Venu 3 - Bluetooth interference, bad connection with music.

I recently bought a Garmin Venu 3 coming from a Vivoactive 4.

Several times now i have experienced connectivity issues with my headphones during workouts. It works for a while and then it sounds like  the music actually slows down and a lot of disturbance (scratch noises) is also present. A reboot of the watch and it works again.

Tryed this with 2 different sets of headphones. Jaybird Vista 2 and Bose 700

I have tried unparring and parring again and full reset of the watch but the issue is still there.

Any one else?
