The last wireless headset (Hyper X cloud flight) I tested had a constant white noise, very unpleasant as long as there was no other noise, does this headset also have this white noise? (All those who tested it with me did not hear this noise and did not bother them, but it was very annoying for me), from what I had read, itI've read that it might be due to the fact that it was linked to the transmission medium (bluetooth I think) so all bluetooth headsets would have this white noise?
