Poor usage with OWS OLA headset
The whole app is terribly buggy to the point of being unusable. Pairing order between button and headset matters. Expect have tone-pair multiple times. Equalizer doesn’t work with an error showing up that says “equalizer not applied”. If youbisenitnon yellow mode it can completely upset ability to use with music. You’ll have to exit the “talkie” tab and go back to music. Basically, the thing is a mess of an app. The headset works ok but don’t expect good performance out of using for anything else and or with the included button.
