Macbook Air M2 interrupts sound when 3 Bluetooth devices are connected.

Good evening team! For many months I have been trying to find a solution for such a problem: I have Macbook Air M2 with an external Apple keyboard and an Apple mouse. I have Bluetooth headphones: ATH-M50xbt, Sony WH 1000 XM 5, FiiO EH3NC. When all three devices are connected (headphones only one, at one time) at the same time, the sound is interrupted in the headphones every 2-4 minutes, literally for a fraction of a second, there is a feeling from the 2000s, when the CD player did not yet have an anti-shock system. It just ****** me off terribly. I even reinstalled the system, but the problem remained. Reset Bluetooth and about 100 other recommendations. Only disabling the keyboard or mouse helps, but this is not possible when using an external monitor, and most importantly, there was no such problem on my Macbook Pro mid 2015 even with 5 devices connected at the same time. What can be done about it? The problem is clearly not in the headphones, I checked all three. I have AirPods 3 with them there is no such problem, but they are not suitable for music for a long time (I don't want to offend anyone).

Pls help!
