Sony wh xm4?

Hi, I bought before 3 months ago sony wh xb900n but I had problems with the headphone the issue is the sound keeps going for second every few minutes of using and if I go to the other room and it's less than 5 metres the sound also goes so I returned it back. Now I bought before 4 days ago sony wh xm4 and I have same problem there's like a tone comes for a second from time to time it's annoying because while I'm listening to the music I keep hearing this like a tone and the battery is 80 percent the phone in my hand but I'm tired bieng having this sound. Does anyone have this issue?
