## Long description

Koss PLUG are wired in-ear headphones designed for everyday listening, commuting and phone calls. These intraaural earphones deliver a declared frequency response of 10–20,000 Hz through a 1.2 m cable, providing a stable analog connection without the need for pairing or batteries. The model is available in a black and silver color scheme and is built to sit comfortably in the ear canal for extended use.
Advantages
The wired design ensures consistent audio transmission and immediate compatibility with devices that have a standard 3.5 mm jack or compatible adapter. A broad frequency range from 10 Hz to 20 kHz allows reproduction of low bass and high treble details within the limits of compact in-ear drivers. The 1.2 m cable length strikes a balance between mobility and unobtrusive cable management. The intraaural fitting offers passive noise isolation and a secure fit during daily activities.
Suitable for
Listening to music on smartphones, portable players and laptops
Hands-free phone calls and voice conversations
Commuting, travel and use on public transport
Casual gaming and video streaming

Cable length: 1.2 m

How to use
Insert the earbuds gently into the ear canal and adjust the position until you achieve a comfortable seal for better sound and passive isolation. Plug the connector into the device’s headphone jack or compatible adapter. Adjust playback volume from the connected device; avoid listening at high volume for extended periods to protect hearing. After use, wind the cable loosely to prevent kinks and store the headphones in a protective case if available.
Usage recommendations
For optimal sound and fit, try different ear tip sizes when available and ensure the cable is routed to minimise microphonics from clothing. Use a compatible adapter if your device lacks a 3.5 mm jack, and keep the connector and cable free from moisture and excessive strain to prolong product life.
