4-024 + 44-J: PRO Ear vibration w/cable control

Description

This new Ear-Vibration 2-in-1 Speaker/Mic is 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 earbone 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 earbone => 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.

Without a separate microphone that could be easily detected by people around you, this is also ideal for surveillance purposes and security at airports, casinos, crowd control at conventions and concerts, and other working environment requiring discreet communications.

The sensitivity of the newly designed microphone is greatly improved to cover a much wider range of frequency. Graph 1 shows that an ordinary speaker/mic best performs in the range of 1400 to 1800Hz while the newly designed model shown in Graph 2 provides execellent performance in the range of 900 to 3900Hz. With a much more sensitive microphone, transmission becomes clearer and distortion is greatly reduced.
