I like burn-in. Is it psychocandy? Maybe, but I'll keep doing it. Well, the HD 650s are my last pair of cans for a while, so this is it. I've got about 35 hours on them now, and with my newly repaired Lyr, I'm about to go to town
Let the HD 650s vs. HE-500s battle begin.
Have fun, my money is on the HE-500's as their treble is there and the bass more potent. I'll be curious as to how they hit your ears.
