Signia hearing aids are popular for their slim design, clear speech and rechargeable convenience. Models built on the Integrated Xperience platform, such as the Pure Charge&Go IX, Styletto IX and Silk Charge&Go IX, are used by thousands of people across the USA. Even so, no hearing device is perfect. Earwax, moisture, a weak charge or a pairing glitch can make your aids go quiet, whistle or disconnect from your phone.
The good news is that most Signia hearing aids troubleshooting steps take only a few minutes at home. This guide covers the 15 most common problems and the fastest ways to fix them. If you are still choosing a pair, you can explore the full range of Signia hearing aids at HearUpUSA.

Quick Checklist Before You Start
These basics solve a surprising number of problems:
- Make sure the hearing aids are switched on.
- Check the charge level or battery.
- Wipe the microphone openings and the receiver.
- Check that the dome or earmold sits properly in your ear.
- Restart the hearing aids.
1. Signia Hearing Aid Not Working at All
Possible causes: low charge, dirty charging contacts, moisture, blocked receiver.
Fixes:
- Place both aids in the charger and check that the indicator shows charging.
- Leave them to charge fully before testing again.
- Wipe the hearing aid with a dry, soft cloth and check the receiver for wax.
If the aids still do not start, our hearing aid repair package can get them back in working order.
2. Signia Hearing Aid No Sound or Very Low Sound
This is the most common complaint, and earwax is usually the reason.
Fixes:
- Replace the wax filter (wax guard) following your user guide.
- Clean the dome or earmold tubing.
- Check the volume in the Signia app or on the hearing aid control.
- Make sure the active program is not a mute or streaming-only setting.
3. Signia Hearing Aid Whistling or Feedback
Whistling happens when amplified sound leaks out of the ear and gets picked up by the microphone again.
Fixes:
- Remove and re-insert the hearing aid so the dome sits snugly.
- Check for earwax buildup in your ear canal.
- Replace worn or loose domes.
- Keep hats, scarves and phone handsets away from your ears.
If the problem continues, the dome size or feedback settings may need adjustment. Our professional remote programming service can fine-tune your settings without a clinic visit.
4. Signia Hearing Aid Not Charging
Rechargeable models depend on a healthy charger. If you are thinking about switching to one, read more about rechargeable hearing aids.
Fixes:
- Check that the charger is plugged in and the cable is firmly connected.
- Clean the charging contacts on the aids and the charger with a dry cloth.
- Make sure each aid sits correctly in its slot.
- Try a different wall outlet or a certified USB adapter.
- Avoid charging in very hot or very cold places.
If the built-in battery no longer holds a charge after several years, a service visit is the safest option.
5. Signia Hearing Aid Battery Draining Too Fast
Common causes:
- Heavy Bluetooth streaming of calls, music and TV
- An older battery that has lost capacity
- A charger that is not making full contact
- Humidity or extreme temperatures
Tips: Charge the aids every night, switch them off or place them in the charger when not in use, and limit long streaming sessions on days when you need extra runtime.
6. Signia Hearing Aid Bluetooth Not Connecting
Fixes:
- Turn Bluetooth off and on again on your phone.
- Restart the hearing aids by placing them in the charger and taking them out.
- Remove the old pairing from your phone’s settings, then pair again.
- Update your phone’s operating system and the Signia app.
- Keep the phone close during pairing and avoid crowded wireless areas.
On an iPhone, pairing is done through Settings, Accessibility, then Hearing Devices. On Android, use the Bluetooth or hearing device section of your phone settings.
7. Signia App Not Working or Not Detecting Hearing Aids
- Update the app from the App Store or Google Play.
- Allow Bluetooth and any requested permissions.
- Close and reopen the app.
- Restart both the phone and the hearing aids.
- Reinstall the app if the issue remains.
8. Signia Hearing Aid Sounds Distorted or Muffled
- Clean the microphone openings and the receiver.
- Replace the wax filter and dome.
- Check for moisture and use a hearing aid dryer overnight.
- Switch to a different program and see if the sound improves.
If distortion continues, your hearing may have changed. Take a free online hearing test and have your aids reprogrammed if needed.
9. Signia Hearing Aid Cutting In and Out
Intermittent sound usually comes from moisture, a weak charge, dirty contacts or a damaged receiver wire.
Fixes: Dry the device, fully charge it, clean the contacts, and look at the receiver cable for cracks. If you see damage, do not pull on the wire. Have it replaced.
10. Signia Hearing Aid Feels Uncomfortable or Falls Out
- Try a different dome size (small, medium or large).
- Ask about a custom earmold for a more secure fit.
- Make sure the receiver wire sits flat against your head.
- Consider whether another style would suit you better, such as RIC, BTE or CIC.
11. Humming, Buzzing or Static Noise
- Move away from strong electronic or magnetic sources.
- Recharge the hearing aids fully.
- Clean the device and restart it.
- If the noise is constant, get it checked, as it may be a hardware fault.
12. Hearing Aids Affected by Moisture, Sweat or Rain
Many modern hearing aids resist moisture and dust, but they are not designed for swimming or showering.
What to do: Wipe them dry right away and leave them in a dehumidifier overnight. Never use a hair dryer, microwave or oven.
13. Accessories Not Pairing
Remote microphones, TV streamers and other accessories often need a fresh pairing. Switch the hearing aids off and on, then follow the accessory’s pairing steps. If you need a replacement, browse compatible hearing aid accessories.
14. Tinnitus or Ringing Seems Worse
If you notice new or louder ringing after wearing your hearing aids, the volume may be too high or the fit may be off. Lower the volume and speak to a hearing care professional. Tinnitus support settings can often be adjusted.
15. Hearing Aid Lost or Damaged
Check whether your warranty or damage coverage applies. HearUpUSA offers a 3-year warranty on hearing aids, and you can contact our team for help with repairs or replacements.
