Sennheiser HD 25-1 II Professional Headphone

I like them.

I bought them as an upgrade for HD-215. I needed better isolating headphones because of the noisy environment. I was trying several models (Technics, Pioneer, AIAIAI,...) and I loved these the most. Sound quality is #1 reason for me. They might be not the best looker but I use them as all-round headphones while commuting, DJ-ing, at studio or at home. The only downside I found so far is they are little bit uncomfortable when wearing for a longer period of time, especially together with glasses.

This is my reference for what a portable closed headphone should be.
It's neutral and sounds good on all genres.
It's not a giant killer like the DT531, but keep in mind it is closed and portable and has the most durable build quality of anything I've seen.
Also, it has the cheapest, most cost effective upgrade available for it, the upgrade to an HD650 cable.

In my opinion it is the second best deal to be had in headphones for a beginner to this hobby, second only to the Beyerdynamic DT531, if you can find it.
The Beyerdynamic DT531 has better high range sparkle and soundstage, but less midrange realism, depending on the genre you're listening to.
Anyways, neither are a perfect headphone, and calling either a giant killer is an exaggeration.
What I mean by that is for someone new to the hobby, the Beyerdynamic DT531 and Senn HD25-1 are just an amazing deal in terms of price: performance ratio.
Yes they are bested by even mid-fi headphones in the $600 range. But considering the price you can find these for used, I'm not sure I'd recommend someone to 'upgrade'  and spend 500$+ an amp if they're happy with the sound.

Listening to John Coltrane - A Love Supreme I preferred the HD25-1 to my HD650 balanced system powered by a Beta 22/Lavry DA10.
The HD25-1 has a seriously sweet midrange for being as neutral as it is. Tonally accurate, yet easily heard in the music, almost 'highlighted'.
This mysterious midrange quality is it's greatest strength and the most stand-out part of the headphone followed immediately by it's tight, tuneful base.

Now for the negative part. Over time the closed in soundstage makes them less fun to listen to. It kind of builds on you over time and threatens to distract you completely from the listening experience.
But if you listen while doing other things, like snowboarding or skateboarding, biking, you don't notice this.

That's all I really have to say for negatives. For the right person, these are the ultimate portable and rugged, yet amazing sounding headphones.
If they redesigned the arc assembly so that the headphones folded outward when sitting on your neck, we'd have a new FOTM (flavour of the month) on head-fi.

Design/durability: They look professional. As for the build quality, these are certainly the most rugged headphones on the market. It is practically indestructible, and if a part comes to break it is possible just to replace the part itself (ear pads, cable, headband, you name it). They can be thrown in a bag and not be worried about. Designed to last a long time, if not a lifetime.
 
Fit/comfort: Average. Many complain about the clamping force of the HD25, but I find it to be okay after a few months using them. The headband becomes more loose and flexible, although it still has more pressure than on other headphones. Definitely not the most comfortable cans around, though.
 
Isolation: Among the best headphones when it comes to this aspect. They don't equal IEMs, but still have a superior isolation to most other headphones of its category. Good for outdoor use, even for air travel, unless you fly a very noisy turboprop.
 
Sound: Excellent, and still a reference despite the years. The sound signature of the HD25 is rather warm (V-shaped), and very revealing from bottom to top frequencies. The bass has a nice texture to it, and sounds fast and powerful. Mids are slightly recessed but they remain neutral, not colored. The treble is bright and slightly aggressive. Also, the HD25 have a good amount of energy in them, an almost dynamite-like punch that can handle any fast track. On the downside, soundstage is quite small although imaging is good. The HD25 provide an enjoyable, dynamic and polyvalent sound with a fair amount of details.
 
Bottom line: A classic that remains a classic, and a good bang for the buck guaranteed. Mine are 8 years old and still going strong.




HD-25 retrofitted with velour pads

I love my HD25-1 II Headphones. They are, in my opinion the perfect portable headphone. I am not a huge fan of on-ear headphones but I do quite enjoy them. The sound quality is addicting, they are easily driven by an iPod or iPhone and have quite a bit of low end (perfect for modern electronic music), but when put on a proper amp the low end levels out the headphone becomes much more accurate.
 
The only real problem I see with them is they have quite a clamping force and when put on with glasses can become very uncomfortable. I use them for a max of 2 hours.

Durable - replaced pads after two years - i use case supplied with phones for storage

I'll make this clear - the sound signature of these headphones will not blow you away. I was expecting a lot from these (after reading the many positive reviews) and when i first listened to them i felt a little underwhelmed.
 
We've all had that experience where we listen to a piece of music and think...meh it's ok - and then months later you're putting in your top 10 all time favourite list. Well i've had the same experience with these cans. I have grown to love them!
 
 
Design - They're lightweight, surprisingly portable and have a minimal look and feel. They can be used as DJ headphones due to their tilt cup design (the left headphone can be tilted away from the ear). They are also modular which means you can replace the parts if they ever go wrong.
 
Comfort - At first these things did hurt my head and gave me a bit of ear ache when listening for long periods. However after about a month of use, the comfort significantly increased. The clamping force became much less intense and i can now wear them for many hours.
 
Sound Quality - As i've already mentioned, the audio quality will not blow you away. These are a neutral set of cans with an emphasis on detail and clarity. The sound stage is lacking and some tracks can sound a little flat. At first i thought this was a bad thing, but soon i began to appreciate the purity in the sound that these headphones offer. Give them high quality audio and you will hear every bit of detail. What puts the icing on the cake though is the instrument separation - this is what these headphones do best and at very high volumes too (i sometimes DJ in a club where the booth is ridiculously loud and no matter what the volume is - i can always make out the low, mid and high without any bleeding of the sound).
 
Bass - A little more emphasis here, but they never overwhelming and sound punchy rather than warm
Mid - Clear and neutral in texture
High - Clear without sounding bright (not fatiguing on the ears)
 
These headphones are great for electronic music (house, techno, tech-house) and sound great with older flavours too (trance, progressive etc.)
 
Value - Not that cheap and even though they're modular in design, the parts are pretty expensive. However these things are build like a tank, so in my opinion they justify the price tag.
 
 
9/10 - i absolutely love these headphones and recommend them to anyone who is looking for a closed back design.

These headphones are great. I listen to mostly metal and have listened to Grado's mostly because of it, and these phones are really similar to the grado sound; I can see why people refer to these as the equivalent to a closed grado headphone. It's funny to me how different these phones are to the description of every other sennheiser headphones. Every review for the hd 600 or 650 talks about their laid back nature, while the hd 25's are anything but laid back. indeed, they are very forward, and for metal and rock, this is just what the doctor ordered. Bass-y music sounds great too, these headphones can really bring out the lower end of the sound spectrum. My only gripe with them is the initial comfort - it takes a bit to get used to the amount of pressure they put on the ears. After owning them for over 3 weeks now though I can say that I love this set. While its hard to argue with the portability of IEMs, these guys just sound so good I am willing to give up a little more space in my backpack when i need to store them.
 
Highly recommended, especially with the velour pads!

OK I've never reviewed headphones before but think that the Sennheiser HD 25-1 II are the perfect set to start out with, I really love these headphones, I think they look good and as for sound quality they are really great all round performers, great bottom end, good mids & good tops. I'm not gonna get technical with bright, dark, veiled, sibilant etc etc. I'm not good with all these terms, my ears tell me I like them, I wouldn't say they were sound perfection but I've yet to find a pair that could be described that way. I actually own/have owned many headphones, all of them have some kind of flaw. If I had to describe the flaw with these I would say they have a 'very slight screechy sound' but they do make up for it with their excellent sound quality & general performance, as I said before personally I think all headphones have some kind of flaw. I hope that my description doesn't put you of because I honestly think these are one of the better headphones available and out perform many at twice the price.
 
Nowadays I see more and more people wearing them in the streets & I think to myself these are people who care about how their music sounds, I got my first pair in the late 90's for DJ purposes, They are unbeatable. I've dropped them hundreds of times, the worst thing that ever happens is the ear-cups fall off, you just clip them back on again and your back in business, I've trodden on them more times than I care to remember, they've been literally ripped from my head when some fraggle went & got caught up in the cable (this has happened more than once). The cables are really strong. Durability wise these headphones are in a class of their own,
 
Comfort: They are tight but I wouldn't say excessive, they're not going to fall from your head, I always use them when I'm on my pushbike, safe in the knowledge that they are safe and secure. Sometimes I remove them for a few seconds to give my ears a break but in my opinion they're a comfortable fit, I like the way the headband separates, with a little bit of adjustment you will find the fit that's best for you.
 
As for portable audio once again I reiterate these are great headphones, they are of low enough impedance to perform well when plugged into an iPod. They are even better when plugged into an amp or my little Hisoundaudio Studio-V (DAP). Yes I do recommend them but I am biased because I totally am in love with them.
 
Bottom line... You can't go wrong with these headphones, they are highly sought after & have a high resell value, they make men look wise & women look sexy.

No review quite yet.

When I first received the HP25-1 II I was a little disappointed. They were tight on my head, to bright for my liking and bass was a little lacking. Right out of the box I was comparing them with my HD280s and felt that the 280s were better in every aspect except ergonomics. After a couple weeks of use I got used to the fit and started to notice the presentation was improving.
 
I actually fell in love with these headphones at CanJam 2010. Up till this point I was driving the phones with my ipod. I had read some reviews and an amp was recommended so I was on a mission for an amp. After many amps and comparing these phones with the best of the pack I can honestly say that they hold there own with the bid dogs when they have the right source and amplification. They have nice bass response and the highs were no longer overpowering. Overall I would say the sound spectrum is very well balanced.
 
There isolation is great when I use the phones at work or play. They stay on your head what ever activity you participate in, and when someone is trying to speak with you, you can easily pull them off to one side and listen. They have a rugged build and I suspect they will last for many years no matter what your activities are. Parts are readily available and the phones have a very simple construction so they are easy to work on and modify if you so desire.
 
Final thoughts. These Great little phones don't come alive until they have been burned in and are given a good source and amplification. The fit takes a little getting used to so give them some time.
 
Highly Recommended.

I never thought that there's such a headphone like this existing! Everything that I'm looking for for a headphone, I found it all on this hp. Cool looks (at least for me), changeable parts (especially the cables), superb clarity with excellent bass response, and lastly, known for its superb durability.  

I bought the Sennheiser HD 25-1 (adidas) after my ATH-M50 had a loose connection and i had to return them.

Though I loved the M50's, they made me realize that a headphone is not all about sound quality.
Their isolation just didn't do it for me, and the pleather pads got my ears sweaty all the time.

The HD 25-1 finally does everything I need it to do.
The isolation is top notch, and the velour pads are more comfy then pleather while not getting sweaty.

Sound:
The sound quality of the HD 25-1 II was horrible out of the box, but they got better after a few minutes.
I didnt notice much of a burn-in process after that, and was quite disappointed with their sound, cause the only thing they did better then the M50 were drums and bass, while lacking a lot in highs, detail and especially soundstage and imaging.

After two weeks of frequent use and over-night burn-in (~200 h) they suddenly made a BIG leap in sound quality and especially detail and extension.
Compared to the M50 they sound more refined and detailed while also revealing a lot of bad recordings/ sources. the impact on drums and bass is just heavenly, like the overall bass response.

The only thing they lack compared to the m50 is imaging(not existant) and soundstage.
But since I use them as portable headphones mainly, that doesn't bug me at all.

Conclusion:
the hd 25-1 is a really decent hp and definitely one of the best portable headphones.
I especially love the user customizable style, cause i don't have to worry what might happen if my warranty were to run out.

If you find the pads to be uncomfortable, wash them in warm water. It makes them smoother and allows a better fit and comfort for the head.

I have previously owned a lot of headphones, but I felt the need of an all-in-one solution that I could use at home or on-the-go. So I scoured and found that the Sennheiser HD25-1 II is the perfect headphone for my needs. It is a small, supra-aural pair of headphones with superb sound quality in its price range and category.
 
Construction:
The HD25-1 is a very rugged set of cans. Although lightweight and looks flimsy, it actually holds well against constant abuse and wear. The split-headband design allows for both a secure and comfortable fit, perfect for lengthy listening sessions. The earcups themselves are made of hardened plastic, and do not easily scratch or dent when hit by an impact force. Lastly, the provided stock steel cable has great tensile strength to maximize longevity. All of these parts are easily replaceable, so the headphone can last for years and years of usage.
 
It may not be the best when it comes to isolation, but it does its job well in blocking out external noise like the bustling city, airplane engines, and so on. Although the clamp is fairly tight, it's not as bad as the one from the AKG K518 DJ. The pleather and velour pads also add to the HD25's comfortable fit.
 
Sound:
As I write this review, I have already clocked in about 200 or so hours with this pair of cans. Overall impression, the HD25-1's sound quality is excellent for a closed headphone. Although there is some slight sibilance in the high treble frequencies and soundstage is a bit closed-in, it still sounds great straight out of a DAP or from a headphone amp.
 
It retains the classic Sennheiser laid-back house sound, but adds a generous bit of Grado's upfront, edgy kick to it. The result is a pleasing mix of smooth-yet-aggressive sound signature that's hard to come by in other headphones; it reproduces lush vocals, deep, controlled bass, and detailed highs for a can of this size and type. Suitable for almost all genres of music, the Sennheiser HD25-1 is a very flexible can that's sure to please a lot of people.
 
Conclusion:
Although a bit pricey at $199.99 in most stores available online, in my opinion the Sennheiser HD25-1 is a great buy in this price category. If you are looking for a portable headphone with sound quality rivaling full-sized cans, I strongly recommend getting the HD25-1's.
 
PS: I have included pictures of my HD25-1 II as seen in the product photos, to better judge its design and construction.

Being a non-professional, but a general music lover, My review will probably be in layman's terms, but why not. It will give the perspective from someone that observe music in a different way than the purely analytic fashion.
 
Once, I had a great home stereo consisting of NAD CD-player, amplifier and B&W speakers with some fancy cabling. -So I am not completely rookie regarding what sounds good and not. Neither am I a person that thinks that resonating boomboxes (cars) driving by is coolz because of lotz of basz. I like to hear all kinds of music. Anything from Mozart'ish music to music 'designed for serious PA-systems'.
 
Being without my stereo for the longest time and getting tired of the 'noise' rendered by my speakers integrated in the laptop, I figured out it was beyond due time to get myself some headphones. Getting a proper soundsystem is out of the question due to limited space and girlfriend.
 
First problem was: What am I looking for. Go for a pair that is more fitting for the stuff you listen to the most. If You only listen to classical orchestras and alike, I guess You should stop reading. You need to look for stax-phones. Very Expensive. Only worth having if you are a feinschmecker.
My playlist when trying out music is stuff like Deep Purple, Child in Time, Roger Waters Amused to Death, preferably the whole album. Nina Simone, Feeling good, Peggy Lee, Fever, Jazz, Blues. That kind.
That'll tell me wether there is bass at all, if there is decent mid-range, and also if the treble is non-offensive.
 
By reading a lot of reviews, these phones came out pretty good. Although! -The impression I was given by other reviews were that they were a little expensive compared to the sound given. This was when my critically inclined mental alarmbells went off. Things like being warm, 'muffled', having a 'veil' between the music and ear, making the music feel distant. I then recalled the good old days, where I built my own speakers, -the horror of screwing up the expensive hobby project, just to later have that Aha!- feeling of having to actually 'run in' the speakers before they are able to show off what they are good for.
 
Eventually, I decided for  these ones. I know Sennheiser from before, and I have never had/heard about any real issues about them before, Not being tempted by any fancy modern bling with buttons, sliders and glossy paper/plastic, I found a dusty box pushed in the back of the shelf.
 
The reviews were per se correct. warm, muffled, not very precise music. -So I bought them.
Day one. One big ''Meh. I exchanged the fake skin pads with the velour ones. Much more comfy.
and playing music, wearing them for six hours, before my ears got physically tired. I have a small head by the way. If you have a full size head, perhaps consider something else. They are a little tight, but I am trying to expand the headband(s) a little by the use of something wider than my head. This is probably the only minor con i have with the HD 25-1 II.
Day two. Sleeping well, doing other stuff, going back to my headphones, turn on the music. Same repertoire as yesterday. - There is a difference already. there is actually a soundstage there now, albeit small. they veil is disappearing and it doesn't sound that warm and muffled anymore. It is not neutral sound, but on the other hand, if I were to listen to a lot of classical, I wouldn't buy 'rock-speakers' anyways. I read reviews about how the phones were lacking in the upper levels, that sounds like -'S', -'SH', -'CH' etc would be... ...not perfect. Well, day two improved from day one in this aspect too.
The bass wasn't 'fluffy' anymore, but still deep. actually plenty deep, imo. and the midrange had improved a lot. from having to 'look' for it, to get it all the way to your ear without having to notice it was missing. Six hours, before they get uncomfy. -and after six hours, anyone will get tired in their heads/ears.
The headbands are not noticeable... ...and the cable is not in the way, nor noticeable.
Day three. Hah. Even better. After a total of 18 hours, the phones are now ready to be listened to.
You could say the virginity of it is now gone, and it is ready for some proper exercise and training.
I am not going to blast the volume on max for any reason, just so its said, but now i don't mind my equally critical friends to listen to them.
Day four. time to write a review.
I can only assume the sound in them will get better and better as time goes by.
The only, and ONLY thing that would make these better, were if the sound picture was wider and deeper.
It isn't a must, but it would be nice. After listening to High-end systems with SNELL speakers, more expensive than my pants can carry the cash, an open environment, -or the lack of it iin this case -will be burnt into your mind, and one will never be completely satisfied, unless buying super expensive stax with equally expensive amplifier(s), used on an equally expensive high end stereo setup.
 
These are lightweight, durable, good bass, good mid-range, good treble, even for sibilant music (Beware of Justin Bieber... ...the phones can't take that. The speakers will crack and fall into a hot,deep pit where beelzebub and his minions are removing impurities from the liquids in their forges.)
Seriously, the higher areas of music are just fine in these phones. -already by day three/four.
Every part can be exchanged.
If only the Amperior was cheaper, I'd go for that one. It is better, but kinda expensive if one doesn't have the money for it, you know what i say.
 
All in all. You can't go wrong with these ones. -unless you have extrordinaire music taste, are analythical instead of enjoying the music, like a nice glass of brewerage. I don't taste and spit the red wine. I drink it, and enjoy it for what its worth..

I'm pretty far from what I'd consider to be an audiophile.  I know that based on the extremes that people can go with this stuff that I'm never going to bring myself to justifying that kind of obsessive behavior, but I do believe in quality and performance and when you find something that works that the price is usually well worth it.  These headphones are the definition of money well spent.  I had bought blister pack junk in the $50-100 range for years with about every single year requiring replacement.  Not only did they not hold up, but they just never really sounded great.  I think that the sound quality has been discussed to death on these over the years as they are far from being a new product.  The only thing that I'll mention in that regard is that they are one of the most sensitive sets of headphones I've ever heard. When I was shopping for a "big boy" pair of cans I A/B'd every single headphone I could get my hands on and I discovered pretty early on that some of the higher end ones were going to require a dedicated headphone amp.  These do not.  I would be afraid to put an amp through these out of fear of blowing my ears out.  Portable, computers, etc., all drive these to insane volume levels with no problems and to me that means that their amps don't have to work as hard so I have less chance of distortion from overdriving the circuit. 
 
Perhaps I'm mistaken, but it makes sense to me.
 
The reason why I'm posting this "review" is because I recently replaced the cord on mine.  Now it wasn't that it wasn't working any longer, but I wanted a coily one so that I wouldn't be running over it with my chair anymore and I came across this place in my online search for a replacement.  It's funny because this was the place that I found when I was shopping for them the first time.  I thought that it would be cool to do a ten year trial period review. 
 
I've had to replace the earpads once.  I've replaced the cord with a coily copper one from Sennheiser.  Now I don't get all wrapped up in the oxygen free depleted uranium titanium shielded kevlar cable stuff, but I did notice a marked difference in sound quality.  Not massive, but noticeable.  While I'm sure some will argue that is because of the copper I honestly chalk it up to the fact that the other cable had been run over about 2 million times in the last decade by a chair containing my large backside.  I'd like to see how well you performed after that kind of abuse.  The fact that it still worked in the first place is amazing to be honest.
 
I'm not an occasional headphone user either.  I'd say that over the course of a month there is probably about 3 days in there that I don't use them.  I have never had a second's worth of problems with them in that time. 
 
Some people may not like the way they sound.  I love them, but everyone's taste is different.  But I don't think that I've ever owned anything as reliable and if you calculate the money that I spent on headphones prior to buying these I would have saved a few bucks if I had just bought these in the first place.  If you figure out the cost of replacing $50 clunkers over a ten year period it's not even worth considering.  I've not only enjoyed outstanding performance the last decade, but I've actually come out about $250 ahead in savings on garbage.  Subtract about $100 for replacement parts (pads and cable) and I still have $150 leftover and a pair of headphones that are still working as well as they did when I bought them ten years ago.  I don't think that I even have anything in my house that's ten years old anymore (besides my kid and his days are numbered). 
 
One of the best investments in anything I've ever made and I can't recommend them highly enough.

Haven't had these for very long but impressed upon initial listening!

The problem with having a reference-grade pair of headphones for home listening (in my case, Grado's amazing Prestige Series SR325is) is that when you start looking for 'phones to listen to away from home, just about everything you try inevitably comes up short in one way or another, and the name of the game becomes "which set of compromises am I willing to live with?"

For me, the current crop of headphones aimed toward portable listening is, at best, merely acceptable. I could drag out the usual suspects to use as punching bags, but we already know who they are; just think style-over-substance and there's no need to name names. But there are a few seriously-mediocre 'phones out there offered by outfits that should definitely know better (AKG, I'm looking at you). Really, nothing I listened to in the "portable headphones" category did the trick, which is rather astounding given the money being asked for some of the upper-end models.

Then, while grousing about this situation to a sales guy at the headphone counter at J & R the other night, I got a suggestion I should have thought of before: ignore the "portable" category altogether, and audition something a pro would use. However, one good reason why I hadn't thought of this is that most "serious" headphones also typically sport some serious size and weight, and aren't always something that's easy for something like an iPod to drive at satisfying (not ear-splitting) sound levels. Yes, wearing big 'phones on the street is apparently cool again, but I prefer being a bit more discreet in my headwear, although I'm about done with in-ear phones and their assorted anomalies.

The sales guy then handed me a pair of these Sennheisers. I listened. I looked them over. I listened again. I was sold, simple as that.

They're decidedly ordinary-looking, literally dull. Sennheiser didn't exactly go out of their way to make an unstylish headphone: this is a model that was pitched initially to people who care a lot more about a 'phone's performance and reliability/durability than about how cool they look (or think they look) while wearing them: recording engineers and producers, sound-reinforcement people for the stage and the screen, sportscasters, and, of course, DJs. Think of the '55 Chevy James Taylor and Dennis Wilson drove in Two-Lane Blacktop: not slick, not working too hard to be cool, but clearly having what it takes to do the job.

And, what a job! Riding the train or bus, or walking the streets, I get the music, full, deep and wide...or not, depending on the recording. Being more of a true "monitor" headphone, the HD 25 doesn't do much in the way of juicing or monkeying around with the signal in the name of making a grand impression; if the recording is good, you'll hear just how good it is, perhaps for the very first time while away from your "reference" home 'fi. If the recording is sub-par, you'll know that, too, but the result won't necessarily be unlistenable, just minus any sugarcoating.

A few have pointed out the HD 25's nearly all-plastic construction, regarding it as "cheap." There's nothing cheap about this headphone's materials or construction: having been on the market for well over a decade, its design and build quality have been proven countless times in the professional field, where people are not known for treating gear with kid gloves. In the hands of the average consumer, these cans will easily outlast any flavor-of-the-month style-phones by an order of magnitude.

As durable as these are, they're also a damn sight lighter than your typical please-don't-drop-me bling-phones. I won't say it feels like you're wearing nothing on your head, just that it's a light touch overall. For some people, however, the pressure of the headband's "clamping" effect might be a bit much for listening much beyond an hour; this gradually eases as the headphones are broken in.

And, speaking of "broken": if by some freak event you manage to do damage to any part of the HD 25, that broken part can be replaced; Sennheiser keeps an inventory of spares if needed.

(As an aside, these headphones happen to be manufactured in Ireland. Take away what you will about that.)

That's the picture for you. I love the things. I think there's a fair chance that you'll at least like them.
 

Old timer which is still the best.
I love its dynamic sound but can brings fatigue after some hours.
Every things is there :bass, mids & highs with good details.
Every parts can be changed to make sure it will last long,
The only complaints I have : it doesn't fold 
 
I think it is still the best on-the-go headphones
 

I bought these puppies just before Christmas and they have been a revelation.
 
I can't tell you how much they suit my listening tastes. I love close listening with lots of treble and tight bass and these deliver this in abundance.
 
Never before have I been this sad to take a pair of headphones off.
 
I used these for traveling to work but have been using them more and more inside as my main headphone. I can appreciate that the sound may not be for everyone (no sound is) but if it is then, sweet baby Buddha are you in for a treat.
 
The build quality is exceptional and the anti urban styling spot on. I even (unlike most) like the pleather comfort!
 
I can't see me replacing them anytime soon.
