The HD-280 Pro is a closed-back, circumaural headphone designed for
professional-quality monitoring. Its exceptional attenuation of
environmental noise (up to 32 dB) makes it particularly useful for
use in high-noise environments, in outside broadcasts, and for DJs.
Featuring rugged design and optimum sensitivity, the HD-280 Pro
will deliver detailed and natural reproduction of music and speech
with a wide frequency response of 8 to 25,000 Hz (-10 dB).
Owing to its collapsible ear-pieces, the HD-280 Pro is highly compact when it comes to transportation. And all parts that are subject to wear and tear--such as earpads, headband padding, and the audio cord--are easily replaceable, ensuring long life. The headphone's 9-foot cord is detachable, so if it wears out you have only to replace the cord, not the headphone itself. The cord is made of oxygen-free copper for pure, long-lasting audio transmission.
