Bass and Treble buttons on the remote

Hey, everybody.
Never used the Bass and Treble buttons on the remote.
Decided to give it a try, but it turns out that there is no feedback from the app and no change in the sound at all. Tried it on s10 and A50.
Does anyone have these buttons working or have worked?

Hi, it should work and also will sync with the level no APP. And you could check the effect on APP first, it’s easy to hear the difference. You can find it in the settings page of device, named ‘EQ’ although not very accurate.

Tried it again. No change. The LED on the remote is flashing, but I can’t hear or see any changes in the app. Maybe the problem is the remote… The other remote isn’t with me right now. I’ll check back later.
