Right now I'm using my FIIO X3II>Schiit Vali 2>Grado SR80i. The treble is just killing me and easily fatiguing my ears. I've done some research and a couple cans that look like an appealing upgrade are The Sennheiser HD 598 and HD 650. I really can't try these out without buying them so which one would be the best choice?
