The Koss UR29 are full-sized stereo headphones featuring a dynamic Mylar constructed driver element and anisotropic ferrite magnet structures to reduce distortion and deliver high volume with low-voltage devices. The headphones are designed with closed leatherette ear cushions to block out external noise and a padded adjustable headband for a comfortable fit. The earcups of the UR29 headphones can also be folded in to a compact package for convenient storage. The headphones have an 8 ft straight cord with an in-line volume control and 3.5mm gold-plated plug and come with a 6.3mm gold-plated adapter. Compared to Koss' UR40 stereophone the UR29 headphones have a higher impedance but lower-quality build than the UR40. They are also missing some of the additional features of the UR40 such as the screened earcups and a mesh sling.
