This new Ear-Vibration 2-in-1 Speaker/ Mic are designed for professional use. The performance of this new model is greatly improved comparing to the ordinary Ear-vibration 2-in-1 Speaker/ Mic.
Apart from being a headphone, the earpiece also translates the vibration of your ear bone into an electric signal and transmits it through your transceiver to another two-way radio. With this 2-in-1 speaker/ Mic, you can get rid of a separate microphone.

The mechanism works as follows:
Mechanical vibration from ear bone => electric signal => transmitted to radio transceiver

Since the speaker/ Mic is hidden in your ear canal, it is not sensitive to any background noise. This is exceptionally ideal for usage in high ambient environment such as driving, riding motorcycles and bicycles.
