I got my HD650 in the mail yesterday, and I was really enjoying the sound. It blew anything I'd ever listened to out of the water. Very pleasant, very comfortable.
Today, my E7/E9 arrived.
Wow. Just wow. I didn't think I could get this kind of sound of out a pair of headphones. Up until now, I had been debating if it was really worth the price tag, but call me a convert.
Welcome to Head-Fi. Sorry about your wallet!
