I've used two 3dio so far and both only the right side is broken.

  The second is that it works properly, but as time goes by, the right sound becomes bland and then becomes almost invisible.
  I didn't treat my right microphone rough or humid. My second 3dio's right ear died, even though I was careful with everything to be aware of. 
  What's the reason...

  Hi @Ahn SooBeen,

  Thank you for reaching out to us. I'm sorry to hear your microphone isn't working properly.

  Have you tried replacing the 9V battery? When the level of the battery inside the microphone is low or dead, then the microphone will stop working or one of the ear will become quiet.

  Here is a quick tutorial video on how to replace the 9V battery inside the microphone: https://youtu.be/7wF1YtdqUV8

  Give this a try with a brand new battery. Please let me know if the microphone still is not working and I’d be happy to help further troubleshoot.

  Best regards,
  ~Brian
