Most of their IEMs are.
I actually own a pair of Skullcandy Titans I picked at an airport as I forgot my headphones for an 18 hour flight. They're actually okay for the $25. Here's a review from someone here: http://www.head-fi.org/t/455416/skullcandy-titan-review-head-fi-sanity-check
I would stay away from their other offerings though. Far away.
