The material seems pretty flimsy. It's cool that they fold up for travel, but I wouldn't use them snowboarding. In fact, I wouldn't use them for anything active. They work best if you're just sitting and listening.
Cool color combos. Sounds pretty good. And does a pretty good job of keeping the music in your ears. I used them at work (desk job) and a few times I thought my coworkers could hear the music, but they didn't.
