- The Edition 8s have somewhat more mid-bass than the HD 800s; Edition 8 bass balance seems better, though I think taste is a factor here
- The HD 800s seem to have better deep bass
- The HD 800s are slightly softer; they are also more forgiving of bad recordings
- Instrumental “air” seems higher on the HD 800
I think very highly of the HD 800s. The Ultrasone Edition 8s are an alternative that I think many people would enjoy. Overall, they sound different enough that I suspect most people would be able to pick one over the other fairly easily. We’ll see if that feeling holds up over time.
