Possibly a very silly question here from a newbie, but would appreciate an answer from any current owner of a Bose A20 headset as I’ve found conflicting answers online…
I’ve just purchased a second hand pair and when they are turned on in a quiet environment (plugged in or not) there is a very noticeable hissing/static noise, about the volume of a running tap. This becomes less noticeable with louder background noise, in a GA aircraft with the engine running it can barely be heard at all - is this normal for an ANR headset? I just want to check as they were advertised to be in perfect working order.
I’ve tried cleaning them out and changing batteries.
TIA
