I have a Sena 50S and have used it several times since July. Last time out I connected to a friend who also has a 50S and i experience loud static crackling noise. It happens even when no one is talking. I am not connect to any bluetooth device at all. Just the other headset. My friends 50S worked fine and he could not hear the static cracking. It is really loud and makes the unit unuseable. We tried restarting the unit, reconnecting, updating the firware, full battery power, and it is still happening. Does anyone have any idea why this might be or how to fix it.
