Its highly recommended that you use an RF3 Air-tube Headset with
a Wireguard and Pocket or Belt Clip Shield! "See Gold Package"

• WireGuards are the ideal add-on accessory for any headset using a AIR-TUBE design for RF reduction. Even Air-tube headsets have a wire "often in contact with your body", and a WireGuard prevents the wire from acting as an effective high frequency antenna!
• The WireGuard suppresses radiation transferred up the headset wire to the earpiece without affecting sound quality.

The wireguard is a reusable radiation suppression clamp-on device similar to a clamshell. This device clamps over the headset wire above the plug that is inserted into the phone. It incorporates a ferrous composition based material which interacts directly with the high frequency energy and suppresses it effectively while allowing the voice signal to pass through to the earpiece unimpeded. The housing is a white or black composite manufactured using nylon resins.  FITS ANY HEADSET!

The effect of magnetic material on a conductor
Current flowing through a conductor creates a magnetic field around it. Transfer of energy between the current and the magnetic field is effected through the "inductance" of the conductor - for a straight wire the self-inductance is typically 20nH per inch. Placing a magnetically permeable material around the conductor increases the flux density for a given field strength and therefore increases the inductance.

Wires or cables connected/extending from electronic devices using radio waves (such as cell phones), if not shielded will emit over ambient rf radiation levels. To suppress high frequency rf radiation from interacting with sensitive electronics and biologic systems (cell phone users), we offer a line of clamp-on ferrites suppressors. Our ferrites aim to effectively shield the harmful electromagnetic fields from traveling along computers wires, electric wires and cell phone headsets wires ect.

Using a cell phone with a hands free headset that is NOT shielded will dramatically increase rf radiation exposure to DNA within vital organs. All studies have proven in the likely hood that microwave radiation from a cell phone handset is hazardous. WireGuards help prevent the possible 300% increase in RF Exposure to the brain that can happen when not using a shielded headset!  

One other major concern of using a headset for hands free usage is where the phone itself is placed.  When hands free use requires the phone is held near your body, proper Body Shielding must be used! (Pocket Shields & Belt Clip Shields)

1.  Position headset wire just above the plug into either 'V' Channel. 

2. Close one side over the other, verifying the wire passes through the opening on both sides and the side tabs lock.

3. To transfer to another headset, carefully open the side tabs using a small screwdriver.
