Agree with eargasm and Dobrescu , futaki. The Signature DJ is just a more intoxicating listen, more vivid, more punch and pleasing bass than the 880s. However I also agree that during some situations the 880s are more comfortable and less prone to sweat build up than the Signature DJs very thick pads. The 880s are a lot less $ though and possibly might be a touch more value for money, but the DJ is the much better option for sound alone here... By the way I received my Edition 8s a few weeks ago and I absolutely love them. They seem to be more faithful to the recording while the DJ produces, maybe an overly rich sound at times than the artist intended. The Edition 8 also wins in terms of comfort and beat out the 880s and Djs in this regard on all fronts. They are very lightweight and easily portable. Come with a fantastic , very high quility leather transport bag. Though I like the DJs case almost as much, but not quite. I have sent my Signature DJs in for a hardwired split mod from Moon Audio (Black Dragon with Rhodium plug.) Then when I get those back I am going to get a Dragon cable on my Edition 8's... possibly silver. I am actually thinking of trying the Signature Studios at some point, just to have around for an alternate sound signature. Could be a while though. Extremely happy with my setup as is and already upgrading cables as we speak so, yeah. Maybe sometime in the future though. How is the comfort with the Signature Studios?
