These are the earbuds that can be rinsed under water to clean for the next use. Ideal for strenuous workouts, their silicone diaphragm guards resist sweat and water-a simple rinse cleanses them for continued wear. Made by a company that specializes in music recording equipment, earbuds' in-ear design blocks out up to 20 dB of noise while delivering a wide frequency range (18 Hz -20,000 Hz) with minimal harmonic distortion (less than 1/2%), providing clear, crisp sound. They provide a comfortable, secure fit and will not fall out while working out, conforming to any ear size or shape with the included fit kit. The Kevlar-reinforced 2' cord, volume adjuster, and 2' extension cable provides superior strength and convenience, resists extreme hot or cold weather, and terminates in a standard 3.5 mm stereo input jack. Includes cleaning tool, cable clip, and storage pouch. (6 oz.)
