Put these in my ski helmet. Work great, quality sound for the price.

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
