These could be good headphones but the buggy technology coupled with the price meant that they had to be sent back.

I greatly appreciate AfterShokz's efforts to correct the problem I had and would highly recommend these headphones..

but I can not recommend these bone-conduction headphones.

These headphones are magnificent

These are excellent fitness headphones that stay put & keep me aware of my surrounding while bicycling.

They don't leak as much sound as I would have expected and actually can produce a pretty robust range of sound.
