The DefenderShield® Air Tube Headphones Delivers sound via hollow air tubes rather than traditional wires, and offers an incredible listening experience while protecting from Electromagnetic Field (EMF) radiation exposure. They are the best quality air tube earbuds in the world, and eliminates RF wireless frequencies due to being wired to your device. Hollow air tubes then switch the electrical signal to an acoustic signal, preventing any ELF (extremely low frequency) radiation from reaching your head and ears.
