The UR40 stereo headphones from Koss provide high-quality sound in a lightweight design. The headphones are collapsible, ideal for travel. The headphones feature dynamic drivers with titanium-coated diaphragms to minimize distortion and provide exceptionally accurate sound reproduction. NdFeB magnet structures deliver high volume levels, even from low-power sound sources, while OFC voice coils improve conductivity for clean, clear sound.

The self-adjusting headband accommodates virtually any head size, while the around-ear leatherette cushions create a seal around the ear for terrific comfort and bass response. The open-back earcups provide a hear-through sound that provides natural audio and allows you to hear your environment. The attached cable is 4' long to provide plenty of slack, and has a gold-plated 3.5mm stereo mini plug to provide wide compatibility with MP3 players, CD players, and more. The plug is angled to provide strain relief.
