I'm still pretty haunted by the Australian ad campaign that raises awareness about iPod-listening traffic victims. These Vibe Body Sound Headphones would solve that problem by allowing you to experience the vibrations of the music, while leaving your ear canal totally open to hear the dangers of the outside world. That way, you're still rocking out, but you'll know when a car is screeching toward you or your boss is standing over you with a question.If the music is uncompromised, I think these headphones are pretty genius. My main concern is how they look and feel — I know they're not as bad as these wireless headphones, but the component resting on the back of my ear could look both funny and feel uncomfortable. They just might be the next wave in safe digital life though. What do you think, worth the $100 from Think Geek, or will you just be turning your music down a little lower?
