Music unstable on BT (another thread!)

Hi, like many I got the 265 to pl;ay music without my phone. I have tried everything that has been suggested here and by ChatGPT to no avail. I am using quite cheap BT earphones, Jesebang YT18 but they are very well reviewed and I find them great in general. However, after 10 minutes, or maybe just less, they start glitching. Initially it is infrequent but then over the course of a minute it becomes very frequent and unlistenable. I turned the earphones off and back on, reconnected and then same thing happens, again, aroiund 10 minutes. Garmin support have been useless but if anyone has any new suggestions or a vague idea WHY this might be happening I would really appreciate it. I would buy new earphones if I was 100% sure they would work, even though that's ridiculous, but obviously I have no way of knowing.
