist than on Magni. Most obviously clearer throughout the spectrum, with improved soundstaging as well (more depth & width).
Pros - Good build, easy to remove and rest above ears or neck, isolation
Cons - short cord, unremovable cord
I didn’t realize that these were an on-ear design until after I ordered them. I was kicking myself as I knew they wouldn’t be to my liking with the whole isolation thing’. I almost requested an RMA before they even arrived. However, when they did arrive I just had to open the box and again, I looked into the pouch and saw those diminutive cups while I gently shook my head from side-to-side. Even so, I decided to try them.
At first I thought that I was trying to force myself that they were not that bad. But then when I started to listen to them and also to feel how they molded to my years, I noticed that they were quite comfortable. Also, the isolation is considerably better than I imagined, even for my home studio broadcasts. Anyway, I decided to keep using them and sheepishly, I realized that I had profiled these cups in a negative light.
Overall, I think these are keepers’ as the sound is great; the fit is comfortable, as they don’t sweat your ears, and they’re easy to dismount onto your head above your ears or rest on your neck, as the cups turn flat. Another perk is that they don’t over-power my bald head and that’s important when I may use these during a video webcast. Also, they have an 80-ohm resistance that tilts them away from strictly portable use. I could easily connect these to my channel strip once it arrives. This is not to say they can’t be used on my iPhone because they can.
Ok, I do wish it had a longer reach than the non-detachable 5-foot cord provides. In any event, I’m more satisfied than not.
Cons - Clamping force, uncompromising with inferior sources
Oh my. If this is how beyerdynamics builds their stuff, then I WANT MORE.
These are the perfect complimentary 'phone to my Sennheiser Momentums. Both are built like tanks, but the sound qualities are so different. Where the Momentum is warm and forgiving, the DT1350 is cold and analytical. Where the Momentums are mid-centric, these are flat. Where the Momentums have character (good character), these are robots.
This is the best analogy: the Momentum is Kirk, and the DT1350 is Spock.
I am a scientist, and love quantitative data to back up claims, but the frequency response curves for this headphone does not tell the whole story. I can tell you, as a former recording musician and possessor of a very sensitive ear, that these are as accurate as 'phones get in the under-$1,000 category. The sub-bass is strong and punchy, but not overdone. Bass is strong and present, but, again, not overdone. Mids are not recessed, but not overdone; very smooth. Treble: what a revelation! You can have treble, and plenty of it, but it doesn't have to be sibilant and piercing! Amazing! I was startled several times when I heard Paul McCartney breathing whilst singing on "She's Leaving Home". I really thought my wife was trying to talk to me - because I can't hear a darn thing with these on.
I didn't like the AKG K550 because it was too piercing, but I loved the accuracy. This is like the K550, minus the extreme pickiness of placement (although take your time with these) and fizzy highs. If you need a headphone that makes everything sound good, get the Momentum - it's seriously amazing. If you need a headphone that makes everything sound exactly as it was meant to sound, get this - it's seriously amazing!
They're pretty great. The sound is very detailed. They're very durable. One con. They start to make my ears ache after a couple hours. Isn't it great how I said the exact same thing in the pros/cons bar?
DT1350 is a very unique headphone with a warmish natural sound. I am yet to hear anything like this. It has very punchy as satisfying bass, rich yet not too forward mids, and smooth and extended highs. However, what is important is the clarity and detail. DT1350 is better than SE535, costing $200 more, in terms of detail and clarity.
About myself: http://www.head-fi.org/t/674373/story-of-a-new-reviewer-kimvictor
Here is by break down:
Sub bass: Well extended and deep
Mid bass: Punchy and impactful
Lower mid: Slightly thick and rich
Upper mid: Clear and slightly forward
Lower treble: Clean and detailed.
Upper Treble: Well extended and smooth, but lacks air.
Soundstage: Small. More like an iem than a headphone.
Clarity: Very good. Although not at the level of SRH940, it's better than SE535 and M50.
Detail: Very good as well. One of the best details I've heard. Slightly less detail than SRH940.
Isolation: Good. Almost iem level isolation, but comes with sacrifices.
Clamping: This is the sacrifice. It's tight. For the first month, I felt pain in my ears, but it's getting better.
Source/Amping: I didn't think that it really benefited much from Magni/Modi, but it may be due to bad synergy. I'll report back once I have Leckerton UHA-6S MKII.
Just last week, I decided sell most of my gear besides ones I love to fund a amp/dac for my UERM. I sold SE535, AD700, M50, X20 and kept SRH940 and DT1350. There is a clear reason. They are just simply class above everything I've sold. Very impressed.
Update: For got to mention other portables. I was also looking at momentum, hd-25ii, and esw9a. Momentum failed as it was bit too bassy and didn't have that mid I was looking for. It did have pretty good clarity and detail. HD-25II seemed fun, but didn't fit with my acoustic music. ESW9a was most considered, buy it had rather bad clarity, so I dropped it.
Also, I have to mention that DT1350 sounds very full, which is a good thing for me.
Thankfully, it pairs well with Leckerton UHA-6S.MKII. These Leckertons are awesome. They deserve more recognition.
Siblilance: DT1350 is the least sibilant of all gears I own. Amount of sibilance is similar to HD598, which has close to 0 sibilance.
Price on these are dropping! New version of them are out. They have bigger earpads, replaceable headband, and coiled cable. No difference in drivers though. I'm adjusting the value because it's cheaper now!
I have this headphone for a year. I must say that this is the greatest close-sealed headphone I have ever heard at the level of $300.
Some people say DT1350 isn't comfy at all . At first ,I had the same feeling about this. However, as time went by , DT1350 become more and more comfy.
At sound quility , I think it kick HD-25 sp ii's ass. It's treble and mid have lots of energy impact , and it's bass is deep . It's very nuetral and balanced ,so It suits well with people who love to listen all kinds of music.
Although it is unfair to judge this size of headphone (closed) , it's sound stage is small . You need to require more effort to imagine a stage (and it sounds like you're on stage).Besides,it doesnt have too much bass.
Easy to drive enough sound (130 SPL ) and have greater performance with amp.
Highly recommended for building a mobile hi-head system.
