Yes Frenchjay, i noticed the same, when i was playing some music on my Beats By Dre. Songs that usually contained much bass and used to sound crisp, now sounded bad and distorted. But as u mentioned yourself, it's only a beta 🙂
I guess the point of B1 is to check the functionality of the UI, and then later add the smaller details as Battery- and Performanceimprovemens for B2 (by then i guess they've sorted it out)
