Good design, good battery life.

They work fine for me. The only thing is 1) they lose their cushions pretty quickly 2) they don't last me more than 3 or 4 months before one or the other channels getting wonky because of the connecting wire. The sound is fine for my audiobook listening. The KSC-35 has better sound but the clip pinches my ears

Awesome but can be better.

Awesome, but the small controls are annoying. I think it's still worth it.
