Headset with USB plug for notebooks, computers
The permanent alternating magnetic field of loudspeakers with the interaction of the magnetic field can damage the brain and eardrums.
To solve this problem, the FH1This headset uses an electromagnetic radiation attenuation principle with quadruple anti-radiation technology, including metal shielded wires, air tube, non-magnetic speaker and passive microphone. This extends the distance between the radiation source and the human body, which largely reduces electromagnetic radiation and achieves a great anti-radiation effect. Ideal for call centres, business or private use.
