MR P I also have a Pro tec Mercenary 'Andreas Wig' I bought it very cheaply at a Van's skate shoe retail park shop, as I have always worn Pro tec helmets for skateboarding, they just fit and I know last a while. Had it last year for a week in Bansko & a few days in Lithuania, it was fab for comfort and the sound is really very good,, much better than wearing ipod ear phones of any sort all day all day, goggles fit so I am a happy bunny, I'm sure you will enjoy yours.
