ReSound hearing aids typically last about 5 years, according to ReSound’s own guidance. That’s in line with the broader hearing aid industry, where most devices fall in the 4 to 7 year range depending on how well they’re maintained, how often they’re worn, and the environment they’re exposed to daily.
What Determines the 5-Year Lifespan
Hearing aids live in one of the harshest environments imaginable for electronics: your ear canal. They’re exposed to moisture, body heat, earwax, sweat, and skin oils for 12 to 16 hours a day. Over time, these elements corrode internal components, degrade microphones, and wear down receivers. The 5-year figure reflects how long the average device holds up under these conditions before repairs become frequent or sound quality noticeably declines.
Some people get 6 or 7 years from their ReSound aids. Others start having issues around year 3 or 4, especially in humid climates or if maintenance has been inconsistent. The physical hardware is only part of the equation. Software support also matters. As ReSound releases new models and updates its app, older devices eventually lose compatibility with newer phones and streaming features, which can make them feel outdated even if they still technically work.
Daily Battery Life vs. Device Lifespan
It’s worth separating two different “battery life” questions. The first is how long your hearing aids run on a single charge or set of batteries each day. The second is how long the rechargeable battery inside the device holds up over months and years.
For daily use, ReSound’s current rechargeable models provide up to 24 hours of typical use on a full charge, or about 20 hours if you’re streaming audio roughly half the time. The maximum is 30 hours under light use. If you use disposable batteries instead, a size 312 battery lasts 3 to 10 days, while a size 13 lasts 6 to 14 days, depending on your usage and streaming habits.
The rechargeable lithium-ion battery inside the hearing aid itself degrades over time, just like a phone battery. After 2 to 3 years of nightly charging, you may notice the daily runtime starts to shorten. ReSound’s rechargeable batteries are sealed inside the device, so replacing them typically requires sending the aids back to the manufacturer or visiting your audiologist.
Repair Costs After Warranty
ReSound hearing aids come with a manufacturer warranty, usually 2 to 3 years depending on the model and where you purchase them. Once that warranty expires, repairs come out of pocket. Based on user reports, out-of-warranty factory repairs for ReSound devices run around $300 to $325 per hearing aid. That’s for issues requiring the device to be sent back to ReSound, such as a failed receiver or corroded circuit board.
At some point, the math stops making sense. If you’re facing a $600+ repair bill for both aids and they’re already 4 or 5 years old, upgrading to a new pair often provides better value, especially given the improvements in sound processing and Bluetooth connectivity that come with newer models.
How to Get the Most Years From Your Pair
Maintenance is the single biggest factor you can control. Current ReSound models carry an IP68 rating, the highest available, meaning they resist dust and can handle brief submersion in water. But water resistance degrades over time as seals wear, so keeping them dry remains important. Remove them before showering, swimming, or heavy exercise, and store them in a dry, cool place overnight. A hearing aid dehumidifier or drying kit is a worthwhile investment, especially if you live somewhere humid or tend to sweat.
Daily cleaning makes a real difference in longevity. Brush the microphone ports every day with the soft-bristled brush that comes with your aids. This prevents debris from working its way deeper into the device where it can muffle sound or damage components. For receiver-in-canal models (the most common ReSound style), check and replace the wax guard weekly, or whenever sound starts to feel weak or muffled. These tiny filters block earwax from reaching the receiver, and a clogged guard is the most common reason people think their hearing aid is dying when it actually just needs a $2 replacement filter.
Avoid using sharp objects, compressed air, or household cleaners on any part of the device. When handling wax guards, use the removal and insertion tool that comes in the replacement pack. Your audiologist can also professionally clean and vacuum the aids during routine visits, reaching debris that home cleaning can miss.
When Replacement Makes More Sense Than Repair
Beyond physical wear, your hearing itself changes over time. A device fitted 5 years ago may no longer match your current hearing profile, even after reprogramming. If your audiologist has adjusted your aids to their maximum output and you’re still struggling to hear clearly, the device may have simply reached the limit of what it can amplify for your level of loss.
Technology gaps also accumulate quickly. A ReSound model from 2019 lacks the noise reduction, directional microphone processing, and app features found in 2024 devices. If you rely on Bluetooth streaming for phone calls or media, older models may not pair reliably with current smartphones. These functional limitations often push people toward replacement before the hardware actually fails, putting the practical lifespan closer to 4 or 5 years for people who want current features and seamless connectivity.
