The KRK KNS 8400 is a pair of stereo headphones that provide professional-quality audio in a compact and stylish design. Created to deliver the clarity of KRK studio monitors, the headphones have 40mm neodymium drivers to produce accurate, natural audio with a frequency response of 5 Hz to 23 kHz, as well as a wide dynamic range with low distortion. The headphones have an extended low-frequency response to ensure that your bass is accurately reproduced, while a transparent high-frequency reproduction results in accurate imaging.

Thick around-ear cushions are filled with special acoustic memory foam which offers excellent audio reproduction as well as up to 30 dB of noise isolation. They're also comfortable. The headband pads and ear cushions are easily replaceable.

The single-sided cable is made from oxygen-free copper to provide a high-quality signal path. It provides plenty of slack and is detachable for easy replacement. A detachable, inline volume control allows you to make quick adjustments to the listening level. The gold-plated 3.5mm stereo mini plug offers strain relief to ensure you won't cause the cable undue stress. The headphones come with a screw-on 1/4" adapter to provide wide compatibility with a variety of audio devices. The headphones have a foldable design and include a soft carrying case for convenient storage and travel.
