There was a bluetooth headset that was featured in popular science about 6 months ago or so. It was a headset that was in the ear and it had a new technology that if your surrounding area was loud it would switch over to using vibrations so that you could hear the person better and also they could hear you better. I want to say that it was a Jabra or a Jawbone, but I am not exactly sure. Can anyone help me on this?
