Our Features and Advantages
Sound cavity free of magnetic field
There is no loudspeaker in the earplug, thus avoiding the direct harm to eardrum and brain brought by the 1000 Gauss permanent magnetic field and alternating magnetic field.
It isolates above mentioned magnetic field and radiation source. Moreover, air tube lengthens the distance between mobile phone and human body, which largely decreases electromagnetic radiation.
Three Electromagnetic Radiation Research Organizations have confirmed that air tube earphones is one of the best ways to reduce mobile phone radiation.
Metal shielded wire
It's made of strands of copper wires so as to prevent the transmission of high frequency electromagnetic wave, achieving quite good anti-radiation effect.
With good radiation-shielding performance, the outside low and high frequency electromagnetic waves
and noise waves can be prevented, enabling an output with high sound quality.
Besides, it strengthens the tensile intensity and extends the service life.
