I am using them with a Xonar DG.
Right first impressions of the build quality are good. They feel sturdy even though they are still mainly made of plastic. The earcups are very comfortable and fit right over my ears and so is the headband, though it could possibly do with a little more padding. My Creative Fatality 2 headset (now broken) has the same headband and it is to be used very loosely. There is no need to have it clamped tight like on other headphones as it does just sits nicely on the top and you get now movement even with pretty vigorous head movement.
These have had no burning in time but I am giving them a little workout with some David Guetta but already I am loving them. They have more soundstage than the original CAL! and I am hearing new things in the background already. I can't compare them to much higher phones as I have none but compared to my Panasonic RP-HTF600E-S they are a world apart (incidentally they are back down to £32.99 again so have become a very good budget headphone as they were around £50.00 last week).
I will update further as I test them with other styles of music and some gaming but at the moment, I have a big smile on my face. They just gave me little goosebumps listening to Subliminal by deadmau5. They go a lot louder than both my Fatality, Panasonics and CAL's.
My only initial grips is the fact that the cable at the headphone end is a 2.5mm socket and I am likely to want to replace the flat cable with a much longer one as it is quite short.
