I updated the firmware to 1.3.5

Result: Right earbud is super low volume. At first while having both earbuds on ears I thought that right wasn't working at all. I only realized it's "working" with super low volume after taking out the left one.

I tried factory resetting, uninstalling and re-installing the EarFun android application, but nothing worked.

 

Then after update 1.3.7 came out, updated to Version 1.3.7 but problem was not fixed. Right Earbud still super low volume and sound is muffled. The buttons on the earbud are working ok.

I tried factory resetting again, after update to 1.3.7 which didn't fix.
What else can I try?
