This has been a recent development in the last month or so. I have tried three different sets of bluetooth headphones and it happens on all three. If i go for a run, the music will periodically crackle or just kick out for a split second. And it does it randomly. I could go a minute jogging and then it happens a few times in 20 seconds. I have also noticed it happens more when I run. If I walk, it happens way less frequently and if I am sitting at my desk, the music has no issues. I have restarted the watch and that did not work. Next step might be to just reboot the watch. But the fact it happens with more frequency as I move my arms faster makes me think it is a hardware issue as opposed to a software issue.
Any suggestions?
