Just bought new ear plugs Sony WF-XB700 to replace my old Urbanista Athens ear plugs because of of them was not working. Now I have an issue with my vivoactive 4 watch. I have no trouble pairng the new ear plugs to the watch and start listening to the music. But as soon as I'm about to to choose a specific sport mode the music gets cut off. If I leave the Activity mode then the music start playing again. That being said I'm unable to listen to music while using e.g activities. How to fix this problem ?
