## Summary description

The Koss UR40 headphones offer a wired connection and are designed for music enthusiasts. With a frequency range of 15 - 22000 Hz, they deliver clear and rich sound. The 1.2 m cable provides flexibility and ease of use. Available in stylish black and silver colors, these headphones combine comfort with quality performance.

## Long description

The Koss UR40 headphones combine heavyweight sound intensity with an ultra-lightweight, collapsible design for convenient on-the-go listening. These wired circumaural headphones deliver a wide frequency range (15–22,000 Hz) and use improved signal transmission and oxygen-free copper voice coils to reduce mechanical distortion and provide clear, accurate sound reproduction. Closed leatherette ear cushions form a seal around the ears while screened ear cups allow some ambient audio, creating a hybrid closed/open listening experience that preserves bass impact and maintains awareness of surroundings. The 1.2 m straight dual-entry cable with dual plugs and the head-band wearing style make the UR40 suitable for a variety of everyday listening situations.
Advantages
The hybrid design balances bass enhancement from closed leatherette cushions with an open, hear-through character from screened ear cups, producing a full, natural sound. Lightweight construction (just over six ounces) and a collapsible frame make the UR40 easy to wear, store and transport. Oxygen-free copper voice coils and an extended 15–22,000 Hz frequency response contribute to reduced distortion and precise audio reproduction. The wired 1.2 m cable with dual plugs provides a reliable connection for compatible audio equipment.
Suitable for (tasks / use cases)
 Listening to music on portable players and home audio systems
 Everyday commuting and travel where awareness of surroundings is desired
 Casual monitoring and playback for music enthusiasts
 Storage in backpacks or carry bags due to collapsible design

Adjust the head-band for a comfortable fit. When not in use, fold the headphones along the collapsible joints for compact storage.
Usage recommendations
For best long-term performance, avoid exposing the headphones to excessive moisture or high temperatures, coil the cable loosely to prevent kinks, and store the UR40 in a protective bag when transporting. Use compatible audio sources and moderate volume levels to reduce the risk of hearing fatigue.
