I have a Nari (RZ04-02680100-R3U1) wireless headset. Occasionally I will lose audio in the left ear. This seems to happen if there is a spike in volume with something I'm listening to and occasionally I can hear a small pop before the audio cuts out. The only way I've been able to successfully get sound to come back is to repeatedly turn it on and off again until it comes back. If I move the volume sometimes I can hear a crackle in the left ear. It can be quite annoying. As far as I know everything is up to date and windows/synapse shows no issues with the audio
