Titanium Sound in a Stylish Behind-the-head Design. With titanium-coated elements, the KSC55 delivers high quality sound performance to active and fashion-conscious listeners who never miss a beat and always arrive in style. The KSC55's behind-the-head design won't mess with hairstyles or get in the way of headgear like bike helmets or baseball caps. The KSC55 features dynamic elements for a wide frequency response from 15-25,000 Hz. A 2 mil. titanium coating on its mylar diaphragms increases the rigidity of the elements*, minimizing mechanical distortion and ensuring exceedingly accurate sound reproduction. Computer-optimized neodymium iron boron rare earth magnet structures mean the KSC55 delivers excellent volume, even with low-voltage MP3 and disc players. Oxygen-free copper voice coils improve signal transmission and conduction for cleaner, clearer sound. Foam earcushions with screened earcups** provide an open, hear-through sound – perfect for times when you need to be in touch with your surroundings, like while blading on the boulevard or listening at the office.
The result is a full frequency, clean sound that can add vitality to any workout or commute. At a mere 2 ounces, the KSC55 feels practically weightless even after hours of continuous listening. Its behind-the-head design accommodates most head shapes and sizes, and stays in place even during rigorous activities like running. Ideal for use with portables, the KSC55 includes a straight single-entry four-foot cord. A gold-flashed 3.5mm (1/8") plug, L-shaped to minimize cord stress, is included. The KSC55 will delight listeners searching for incredible sounding headphones that make them look good and look good doing it
