Operating Instructions

Basic Audio Playback

Once connected to your audio source, begin playback from your device. The KPH40 headphones will reproduce the audio. Adjust the volume directly from your audio source.

Detachable Cable System

The KPH40 features a detachable cable system, allowing you to interchange the standard 3.5mm utility cord with other compatible Koss Utility Series cables (sold separately), such as USB-C or Lightning cables. This provides flexibility for connecting to various devices without needing adapters.

To change cables, gently pull the 2.5mm connector from the headphone's junction. Then, connect the desired compatible utility cable following the steps outlined in the "Setup" section.

Maintenance

Cleaning

• Use a soft, dry cloth to wipe the earcups and headband.
• For the foam ear cushions, gently dab with a slightly damp cloth if necessary, and allow to air dry completely before use. Avoid excessive moisture.
• Do not use harsh chemicals, cleaning solvents, or strong detergents, as these may damage the headphone materials.

Storage

When not in use, store your headphones in a clean, dry place away from extreme temperatures and direct sunlight. Avoid tangling the cable by coiling it neatly.

Replacing Ear Cushions

The foam ear cushions are designed to be replaceable. If they become worn or damaged, new cushions can be purchased from authorized Koss retailers. To replace:

1. Gently peel off the old ear cushion from the earcup.
2. Align the new ear cushion with the earcup and carefully stretch it around the edge until it is securely fitted.
