2. Start audio playback on your device.
3. Adjust the volume using your audio device's volume controls to a comfortable listening level.

5. Maintenance

Proper maintenance ensures the longevity and performance of your earphone.

5.1. Cleaning

• Ear Tips: Regularly remove the silicone ear tips and wash them with mild soap and water. Rinse thoroughly and allow them to dry completely before reattaching.
• Earphone Body: Wipe the earphone body with a soft, dry cloth. Do not use harsh chemicals or abrasive cleaners.
• Cable and Plug: Keep the cable and plug clean and free of dust.

5.2. Cable Care

The DMK-32 features a thin cable. To prevent damage:

• Avoid pulling the cable forcefully or subjecting it to sharp bends.
• Do not wrap the cable tightly around objects.
• When disconnecting, always pull the plug itself, not the cable.

5.3. Storage

When not in use, store the earphone in a clean, dry place, away from extreme temperatures and direct sunlight. Avoid tangling the cable.

6. Troubleshooting

If you encounter issues with your DMK-32 earphone, refer to the following common solutions:

• Test with Another Device: Connect the earphone to a different audio device to determine if the issue is with the earphone or the original device.
