Up to now I was using the AKG K518 but I decided to get a new, better pair of headphones :)
I borrowed 3 different models from my friends, tested them on my Xonar D1 + Yamaha RX-V350 amp and all I want to say is:
1. Beats Solo had too much bass and no treble at all
2. Beyerdynamics Custom One sounded nearly the same as K518 (they have slightly soften treble, more muddy bass and as K518 - no scene at all)
3. And then I listened to Sennheiser HD 595 and I have to say that the are just near perfection. I really like the natural sound and hude scene of these ones. The problem is that they are not longer produced, so there is my question: What headphones (to 200$) do you recommend? After reading lots of reviews I think about AKG K550, Sennheiser HD 598 and Beyerdynamics DT990 PRO, but I still haven't listened to none of them so I don't know what to expect. The other thing is, that I won't be able to test those in store just like I've been testing the HD 595 comfotrably in my home with my PC and Amp.
