Sony WF-1000XM3 hissing sound with ANC on

[NightWolfix]

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?

That's common for anything that has digital processing like that. I think mine also had that. I returned them though because they'd make a clicking noise any time I moved my head slightly, but only with noise cancelling on. https://www.reddit.com/r/sony/comments/9if168/sony_wh1000xm3_poppingclicking_sound/

Noise canceling in a quiet room probably going to make some sound don’t think they are defective at all and would expect something like that.

Yeah I recall having returned the WH for the same reason. I was using them on the train and, at every light shake caused by the movement of the train on the tracks, it was making a clicking sound. So bad!

But my pair are the in ear version WF (with F), but I believe it is similar to the on ear case. I guess Sony has a long track record for making noisy headsets...
