Sony has just recently pulled the covers off some revolutionary ear buds. The Sony MH907 Ear Buds ($39) are the worlds first motion sensing headphones. They use human skin as a conductive surface and are able to automatically start playing music once both ear pieces have been inserted. Also, if you are receiving a call all you have to do is take one ear bud out and they will know to answer the call. These new headphones are sure to have an impact in the industry over the next few years. Be sure to head over to Sony and check them out.
