Overview | Average life expectancy | The 5 main things that affect hearing aid lifespan | Conclusion
Last Hearing Aid UK Update: 18
Choosing a hearing aid is a complex process with so many different factors to consider, especially if you are at the start of your hearing loss journey. The style, model, brand, whether it’s rechargeable, your budget, and hearing loss needs are all weighable considerations.
Like your mobile, another consumable investment, are you also thinking about how long these devices will actually last? Just like cars, two people can buy the same style and brand; however, due to them both being used very differently, they will have different mileage, and ultimately lifespans - and here’s why:
Most well-made modern hearing aids will last between three and seven years; however, there are a few factors that will be the ultimate decider. In this article, we focus on what we believe to be the five main ones.
Naturally, over time, your hearing loss may change, which can affect how long your hearing aids last. For example, your current hearing aids might not be supporting your hearing needs as they used to, due to deterioration. In this case, you may need more powerful hearing aids that would suit your new needs better.
In severe cases, a cochlear implant might be required (which would need to be managed by your local NHS ENT department). Technology is also at play, as you might develop tinnitus and need a solution that has the most advanced tinnitus therapy and masking.
Such things as earwax, dust, skin oils, and sweat may not be the nicest topics to talk about, or even to bear in mind, but they are equally as important regarding hearing aid longevity.
It is well known that cleaning your hearing aids every day, as advised and directed by your audiologist, will go some way to help extend the life of your devices. Most audiologists offer a professional cleaning service in their clinics, which may or may not be chargeable.
Your audiologist should also have replaceable parts, like earmould tubes, silicone domes, and wax guards, available as and when you need to maintain them. Other, more technical parts, such as battery doors, external speakers, and microphone covers, can be repaired and replaced.
Your audiologist will be able to send your aids off to the manufacturer of your hearing aids, but check if you are covered for such repairs under the manufacturer’s warranty.
These little maintenance and cleaning processes are all good habits to have in place for helping to make your hearing aids last as long as possible.
Hearing aids get put through their paces continuously as the weather moves through seasons each year. They have to combat damp, dust, cold, warm, and windy conditions, and if not protected and cared for properly, they can have performance issues.
Ask your audiologist about the protective measures you can put in place if you are concerned about your common environments. They might recommend protective sleeves, for instance, which can extend your hearing aid lifespan.
Hearing aids are tough and reliable pieces of technology, but they are computers at the end of the day, and show vulnerability. This is due to the nature of the materials used, such as plastic, metal, silicone, and polymers, which are typically used.
The good news is that many recent modern hearing aids do have an IP68 coating, which means they show some level of resistance to water, dust, and moisture. This doesn’t mean that you can disregard general maintenance and care, but there is some protection there.
When looking at rechargeable batteries, hearing aids with lithium batteries usually last around four to five years. We could mirror this average when we think about mobile phones. The longer you have the device, the shorter the battery life gets.
However, if you think your rechargeable hearing aids are losing battery faster than usual, speak to your audiologist, and they will advise further. This could be replacing the batteries, looking at upgrades, or analysing storage solutions (as colder temperatures are known to drain batteries more quickly).
Alternatively, it might be as simple as investing in a dehumidifier to keep them stored safely and keep them dry. Let’s take a look at hearing aid styles and how they might affect the life of a hearing aid. The industry has stated before that Behind-Ear styles seem to have a longer lifespan than In-Ear designs.
This is simply down to the positioning of the device itself, as the electrical components of In-Ear models sit within your ear canal, and therefore a more damp environment.
Recent advancements in technology now mean that modern hearing aids have nano-coatings on both internal and external parts, in the hope that this increases durability in the future.
As hearing aid manufacturers develop their technology, naturally, older styles eventually become obsolete, making replacement parts harder to access, when repairs are needed, if not impossible. This can be the same for software, so reprogramming older aids might not be possible.
At the end of the day, how long your hearing aids last is largely in your hands. While most devices are built to go the distance, typically anywhere between three and seven years, the care and attention you give them day to day makes a real difference.
It's also worth remembering that your hearing needs may naturally evolve over time, and that's okay. Technology moves fast, and what worked perfectly for you a few years ago might not be giving you the same level of support today. If something doesn't feel right, don't wait; your audiologist is always the best first port of call.
Hearing aids are a long-term investment, and getting the right ones from the start makes all the difference.

How long do hearing aids last?
Parts of a hearing aid
What hearing aid features do I actually need? Do not spend hundreds of pounds without getting a second opinion from us.
Not only are the prices great, but the service is fantastic! Many thanks to your team.In general, any audiologist will always recommend to you the hearing aid model that best suits your needs. Here is a useful checklist to make sure that is the case.
If you have significant hearing loss in both ears, you should be wearing two hearing aids. Here are the audiological reasons why:
Localisation: The brain decodes information from both ears and compares and contrasts them. By analysing the minuscule time delays as well as the difference in the loudness of each sound reaching the ears, the person is able to accurately locate a sound source.
Simply put, if you have better hearing on one side than the other, you can't accurately tell what direction sounds are coming from.
Less amplification is required: A phenomenon known as “binaural summation” means that the hearing aids can be set at a lower and more natural volume setting than if you wore only one hearing aid.
Head shadow effect: High frequencies, the part of your hearing that gives clarity and meaning to speech sounds, cannot bend around your head. Only low frequencies can. Therefore, if someone is talking on your unaided side, you are likely to hear that they are speaking, but be unable to tell what they have said.
Noise reduction: The brain has its own built-in noise reduction, which is only really effective when it is receiving information from both ears. If only one ear is aided, even with the best hearing aid in the world, it will be difficult for you to hear in background noise as your brain is trying to retain all of the sounds (including background noise) rather than filtering them out.
Sound quality: We are designed to hear in stereo. Only hearing from one side sounds a lot less natural to us.

For most people, the main benefit of a rechargeable hearing aid is simple convenience. We are used to plugging in our phones and other devices overnight for them to charge up. Here are some other pros and cons:
For anybody with poor dexterity or issues with their fingers, having a rechargeable aid makes a huge difference, as normal hearing aid batteries are quite small and some people find them fiddly to change.
One downside is that if you forget to charge your hearing aid, then it is a problem that can't be instantly fixed. For most, a 30-minute charge will get you at least two or three hours of hearing, but if you are the type of person who is likely to forget to plug them in regularly, then you're probably better off with standard batteries.
Rechargeable aids are also a little bit bigger and are only available in Behind-the-Ear models.
Finally, just like with a mobile phone, the amount of charge you get on day one is not going to be the same as you get a few years down the line. Be sure to ask what the policy is with the manufacturer's warranty when it comes to replacing the battery.
For most people, the answer is yes. But it's never that simple.
The majority of hearing problems affect the high frequencies a lot more than the low ones. Therefore, open fitting hearing aids sound a lot more natural and ones that block your ears up can make your own voice sound like you are talking with your head in a bucket. Therefore, in-ear aids tend to be less natural.
However, the true answer is we can't tell until we have had a look in your ears to assess the size of your ear canal, and until we have tested your hearing to see which frequencies are being affected.
People with wider ear canals tend to have more flexibility, also there are open fitting modular CIC hearing aids now that do not block your ears.
There is also the age-old rule to consider, that a hearing aid will not help you if it's sat in the drawer gathering dust. If the only hearing aid you would be happy wearing is one that people can't see, then that's what you should get.
Most people can adapt to any type of hearing aid, as long as they know what to expect. Have an honest conversation with your audiologist as to what your needs are.
Generally speaking, six or more. Unless it's none at all. The number of channels a hearing aid has is often a simplistic way an audiologist will use to explain why one hearing aid is better than another, but channels are complex, and it is really not that straightforward. Here are some reasons why:
Hearing aids amplify sounds of different frequencies by different amounts. Most people have lost more high frequencies than low, and therefore need more amplification in the high frequencies. The range of sounds you hear is split into frequency bands or channels, and the hearing aids are set to provide the right amount of hearing at each frequency level.
Less than six channels, and this cannot be done with much accuracy, so six is the magic number. However, a six-channel aid is typically very basic with few other features and is suitable only for hearing a single speaker in a quiet room. The number of channels is not what you should be looking at; it's more the rest of the technology that comes with them.
As a final note, different manufacturers have different approaches. One method is not necessarily better than any other. For example, some manufacturers have as many as 64 channels in their top aids. Most tend to have between 17 and 20. One manufacturer has no channels at all.
Manufacturer's warranties typically last between 2-5 years, depending on the brand and model, and cover defects in materials and workmanship. This includes repairs for component failures, electronic malfunctions, and manufacturing defects, but excludes damage from misuse, accidents, or normal wear. Most manufacturers also include loss and damage insurance for the first year.
We handle all warranty claims on your behalf, liaising with manufacturers and ensuring you get replacement devices quickly when needed. This comprehensive warranty coverage, combined with our lifetime aftercare, gives you complete peace of mind.
Our hearing tests are completely free, whether at our clinics or in your home. Unlike other providers who charge £30-£100 for home visits, we believe hearing healthcare should be accessible without financial barriers. Our comprehensive assessments include examination by a registered audiologist, audiogram results, and personalised recommendations.
All testing, future adjustments, and ongoing support are included at no extra cost. While NHS tests are also free, typical 6-week waiting periods often lead people to seek immediate private testing. We provide prompt, professional assessments that fit your schedule and budget.
Yes, we offer completely free home visits throughout the UK, and this service is included in our prices with no additional charges. Home visits are particularly valuable for people with mobility issues, busy schedules, or those who simply prefer the comfort and convenience of their own environment.
Our audiologists can conduct full hearing tests, fit hearing aids, and provide ongoing support in your home. This service sets us apart from many providers who either don't offer home visits or charge extra for them.
We can offer prices up to 40% lower than high street retailers because of our business model. As a network of 200+ independent audiologists, we don't have the massive overheads of large retail chains - no expensive high street premises, no sales targets pushing audiologists to sell the most expensive options, and no costly marketing campaigns.
However, we maintain the same buying power as the big chains because we purchase on behalf of our entire nationwide network. This means you get access to the same premium hearing aids with professional service, but at genuinely competitive prices.
We offer a comprehensive 60-day money-back guarantee, which gives you twice the industry standard time to properly assess whether your hearing aids are right for you. This extended period recognises that adjusting to hearing aids takes time, and your brain needs several weeks to adapt to the amplified sounds.
Unlike many providers who offer just 30 days, we believe 60 days gives you the confidence to test your hearing aids in all the situations that matter to you - from quiet conversations at home to busy restaurants and outdoor activities.
