Just picked a pair of these up off another head-fier.
Must say that I am incredibly impressed. I had high expectations and these exceeded them.
I wont repeat what most people have already said, the sound is phenomenal. The bass is ideal. I listen to a lot of rap although I have a very eclectic taste in music. While I enjoy rap, I have been jamming out to David Gilmour's Live in Gdansk, and it is euphoric. These can's deliver on sound in a big way.
As for things aside from sound that I can speak to:
I have a big head, hard to find a hat actually.I also have larger than normal ears. As I read countless reviews for these, everyone said the same disclaimer of "if you have larger than small/average ears, these might not work". I have a larger than average sized dome and larger than average sized ears. These things do no totally encompass every part of my ear, however that is not a knock on them. Their ear pads are very well designed, and as a result complete a fantastic seal. There is next to zero leakage all the way up to 75% of my volume. I generally listen at around 50%. On the flip-side, these phones isolate great, even if it isn't the "ideal" fit for my ears. When I first got these, I immediately put them on and started listening to them. During this process, I had accidentally jacked up the sound on my home TV with surround sound. I was sitting there listening to some Tool when my wife got home wondering why the TV was up so loud. I was jamming out on the cans, and I didn't hear the TV at all, which was on relative blast right in front of me.
Seriously, there are just something about these things that are incredibly comfortable. They have been ontop of my head for at least the last 6 hrs straight. Had to take them off a few times and what not for a minute here and there, but I barely feel them. The only sign of "fatigue" or "discomfort" from these headphones comes from the fact I wear glasses, and these do a better job than most in that regard.
The chord with mic works partially with my android (Note 2 and Note 3, also tested on s4). I can answer and end calls, as well as pause and stop the music. The only things I cannot do are use the directional buttons for skipping or forward. The mic is fantastic, as everyone I have talked to says that it sounds like I am talking through my handset. The other one is just a standard chord.
Sound: 9.5/10 (Best headphone I've heard for all around music, I deduct half a point, because clearly there are phones out there that will get that last 5% of the sound out of the music)
Fit: 9/10 (Not a perfect over the ear, as they don't fully encompass, but they do isolate better than most and they sound and feel terrific as a result)
Comfort: 10/10 (Most comfortable pair of Can's I've owned in my life)
