How to fix common problems with open-fit hearing aids

How to fix common problems with open-fit hearing aids

Use our troubleshooting guide if you’re having problems with one or both of your hearing aids. There might be a simple fix.

If these tips don’t work, or if you continue to have hearing aid problems, contact your audiologist.

If you’ve recently started using hearing aids, it’s normal for it to take a while to get used to the feeling of them in your ears and the sounds you hear. 

See our tips for adjusting to your hearing aids

Troubleshooting guide

What hearing aid problem do you have?

No sound or reduced sound quality

Is the battery fitted correctly?

You should see the positive (+) side when you open the battery drawer. If the battery is fitted correctly, try replacing it with a new one.

Is the tubing blocked or damaged?

Check for any obvious blockages or signs of damage. If there’s a blockage, detach the thin tube from the hearing aid and clean it using a wire cleaning tool.

Is there moisture in the tubing?

If you see condensation in the tubing, place a firm grip where the tubing attaches to the hearing aid and give it a few quick flicks to remove any droplets that might have collected.

If there’s often moisture in the tubing, you can buy condensation absorbing tablets to put in your hearing aid case overnight to absorb the condensation.

Buzzing noises

Is your hearing aid on the hearing loop (T) setting?

This can happen accidentally sometimes. To check if this is the problem, turn your hearing aid off and on to reset it.

Whistling noises

Does the earpiece fit firmly and securely inside your ear?

If there are gaps around the earpiece, the amplified sound can escape and cause a whistling sound that you or other people might hear.

Make sure you fit the earpiece in your ear canal as far as it will comfortably go.

If there are gaps around the earpiece, ask your audiologist for a larger or different shaped earpiece that fits snugly in your ear canal.

Is the hearing aid covered?

The microphones on your hearing aid will whistle if they are covered – for example, with a hat, scarf or headphones.

Is ear wax blocking the earpiece?

If it is, remove the wax by using a wire cleaning tool. This may stop the whistling.

If ear wax is blocking your ear, ask your GP where your nearest wax removal service is.

Is the tubing split or damaged?

This can happen at any time but is more likely to happen after 4 or 5 months of use. You can either replace the tubing yourself or get help from your audiologist.

Get help with hearing aid problems

If you’ve tried our troubleshooting tips and are still having problems with one or both of your hearing aids, your audiology service can help. 

You should also see an audiologist if: 

  • the tubing or earpiece is making your ear sore – this can easily be fixed 
  • you’ve worn hearing aids for a while and are not getting the same benefit from them – this might mean your hearing has changed and your audiologist needs to adjust your hearing aids. 

See your GP if you have ear pain, earache or discharge from your ear – you might have an ear infection that needs treating.

NHS hearing aid clinics 

If you have NHS hearing aids, you can get help with hearing aid problems at local hearing aid clinics. Contact your audiology service to find out where your nearest clinic is.

In some parts of the UK, RNID runs these clinics in partnership with audiology departments.
