My pair of Dt1350's just arrived today. Played music through them without listening for about 4 hours.
Just a quick first impression:
I watched a blue-ray movie through an onkyo reciever playing into a presonus hp4 (that way my wife and I can both use headphones) They were very good with movie! Less sound stage than the hd800's I usually use, and not as "full" sounding. But I did not get that "I am missing something" feeling while watching. Bass was tight and extended, everything sounded smooth and clear. Explosions still had impact, but less of the "thump!" though...In a quick comparison, I liked them much better than the DT770's that my wife chose to use.
I then listened to some music, Mackbook Pro (lossless +wav) > Nuforce HDP > dt1350:
I was surprised by the level of impact from the drums and guitar listening to kid rock's "rock and roll jesus" album and juno reactor's pistolero.
I tried: diane krall, katie melua, clapton, willie nelson, faure, nirvana, johnny cash, zepplin, maceo parker, mingus, monk, lady gaga, beck, moby, kanye, sugarhill gang...I thought it handled everything well enough. Only on classical pieces did the smaller sound stage start to feel remiss. And the bass could have been a little more plentiful on the hip hop and rap, but it was extended and full enough, that I could still enjoy listening. I have had other phones that put me off enough with certain styles of music that I could not listen with them. So far, these seem to work well enough with everything I tried to be enjoyable.
(I agree that the guitar on radio head's ok computer album did not sound so great with these, but I think it is the recording. 'll have to compare with the hd800's some time, don't feel like warming up the tubes right now)
I tried them right out of the macbook pro's headphone jack (after listening through the nuforce hdp for a few hours) and could not stand the sound. it sounded like a different can to me...Mids dropped out too much and was it sounded much flatter over all. the bass may have been more emphasized, maybe because everything else recessed, but was not as impactful or extended. I think the dt1350's are MUCH BETTER amped! I will give them a few more days, but if I continue to like the way they sound I will have to break down an get a portable amp for these...
After 4 hours wearing these my ears are bright red! Comfort has been fine, but I am going to stop wearing them until tomorrow...
I bought the dt1350 as a portable, closed option and I am very happy with these so far!
