Title: They're good.
Review: All insulated earphones sound unnatural because they seal off the ear outside air, so the sound quality isn't as great. Other than that, these are fine. The purpose for these is for the sound isolation and it does that well. If you're into sound quality, get the Koss Portapros which are complete open-eared so there is no sound isolation at all, but sound great because they're like speakers on your ears.
