About a week ago the left ear became much much quieter than the right. I've confirmed there is sound coming out, but it's almost non-existent.
I've confirmed that I have the most up to date software, I've also shut them down and repowered them and tried with different devices but nothing has fixed the issue.
Thanks for reaching out and welcome to the Community! That's a shame that you are experiencing low volume from your left headphone, this is not what we want at all. I am more than happy to provide some additional troubleshooting you, it sounds like you have already tried some great steps; lastly I recommend you try clearing the pairing list.
To clear the product memory of connected Bluetooth® devices:
If you are still getting low volume from the left headphone after clearing the pairing list, then I recommend that you call the customer care team as there is no more troubleshooting to go through and the headphones may need to be exchanged.
I hope this helps, if you have any further questions please get in touch.
