Protect Your Hearing Aids from Condensation


For those who live in the North, the cold winter weather can present another challenge for hearing aids wearers.  We all know not to get your hearing aid wet with water. However, what about cold weather? Protecting your hearing aids from condensation is vitally important.

Studies have shown that the cold itself is surprisingly not damaging. However, the condensation that occurs from temperature changes can adversely affect your hearing aid.

For those of us who wear eyeglasses, removing the moisture or condensation from the lenses after coming indoors from the extreme cold is an all too common occurrence.  The same condition occurs with hearing aids. However, removing that inside moisture is not possible and will eventually lead to permanent damage.

Protecting your Hearing Aids from Condensation Damage

Moisture can cause corrosion to the delicate internal digital circuitry of the hearing aid as well as the battery and battery contacts. Condensation can soak into the diaphragms and damage the tiny microphones and speakers.  Moisture droplets commonly plug the very small diameter sound tubing and must be cleared out.


  • You might notice that sounds fade in and out
  • Scratchy sound
  • Distorted or unclear sound
  • The unit may completely stop working and in a few hours start again when the moisture droplet obstructing the tubing evaporates over time.


While moisture is hard to avoid in extreme cold, there are some precautions you can take in an attempt to keep your hearing aids dry and safe.

  • Open the battery door at bedtime allowing the moisture to evaporate.
  • Hearing aid dehumidifier: This is a small inexpensive device that contains a silica crystal desiccant. The desiccant will absorb moisture from the hearing aid overnight. You can dry and reactivate silica crystals by placing them inside an oven or microwave.
  • Hearing aid Sweatband or Sweat sock

Although hearing amplifiers have many benefits, they are still susceptible to damage from moisture like other hearing aids. Otofonix is dedicated to providing the best ear amplifier as well as education lacking in the industry.

Sound Environment Settings
Programs or environmental settings that allow you to optimize performance for noisy, quiet, or social situations
Digital Sound Processor
All Otofonix Hearing Aids are 100% Digital because they all use a DSP Chip. Without a DSP, noise-canceling is not possible.
Noise Canceling
Uses a digital algorithm to reduce background noise more effectively in noisy and challenging environments.
Directional Microphone
Makes it easier to focus on sounds coming from in front of you, and allows for more advanced and effective noise cancellation
A telecoil acts as a receiving antenna for your hearing aids. When you connect with a sound system of a theater or church, you get amplified sounds delivered directly into your hearing aids. So no matter where you are in the theater, you automatically have the best seat in the house. Only the sound from the hearing loop's microphone is amplified, while background noise is shut out.
Wear your device all day and charge when you go to bed. No need to handle tiny hearing aid batteries
Smartphone Compatible
Adjust your Otofonix Bluetooth Hearing Aid with your smartphone via the Otofonix App. No need to draw attention to your hearing aid; you can adjust it by using only your phone.
Personalized Hearing
Using the Otofonix App, you can customize your hearing aid to meet your unique hearing loss profile. It's like having an audiologist in your living room.
