This is a throat microphone headset adopted as equipment for special vehicles by the fire department. It is more compact compared to conventional throat microphones. It maintains high call quality without picking up noise even in high-noise environments. Additionally, the "throat microphone & transceiver set" allows for stress-free communication in noisy environments, such as factories, by combining the throat microphone with commercially available transceivers and a branching cable. You can also check images of the transceiver set and how it is worn in the photos. 【Features】 ■ Adopted as equipment for special vehicles by the fire department ■ More compact compared to conventional throat microphones ■ Maintains high call quality without picking up noise even in high-noise environments *For more details, please refer to the PDF document or feel free to contact us.

We handle "non-contact connectors (plug/jack)." Since they are non-contact, there is no contact failure due to oxidation or wear from long-term non-use. When used with earphone plugs, there is no noise such as crackling. Additionally, due to the electromagnetic induction connection, they are floated and can be applied to medical devices and other applications. They are also resistant to dust and water. They can be adapted to various applications depending on your ideas. 【Features】 - No contact failure due to oxidation or wear from long-term non-use, as they are non-contact. - No noise such as crackling occurs when used with earphone plugs. - They are floated due to electromagnetic induction connection and can be applied to medical devices. - They are resistant to dust and water. - They can be adapted to various applications depending on your ideas. *For more details, please refer to the PDF document or feel free to contact us.
