Sennheiser PXC 250 II NoiseGard black

Closed, dynamic stereo mini headphones, great for traveling, outdoor activities, ideal for use with portable players (MP3, MP4, MD, CD...). Ultra-light coils provide high efficiency when using portable players.
The Sennheiser, one of the most respected headphones manufacturers, has equipped a unique NoiseGard noise suppression system. Thanks to active and passive damping, you can enjoy undisturbed listening even in a very noisy environment, such as in planes and similar background noise background environments. NoiseGard dampens frequencies below 1000 Hz up to -15 dB.
Registered design "Rotate and fold" allows you to rotate the earbuds by 90 degrees and fold the headphones into the closed position. The headphones are locked in open and closed positions.
The light weight, only 65 grams, makes it easy to carry. A kevlar-reinforced 1.8-meter long cable is finished with a 3.5 mm stereo jack connector. The NoiseGard (2 x AAA) system power cord, mounted on the cable, is equipped with a belt clip and can be rotated up to 360 degrees.
