I received the HD700 today. Thank you so much Justin for putting together this program where we can try out these headphones with our own gear at home. I've been telling friends/coworkers about the headphones and your program and they are just amazed that somebody would do that.
When I opened the well-packed package I was very impressed with the condition of the headphones. Not only did I not see any marks/dings on the headphones themselves, but even if the earpads looked brand new. I posted a few cameraphone pictures below.
They HD700 are extremely comfortable on my head. I am surprised that they might actually be more comfortable than my also very comfortable HD650. I definitely like the cord better on the HD700 as it seems to have longer cords between the L/R headphone entry and the V split. I've also had no issues with wearing glasses the entire time I've word the headphones.
Initially, I listened on an Audioengine D1 that I had at work. It sounded nice. For the most part, I thought the headphones were a little bit mello. . .but the treble did kick up a bit on some tracks. It didn't bother me as much as the treble HE-400...but I don't have those any more to compare side by side.
When I got home, I listened to some FLAC files on my Uber Bifrost/Lyr combo. I think the soundstage was a little bigger. . .but it might just be the different tracks I listened to or my imagination. The sound is very pleasing with the exception of the occasional times the treble gets to be a little too much. I can see where some people might find them a little light in the bass but I don't have a problem with it at all. It does seem to snap a bit tighter than the bass in other headphones. Can't wait to listen to some more.
