Maintenance

Cleaning

Regular cleaning ensures optimal performance and longevity of your hearing aids. Use the provided cleaning brush to gently remove any earwax or debris from the ear tips and sound holes.

Water Resistance

The Diamond X1 hearing aids are rated IPX5 for water and dust resistance. This means they are protected against low-pressure water jets from any direction, making them suitable for use during light rain or sweating. However, they are not designed for swimming or showering.

Troubleshooting

• No Sound/Low Volume: Check battery levels of both hearing aids and charging case. Ensure ear tips are clean and properly fitted. Adjust volume via the app or physical buttons.
• App Connectivity Issues: Ensure Bluetooth is enabled on your smartphone. Try restarting the app or reinstalling it if persistent issues occur.
• Feedback/Whistling: Ensure ear tips are correctly seated and form a tight seal in the ear canal. Try a different size or style of ear tip.
• Sound Delay/Echo: This can sometimes occur if one ear is not experiencing hearing loss or if settings are not balanced. Adjust individual ear settings via the app or consult support.
