This was also an issue in Ubuntu, so it’s not an EOS/Arch specific issue. Have never had this issue in Windows or with any other OS using those same earbuds. Here is what happens:
I’ll start by playing a video or a song (typically youtube/spotify) using my Bluetooth earbuds. Sometimes, with no warning, I’ll get a weird cut-out for 3-4 seconds, then audio will resume but with a 1-2 second lag (behind). Disconnecting and re-connecting from the device always resolves the issue. However, it almost always starts happening again, often in smaller intervals. There are times when this happens every 40 seconds, and watching a video is essentially not possible. Re-pairing or rebooting seems to stop it from happening for a while, but after a day or two all the issues will start over again.
Please see below all relevant information (let me know if additional information/debugging is required to fix the issue):
