AegisGuard™ Headset Wire Radiation Shields prevent up to 98% of a cellular or cordless phone's radiation from being transferred through a headset wire and when used with an AegisGuard™ Earpiece Radiation Shield, up to 99.9% of the radiation normally emitted from the earpiece is deflected away from the ear. See Tests for additional information.

AegisGuard™ Headset Wire Radiation Shields
Unlike ferrites that provide no protection whatsoever from cell phone radiation, AegisGuard™ Headset Wire Radiation Shields consist of a proprietary metal and ceramic non-magnetic ferrous material tested at frequencies emitted by cellular phones and headsets, plus higher and lower frequencies. They are embodied in a durable nylon housing that clamps over a headset wire above the plug which is inserted into the phone.

AegisGuard™ Headset Wire Radiation Shields fit all cellular and cordless phone headset wires and interact directly with the high frequency energy, suppressing it while allowing the voice signal to pass through to the earpiece unimpeded. They significantly reduce radiation absorption by body organs and into the head via the ear canal, and block up to 98% of a phone's radiation from being transferred through a headset wire without affecting sound quality, power level or battery consumption. Lightweight and easily installed (no tools required), they are also easily removed for transfer to another headset.
