Only left earbud connecting to sound

I’ve received the aukey epT21 just a couple of weeks ago and for the last day and a half the right earbud is refusing to connect to sound.

Both charge as normal in the case and both have been reset multiple of times with all the troubleshooting methods in the booklet however the right earbud still won’t connect to sound. I should also mention that they both light green and red as normal.

Can someone please help me look into this as it is getting frustrating.

Thanks in advance.

Hello, could I get some insight in this please?
