The issue is that my left earbud is suddenly disconnecting and powering off and after that only the right earbuf works. This happens like after an hour of use so i dont think its the battery because i get them out of the case fully charge. This happens when i connect them to my phone and my laptop. An another problem i hear a noise while playing a video on youtube or music it sounds like the air its getting out of a balloon. What can I do?
