Airstream cutting in/out whenever using tablet

I think a BT request, like a phone call, keyboard click, or text notification, will override the airstream use.

i tried isolating power (using power bank), i’ve also tried plugging in my samsung tablet/phone/laptop (acer pretitor helios neo 16) to my tv connecter (powered by power bank) but i still get a 60 hz hum,in right ear when there’s no audio (on laptop aux port/ galaxy s22u (using aux adapter - teleadopt) but not my tablet (plugged into aux via adapter - creative SoundBlaster)) ground loop will happen at times (either plugged in to wall or powerbank) also the hum will happen if i unplug the aux cable from audio source it’ll get louder when i touch the port
