Water and sweat can affect hearing aids in everyday situations, such as exercise, outdoor activities, sudden rain, or humid climates. Even when devices don’t appear visibly wet, moisture can still build up inside the hearing aid, reducing sound clarity, damaging sensitive components, and shortening the device’s lifespan if it isn’t properly protected against water and sweat.
In this article, we’ll cover what water-resistant and sweat-proof hearing aids are and why moisture protection matters. We’ll also share the best water-resistant and sweat-proof hearing aids, along with practical tips on how to safeguard your devices during exercise and humid conditions, and how to choose hearing aids designed to handle everyday moisture.

What Are Water-Resistant and Sweat-Proof Hearing Aids?
No hearing aid is truly waterproof, but many are engineered to resist moisture from sweat, humidity, and rain. Such moisture protection is essential for maintaining long-term sound quality and ensuring device reliability.
Hearing aids with moisture protection can be described as either water-resistant or sweat-proof. Water-resistant hearing aids use sealed casings, nano coatings, and internal barriers to reduce the risk of moisture damage. Similarly, sweat-proof hearing aids are designed specifically for body-worn use during exercise and daily activity.
Why Do I Need Water-Resistant or Sweat-Proof Hearing Aids?
Exposure to moisture is among the most common causes of hearing aid malfunction and long-term performance issues. Water-resistant hearing aid designs help reduce this risk by limiting moisture entry and protecting sensitive electronic components. This translates to greater durability, clearer sound quality, and a more seamless fit into your lifestyle.
Greater durability
Sweat and water can accelerate corrosion in battery contacts and internal components. Protective designs help prevent this damage, ensuring your hearing aids remain durable over time.
Consistently clear sound
Moisture can affect microphones and receivers, leading to distortion, static, or reduced clarity. Water-resistant features ensure more reliable sound quality, so your hearing aids perform consistently.
Stress-free wear
With effective moisture protection, you can wear your hearing aids during exercise, outdoor activities, or in humid climates without worrying about sudden malfunctions. This ensures a more seamless fit into your active lifestyle.
How Do I Know if My Hearing Aids Are Water-Resistant or Sweat-Proof?
IP stands for Ingress Protection, an international standard that indicates how well devices resist dust and liquids. The first digit refers to dust protection, while the second measures resistance to water or moisture. Higher numbers indicate stronger protection, which is ideal for water-resistant and sweat-proof devices.
How to choose water-resistant and sweat-proof hearing aids
When selecting hearing aids, it helps to know the common IP ratings relevant to exercise and water exposure:
- IPX4: Resistant to splashes and suitable for light workouts
- IPX5: Handles heavier sweating and more intense activity
- IP67: Can tolerate temporary water exposure
- IP68: Suitable for high humidity, rain, and intense exercise (all Oticon hearing aids have an IP68 rating)
For the best protection, consider hearing aids with IP67 or IP68 ratings. Additionally, look for features like sealed microphones and receivers, which are critical for sweat-proofing.
You may also want to opt for rechargeable models, which reduce moisture exposure from battery changes. If you actively exercise, behind-the-ear or receiver-in-canal styles with sports locks are recommended to prevent the hearing aid from shifting and coming into contact with sweat.

How to Protect Hearing Aids Against Water and Sweat
Even water-resistant and sweat-proof hearing aids can be affected by moisture if not properly cared for. By taking a few simple precautions during and after exercise, you can help maintain optimal performance, extend the lifespan of your devices, and ensure they continue delivering clear, reliable sound.
During exercise
To reduce moisture exposure during activity:
- Use sweat covers or moisture guards for added protection
- Wear sweatbands or caps to protect your hearing aids from direct contact with sweat
- Secure hearing aids with retention clips or sports locks to prevent shifting or falling, so your device does not come into contact with sweat
After exercise
Proper post-activity care is just as important. Here’s what you can do:
- Wipe hearing aids immediately after exercise to remove sweat
- Use a soft, dry cloth to clean residues before corrosion can start
- Allow hearing aids to air dry fully before storage or charging
FAQs About Water-Resistant and Sweat-Proof Hearing Aids
Can hearing aids be worn in the water?
Most modern hearing aids are water-resistant but not completely waterproof. This means they can handle the occasional splash, light rain or brief accidental contact with water, but they are not designed for swimming or prolonged submersion.
As a general rule, you should avoid wearing hearing aids during water activities such as swimming, water sports or showering. Chlorinated pool water and seawater are especially damaging, as they can accelerate corrosion of internal components.
Which hearing aids are the most sweat-resistant?
Hearing aids with IP68 ratings offer the highest level of protection currently available. In fact, all Oticon hearing aids have an IP68 rating, combining strong moisture resistance with advanced sound processing and long-term reliability.
Can hearing aids be used in a sauna?
Hearing aids should not be worn in a sauna, even if they are described as waterproof or water-resistant. The combination of extreme heat and high humidity can damage internal components and affect sound performance. It’s best to remove your hearing aids before entering a sauna and store them in a safe, cool, and dry place.
What if my hearing aids fall into water?
If your hearing aids fall into water, first shake the device carefully to remove any visible moisture. Avoid using hairdryers, radiators, or direct heat, as this can damage internal components.
For hearing aids that use disposable batteries, open the battery compartment right away and remove the battery. Leave the battery door open and place the hearing aids on a dry surface to air-dry. Moisture can corrode battery contacts and affect sound quality if not addressed promptly.
For rechargeable hearing aids, switch the device off. Use a hearing aid dryer or gently dry the hearing aid with a towel and leave it in a dry, well-ventilated area until completely dry. Once fully dry, it can be returned to the charger.
Finally, switch on the hearing aid and check that the sound is clear and functioning properly. If the sound seems muffled or there is no sound, contact your hearing care professional for further assistance.
What are some warning signs of moisture damage in my hearing aids?
Even water-resistant hearing aids can be affected by excessive moisture. Watch for common signs of moisture damage, including:
- Crackling or static sounds
- Muffled or distorted audio
- Sudden power interruptions
Noticing these warning signs early is important, as timely maintenance can help prevent long-term damage and keep your hearing aids performing at their best.
