wireless air tube - unlike regular Bluetooth tube, is on our chest and not on our ear and through it comes the hollow pipes that prevent the radiation from reaching our head.
The discharged radiation from the cell phone is blocked and discharged outside due to radiation matter that is constructed on the internal side of the device (radiation blocker card that made of metal alloy), so when we speak with wireless air tube we can be up to 10 meters from the cell phone and be protected from the cell phone radiation!
