I bought the second one, the Califone, for DS last summer when we were taking a long roadtrip and I didn't want to listen to his DVD player for 9 hours at a time. I was really nervous that he wouldn't want to wear them, but as soon as he figured out that he couldn't hear the tv without them, it was all good. He likes them, even fell asleep with them on. They've been through two 8+ hour road trips, and two 24 hour roadtrips and they've been great!
