My new Sony WF 1000 XM3 make a continous background white noise (a very light "sssss") while the noise cancellation processor is on and music is not playing. It can be normally heard only in a quiet room, but it is very annoying. The noise goes away when I turn noise cancellation off (ambient noise control off). Is it the same with your pair?? Shall I return them?
