These are the patented earphones that produce high-fidelity sound while minimizing potential damage to one's hearing. Each earbud faces the speaker away from the ear (it won't disturb those nearby) yet, like the resonance that travels rearward from a full-sized stereo speaker, sound is reflected back into the ear canal at reduced sound pressure levels. Surpassing federal Occupational Safety and Health Administration all-day listening standards, they only produce 75 dB at the inner ear. Ideal for wear in the office or when jogging, skiing, or working out, the anterior-ear design helps you to remain aware of your surroundings and prevents the earbuds from popping out. The earbuds play audio with the same clarity as conventional earbuds thanks to three interchangeable ear pads that provide full-range clarity, bass boosting, and surround sound. The 56" cord terminates in a standard 3.5 mm gold-plated stereo input jack. (3/4 oz.)
