Sennheiser is hoping to attract audiophiles who want to cut the wire with its new RS 220 wireless headphones. The headphones can reproduce lossless audio with a frequency response of 19 – 21,000hz while letting you enjoy your music wirelessly up to 300 feet in any room in the house. Music controls and volume are available right on the headphones and the batteries will allow for up to eight hours of playback. That equals a viewing of the complete Transformers trilogy with the Bayhem turned up to 11 without the risk of getting kicked out of your thinly-walled apartment.
