Fixed: Soundcore Liberty wireless earbuds - no sound through Right, button works to start/stop play

Current manual

and excerpts

My suspicion is that at one point, I used only one of the earbuds. Since then, I have not had any sound on the right side. I tried multiple resets as above, getting the red and pink lights. The battery shows 100% when connected via Bluetooth, and the control buttons worked. But  no sound on earbud marked Right (R).

Sometimes you just need a kiddo to kick you in the backside, and make you try again. 

A combination of these made balanced sound work again on both earbuds:

1. After a reset sequence, only keep the right one outside the case (previously no sound) .Connect to device.
   
2. Increase volume on device to max (I heard some faint squeaks when a voice was playing, this gabr me hope).
3. Take out the rubber covers and clean the best you can. I used a sharp needle in the holes the sound comes through. CAUTION and use at your own risk. 

This was after months of the thing not working. Please leave a comment if this resolves your issue. Thanks.
