Effective shielding mobile phone signal jammers of various radio signals, block (interference) radios and communication between the receiver so that the intercom system on the grafting of various types of stealth wireless headphones (including anti-shielding, anti-detection headset) does not Work (strong noise or no sound), only the shield radio signals, without affecting the normal operation of other electronic devices, environmental protection, electromagnetic radiation through rigorous testing, the samples were measured electromagnetic field strength is far below the "electromagnetic radiation protection "(GB8702-88), without any impact on the human body.
