I just recently got both the HD650 and HE500. The HE500 has much clearer sound but small sound stage. After owning them for a week, I prefer the sound the HD650. It's just sound better. It is more addicting and it makes me want to listen more. The sound of the HE500 is clear but without feelings. IOM, HD650 is the best.
