I recently bought these wireless headphones (Anker SoundBuds Tag) but they did not working so well on my redmi 4X: the volume was fine during phone calls, but it was exteremely low on other apps (such as spotify, youtube, etc).

Testing the same headphone on another device (iPad) they worked fine.

I am returning the headphones anyways but before buying a new pair I was wondering if there were any compatibility problems between the 4X and some models.

FYI I have the latest build of MIUI

Would you have any suggestions for good wireless headphones, less than 50$ , water-resistant, and with commands that can be used not only to control music but also start calls? (for example through google assistant)
