Lexie B2 Powered by Bose hearing aids are a popular over-the-counter (OTC) hearing aid option for individuals with mild to moderate hearing loss. They are designed to deliver clear, reliable sound and a comfortable listening experience. However, like all hearing aids, they may occasionally encounter performance issues. Common problems include feedback or whistling, poor sound quality, difficulty with volume control, and Bluetooth connectivity issues. This guide provides practical tips to troubleshoot and fix these issues before seeking professional repair.
1. Poor Sound Quality
If your Lexie B2 hearing aids sound muffled, distorted, or unclear, start with these steps:
- Check that the hearing aids are clean and free of wax or debris.
- Replace the wax guards if clogged.
- In a quiet room, open the Lexie app and run a new hearing test to recalibrate sound settings.
- If sound issues persist, contact Lexie customer support via the app.
2. Feedback or Whistling
Feedback happens when amplified sound re-enters the microphone. To reduce or eliminate whistling:
- Reposition the hearing aid for a more secure fit.
- Switch to a closed dome for better sound sealing.
- Ensure the dome is the correct size for your ear canal.
- Check for cracks or gaps in the tubing or receiver.
3. Difficulty with Volume Control
If your Lexie hearing aid buttons aren’t working:
- Inspect for debris or wax around the push buttons.
- Check for moisture damage and dry the aids if needed.
- Try adjusting the volume through the Lexie app as an alternative.
- If the issue persists, contact Lexie support or a hearing care provider.
4. Bluetooth or Connectivity Issues
- Ensure the hearing aids are paired correctly with the app.
- Restart your phone and the hearing aids.
- Forget and re-pair the hearing aids in Bluetooth settings.
- Place the hearing aids in their charger, then remove to reset.
5. Distorted Sound
Distortion may be caused by earwax blockage, damaged components, or a loose fit. Try:
- Cleaning the hearing aid and dome.
- Replacing the wax guard.
- Inspecting the receiver and replacing it if necessary (guide here).
6. iPhone Call Streaming Problems
If calls are not streaming to your iPhone:
- Check if your hearing aids require a firmware update (devices purchased before May 2023 likely do).
- Delete and re-pair the hearing aids via the app.
- Restart your phone and hearing aids before pairing again.
Conclusion
Lexie B2 Powered by Bose hearing aids are an excellent choice for many users, but like all hearing devices, they may need occasional troubleshooting. By following these steps for cleaning, maintenance, and resetting, you can often fix common issues yourself. For persistent problems, consult an audiologist or contact Lexie customer service for assistance.
