I'm an early adopter - got them on the day of release.
There appears to be a glaring issue, and I wonder whether they're particular to only my pair.
Basically, whenever there is about to be sound played - such as unlocking of the phone, start of a phone call or music, white noise hissing appears, sometimes with a "pop" and then lasts about 2-3 seconds after the sound stops. Even if no sound is played, quick locking or unlocking of the phone results in a 3 second noticeable white noise hissing sound.
Please advise. Does anyone else experience this issue?
