Article Summary: Hearing aids usually last 3 to 5 years, but lifespan depends on the device quality, hearing aid style, daily use, moisture, sweat, earwax, cleaning habits, and professional maintenance. Regular cleaning, drying, careful storage, battery care, and audiologist checkups can help hearing aids last longer. Signs it may be time to replace them include weak battery life, frequent repairs, and hearing aids that no longer help as well as they used to.

If you’re a person who relies on hearing aids, you’ve probably wondered, ‘how long do hearing aids last?’
On average, hearing aids last between three to five years. However, a wide range of factors can influence this lifespan, from the technology inside the device to how frequently you produce sweat and earwax. (Professional ear cleaning will help reduce wax buildup in both your ears and your hearing aids.) Accounting for these wide ranging factors, other industry stats cite a mean of around 5-7 years.

This guide explains the factors that influence hearing aid longevity, including how to care for your devices and when it might be time to upgrade. You can also learn how to make the most of your hearing aid investment with the seasoned audiologists at Better Hearing Clinic.
Why Do Hearing Aid Lifespans Vary?
Factors That Affect How Long Hearing Aids Last
| Factor | How It Affects Hearing Aid Lifespan |
|---|---|
| Quality of Materials and Technology | Premium materials may resist dust and water better, while advanced features like Bluetooth and noise cancellation add more technology that can eventually wear or fail. |
| Maintenance and Cleaning | Moisture, dust, earwax, sweat, and skin oils can build up over time. Daily cleaning and professional service every three to four months can help extend device life. |
| Usage Frequency | Hearing aids used every day experience more wear and tear, especially in dusty workplaces or humid environments. |
| Body Physiology | People who produce more earwax, perspire heavily, or have certain ear conditions may need more frequent cleaning, repairs, or replacement. |
| Type of Battery and Hearing Device | Behind-the-ear devices may last longer for some people than in-the-ear models because ITE hearing aids sit inside the ear canal and are exposed to more moisture and earwax. |
| Changing Technology and Hearing Needs | Older models may become outdated after five to 10 years, and changes in hearing may require stronger amplification or newer features. |
No two people are exactly the same, and neither are their hearing aids. This is due to a number of influences, both in terms of the device and the owner’s habits.
Here’s why:
1. Quality of Materials and Technology
The durability of your hearing aids largely depends on the materials and technology.
For example, devices made with premium-grade materials are more resistant to dust and water and typically last longer.
In contrast, modern, high-tech hearing aids integrate features like Bluetooth and noise cancellation, which increase the number of things that could go wrong.
2. Maintenance and Cleaning
Regular maintenance plays a huge role in determining how long your hearing aids will last. Hearing aids are exposed to moisture, dust, earwax, sweat, and skin oils, all of which can build up over time. Without proper cleaning, these residues can cause damage to the device’s delicate components.
Quick Tip: Keep your devices dry by using a dehumidifier or desiccant cup at night to protect against moisture damage. Frequent cleaning at home and professional service every three to four months can significantly extend a hearing aid’s life.
3. Usage Frequency
Hearing aids used every day will inevitably experience more wear and tear. People with hearing aids should also consider how their environments (e.g., dusty workplaces or humid climates) might affect the device.
4. Body Physiology
Every individual will affect hearing aids in different ways. For instance, people who generate more earwax or perspire heavily may need repairs and replacements more frequently. If you have (or are prone to) internal ear conditions, you must clean your hearing aids even more frequently to avoid damaging the device.
5. Type of Battery and Hearing Device
Hearing aid style also plays a big role. Standard wisdom in the hearing aid industry suggests that behind-the-ear (BTE) devices may last longer for some people than in-the-ear (ITE) devices. This is because ITE models sit directly in the ear canal, exposing more internal electronic components to moisture and earwax.
Keep in mind that advancements in technology—such as internal nanocoatings—are slowly closing this gap.
Hearing aid batteries are essential for keeping your hearing aids functional. They provide the power needed for the device to amplify sounds, helping you hear more clearly. To get the best performance from your hearing aids, it’s important to replace the batteries before they lose power completely.
The lifespan of hearing aid batteries varies depending on the type of hearing aid, battery size, and usage. Disposable batteries typically last 20 days, while rechargeable batteries usually provide a full day of use on a single charge.
6. Changing Technology and Needs
Hearing aid manufacturers continually release new hearing aid models equipped with advanced features to address evolving needs, often making older models obsolete after five to 10 years. Additionally, your own hearing can change over time, requiring devices with more powerful amplification or additional features like tinnitus masking. (Source.)
How to Extend the Life of Your Hearing Aids
Even though no hearing aid will last forever, there are plenty of ways to extend its usable life.
Here are some ways to maximize the value of your hearing aids.
How to Extend the Life of Your Hearing Aids
| Care Step | What the Article Recommends |
|---|---|
| Follow a Regular Cleaning Routine | Wipe hearing aids daily with a soft, dry cloth and remove wax or debris with a cleaning tool or brush. |
| Schedule Professional Maintenance | See an audiologist for regular service, including filter changes, tubing cleaning, and microphone or speaker checks. |
| Manage Moisture Exposure | Use a hearing aid dehumidifier or drying station and remove devices before activities that cause heavy sweating. |
| Handle Devices With Care | Store hearing aids in a secure case, remove them over a soft surface, and avoid extreme heat or cold. |
| Replace Batteries Wisely | Replace disposable batteries before they lose power completely and use dry storage when appropriate. Rechargeable battery performance may change after four to five years. |
| Stay Up-to-Date on New Technology | Watch for newer models that may offer better functionality, comfort, or features as hearing needs change. |
Follow a Regular Cleaning Routine
Use a soft, dry cloth to wipe your hearing aid daily after use. Then, remove built-up wax and debris with a cleaning tool or brush. Just make sure you clean removable parts, such as ear tips or ear molds, as instructed by your audiologist or manufacturer.
Schedule Professional Maintenance
Aside from daily care, it’s essential to see a professional audiologist for regular hearing aid repair. Experts can perform tasks such as changing filters, cleaning tubing, and checking for issues with microphones or speakers.
Manage Moisture Exposure
As moisture and sweat are common culprits in device damage, invest in a hearing aid dehumidifier or drying station. This is a quick and effective way to keep your hearing aids dry overnight. Always remove your devices before activities that cause heavy sweating, such as a strenuous workout.
Handle Devices With Care
When not in use, store your hearing aids in a secure case to protect them from accidental damage. Always remove them over a soft surface (just in case they slip) and avoid exposing them to extreme heat or cold. (Source.)
Replace Batteries Wisely
Battery health is crucial. Rechargeable models may experience battery lifespan changes after 4-5 years, while hearing aids with disposable batteries benefit from proper storage and handling using dry cases.
Stay Up-to-Date on New Technology
Even if your current hearing aids are functioning properly, keep an eye on advancements that may offer improved functionality and comfort. Upgrading to a newer model every few years helps ensure you’re benefiting from the latest technology.
When Should You Replace Your Hearing Aids?
While regular maintenance can prolong the life of your hearing aids, there are clear signals it may be time for an upgrade:
Keep an eye out for problems like:
- Battery life running out quickly
- Increased frequency of repairs
- Noticing the device is no longer assisting with your hearing
If you notice any of these signs, consult your audiologist to explore the best options for replacement.
Final Thoughts on How Long Do Hearing Aids Last
