Fenix 7S Airpods Pro connection issue

When I'm out for a run with my Fenix 7S + Airpods playing Spotify from the watch, the headphones randomly loose connection every 5-20 minutes.

Waiting for 1-3 minutes and reconnecting usually fixes the issue, yet it's rather incovenient.

I did try to hard reset Airpods - that doesn't help.

Any help would be appreciated. Thanks
