The Koss UR18 headphones are designed for comfort and sound quality. They feature large, comfortable earcups with soft leatherette cushions that provide a light seal for enhanced bass. The adjustable headband allows for a personalized and secure fit, ensuring comfort during extended listening sessions. The durable, wired connection ensures reliable audio transmission to your device.
1. Setup
1.1 Connecting Your Headphones
To begin using your Koss UR18 headphones, locate the 3.5mm audio jack at the end of the headphone cable. Insert this jack firmly into the corresponding audio output port on your audio device (e.g., smartphone, tablet, computer, MP3 player, stereo system). Ensure the connection is secure to prevent audio interruptions.
1.2 Adjusting for Comfort
The UR18 headphones feature an adjustable headband. Gently slide the earcups up or down along the headband until they rest comfortably over your ears. The earcups should fully enclose your ears to provide optimal sound isolation and bass response. Adjust the headband symmetrically for balanced pressure.
2. Operating Instructions
2.1 Basic Audio Playback
Once connected to your audio source, begin playing audio from your device. The volume is controlled directly from your connected device. Start with a low volume level and gradually increase it to a comfortable listening level. Avoid excessively high volumes to protect your hearing.
2.2 Proper Wearing
For the best audio experience and comfort, ensure the earcups are positioned correctly over your ears. The closed leatherette ear cushions are designed to create a seal, which is crucial for enhancing bass frequencies and minimizing external noise.
3. Maintenance and Care
3.1 Cleaning Your Headphones
To maintain the longevity and hygiene of your Koss UR18 headphones, regularly clean the ear cushions and headband. Use a soft, dry, lint-free cloth to wipe down the surfaces. For stubborn dirt, a slightly damp cloth with mild soap can be used, but ensure no moisture enters the speaker grilles or electronic components. Allow to air dry completely before use.
3.2 Storage
When not in use, store your headphones in a clean, dry place away from extreme temperatures, direct sunlight, and excessive dust. Avoid wrapping the cable too tightly around the headphones to prevent damage to the internal wiring.
3.3 Cable Care
The headphone cable is durable but can be damaged by excessive pulling or sharp bends. Always grasp the plug when disconnecting from a device, rather than pulling on the cable itself. Avoid placing heavy objects on the cable.
4. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No sound from headphones. | Headphone jack not fully inserted. Audio source volume too low or muted. Incorrect audio output selected on device. Faulty cable or headphones. | Ensure the 3.5mm jack is fully inserted into the audio port. Increase the volume on your audio device. Check your device's audio settings to ensure output is directed to the headphone jack. Test with another audio device or another pair of headphones to isolate the issue. |
| Sound is distorted or unclear. | Volume too high. Poor connection. Audio file quality. | Reduce the volume on your audio device. Re-insert the headphone jack. Try playing a different audio file or source to determine if the issue is with the content. |
