Over ear air tube headset for phone and media devices




Delivering sound via hollow air tubes rather than traditional wires, the DefenderShield® EMR-Free Over-Ear Headphones offer an incredible listening experience while protecting your head and ears from EMF exposure. Experience crystal clear sound quality while eliminating EMF radiation.

Airtube headphones utilise a hollow tube between the speakers and the headphones so the sound is transmitted through air only, allowing a safe distance between your brain and the radiation emitted from your phone or device. Sound is delivered to your ear with almost zero EMR.

The DefenderShield® EMR-Free Headphones are built with professional stereo-quality speakers, while air tubes increase space for audio development, producing more body and delivering superior acoustic sound.

Plug the headphones into your device’s 3.5mm audio jack, or into a headphone adapter.

Play music or audio on the device, and adjust the volume on both the device and on the headphones’ audio controller located below the air tubes. Make sure the audio is at a low conversational level (below 65 dB) before placing the headphones on your ears.

You can use the audio controller on the headphones to raise or lower the volume, play or pause audio, skip a track, and answer or end phone calls.


Experience crystal clear sound with the highs and lows of your music, listen to podcasts without distortion, and enjoy muffle-free conversations with your family friends, all while protecting yourself from EMF radiation.


When not in use, you can place the DefenderShield Headphones in the protective zippered carrying case. Follow the instructions below to avoid bending or kinking the air-tubing, as bent air tubes may prevent sound from reaching the headset.
