Hi, I recently purchased the Garmin Vivoactive 3 Series Watch and everyone is fine except that I can't use the volume control. I purchased a fairly cheap pair of bluetooth headphones (which are just earbuds so don't have any controls on them) and do not respond to the volume controls on my watch. At the moment the music is far too loud so I can't use them. Is there any way at all to adjust the volume of the headphones? Thanks
