Walls are no barrier to music appreciation with the new Zensonic Z710 wireless headphones. Using a wireless transmitter the headphones can deliver sound up to 100m from a home theatre, stereo or computer system. With the bundled internal batteries, the Z710s can be recharged by docking with the transmitter station. The headphones include 40mm Nd-Fe-B sintered magnet drivers and can reproduce sounds ranging from 20Hz to 20MHz at a signal-to-noise ratio greater than 45dB. The Zensonic Z710 wireless headphones are available in September from PC Range and Softline.
