Until now, if you wanted to energize your exercise with music, you were forced to compromise. Sport headphones fell out, weren't comfortable, broke, or just didn't turn you on musically. Many were adequate, but none excelled in every category. Which is why we're proud to introduce the iSport Immersion by Monster, the first take-no-prisoners sport headphones. They're designed by scientists and athletes to go where no sports headphone has gone before. For less than the price of a good pair of running shoes you can transform years of workouts: Basketball, running, weight training, yoga, or surfing...iSport lets you stay in your zone to run that last mile and pump that last rep.
