Sennheiser CX 6 High Fidelity Sound Earbuds with Noise Reduction - Old Version

Eliminate up to 90% of fatiguing cabin noise on your next flight in a sleek, compact footprint. Sennheiser's CX 6 Travel offers exceptional customized noise isolation, rich, detailed sound and accessories that make travel a breeze. The discreet design of the CX 6 means no cumbersome cable tangles and easy on/off for in-flight announcements. The CX 6 stores quickly and safely in the included carrying case. Included is an airline adapter for connection to your favorite airline's entertainment console. Painstaking effort was made to measure optimum cable lengths and ear adapter sizes to ensure an ergonomic, simple use with no cable-tangling-hassle. The adapter also doubles as an impedance switch, making the CX 6 compatible with low output devices like today's MP3 players, as well as high output devices such as airline consoles, headphone amps and hi-fi equipment.
