I received my pair earlier in the day. I definitely see what people are talking about regarding engagement. Everything is very present and full and the macrodynamics are the best I've heard on a pair of headphones. Unfortunately it looks like I've run into a slight problem, and I'd love some input. After listening to them all day, I can't shake the idea that these sound darker than they should. I know that they have a certain amount of treble roll-off and that the mids are dominating, generally speaking, but the treble seems recessed, which is strange given that many people have called these bright headphones.
I think the culprit is probably the deteriorating pads that it came with (which are really kind of gross - greasy, with the coating on the bottom part sloughing off - but I knew they would be like this). The sound of the headphones right now is very dependent on how they're positioned on my head, and pulling them away from my ear just barely enough to break the seal is enough to make the headphones sound much more open. Does it seem like I'm likely right about the pads, or is a recessed treble something others have noticed with these cans even with pads in good condition? If these replacement pads don't work to open up the sound a tiny bit, I may try to get one that's a bit thicker, just to get a little more air into the sound. And I'm not looking for a drastic change - they just seem a little dark, given what I was expecting. While I do like my bright headphones, I doubt this is just me - even my Sextetts sound brighter than the AD2000s as of right now.
