It seems to be better in beta 4 I noticed that the previous betas seemed to be quieter and just testing with Sennheiser Momentum 2 Wireless it started to uncomfortable above 75-80% on a couple to Apple Music tracks I picked at random.

I am sure when listening on previous betas I could get up to nearly max and not feel it was getting uncomfortable.

Yes - it seems to have been fixed in beta 4. Good news! :)

Awesome glad to hear, maybe I'll just download iOS10 again.
