Latest reviews

Pros: Comfort, Solid feel, Amazing bass, Good mids and highs, Excellent cable, Very soft pads, Decent isolation, Very good soundstage
Cons: Not neutral, Could sound a bit too dark for some genres... mids & highs could be improved, not portable or for outside use
I have got these recently and was surprised by their quality and solid feel. They quite heavy too but definitely not too heavy. They fit nicely and they are very comfortable mostly due to great extra soft pads. They also isolate pretty well but they could do better.

Carry bag they come with is very solid with very thick texture, rubber material from inside, it will last forever. Comes with two cable one for mobile use = nothing extra and the second one for home use very decent and pretty thick cable, quite long as well about 2m. Connectors are great quality too. Very happy with their look and feel... I did not expect them to be so good.

They might be a bit too big for some people and these are definitely not portable. They are easily driven according the paper but I have only tested them with proper Denon amp PMA-720AE. Sound quality overall is excellent. They have this great Denon signature sound which is warm with pretty neutral highs and mids and slightly overpowering bass but only to make them more enjoyable. I did definitely enjoyed every minute of listening these trying various genres these HAS NOT failed me once. All genres were pleasure and fun to listen. Where these excel is electronic music, 80s synthesizers, 90s dance, techno, etc. Also soundtracks form movies like Inception, interstellar, predator made me love these. Another nice experience was listen to high quality jazz music and surprisingly again these managed to reproduce the instruments very natural and realistic with great amount of soft pleasure to listen to bass emphasis. The song I enjoyed at most with these was the Queen Radio Ga Ga (FLAC).... I almost cried listening to this song with D600, it was just EPIC.

These headphones are further excellent for movies and gaming. When I played Outlast 2 for example they added a different level to the overall experience. I strongly recommend these for long listening sessions as they do not make you tired at all. Can't think of any better headphones for movies and gaming as headphones with such strong / good bass always sacrifice the mids and highs for that purpose. Somehow these D600 don't. Yes, they are slightly darker than other good cans out there and they could do more with better highs and mids. You would not notice this until you compare them directly with other cans then you know the highs could be crisper and mids more forward. I heard from different sources that this issue improves rapidly with some extensive burning procedure. You need to burn these for hours to get the best out of them and I cannot wait to get to this stage. Since few days of proper burning I definitely could hear the improvement.

Note that these cans might be not the right ones if you are for flat or as much natural sound as possible. If you are looking for professional monitor cans with better detail and isolation you might look elsewhere. If you are about great sounding bass with very good overall sound quality plus the fun factor of listening to pretty much anything then these are the right ones for you.

I got these for only 130 pounds here in UK including extra solid case for them and I am super happy about this purchase. I wish I could compare them to the D7100 and to find out what is the buzz all about but my next aim are the D7200 ones. I will post the full comparison of these for sure. If you curious about the direct comparison to MM400 and HP800 then check this link you might found the results surprising:

Forgot to mention the soundstage which I like a lot. They sound just the right size not too much in your ear but also not too far from the source... well done. I personally think these are quite underrated and people many times don't test them with proper amp and source. If you tried them for longer you fall in love.


Just want to add that after lot of hours of listening and also some additional burning in these sounds fantastic. The mids and highs opened and they are more forward now which is exactly what these cans needed. Excellent headphones for the price and great headphones for overall genres, movies and gaming.
Pros: Bassy, deep & wide soundstage, comfortable, come with high quality cables, easy to drive.
Cons: Huge, look ridiculous, not very natural tonality
A great purchase for under 180 pounds, these headphones blow the direct competition away when it comes to almost everything.
They arrive in a nice premium package with a thick, high grade cable for home usage and a smaller one with microphone for portable usage. They are very large and do look a bit incongruous in public, but they are clearly well made from premium materials, sturdy and not too heavy. They are very comfortable, with thick earpads and the weight is evenly distributed towards the sides of the head.
They have a very low impedance so can be powered to uncomfortable volumes even with a portable source, though as ever a powerful amp improves fidelity. The sound of these 50mm driver packing headphones is not particularly natural but is certainly fun.
In terms of frequency response, they are bassy and perhaps a little boomy not to an uncontrolled degree , they rarely distort or gets in the way of the midrange and highs, which are clear, and present if a little on the metallic side. If the bass level seems too much, this can be rectified with gentle equalization. The sound-stage on these is fantastic, almost as good as an open backed headphone, with plenty of width, depth and precision. They are slightly on the "relaxed" side for an audiophile set, in terms of attack and decay but should be fast enough for most genre's of music to come over with purity.
All in all a very worthwhile purchase. It's a shame they are no longer easily available.
Pros: Easy to drive, Tight and controlled bass. Very soft ear pads though can get hot over time. Nice soundstage.
Cons: Tooooo big. Sibilant. Mids are slightly recessed. Very "V" shaped.
So I got this headphones used on Amazon for €170 which I think is a pretty good deal. I mostly listen to alternative metal and rock. ( Korn, Deftones, Radiohead, System of a Down, etc.. )
Screams Premium. Nice box with soft clothing, two cables ( iPod compatible and a 3m long OFC cable ) and a decent carry case. 
Build Quality:
Looks a bit like the beats from the side. But it is very big and heavy (sorry smallheads). The ear cups are very soft but can get hot after long use.
Sound Quality:
These headphones are really good at the first listen when directly compared with the HD600s since it has a heavier bass (controlled and tight, which doesn't bleed into the mids) 
Spend more time of with these I find that the mids are slightly recessed (lacking in detail).. not really too much but it is simply not comparable to HD600s (of course these are not mid centric phones)
The treble is not too much that it might get fatiguing but it is in the right proportion. It is also sibilant on many recordings I tested.
A very decent soundstage for a closed back. Almost similar to the HD600s. 
Though these are 32ohms and can be driven by phones and iPods. I tried to use it on my Marantz HD DAC1 and it sounded a bit better/fuller.
Maybe my ears are tuned to HD600s and so these sound harsh to me both on the bass and treble side. But it does not mean these are bad headphones but I simply think these are not worth the premium price for the new ones. Find good used ones and you wont regret it.
