If your hearing aids have gone quiet, keep cutting out, won’t charge or refuse to pair with your phone, stay calm. Thousands of wearers face these issues every year, and most of them can be fixed at home in a few minutes.
This guide covers Resound hearing aids troubleshooting step by step. It applies to popular rechargeable and battery models, including the Vivia, Nexia, Omnia and Savi families. Work through the sections in order, and only move to the next one if the problem remains.
Quick Checklist Before You Start
Most problems come from five simple causes:
- Low or empty battery
- Earwax or debris blocking the sound outlet
- A dirty or damaged charger contact
- Moisture inside the device
- An outdated app or phone Bluetooth glitch
Keep a clean, dry cloth, a small cleaning brush and your user guide close by before you begin.
1. Resound Hearing Aid Not Working or No Sound
This is the most common complaint, and the cause is usually simple.
Step 1: Check the power. For rechargeable models, place the hearing aids in the charger and confirm the charging light responds. For disposable battery models, fit a fresh battery and wait about a minute after removing the sticker so it can activate.
Step 2: Check the volume and program. Press the button or open your app to confirm the volume is up and you haven’t switched to a quiet or streaming-only program by mistake.
Step 3: Clean the sound outlet. Wax is the number one cause of weak or dead hearing aids. Gently brush the microphone openings and the tip of the receiver. Replace the wax guard if it looks blocked, as shown in your user guide.
Step 4: Check the dome or earbud. A clogged or loose dome can muffle sound. Replace it if it looks worn, torn or stiff.
Step 5: Restart the devices. Turn them off, wait ten seconds and turn them on again. For rechargeable models, putting them in the charger and taking them out again usually restarts them.

2. Resound Hearing Aid Not Charging
A hearing aid that won’t charge is frustrating, but it is rarely a sign of permanent damage.
- Check the power source. Make sure the charger is plugged into a working outlet using the original cable and adapter.
- Clean the charging contacts. Wipe the contacts on both the hearing aids and the charger with a dry, soft cloth. Dust and skin oils can block charging.
- Seat the devices properly. Left and right aids should sit firmly in their slots. Check the charger light for the correct signal.
- Avoid extreme heat or cold. Charging in a hot car or on a cold windowsill can stop the process. Move the charger to a room-temperature spot.
- Try another outlet or cable. This quickly rules out a faulty power source.
If the charger light still doesn’t respond, the charger or battery may need professional service. Owners of the Resound Vivia range should check the user guide for the exact light patterns, as they differ slightly between models.
3. Resound Hearing Aid Whistling or Feedback
Whistling, also called feedback, happens when amplified sound leaks out of the ear and gets picked up again by the microphone.
Try these fixes:
- Reseat the hearing aid. Remove it and insert it again, making sure it sits snugly.
- Check for earwax. A blocked ear canal reflects sound back toward the microphone. If you suspect heavy wax, see a doctor or hearing professional rather than using cotton swabs.
- Inspect the dome size. A dome that is too small allows sound to leak. A different size or type can often stop the whistle.
- Keep hands and hats away. Cupping your hand near your ear or wearing a hat can trigger temporary feedback.
- Check for damage. Cracks in the casing or tubing can cause constant whistling.
If whistling continues after these steps, your device may need reprogramming, which can be done through a remote hearing aid programming session.
4. Resound Hearing Aid Bluetooth Not Connecting
Modern devices stream calls, music and TV audio directly to your ears, so a lost connection is easy to notice. Here is how to restore it.
Step 1: Update the basics. Make sure your phone’s operating system and the Resound Smart 3D app are on their latest versions.
Step 2: Turn Bluetooth off and on. Switch Bluetooth off on your phone, wait a few seconds and switch it on again.
Step 3: Restart your hearing aids. Turn them off and on, or place them in the charger and remove them.
Step 4: Remove and re-pair. On your phone, open the hearing device or Bluetooth settings, forget the hearing aids, then pair them again as shown in the app. On iPhone, look under Accessibility and Hearing Devices. On Android, open the Connected devices or Accessibility menu.
Step 5: Stay within range. Keep your phone within a few metres and avoid heavy interference from Wi-Fi routers or microwaves.
Some newer models also support Bluetooth LE Audio, which can improve connection stability on compatible phones. Check your device specifications to see if yours does.
5. Hearing Aids Cutting In and Out
Intermittent sound is often caused by moisture, a weak battery or a loose receiver connection.
- Dry the devices. Use a hearing aid dehumidifier or dry box overnight. Moisture from sweat, rain or humidity is a common cause of crackling and cut-outs.
- Check the receiver wire. On RIC and RIE styles, make sure the thin wire is firmly connected and free of cracks.
- Charge fully. A partly charged battery can cause unstable performance.
- Avoid heavy interference. Strong electromagnetic fields, such as near some machinery, can disrupt the signal for a moment.
6. Sound Is Distorted, Muffled or Too Quiet
When sound feels flat or distorted, think maintenance first:
- Clean the microphones and receiver tip.
- Replace the wax guard and dome.
- Check that you haven’t accidentally changed the program or volume in the app.
- Remember that your hearing can change over time. If the settings feel wrong even after cleaning, you may need a fresh programming adjustment.
7. How to Reset Resound Hearing Aids
A simple restart fixes many software glitches. For most models:
- Turn the hearing aids off, or place them in the charger.
- Wait at least ten seconds.
- Turn them on again, or remove them from the charger.
- Reconnect to your phone if needed.
A full factory reset or re-pairing is rarely required. If you try one, follow your user guide carefully, because a reset may remove your personal settings.
Daily Habits That Prevent Most Problems
A few minutes of daily care can prevent most faults:
- Wipe the hearing aids with a dry cloth every evening.
- Brush the microphone ports and sound outlets gently.
- Store them in a dry, cool place, ideally in a dehumidifier overnight.
- Replace domes and wax guards on schedule.
- Keep devices away from water, hairspray and heat.
- Charge them nightly if they are rechargeable.

When to Seek Professional Help
Stop troubleshooting and contact a professional if:
- The device was dropped in water or has visible damage
- You hear rattling inside the casing
- The hearing aid stays dead after cleaning and charging
- The charger light never turns on
- Your ears feel painful, itchy or blocked
Never open the casing yourself, as this can void your warranty.
Frequently Asked Questions
Why is my Resound hearing aid not working suddenly?
The most common causes are a low battery, blocked wax guard, moisture or a Bluetooth glitch. Charge the device, clean it and restart it first.
How long should rechargeable Resound hearing aids last each day?
Most rechargeable models are designed to last a full day on a full charge, though streaming and heavy use can shorten this. Check your specific model’s guide for exact figures.
Why do my hearing aids whistle when I wear a hat or hug someone?
Close objects reflect sound back into the microphone, which creates temporary feedback. This is normal, but constant whistling needs a fit or programming check.
Can I fix my hearing aids at home?
Cleaning, restarting, replacing domes and wax guards, and re-pairing Bluetooth are safe at home. Anything involving internal parts should be done by a professional.
Do hearing aids need to be reprogrammed?
Yes, periodically. Your hearing and comfort needs change, and fine-tuning helps keep sound clear.
