Have those of you who don't run with headphones due to safety concerns seen the Aftershokz Trekz Titanium and Trekz Air headphones? They use bone conduction technology to transmit sound through your cheekbones and sit in front of the ear, leaving it free to hear your surroundings. These were a game changer for me and especially welcome as I hate having earbuds stuck down into my ear canals. Not trying to convert anyone over who's not interested, but if you would like to be able to listen to things during running but were concerned about compromising your safety I think this design offers the best of both worlds. They also work great with glasses and sunglasses, too. BTW, that's not me in the picture. I've got more hair and don't look nearly so good...
