Headphones let us escape to our own private bubble

cheap beats by dre let us escape to our own private bubble─which is not a good idea when walking, running or bicycling on busy streets. This year's Consumer-Electronics winner, AfterShokz, addresses this problem with sports headphones that loop over the ears like other headphones but send sound waves through the listener's cheekbones。 Environmental isolation is a serious problem; a recent study of pedestrian injuries found that three-quarters of people hurt or killed after colliding with a car or train were wearing cheap beats by dre. By transmitting music directly to the inner ear, AfterShokz headphones don't block out sirens, warning shouts and other background noises. The bone-conduction technology used by AfterShokz was developed in 2001 by Shenzen, China-based Voxtech Ltd. to help soldiers in the field listen to radio-based commands while staying alert to their surroundings. A Voxtech unit, VoxLinc LLC of East Syracuse, N.Y., introduced the product in January.
