The CX 300 black are high-quality stereo ear-canal headphones with powerful, bass-driven stereo sound for listening 'on the move'. Ear adapters in three different sizes ensure a perfect fit, high wearing comfort and an excellent attenuation of ambient noise. The CX 300 are ideal for use with MP3, CD, MD, or DVD players and many other portable devices.
Note: The longer side of the asymmetrical cable goes behind the neck and into the opposite ear. This mimics a single sided cable and reduces the amount of cable in front of the wearer during physical activity. This is a safety and ergonomic feature.
