Just got my DT770/250's in the mail today!
Right off the bat, i was a bit dissapointed. I hooked them up to my PC Tower just for kicks and listened to some music and did comparisons between it and the Sennheiser HD595's. Now, the DT770's sound stage was flat, eveything felt subduedand there wasn't any excitement or punch that was 'found' in the Sennheiser HD595's. However....When you hook the DT770/250's up to a good receiver it's a whole different ball game. They sound amazing!... First of all, like i mentioned previously, i was extremely dissapointed with my previous pair of closed sennheiser cans,they sounded very boxed in and artificial and killed my ears/head after 20 minutes of use. The DT770's thankfully sound pretty darn natural and don't have that nasty box in sound to them at all, plus they're very very comfortable. They're phenomenal in terms of isolation and
VERY minimal at sound leakage. An enourmous improvement over my HD595's in terms of that....I can finally game
without worrying that i'm distracting others, since my HD595's pierced through the walls, you name it. XP
The SFX when gaming sound more pronounced, crisper and striking. Mind you, i could probably achieve simular results with my senny's if i increase the trebble on my receiver. However my Sennheisers are a bit superior with Bass. Overall, the DTS's sound 'alright' when you're using an I-pod or computer for example, but when you hook it up to a receiver that can get the most out of them they sound fantastic. They sound like a completey different set of cans(far superior, mind you) when doing so.
