Plantronics has lately made a point of delivering solid wireless audio for relatively little cost, and that's particularly evident this year. It's releasing a refreshed headphone lineup that sees it both push into uncharted territory and lower prices. The centerpiece for the fitness crowd is the BackBeat Fit 3100 you see above. It promises true wireless listening with ear hooks that should keep the earbuds in place during a workout, with audio awareness that could keep you safe during an outdoor run. It's available now for $150.
