How to fix Aftershokz Aeropex?
Background : a few months ago, I bought an Aftershokz Aeropex bone conduction headset. They were brand new, I bought them in a second hand website and the person who sold me the Aftershokz didn’t have any receipt as a proof of purchase (I cannot use the guarantee and Aftershokz said they can’t help me on this…).
Description of the issue : after normal usage, the headphone turned off. It is now impossible to turn them on. I tried to recharge them, to reset them but nothing worked.
Is there a superhero out there who knows how to fix this issue ? Or is a disposable product ?
