4. Operating Instructions

4.1 Basic Audio Playback

Connect the 3.5mm jack of the earphone cable to your audio source (smartphone, tablet, computer, etc.). Adjust the volume on your device to a comfortable listening level before placing the earphones in your ears.

4.2 Media Control (if applicable)

If your cable includes an inline remote, you can control media playback and calls:

• Short Press: Answer/End Call, Play/Pause Music
• Press Twice: Next Song
• Press Three Times: Previous Song
• Long Press: Reject Call

Note: Functionality may vary depending on your connected device and operating system.

5. Maintenance and Care

• Cleaning: Regularly clean the eartips with a soft, damp cloth. Ensure no moisture enters the earphone drivers.
• Cable Care: The detachable cable is designed for durability. Avoid sharp bends or excessive pulling. When detaching, pull directly on the connector, not the cable itself.
• Storage: When not in use, store your earphones in a clean, dry place, preferably in a protective case, to prevent tangling and damage.
• Water Resistance: The earphones are rated as waterproof. However, avoid prolonged submersion or exposure to high-pressure water. Dry thoroughly if exposed to moisture.

6. Troubleshooting

6.1 No Sound or Low Volume

• Ensure the 3.5mm jack is fully inserted into your audio device.
• Check the volume level on your audio device.
• Verify that the earphone cable is securely connected to both earphones.
• Test with another audio source or another pair of headphones to isolate the issue.

6.2 Poor Sound Quality (Distortion, Lack of Bass)

• Ensure the eartips provide a proper seal in your ear canal. Try different sizes.
• Check for debris or earwax buildup in the earphone nozzles. Clean carefully if necessary.
• Some users report a faint 'snow' or static sound when no audio is playing or at very low volumes. This is a characteristic of some high-sensitivity earphones and is typically masked by audio playback.

6.3 Earphones Falling Out

• Ensure you are using the correct eartip size for a snug fit.
• Confirm the cable is routed over your ear correctly, utilizing the ear hook design for stability.
