My earphone did a static noise and now that side of won't play any sound unless I move it around and only plays for maybe less than a second before not playing anything again

Hello everyone, I bought the Dragon Ball Z x Final Audio True Wireless Bluetooth Earphone from Final and it worked well for the first month but something recently happened where the right side of the earphone won't play any sound unless you do some weird motions and even then it only plays for less than a second.

I tried everything from the manual and nothing seems to work, I'm starting to believe the problem comes from something inside of the earphone.

Here's the link the official page of the earphone and I can upload the manual if need be.

Thank you in advance.
