The SportaPro is the perfect stereo headphone for music lovers who need to move from the boardroom to the locker room without ever missing a beat. Oxygen free copper voice coils improve signal transmission and conduction for cleaner, clearer sound. Perfect for the active listener, the SportaPro's unique headband design pivots backward at its base, easily converting from over-the-head style to a behind-the-head style that won't interfere with hairstyles or headgear like helmets or baseball caps. When not in use, the Sporta Pro collapses into a compact protective package that tucks neatly in a briefcase, gym bag, or backpack.
