My first post, so go easy on me!
I upgraded from DT770s to the Ultrasone 900s recently, I use a macbook pro running ableton live with an Apogee Duet. I most make music where bass features as a main instrument, or is certainly important.
Here's an example - http://soundcloud.com/benjaminburling/briefs-05e
I have tested my ultrasone 900s now for about a month.. although the spacial quality and top end are really terrific the bass leaves a lot to be desired. And, thats a massive problem, overall the sound is hollow, I find.
I've screwed them in tightly. - still a problem Im afraid.
Also, another gripe.. what is with the fit? My DT770s fit like a glove and cut out loads of sound, my ultrasone 900s are not tight and almost feel like theres a gap in the lower portion of the cup (is that the word?)
I find myself constantly shifting them.
If I press them tighter to my head I have to say the sound improves, but thats using both my hands.
I really hate to moan but I wanted to love these head phones and so far the only improvement is in the high end and the cost of the bass and fit.
Please offer me advice because im thinking of sending them back in case I have a faulty pair.
