Phonak Sphere Hearing Aid Troubleshooting Guide
Phonak Sphere devices are among the most advanced hearing aids available, offering exceptional sound quality and seamless Bluetooth connectivity. However, like all technology, occasional issues can arise. This guide will walk you through common problems and their solutions, covering sound, charging, and connectivity issues.
1. Sound and Audio Issues
No Sound or Very Low Volume
Ensure the hearing aid is powered on.
Check for earwax blockages in the dome or receiver and clean if necessary.
Inspect and replace the wax guard if it appears clogged.
Confirm the volume setting using the app or device controls.
Try a different program setting via the app.
Distorted or Crackling Sound
Clean the microphone and receiver openings with a soft brush.
Check for moisture buildup; consider using a hearing aid dryer.
Ensure the receiver wire is not damaged or loose.
Whistling or Feedback
Make sure the dome or mould is fully inserted into the ear canal.
Consider changing to a more occlusive dome if feedback persists.
Verify that the hearing aid is fitted correctly and not too loose.
2. Charging and Power Issues
Phonak Sphere aids use rechargeable lithium-ion batteries.
Not Charging or No Lights
Confirm the charger is connected to a working power source.
Reinsert the hearing aids into the charger until the indicator lights turn on.
Gently clean the contact points on both the aids and the charger.
Use a different USB cable or power adapter to test functionality.
Battery Draining Quickly
Ensure the aids are fully charged (3+ hours) before use.
Limit excessive streaming or Bluetooth use if battery life is reduced.
Check for firmware updates using the Phonak app.
3. Bluetooth and App Connectivity
Phonak Sphere connects via the myPhonak app for adjustments and streaming.
Connection Issues
Toggle Bluetooth off and back on.
Restart your hearing aids by placing them in the charger momentarily.
Forget the device in your phone’s Bluetooth settings and re-pair.
Audio Streaming Problems
Ensure both hearing aids are connected individually in your Bluetooth settings.
Close unused apps that may interfere with Bluetooth.
Restart your phone and relaunch the app.
App Not Responding
Make sure the app is updated to the latest version.
Check that Bluetooth and location permissions are enabled.
Reinstall the app if persistent issues occur.
