I've recently bought Samsung Galaxy buds and Samsung Galaxy Active Watch and they were paired and working fine. I use them to listen to Spotify when running. All of a sudden the sound is faint. I have to turn up the volume to max to hear anything at all. Prior to that I could hear music clear and loud on 6 setting. The headphones still work fine with my Samsung s9 phone and Samsung A7 tablet. I've tried the usual off/on. Restart etc. Nothing seems to increase the volume. Please can anyone help me with this issue?
