Europe is releasing light wieght WIRLESS headphones that incoportate both MUSIC and CELL PHONE uses. Do you think this will catch on? Do you think these headphones are helpfull to cyclists or harmful?

THANKS for your insight!

I think any time you cut off a sense you add danger.

No cyclist should be wearing headphones while riding. On the road it is necessary to hear traffic and it may also be illegal. On the trail it is necessary to hear people passing. Hearing your bike can also alert you to mechanical issues and flat tires before they become a serious problem.
