The foneGEAR Cord Free headset is a wireless headset with a difference. It uses magnetic technology to get the sound from handset to lughole. Why? Well very low power consumption for one thing – how does 25 hours of talk time from one measly AA battery sound? And by the way, the AA battery is used as a charger for the headset’s battery, instead of using AC power. And maybe health benefits too?

‘Unlike RF technologies, Aura’s LibertyLink based devices transmit extremely low power (about 100 nanowatts). In addition, the use of a low frequency band (10 – 15 MHz) significantly reduces the RF absorption by biological tissue…if all the emitted power were concentrated into 1 square mm, the measured SAR would be 16,000 times less than the U.S. limit..’
