Hello headFiers   I have recently upgraded to DT 770 PRO 80 ohms and have been using a Schiit Fulla.  I have been observing noise from my USB ports.  It's irritating when I am not listening to music and have my headphones plugged in.  Any suggestions to get rid of it?   I have tried...

So I just upgraded from Senn's on-ear momentums to over-ear momentum. Although i like the sound.  I do find them uncomfortable after less than hour of listening session. My Sony MDR-V6 on the other hand are so much comfortable even for more than 4 hours of continuous listening on stock pads...
