The sound quality isn't anything super stellar, but that's also from an audiophile, so take that with a grain of salt. These sound better than I thought they would. Noise cancellation is iffy at best, but noise isn't much of a problem. Since they don't technically go into your ear, they are pretty comfortable and customizable compared to others through the Galaxy Wearable app. They stay in the ear much better than expected, and once you get used to their shape and put them in, they are an absolute joy. Samsung always seems to have something up its sleeve, and I think they nailed it with this one.
