Acix, have you tried the Shure SRH-940 or any of the KRK headphones? I bet you'd like the KRKs for studio use.
These days, nobody seems to know what a flat headphone sounds like. First it's the HD-600, then the DT-48, then the DT-880, then the K702.
Now I often hear it's the M50 and D2000. People say the D2000 has a "V-shaped" sound, but the graphs seem to say otherwise. Sometimes I don't even know which is truly flat.
Can't even tell from a graph half the time.
Best thing to do is buy a bunch to try out and sell the losers
Picking between the K702 and DT-880 would be tough for me. Both had issues for me.
My pick would be the K501 probably and my ears seem to think so too. I'd like to try the SA5000 sometime.
