homely cans in our time -- wireless and otherwise -- which is why we were delighted to see that Sony's latest set of 7.1 channel headphones doesn't sacrifice form for function -- at least not on paper. The MDR-DS6500 setup offers up a slew of surround sound modes, including Dolby Digital, Sony's Virtualphones Technology, a 100-meter (330-foot) operating range, and automatic tuning. Sony's also promising 20 hours of listening for every three hours the things spend on their charging dock. We're not sure how much they'll set you back, but they are set for release sometime this May. Of course, we'll hold our judgment until we actually hear how they stack up. Full PR after the break.
