    "Awesome bass"
    This set is my first. I was looking for something that would be good with bass, wasn't as wholly picky about other requirements since, to be honest, I didn't really know what I was looking for at the time. Formerly all I'd used were earbuds you could pick up at a corner store for five bucks and a $20 Microsoft set, hardly the headsets of champions. But this certainly exceeded expectations, although I will say the first day or two of using it was underwhelming - I was completely disappointed when I first put them on but decided to keep them until I'd had a bit of an adjustment period, and I'm glad I did.

    I found my set secondhand, in the colour white. It came with black DT770 velour pads and the side shields had been replaced with black carbon fibre ones, giving it a fairly nice Stormtrooper sort of look. It also came with a V-MODA mic but I haven't used that, so no comment there. Otherwise they're pretty much what comes out of the box. As this is my first set, I will say that I don't really know the proper terms to describe what I heard out of the set, but I'll do my best. I used them with my cell phone on the bus and with my laptop at home.

    Build - This thing is so comfortable it's ridiculous. I really wasn't expecting it to feel so nice. It fits well over my glasses and I didn't really have to adjust the headband, although when I tilted my head back, it shifted just enough with my movement that I instinctively put my hand back to catch it (though it didn't fall off at all). Overall it felt the slightest tad heavy at first, though that disappeared once I got used to them. I noticed the clamping feel the first time I put them on, took them off for a minute, and put them back on again to feel nothing. They feel a like a set built sturdily enough that you don't have to worry about them getting banged around every so often.

    Appearance - I feel like the logo (in two places) was really subtle, enough so that I actually missed one of them the first time I looked it over. The shields aren't the ones the set comes with, but they're high quality and have a nice feel to them. I have a white headband on mine, and I will say that the headband picked up some discoloration on the lefthand side, though that's probably just because I have dyed hair. It has left and right sides marked on the inside of the headband, and "Made in Germany" on each side.

    Phone - Bass one the first song was nothing to write home about. Although I will say that it wasn't a bass-heavy song I was listening to, I didn't really notice a difference between the four bass settings, and it was honestly fairly comparable to my former cheap set. First song I listened to was a music video that had some sound effects in the beginning, and the set picked them up pretty well, so I'll give it that on its first run. The soundstage kicked in on the song after that, although to be honest I had already sort of written off the set and wasn't exactly listening for anything special. On other vocal songs, the soundstage was really good in my opinion, it had that kind of feeling like you were wearing a sound bubble around your head instead of getting sound from both sides of your head. One had an interesting effect to it - it sounded like the sound was coming from the middle of my head and then started bleeding into the fishbowl soundstage effect.

    Bus - Still no bass from the phone but very nice ingoing noise isolation. Blocked out the bus' automated announcements, people talking that were more than a few seats away, and most of the engine rumble. The cord it came with is too long for walking, and the set's a little bulky for walking around, but a shorter cord would make it perfectly acceptable for me. A buddy of mine said he didn't hear any outgoing noise

    Computer - Did way better with bass overall. I listened some songs again and got a better opinion of things, and picked up a few minor sound effects that I hadn't known were in the video. The soundstage for a Bon Jovi song actually caught me off guard because I just wasn't expecting it to have a distinguishable effect. I was actually quite surprised by how well the set picked up the higher notes for some rock songs, especially with the bass displayed at the same time. I actually heard background vocals and echoes that I hadn't known were in one song, though the sound in general came off as kind of muddy.

    Overall - After a couple days of leaving the set on high volume, it really started to shine, and I couldn't ask for better. The set is amazingly comfortable, although I believe the stock pleather ear pads would have been less comfortable, even if that's just my taste. I will say that the ear cups can get the tiniest bit overheated if it's really hot outside. Honestly, I really love the set, it did better than I thought it would have even with the good reviews I read. Not gonna lie, I listened to some of my favourite bass-heavy songs and fangirled. Wouldn't drive it from a phone if I wanted to get any bass at all, but from a laptop, it works really well.

    "Damn Awesome"
    Pros - Quality in this prize category is awesome, Good for bassists if they need to hear a faint bassline, Extremely durable headband.
    Cons - The original pads hurt and make ears sweat, Their original cable was very weak.
    I personally thought these were a lame purchase after i had bought 'em. About a week later i just left my apartment and left them shouting out opeth and other metal with the bass in 4/4 position and the volume in 60% for the whole 48 hour weekend and immediately i could hear the bass even in the bass poorest position.
     
    I mainly listen to prog rock, metal. For those genres these have proven optimal but classical has a certain deepness in it too.
    In fact after giving these a good 50 hours (or more) of bloodbath was a good thing to do. Now even 2/4 of the bass sounds too much.
    These are pretty perfect headphones in this prize category (at least for non-classical enthusiasts) and are extremely durable.
     
    They are comfortably tight on ears and sound isolation works well.
     
     
     
    - I am using these with the velour pads of Beyerdynamic Dt660 phones. Others have complained that the original pads make these uncomfortable but this completely fixes that problem.

    "Comfortable "
    Pros - comfortable, easy listening, headset option
    Cons - Lack of tightness and fine details
    Pros:
    - Comfort (well built and padded with light weight)
    - Effortless listen (good for background music and forgiving with bad recordings)
    - Over the average soundstage (compared to other closed backs)
    - Headset option for gamers
     
    Cons:
    - Lack of tightness and fine details (dull for my ears)
    - Overpriced if you look at the SQ only

    "Not For Vocal Lovers"
    Pros - CUSTOMIZABLE SOUND, Comfort, Sound Quality
    Cons - Not portable AT ALL, Ears get hot, Almost no accessories, Vocals VERY reccessed
    TL;DR: Don't be lazy and read it all
     
    Hey guys, Zero Decibels here with a review of the Beyer COPs, I got these for about 158$ from a local store. As usual, I'll be judging these from 4 aspects; Design, Build Quality, Comfort, Sound Quality
     
    Design (4/5)
    Nice design, especially with all the customizable stuff. Has potential to be the most colourful headphones if done right. Then why does it only has 4/5? Because these things are HUGEEEEEE! These are so big that you'll look dumb just wearing them. Combine that with the fact that these doesn't fold flat or inwards makes these cans have 0 portability. Which is weird, considering these are supposed to be portable.
     
    Build Quality (5/5)
    Made in Germany. Nuff Said.
     
    Comfort (5/5)
    The only good thing about having gigantic earcups are having amazing comfort. The earcups are really spacious and deep, so any kind of ears could fit, big or small. The padding is also very nice. They get hot quickly though.
     
    Sound Quality (4.5/5)
    Gonna split it out into the 4 positions
     
    Position 1: Sounds anemic. Almost no bass at all, only a tiny bit of mid bass. Clear mids and treble, but no body cuz of the lacking bass. This position IMO, is the worst among all 4.
    Position 2: More bass then pos. 1, but still lacks sub-bass. Better sounding overall, and great mids and treble.
    Position 3: Pos.2+sub-bass=Pos.3. My favorite overall.
    Position 4: Only bassheads need to apply. HEAD SHAKING BASS, but because of the huge bass, it slightly bleeds into the lower mids, making vocals EVEN MORE reccessed then before.
     
    Overall Sound: Very reccessed vocals, but great instruments. Great detail for its price, and AWESOME BASS (cept for pos.1). Not for vocal lovers since the vocals are recessed. GREAT ISOLATION, best I've heard in a circumaaural. Awesome for EDM. Could sound artificial at times so not really the best choice for classical lovers, but for people like me who love EDM, mainstream pop, and rock, these are really good.
     
    Misc: Only comes with a cable and an adaptor, no other accessories. 
     
    Well that's about it, thx for reading!

    "Compromised but FUN!"
    Pros - Very versatile, top notch SQ
    Cons - Comfort, Ergonomics, Aesthetics
    I'm relatively new to the scene and my wallet's already hurting! I've read posts on here for months so I think it's finally time I contribute something. This will be my first review, so let me know what you all think :)
     
    I'm going to write this review assuming you've read the less detailed "overview" reviews and that you're familiar with the ins and outs of the product/packaging, etc.
    These cans have burned in thus far playing a random mix on iTunes for 48 hours straight. I will try to update this after a few months once these have over 200+ hours of burn in time.
     
    My taste in music
    Fairly diverse! Currently jamming to the Above and Beyond Acoustic album. Earlier I listened to Nero's Welcome REALiTY album, The Roots, The Naked & Famous, Junip, Beethoven, Einaudi and Eric Prydz. Pretty much everything except for pop and country. Of course my reaction to these cans is completely subjective, but if you have similar taste in music, hopefully my observations have some applicability.
     
    Source audio
    All uncompressed FLAC or m4a files. 
     
    Power Management
    Between my Moto x (having a tough time powering them - a constant feature with this phone is that it's up at 80% volume), my old HTC One X [designated mp3 player] (50% before hearing damage would ensue) and my Macbook Pro (~50-60% volume without EQ'ing), I'm never left wanting for volume. I tried using the Fiio E11 with all of these applications but it really wasn't necessary. I've also had the COP's plugged into a PS4 controller playing BF4 for those who are interested. The headphones work VERY well with the bass ports fully opened - tanks and choppers sound unreal and there's a satisfying "whump" every time a shot is fired. These are also great at indicating where shots and footsteps are coming from. Perhaps not as good as audiophile grade open back headphones but nevertheless impressive. A for gaming! With that said, I would definitely recommend using an amp for this application as the PS4 controller's is quite weak.
     
    Aesthetics/Ergonomics - 6/10
    Let's get this out of the way. Design-wise, I think these headphones are pretty ugly. I know this is completely subjective, and there it is.
    I will most likely never use these headphones outside my home. They are simply far too cumbersome. The cable is too long for mobile listening (I'm 5'11). They don't come with a carrying case of any sort, which is fine given that they won't be moving around much. I have a relatively small head but these things literally double the horizontal footprint of my head. I can't put these on my neck and walk around because they don't fit in the space between my collarbone and my chin. Far too big to be considered portable. Granted, these are not designed to go everywhere with you, but there is still so much to like here. 
     
    Build Quality - 9/10
    These things are German. Beyerdynamic made it a point to slap "Made in Germany" on the inside of the headband. They're built like tanks - everything about them is heavy. The cans feel heavy on my head. The plastic rings that hold the custom side plates in place are held in place by 4 (yes, 4) exquisitely machined micro bolts. The removable side plate is made of brushed aluminum. The cable (removable) is heavy. Tangling is a non-issue and the cables do not lock in place (unlike the Sennheiser Momentum) which is a great safety feature IMHO. The headband adjustment clamps require a "heavy" push in both directions in order to move them. The sliding bass ports require a firm push and snap into place very satisfactorily. The clamping force on my ears, at least when I first got them was heavy (stretched them out as many others did using a pillow). This general heaviness can be likened to driving a manual car with a heavy gearbox and clutch - cumbersome but at the same time oh so satisfying. I feel as though these would stand up a 6 year old's level of abuse.
     
    Comfort - 7/10
    The ear-cup opening on these headphones is huge. My ears (medium-large) fit inside easily in their entirety. They aren't even touching the inside of the cups. Nevertheless, I need to take breaks because these COP's are pretty large/heavy and my ears do tend to warm up after extended use. Still, there has been zero pain or discomfort to speak of because my ears are for the most part free  moving. Also I can't turn my head at any angle when resting on a pillow listening to these headphones. From time to time I also rotate the headband to the back of my neck after extended listening. 
    Yes, these are first world problems. 
     
     
    Sound Leakage/Isolation - 10/10
    The headphones really shine in this regard - even at low volumes the isolation is excellent and there is very little leakage unless the cans are amped up to very unsafe levels. They're like sitting in a black box with your music. Excellent.
     
    Sound Quality - 9/10
    Man what a difference burn in made! Out of the box these had a very dark sound with very recessed mids. Now that the drivers have loosened up a bit the mids have really filled out and the sound is much warmer.  These headphones are quite forgiving when it comes to exposing weaknesses in low quality tracks. I'm not entirely sure why, because I can still certainly hear clear, detailed sound with uncompressed files. 
     
     
     
    Soundstage
    Not all that impressive, but I will reserve judgment here until I have a good pair of open back headphones against which to make a comparison. These aren't as clear as some headphones because of the emphasis on bass, however with that said the bass doesn't drown out the other sounds either.
     
    Bass
    These headphones pound. Beyerdynamic makes no bones about catering to bassheads with this product. In terms of sheer bass quantity, these produce a warm, rich, punchy wall of low end goodness. The bass does get overwhelming with the bass ports fully open at times (I primarily use them to emphasize punch for EDM), but I cannot describe how convenient it is to just close them on the fly. At first, I thought the bass and mids were very muddy (think first gen V-Moda Crossfade LP but nowhere near as bad). However, once burned in, the bass became tight, crisp and clean. 
    When the bass notes stop (even with the ports fully open) in the song, there is no residual muddiness - these headphones have sharp reflexes and have proven to be quite versatile when it comes to tolerating demanding songs like . Everything sounds exactly as it should be.
     
    It's worth noting that these headphones are BASS heavy when the bass ports are opened, and at first I did notice that with the bass slider set to "least" bass the low/mids sounded a bit strained but adequate burn in alleviated that. 
     
    These are the bass port settings that I gravitated toward during my testing:
    Electro/House/Dubstep - Varied from fully open bass ports to 1 click from fully open.
    Indie/Rock - Between 1 and 2 clicks from fully open
    Classical - 3 clicks from fully open
    Spoken Audiobooks - Between 2 and 3 clicks from fully open.
     

    Mids
    At first the lower registers were jumping all over the low/mids to the point where male vocalists sounded like they were singing into a garbled microphone through a tube from a different room. That has all changed now that everything has been broken in. Please forgive my n3wbiness here but it sounds as though the burn in period allowed for adequate separation of the bass from the mids. The mids seem to be much more flexible and present as compared to when they came out of the box. At this point, both the male and female vocalists on Above and Beyond's "Satellite/Stealing Time" acoustic mix sounded amazing. At first it sounded as though the male singer was singing at half volume compared to the female. 
     
     
    Highs
    Out of the box this is where I think the COP's struggle slightly - perhaps this is the last bit of the puzzle that needs to be unlocked by yet more burning in or amping/EQ'ing appropriately? I tend to favour headphones that have a brighter overall sound with good representation of uppers/highs. These headphones responded admirably to EQ'ing, regardless of the device being used. Nevertheless, this represents a compromise and despite how natural the Instruments now sound, there are better headphones for representing upper mids/highs out there. Still, despite the general emphasis on "fun," the V-shaped sound signature and the general quality of the bass reproduction, the rest of the sound will not suffer as it does in other headphones (again, sorry to pick on the First gen Crossfade LP's, but they were atrocious for this very problem).
     
    Conclusion - Overall 8/10
    The real selling features of this headphone are as follows: 1) Non-gimmicky customizable bass ports, 2) A very compelling compromise between a "fun" and an "audiophile" level headphone from a company that is well established in both realms. 
     
    Has this worked? Yes, indeed.
    I find myself EQ'ing on the fly with the bass ports every time I switch between genres, even between different maps on Battlefield - it makes that much of a difference and it makes listening to music effortless especially when multitasking. For those of us who like to tinker (we all do - who are we kidding) this is soooooo much fun! While I'm sure there are better headphones out there, these will keep me happy for quite some time. They're versatile enough to give me a sense of awe when I'm listening to music, and it's very difficult to quantify that. 
     
    Happy listening everyone! :)

    "Good not Great"
    Pros - Heavy duty construction, adjustable bass ports, stealthy looks, decent sound
    Cons - Clamp, price
    Out of the box, these guys are impressive. Killer looks, minimal packaging, obvious sturdy construction - in other words, German. 
     
    The sound was very good. They're easier to drive than most Beyer over-ears and they have a very good sound. I wouldn't say great. Coming out of my iPod Classic, the wider-than-average soundstage provided some excellent space for my live rock recordings. The bass was solid and got even better with my Fiio E5 - I imagine a heftier amp would do even better. The mids are so-so, not recessed in my ears but definitely not forward. The trebles were lacking, but they probably aren't supposed to be audiophile quality for the market these are targeted at anyway.
     
    Overall I like the COPs, although the ~$200 price tag may be hard to justify for some. I got a great deal so they were worth it. I think a comparable sound for cheaper would be the M50s.
     
    Hope this helps!

    "Man was I ever disappointed with a headphone."
    Pros - detail. minimal leakage, soundstage
    Cons - hollow, bass sucks, looks sturdy but not. could keep going
    I need to try and be fair with these headphones. but its hard with such a disappointing experience.
     
    Pros:
    pretty detailed
    minimal leakage!
    bass adjustment is not a gimmick
    bass quantity
     
     
     
    Cons:
    hollow sound
    mids recessed 
    bass is loose with no real presence
    pads feel uncomfortable(easy fix)
    distorts at high volumes
     
    Summary:
    I could get by if the bass was present and sounded a little hollow because it would fill up the sound a little. But I have heard other Beyers and recorded with the dt 770 and cant remember the bass being that flabby. Flabby bass plus V shaped hollow sound and harsh sibilance=wack. Its like its there but it's not ...so weird. I have never heard a headphone do that. The four positions are cool to have and a great thing to have but for me I would much rather prefer one that didnt have it and just did it right to begin with. Position 1 is absolutely useless, sounding so thin and horrible that you can't even understand who would use it. They should have left it at three and made it more present. 4 is loud but Its hard to explain a bass that is loud but not really there. Its like some thing is missing. 
     
    At loud volumes they rattle and do all sorts of weird things. These definitely are not made for the modern <35 listener and can't even imagine them for someone over 35 because they are so sibilant and hurt my youthful ears. I blast my ears btw with other cans and love loud music (prob shouldn't) but when plugged into my my late version iMac they hurt my ears. I have never heard headphones do this. This may sound stupid and trust me I am no beats advocate but I would actually recommend those over these. You would lose detail but these hurt my ears more than those for some reason. I would never buy either and hate even mentioning Beats. But wow what a disappointment. I lost my hdj2000 headphones and was hoping to get something to reach lower. But the hdj 2000 blow these away, though the COPS do reach a little lower. But its like it reached down into the well of bass and grabbed mud instead of water.
     
     
    Update: 2016 ... dang these suck... horrible headphones... heard em again and was like.... wow these suck.... lol  Read my review again and was like... dang I sucked lol.

    "Slightly dull, lack warmth and excitement."
    Pros - cant think of any
    Cons - uncomfortable
    Dont get why people are so excited about the ability to change the bass with the switches on the cups...for one you have to do it to both ears and they are very hard to move. if you have an amp/dac controling the bass that way is a better option for your headphone. These things totally dug in to my jaw.....put pressure on the eustachian tubes. The bass is totally untextured and sterile. Yes the bass is prominant but not in an enjoyable way. There was no sound stage or distinction. Sure, they are affordable but they'll damage your ears for sure.

    "An uneven but interesting headphone, which needs a long burn in to get the best from them"
    Pros - Decent sound (improved with velour pads), Ok bass (when set between 2-3)
    Cons - Very long burn in time, Not portable, didn't like pleather pads, mids slightly to recressed,
    From what I have read the COP's there has been a very mixed reaction to the headphones, some love them and some detest them.  I have had these headphones for around two year.  So here are my impressions and views.

    I am not going to get into the unboxing of these headphones, the packaging is ok but nothing special.  Really you don't get much with these headphone in the box.  Just an instruction manual, 3.5mm detachable cable and an allen key.  There are lots of other attachments that you can buy separately with more being released.

    Design and Practicality

    The look of the COP's is meant to be one of the headphones selling points and they do have a distinctive look about them.  The are not the best looking headphone but with the customisable plates and pads they can be made to look quite stylish.  Beyerdynamic have released the COP's in several colours and my guess would be that they are trying to tempt the fashion headphone listening into buying something with a little more sound credibility.  

    I am not convinced by the design of the COP's though, mainly because of practicality.  When you buy a set of fashion headphones like the COP's, I would say one of the aims of the headphone is to get notice when out and about and whilst, anyone wearing them will get noticed, they are completely impractical for travelling.  The main problem is the size of the headphone.  They are great for wearing on head but because of their size, they feel horrible around the neck, like wearing a neck brace and they are not the best headphones for carrying around in a bag.  Also because of their closed back design and pleather pads, they get extremely warm.  I walked around wearing them around London in November and sweated buckets.  They just got too warm to be comfortable.  So I am not sure that these headphones are a practical fashion headphone.

    Maybe the most interesting area is the bass slider, which has 4 settings in theory though I often use the slider in between settings (I will go into more detail about the bass and the effect the slider has, later in the review).

    Comfort

    As I said above the COP's with the pleather pad does get exceptionally warm, even when listening to the headphones at home, my ears got hot.  The headphone also clamps to the head quite tightly, and there was pressure placed on one area.  The metal in the headband is stretchable though and by flexing the headphones, it will loosen the clamping pressure.  The COP's can be fitted with the velour pads from the DT770 and this does make a dramatic difference, whilst there is still heat build up, it is much more manageable.  The velour pads do take some time to soften though, to give decent comfort.

    Build quality

    The COP's are very well made,  The headband is made made from sprung steel and is flexable,  The headphones themselves are made from a tough plastic, which feels decent. the detachable back plate and ring, with holds it on is made from metal.  Everything feels secure and put together, properly.

    Cable and 3.5mm jack, Part 1

    One of the things I am not a missive fan of is the cable for the COP.  If is ok but I have a couple of problems with it, which I have split into too parts.  The first part is how the COP cable locks onto the headphone.  The lock is plastic ball a bit of plastic which inserts into a gap created in the plastic of the jack (image 1).  With removal of the jack the plastic around the gap does seem to  take a bit of a bashing.  It still works ok but isn't that practical.    It is possible to fit other headphone jacks (image 2) but they have to be quite slim due to the hole in the COP's headphone (see image 3)

    The M-80 jack fits into the headphone because of the plastics thin size.

    Being positive for a second I haven't had any knots on the cable at all and the cable is a decent length for listening to MP3 plaers in pockets.

    Sound isolation and sound leakage

    One of the the stand out areas of the COP is the sound isolation and lack of sound leakage.  The closed back design is a massive advantage with the COP when it comes to passive noise isolation and I was really impress with the headphone, this was one of the areas where I think the pleather pad did slightly better then the velour though the difference isn't large.  Again the same can be said when talking about sound leakage, which is very good.

    Sound

    I think the biggest contention with the COP's has been with the sound.  Some have hated the sound, whilst others like it.  I would say that the sound from the COP's is not the most detailed but it isn't bad, when the headphone is set up right.  

    When I first got the headphones, I hated the sound.  It was just horrible and I even put them back into the box and was thinking of shipping them back.  Fortunately I decided to give them a decent burn in and this makes a dramatic difference.  The COP's really do need a long burn in.  Even after two and a half months I would say that the sound is changing.   It took about 12 hours before I even began to think that the sound was ok and much much longer to start to enjoy the sound.  40-60 hours and the soundstage started to open up and now it really is nice.

    Bass

    As said earlier in this review the sliders do make a dramatic difference to the sound.  There are 4 bass settings, with the bass gradually becoming more bassy as the slider is opened more.  Generally I would say that between 2 and 3 giving the best bass response.  I generally have the slider set at 2.5 or 3 which give a really good deep bassy sound, without distortion coming into the sound.  When the headphones are fully open the distortion becomes noticeable and the sound becomes more muddy.  I haven't found the bass to be that punchy, though it doesn't feel bloated either

    Mids

    The mids on the COP's have been the most frustrating part of the sound, and it has take a long time the mids to blossom.  When I first started listening to the COP's the mids where terrible and in particular the upper mids.  With a lot of listening though (100+ hours) the mids have come out much more and sound a long better, though they are a little recessed.  

    Highs

    I haven't had any problems with the highs.  To me they sound quite nice and I haven't found them to be too bright,  

    Cable and 3.5mm jack part 2

    The sound from the Bayerdynamic isn't great, after reading on the forum about someone changing cables, I thought I would try the same and used my M-80 cable to compare.  I have to say the M-80 cable does help, the sound is louder and too me, it helps with the mids a little (I could be wrong on this)

    Sound (continued)

    The sound from the COP's is very warm and I would would say that they are not a rounded headphone, audiofiles may want to take a pick axe to them.  For some music the COP's feel great but for other kinds of music, they feel out of their depth.  I listen to a lot of trance, big beat, rock and generally I would say that listening to these kind of music is nice (I am currently listening to Dark side of the moon, which is a joy).  I can't really recommend COP's for classical or pop, the mid's just doesn't have enough presence for me and I find it very hard to get excited at all.

    Conclusion

    The COP's are a very good headphone, with a great soundstage and generally good sound.  When buying them you have to take a bit of a leap of faith because they don't sound great to begin with, but with time you should be rewarded with a nice sound.  They are not perfect by any means, are completely impractical for wearing out and are a bit of an oddity, in the world of fashion headphones but they have character in abundance and if you listen to certain kinds of music are great fun.

    4.0/5,
    "Custom One Pro vs DT 770/80 "
    Pros - Very Portable, Comfortable, Great Value
    Cons - Bloated Bass, Forced highs
     
     

     
     
     

     
     
    Clearly I'm not a pro at this but here goes something... 
     
    After not feeling 100% satisfied with my T 70's I wanted a little more Umph in the bottom end so I found great deals on the DT 770/80 ($149 new eBay- Contact me if you want the link they have more plus a 60 day return policy... Yes 60 days no questions asked) and the COP ($189 Amazon-Currently you can get them for $162[​IMG]). I'm still not finished with the testing but so far I do agree with what some have said so far. The DT770/80's have a much crisper sound than the Custom One Pro's but thats not a knock against the COP which I like but it is what it is. I actually put them up against my HIFI-780's and the COP won hands down and I sold my 780's which again I loved.
     
    Now to the direct comparison and I'll break this down to make it simple and quick
     
    Comfort: Tie -  The COP's are super light weight, zero clamp, and soft leather pads while the 770's are a little heavier with a slight clamp but the Velour pads are amazingly comfortable. Not as comfortable as the DT 990/250's but honestly nothing I've ever worn before can compete with the comfort of those bad boys. I told my wife I was going to make a Velour jumpsuit out of those pads... She shook her head and quickly walked away. 
     
    Portability: COP - 16ohm speakers... Nuff said. You need to amp the 770's for them to reach their full potential but running them through my Macbook Pro I got great results. My e11 does ok but I think its time for a change but not sure what to change to, a little help would be nice for those of you that are amp savvy 
     
    Soundstage: DT 770/80 - This is where the tide changes and stays in favor of the 770's. The sound stage is amazing for a closed can and it has the best depth of any headphone I've tested/owned. Using them with my Astro Mixamp 5.8 is redonk!! The bass you would think would get in the way and yes its clearly there but it doesn't get in the way at all. Playing BF3 on my 360 good luck sneaking up on me because the distance and direction is better than the best "gaming" headsets I've tested. I'm a sneaky C4 junky so sitting and waiting for tanks has never been easier. And when the boom comes the bass is eye popping and always giggle inducing. Now on the other hand the COP are no slouches either, but the bass feels a little muddy and the separation is good but cant compete but honestly, what can?? 
     
    Highs: DT 770/80 - They just come through cleaner and more relaxed but neither has the it factor in this area. The COP's are brighter and seem to pop out a little better but at the same time can get fatiguing at higher volumes. While I was A/B the two this was the biggest difference IMO. The COP's highs are right in your face aggressive and at times it feels like they're trying to hard. That is where the 16ohm ratings are at a disadvantage because being that easy to run is nice an all until you wanna turn the volume up and it feels like your ear drums are gonna pop.
     
    Midrange: DT 770/80 - Not as recessed which will be shocking to most that know the 770's because they have pretty recessed mids in the first place but for the type of music I listen to with these they work. If I wanted to High and Mid myself to death I have the T 70's for that :) I think the real problem with the midrange on the COP's is the the fact the the highs and lows just simply overwhelm the mids and because the separation isn't that great it makes it hard for the mids to come through.
     
    Bass: DT 770/80 - This one I thought was going to be a toss up but it was not. At first when you pick up the COP's of course the first thing you want to do is crank the switch to the 4th and final position throw on some dub and get to work!! And at first its like yes this is nice, but once your ears stop ringing from all the Robot sex you start to listen and notice how bloated the bass is and how hard its working to keep up with the music you're putting through it. At higher volumes notes were missed, drops were sloppy, and general sadness started to kick in. Once the volume was returned to a normal state things improved greatly. Now the 770's on other hand were cool and collected regardless of what I put them through and at all volumes. The levels didn't increase with the volume and they remained steady throughout the entire process. What was funny was that the only time I felt they were limited was when I put them through my e11 hence the reason I say its time to move on. Soundstage was reduced and the bass got bloated regardless of the settings. Clear winner in the category.
     
    Isolation and sound leakage: Tie - Isolation goes to the 770's but The COP's do a better job at keeping all the sound in your head and not in your neighbors lap.
     
    Overall thats 4 wins for the DT 770/80's 1 win for the COP's and 2 ties giving the clear and decisive win to the 770's. I like what Beyer did here with the COP's. They clearly were going for the commercial sound and if compared to the Beats and Sol's of the world they win hands down in almost every way possible except for being overpriced. Beats will win that battle almost every time.
     
    Which one you buy is ultimately up to you and hopefully I gave you some useful information to make the choice a little easier and if I didn't oh well, at least I had fun in the process. Thanks for the read and please throw out your suggestions for a good portable Amp under $160 that will do a better job than the e11 or gives a different sound signature.
     
    Thanks again and Take Care
