Wire Shield Features Model & Price Instructions

AegisGuard™ Headset Wire Radiation Shields prevent up to 98% of a cellular or cordless phone's radiation frequencies from being transferred through a headset wire. They can be used with any type of wired or air-tube headset within the specifications presented below.

Wire-Shield.jpg (3748 bytes)Unlike ferrites, also know as ferrite beads, that do not provide protection from wireless phone frequencies, 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.

They 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.

When using an AegisGuard™ Headset Wire Radiation Shield, radiation remains in the wired or wireless product instead of being transferred through the headset wire. For maximum safety, use AegisGuard™ LS Radiation Shields for your phone and other wireless products.
