Pros: Crisp, Clear, Detailed, Neutral, Amazing soundstage
Cons: Bass is light, Price
I recently spent about a month with a pair of HD800s. I was immediately more impressed with these upon my first listen than with any pair of headphones ever. The amound of detail these present is just unreal. The sound is VERY neutral, true to the recording, and because of this bass can seem a bit lacking. To be honest, even with bass-heavy music these are a bit lacking. However they have the fastest, most detailed response I have ever heard from a pair of headphones. Midrange and highs are the best I have ever heard on any headphone without a doubt. Soundstage is quite expansive, they sound very "open" and airy with outstanding clarity. They are hands down the most comfortable headphones I have ever worn. My one complaint with the design is how easily the paint chips, as many have said before. They are expensive, and I while I feel that they beat my LCD-2's in every single way possible I still prefer my D7000s to these. I guess it just comes down to personal taste. If you like a robust bass response like I will admit I do, these won't be for you.
