Quick Answer
Hearing aids typically last between 3 to 7 years, depending on the model, usage, environment, and how well they are maintained. On average, most people find that their devices serve them effectively for around five years before needing replacement. Behind-the-ear (BTE) models often last longer than in-ear types due to reduced exposure to earwax and moisture. However, battery degradation, evolving hearing needs, and advancing technology often drive replacements even before physical breakdown. Proper care, regular maintenance, and professional servicing can significantly extend the lifespan of your hearing aids.

How Long Do Hearing Aids Last? A Comprehensive Guide
Understanding Hearing Aid Lifespan
Hearing aids are built to be durable but, like all technology, they have a finite usable life. Most users can expect their hearing aids to function optimally for three to seven years, with proper care and handling. However, multiple factors—ranging from environmental exposure to battery degradation—can influence exactly how long your devices will last.
While a hearing aid may still technically "work" after seven years, its performance may no longer match your hearing needs, or it may lack the latest features such as AI-powered noise filtering or Bluetooth streaming. That's why hearing aid replacement is often based on more than just wear and tear—it's also about staying current with your hearing health.
Lifespan by Hearing Aid Style
Behind-the-Ear (BTE) and Receiver-in-Canal (RIC)
These are the most durable types, lasting on average 5 to 7 years. Because the electronic components are housed outside the ear, they are less exposed to moisture, wax, and body heat. Their design allows for easier servicing and better airflow, reducing the risk of damage.
In-the-Ear (ITE), In-the-Canal (ITC), and Completely-in-Canal (CIC)
Smaller and more discreet, these styles sit deeper inside the ear and are more vulnerable to moisture, earwax, and corrosion. Their average lifespan is 3 to 5 years, often requiring more frequent professional cleanings.
Invisible-in-Canal (IIC) and Extended Wear
These ultra-compact models often need replacement within 1 to 3 years due to limited space for durable components and battery systems. Extended wear versions are designed to be replaced every few months as part of a subscription service.
7 Key Factors That Affect Hearing Aid Longevity
1. Build Quality and Brand
Premium brands like Phonak, Oticon, ReSound, and Starkey use higher-grade materials and components, which typically last longer. Devices from established brands may also be more serviceable and easier to repair, extending their usability.
2. Battery Type
Rechargeable hearing aids are becoming more popular, but lithium-ion batteries degrade over time, usually needing replacement after 3 to 5 years. Traditional battery-powered aids may outlast rechargeables if you’re diligent with maintenance.
3. User Habits and Handling
Rough handling, dropping, and improper storage shorten lifespan. Devices worn during exercise or in humid conditions degrade faster. Gentle daily handling, protective storage, and cleaning can make a significant difference.
4. Environmental Exposure
Dust, heat, humidity, sweat, and earwax all contribute to component breakdown. People in coastal or tropical areas may need to replace their devices sooner unless they use drying cases or hearing aid dehumidifiers nightly.
5. Maintenance and Cleaning
Hearing aids should be cleaned daily with a soft cloth. Wax guards and filters need regular replacement. Professional cleanings every 6 months help prevent internal buildup and corrosion, extending the life of internal components.
6. Changes in Hearing Loss
If your hearing changes significantly, your current device may no longer provide sufficient amplification—even if it still functions. Upgrading early ensures optimal hearing performance and better quality of life.
7. Technological Obsolescence
In just a few years, hearing aid technology can advance dramatically. Newer models offer machine learning, Bluetooth streaming, rechargeable batteries, tinnitus masking, and real-time noise cancellation. Users often replace devices early to access new tech.

Signs It’s Time to Replace Your Hearing Aids
-
Frequent or repeated repairs
-
Reduced sound clarity, even after reprogramming
-
Shorter battery life
-
Whistling or feedback noises
-
Intermittent performance

Your audiologist recommends a new device based on test results
If you’re experiencing any of these issues, it's wise to consult a hearing care professional for an assessment.
Tips to Extend the Life of Your Hearing Aids
Daily Cleaning
Wipe down the exterior of your hearing aids with a soft cloth. Remove any visible wax or debris from openings. Avoid using water or alcohol-based cleaners.
Moisture Management
Store your devices in a hearing aid dehumidifier overnight. Never wear hearing aids in the shower or while swimming. Remove them during intense sweating or in very humid environments.
Battery Maintenance
If using rechargeable devices, avoid draining them completely and always recharge using the recommended charger. If using disposables, store batteries in a cool, dry place and replace them regularly.
Scheduled Servicing
Book professional cleanings and inspections every 6 months. This ensures wax guards, tubing, domes, and filters are in good condition and helps prevent minor issues from becoming major repairs.
Proper Storage
When not in use, place your hearing aids in their case, preferably with a drying capsule. Keep them out of reach of pets and children.
Avoid Hair and Body Products
Remove hearing aids before applying hairspray, cologne, or sunscreen, as these products can damage microphone ports and casing seals.
When to Plan for Replacement
Although a hearing aid may last up to seven years, most audiologists recommend planning to replace your devices every 4 to 6 years, depending on your circumstances. Budgeting ahead ensures you’re not caught off-guard by a sudden failure or performance decline.
Also, schedule annual hearing evaluations. If your hearing loss progresses, an older device might not keep up with your new thresholds—even if it’s still operational. In this case, an upgrade could restore clarity and improve your day-to-day interactions.
Future-Proofing Your Investment
Many modern hearing aids are software-upgradable, meaning features and performance enhancements can be delivered via firmware updates. Choosing brands and models with ongoing support and upgrade paths can help extend the value of your purchase.
Also consider extended warranties or service plans, which can cover repairs, replacements, and accessories for a longer period—protecting your investment and simplifying maintenance costs.
Conclusion
The longevity of your hearing aids isn’t just determined by their hardware—it’s shaped by how you use, clean, and care for them. On average, hearing aids last between 3 to 7 years, but attentive maintenance and timely servicing can stretch their lifespan, while evolving hearing needs or advancing technology may prompt an earlier upgrade.
To get the best value from your devices:
Handle with care
Store properly
Clean them daily
Service them regularly
Stay in touch with your hearing care provider
Ultimately, your hearing health is an evolving journey. Keeping your hearing aids updated ensures you’re always tuned in to the sounds that matter most.
