The sound quality is excellent. The app performance is horrible. It gives wrong battery levels, drops out of Bluetooth sync regularly. Fights like hell to re-sync Bluetooth. There are earbuds on the market that give equal sound quality but much less app hassles. I would not purchase this product again.

Aurvana Ace 2 and Ace 3 have amazing sound for their class, but the worst app of its kind. How could they release something like this? Nothing really works.

It's see SB X5, but no any DSP settings, no speaker setup, just equalizer, mixer and direct mode which is useless because it uses the worst SBC codec - why ???? why no LDAC?
