It is a poor BT connection. Skips, dropouts and music speeding up to recover.
If my phone is in my front pants pocket, and the receiver is on my head, then the 2 are not in the correct "plane".
Side to side seems better than up and down.
There could be other interference due to radio or electromagnetic waves, as well as processor intensive background tasks or cellular connection dropout.
For constant blipping skips, restart your devices.
Working through all the factors to improve the situation my take some trail and error.
It is not your "device" alone.
