Garmin Fenix 7s vs Samsung Galaxy Buds

Recently purchased a new Garmin Fenix 7s and been having a small problem when i pair the galaxy buds to them.

When I go for a run and listen to amazon music the connection between them is pretty poor. It's like the signal is weak between them so the music kind of pulses when running.

The watch is on my left wrist and I am 185m tall but surly the distance can't be the issue?

Anyone had any similar problems? Any obvious fixes for it? As far as I can see all software is upto date etc.

Thanks in advance
