Product information

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

Key specifications

Brand: Koss
Model: UR40 (MPN 183161, EAN 021299147801)
Type: Wired circumaural headphones, head-band style
Frequency response: 15–22,000 Hz
Cable length: 1.2 m (straight dual-entry 4 ft cord with dual plugs)
Ear cushions: Closed leatherette with screened ear cups (hybrid design)
Voice coils: Oxygen-free copper
Colour: Black, Silver

How to use

Connect the straight dual-entry cable to the appropriate audio outputs using the dual plugs. Place the head-band over your head so the circumaural ear cushions fully enclose each ear, ensuring a snug seal for optimal bass response while still allowing some ambient sound through the screened cups. 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.

Specifications

Microphone type: The characteristics of the microphone bulit into the device in terms of the reception of signals from all or just one direction, i.e. omnidirectional (better for concerts and the like vs unidirectional, more suitable for voice recording.: Not available
Ear coupling: Ear coupling describes the way in which headphones or earphones stay attached to, or inside, the ear. There are three common types of ear coupling: circumaural, supra-aural and intra-aural. Circumaural headphones enclose your ears with large pads that suppress external noise. Supra-aural headphones are typically more lightweight and sit on top of the ears with small pads. Intra-aural headphones come in two basic designs and neither style sits on the head itself. The first are ear buds, which sit just outside of the ear canal, on top of your ear lobes. The second type is actually inserted directly into the ear canal and offers some external noise suppression.: Circumaural
Connectivity technology: The technology that enables connectivity of the device, e.g. wired or wireless.: Wired
Recommended usage: What the product should be used for, and how it should be used (e.g. ambient temperature).: Music
Product type: The sub-category of the product.: Headphones

Headphones

Total Harmonic Distortion (THD): Total harmonic distortion is a measure of non-linear harmonic distortion and is given in %. Non-linear harmonic distortions are signals which were not present in the original before the signal was converted by the headphones. These unwanted signals are caused by the diaphragm, whose movements do not precisely move in time with the electric signals that cause it to move. Unfortunately, this is a feature of all electroacoustic transducers. Although it cannot be completely eliminated, suitable steps can be taken to minimise it. However, the user is not interested in why this distortion takes place but in how great the level of distortion must be for it to become perceptible. According to the findings of several research projects, a total harmonic distortion of 1% in the frequency range of 100 to 2000 Hz is imperceptible. Below 100 Hz, the perceptibility threshold lies at 10%.: 0.2 %
Headphone sensitivity:: 98 dB
Impedance: The effective resistance of an electric circuit or component to alternating current, arising from the combined effects of ohmic resistance and reactance.: 60 Ω
Headphone frequency: The range of frequencies (low to high sounds) that the headphones can produce.: 15 - 22000
