Input:
I've never listened to the HD650's (no retail store nor owner nearby) but I have read about them and these also from many sources and I concluded that the HD600's were so close sounding to the HD650's that it wasn't worth the extra $$$ to to buy them. I've kept reading and checking the performance of the HD600's often and I'm still happy with my choice. I've seen both sold on Amazon for less multiple times. Check the price history and grab one or the other or both on sale. It should make you happy.
