The flexible, transparent acoustic tube component of the earpiece is shown sealed in its individual plastic packaging, ready for assembly or replacement.

Maintenance and Care

Proper maintenance will extend the life of your earpiece:

• Cleaning: Regularly wipe down the earpiece cable and acoustic tube with a soft, damp cloth. For the acoustic tube and eartip, use mild soap and water, then rinse thoroughly and allow to air dry completely before reattaching.
• Storage: When not in use, store the earpiece in a clean, dry place, away from direct sunlight and extreme temperatures. Avoid tightly coiling the cable to prevent damage.
• Inspection: Periodically inspect the cable, plug, and acoustic tube for any signs of wear, kinks, or damage. Replace components if necessary to maintain optimal performance.

Troubleshooting

If you encounter issues with your earpiece, try the following solutions:

• No Audio:
  • Ensure the 3.5mm plug is fully inserted into the device's jack.
  • Check the volume level on your connected device.
  • Verify that the acoustic tube is securely attached and not blocked or kinked.
  • Test the earpiece with another compatible device if possible to rule out a device issue.
• Distorted Audio:
  • Reduce the volume on your connected device.
  • Ensure the acoustic tube and eartip are clean and free of debris.
  • Check for any visible damage to the cable or plug.
• Earpiece Falls Out:
