So i´m new in the audiophile world and i find it quite interesting, after sticking with IEM´s (klipsch s4´s) i´ve decided to step up a bit and buy some nice cans, and it all went down to this two headphones, the beyerdynamic custom one pro and the sennheiser hd 439 (i can get the fiio e6 with the senn´s) i´d like a good bass response, crisp highs and a well balanced sound, what would be better for me? i like rap, house, dubstep, rock etc. Also i have two questions about the fiio:
Is it really worth it?
Can i use it with the 3.5mm output in my ipod touch 5g?
Any kind of help will be appreciated.
