Bluetooth audio problem with Samsung Galaxy Buds Pro headphones

Hello, I have an annoying audio quality problem in listening to music between Epix2 and Samsung Galaxy Buds Pro headphones.


Strangely, the problem is felt while I run, wearing the Epix2 on the left wrist, while wearing Epix 2 on the right wrist the audio returns perfect.


I state that the 2 devices are updated to the latest official firmware version.


What can it depend on?


Thanks
