When listening to music, audio cuts off multiple times for a few seconds and then works again for something like 3–15 minutes and then it randomly cuts off again. This happens with absolutely no visible changes. Nothing physically moves and still it can happen, while transmitter and headphones distance is less than 1 meter. (I don't know if WiFi traffic or something like that might interfere.) In any case, this happens way too often and with the same exact setup, on Sennheiser Momentum 2.0 Wireless there is no problem. The audio never cuts off with those headphones. Of course I tried already SBC and AAC (in the Headphones app, "Priority on stable connection" and "Priority on sound quality"). No difference.
I'm not yet sure how much this problem occurs when playing from iPhone and iPad, however it certainly happens very often when playing from Windows 10. So, what can I try to get rid of the audio cutting off problem? As said, the particular BT dongle works fine with Sennheiser, however does anyone have experience on solving the audio cutting problem by changing BT dongle to some specific model?
It seems it's very difficult to find out what codec Windows 10 is using to re-encode for the Bluetooth transmission stream. I read https://habr.com/en/post/456182/ for lots of good information and found that https://www.bluetoothgoodies.com/tweaker/ would let me know the codec in use. But none of that helps me solve the audio cutting off problem.
