Crutchfield Customer Review (What's this?)
I've owned the Sennheiser HD650 for about a decade and have enjoyed it greatly. Even though this new headphone is not yet broken-in, I could still hear a noticeable improvement over the HD650. The 650 had a somewhat veiled sound and the high frequencies were somewhat muted. Both of those shortcomings seemed to have been corrected in this new model. I look forward to even better sound once I rack up more hours of listening.
Pros: Clean sound Excellent dynamics Highly detailed
