Product Description

The UR40 delivers digital quality sound in an ultra-lightweight design for listeners on-the-go. The UR40 features dynamic elements for a wide frequency response from 15-22,000 Hz. A 2 mil. titanium coating on its diaphragms increases the rigidity of the elements, minimizing mechanical distortion and ensuring exceedingly accurate sound reproduction. Computer-optimized neodymium iron boron rare earth magnet structures enable the UR40 to deliver greater volume, even with low-voltage portable devices. Oxygen-free copper voice coils improve signal transmission and conduction for cleaner, clearer sound. With its hybrid design, the UR40 combines the best of closed-style and open-style headphones. Closed leatherette earcushions form a light seal around the ears, enhancing bass frequencies. Screened earcups provide an open, hear-through sound that lets listeners stay in touch with the world around them. The result is a full frequency, clean sound that turns any recording into a “live” performance.At just over six ounces the UR40 wears comfortably even after hours of continuous listening. The airy mesh sling provides soft breathable support, ideal for those with touch-sensitive scalps. An adjustable headband accommodates all head shapes and sizes for maximum comfort. When not in use, the resilient, lightweight frame folds into a compact configuration that’s protective, easy to carry and convenient to store. Perfect for travel, the UR40 includes a straight dual-entry eight foot cord. A gold-flashed 3.5mm (1/8″) plug, L-shaped to minimize cord stress is included.The UR40 will delight listeners seeking heavyweight sound in a comfortable lightweight package.
Home and portable audio take on fresh life with quality headphones, and Koss’s lightweight, closed-ear UR40 is designed to keep outside noises out and headphone sound in–perfect for use in busses and libraries alike. With its extended frequency range of 15 to 22,000 Hz, you’ll never miss a single bass note or want for high-frequency splash or shimmer.

The UR40’s titanium driver elements ensure taut low end and clear treble, while its collapsible headband design further lends it to portable applications and protects the headphone when not in use. The headphone comes with a four-foot, dual-entry cord and a .25-inch stereo adapter for use with hi-fi components.
