"Do NOT sweat on these headphones!"1.0 starson by KMcLachlan1
Features (except for iPod track skip - Apple's fault not Altec)
Ease of set-up
Cons: Will basically stop working if you sweat on them
Any music with bass will result in major distortion
Summary: I would not recommend buying these headphones if you plan to use them running or biking. Mine worked fine for about 3 sessions and then just stopped altogether. I returned them to Altec (who was very accomodating) and received a replacement. The same exact thing happened with the replacement set.
If not for this issue I would give them very high marks - especially considering the limited competition in this space.
