Mini wireless earpiece is a micro-mini wireless inductive receiver which transforms audio signal through electromagnetic induction. These products make the covert communication possible when it is inconvenient to expose earpieces. earpiece is widely used in many departments .Using this device;You can hear the voice from the person other side,and the person of the other side can also hear your vioce.
* Small, light, easy to conceal.
* Comfortable for wearing with an optimum anatomic design.
Mini wireless earpiece is a one-way reception equipment driven by electromagnetic induction and is used in conjunction with drive equipments, such as radio and mobile phone.
- Mini wireless earpiece consists of specialized chip, shell, faceplate, battery door, handle etc.
1.Battery door: Open battery door by fingertip, install the battery perfectly and push the battery door to battery box.
2.Handle: Clarity and high strength string help you to take out the earpiece from ear canal easily.
