3.2 Selecting and Installing Ear Tips

Proper ear tip selection is crucial for sound quality and comfort. Experiment with the included silicone ear tips to find the best fit for your ears.

1. Gently remove any pre-installed ear tips from the earphone nozzle.
2. Choose a pair of ear tips that feel comfortable and create a good seal in your ear canal. A good seal is essential for optimal bass response and passive noise isolation.
3. Carefully push the chosen ear tip onto the earphone nozzle until it is firmly attached.

5. Maintenance and Care

• Cleaning: Regularly clean the ear tips with a soft, damp cloth. For the earphone nozzles, gently wipe away any earwax or debris using a small brush or cotton swab. Ensure the nozzles are dry before reattaching ear tips.
• Cable Care: Avoid sharp bends or excessive pulling on the cable to prevent damage. When not in use, coil the cable loosely and store it in a protective pouch or case.
• Storage: Store your earphones in a clean, dry place away from extreme temperatures and direct sunlight.
• Detachable Cable: If you need to detach the cable, pull directly on the connector housing, not the cable itself, to avoid damaging the pins.

6. Troubleshooting

• No Sound or Low Volume:
  • Ensure the 3.5mm jack is fully inserted into the audio source.
  • Check the volume level on your audio source.
  • Verify that the detachable 2-pin cable connectors are securely attached to the earphones.
  • Test with a different audio source or cable if possible to rule out component failure.
• Unbalanced Sound (One side quieter):
  • Check the ear tip fit on both earphones. An improper seal can affect sound balance.
  • Inspect the earphone nozzles for any blockages (e.g., earwax). Clean if necessary.
  • Ensure the cable is correctly connected to the left and right units.
• Poor Fit or Discomfort:
  • Experiment with different sizes and types of ear tips provided to find the most comfortable and secure fit.
  • Adjust the cable routing over your ears to optimize comfort.
