4. Setup and Installation
Replacing your hearing aid domes is a straightforward process. Always handle your hearing aid and domes with clean, dry hands to prevent damage or contamination.
- Remove the Old Dome: Gently grasp the old dome at its base and pull it straight off the receiver. Avoid twisting or pulling at an angle, which could damage the receiver.
- Inspect the Receiver: Check the receiver for any debris or damage. Ensure it is clean and clear before attaching a new dome.
- Attach the New Dome: Align the new Phonak Power Smokey Dome with the receiver. Push the dome firmly onto the receiver until it is securely seated. You should feel a slight click or resistance as it locks into place. Ensure the dome is fully attached and not loose.
- Verify Fit: Once attached, gently tug on the dome to confirm it is securely fastened.
If you experience difficulty or are unsure about the process, consult your audiologist or refer to your specific hearing aid's instruction manual.
5. Usage and Benefits
Phonak Power Smokey Domes are designed to enhance your hearing experience, particularly for those requiring significant sound amplification. Their unique design provides several benefits:
- Optimal Seal: The power dome design creates a full, secure seal within the ear canal. This minimizes sound leakage and feedback, ensuring that the amplified sound is directed effectively into your ear.
- Maximum Amplification: By preventing sound from escaping, these domes allow your hearing aid to deliver its maximum amplification potential, which is crucial for individuals with severe hearing loss.
- Reduced Sound Dissipation: The snug fit helps to retain sound within the ear, leading to a clearer and more consistent listening experience.
- Comfort: Made from non-allergenic silicone, these domes are soft and flexible, conforming comfortably to the ear canal for extended wear.

6. Maintenance
Regular maintenance of your Phonak Power Smokey Domes is crucial for hygiene, performance, and longevity. Domes should be cleaned and replaced periodically.
Cleaning:
- Gently wipe the domes with a soft, dry cloth daily to remove earwax and debris.
- For a more thorough cleaning, you may use a specialized hearing aid cleaning wipe or a slightly damp cloth (ensure no moisture enters the hearing aid receiver).
- Never use harsh chemicals, alcohol, or abrasive materials, as these can damage the silicone.
- Ensure domes are completely dry before reattaching them to your hearing aid.
Replacement:
Domes should be replaced regularly, typically every 2-4 weeks, or sooner if they become stiff, discolored, torn, or if sound quality diminishes. Regular replacement prevents earwax buildup from affecting performance and maintains hygiene.
7. Troubleshooting
If you experience issues with your hearing aid after replacing the domes, consider the following common troubleshooting steps:
- Poor Sound Quality or Feedback:
- Ensure the dome is securely attached to the receiver.
- Check if the dome is the correct size for your ear canal. An ill-fitting dome can cause sound leakage and whistling.
- Inspect the dome for any tears or damage. Replace if necessary.
- Clean the dome and receiver thoroughly to remove any earwax blockage.
- Discomfort or Irritation:
- Ensure you are using the correct dome size. A dome that is too large can cause pressure, while one that is too small may not provide a secure fit.
- Verify that the dome is clean and free of any foreign particles.
- If irritation persists, consult your audiologist.
- Dome Detaches Easily:
- Ensure the dome is pushed firmly onto the receiver until it clicks into place.
- Check the receiver for any damage that might prevent the dome from seating properly.
For issues related to the hearing aid itself, refer to your hearing aid's specific instruction manual or contact your audiologist.
