For the external mic, normally we send it to our clients as a gift, cause our unit have the built in internal mic. When you plug the external mic, then it will work automatically, but if you close the external mic or mouth to the internal mic hole, sometime both the two mic work. So we suggest you don't use the external mic when the internal mic work well, or you can choose to use another high quality external mic to check. And you can plug our external mic into your phone to check if it's broken or just don't working well, hope you can understand.
