I was having the same problem with the pair and contacted customer support I was browsing this forum for any way to solve it. Eventually, I contacted customer support. They replied:
Dear Draken X,
Thank you for reaching out to us.
I apologize for your headphones not working correctly here. I know how
frustrated you are. We hope we can make up this inconvenience. There is some
troubleshooting that we could try:
left earbud in your ear, double tap to see if you can hear any on or off beep
Deleting the pairing history on your device.
Put the earbuds back to the charging case and then taking them out again,
please double tap both earbuds simultaneously and put them together.
Turn off Liberty+ by pressing the button for 5 seconds until you see the red
Put Liberty+ in the charging case, take them out to retry.
If it not works, Please try pairing Liberty+ with another Bluetooth device.
I was nervous because it failed 2 times but the 3rd time, I haven't been so excited to troubleshoot something so successful. I was afraid to RMA them or something, I dislike dealing with those type of hassle and I'm glad both earbuds playing music and not just the right side.
If anyone has this problem, please give this instruction a shot or two before giving up.
It works for me, just be patience and persistent,
Both of my ears are enjoying music
