The PDF “slides” for a lightning talk I gave at this month’s MHV LUG meeting: MHVLUG Lightning Talk – Bose Hearphones.
You don’t get my patter, but perhaps you’ll get the gist from the pix.
Summary: I like ’em a lot, despite the awkward form factor and too-low battery capacity. If you’re more sensitive to appearances than I, wait for V 2.0.
FWIW, I tinkered up a beamforming microphone array with GNU Radio that worked surprisingly well, given a handful of hockey puck mics and a laptop. Bose does it better, of course, but I must revisit that idea.
