Oticon Zeal hearing aids

The Oticon Zeal Hearing Aid Range

The hearing aid many have been waiting for

Oticon's Zeal hearing aid brings us something genuinely new in the hearing aid world - and that's quite a claim to make in an industry where "revolutionary" often means "slightly better than last year's model".

But the Zeal actually delivers on this promise by creating an entirely new category: the NXT In-the-Ear style.

For the first time, you can have a discreet, in-the-ear hearing aid that doesn't force you to compromise on the features that matter - Bluetooth connectivity, rechargeable batteries, and premium AI sound processing all in one rather clever package.

This isn't about choosing between discretion and functionality anymore. The Zeal gives you both, which is exactly what people have been asking for but manufacturers haven't been able to deliver until now.

Oticon Zeal Hearing Aids

Zeal breaks the mould

Traditionally, if you wanted a discreet hearing aid that sat in your ear, you'd have to accept certain limitations. No rechargeable batteries, limited connectivity, basic sound processing and compromises everywhere.

The Zeal is different, as it uses innovative encapsulation technology - similar to what's used in medical devices like pacemakers - to pack full-featured hearing aid technology into a surprisingly compact device that sits comfortably in your ear canal.

The result is a hearing aid that's genuinely difficult to spot when you're wearing it, but doesn't ask you to sacrifice the modern features you'd expect from premium hearing technology.

It's an approach that makes a lot of sense, particularly for people who've been putting off getting help with their hearing because they're concerned about visibility.

Oticon Zeal Quick Feature Highlights

BrainHearing technology with second-generation AI

The Zeal uses Oticon's BrainHearing philosophy, which focuses on supporting how your brain naturally processes sound rather than just making things louder.

The second-generation Deep Neural Network (DNN 2.0) has been trained on 12 million real-world sound scenes, which means it's genuinely good at distinguishing speech from background noise and adapting to different environments automatically.

This is the same advanced processing technology found in Oticon's Intent range, which tells you something about how seriously Oticon has taken the Zeal.

This isn't a stripped-down version with inferior sound processing - it's the full premium technology in a more discreet package.

Connectivity, charging, and fit

 

Connectivity that actually works properly

Bluetooth connectivity in hearing aids has historically been a bit hit-and-miss, but the Zeal uses the latest Bluetooth LE Audio standard, which provides better sound quality and more reliable connections. You can stream phone calls, music, and other audio directly to both ears with genuinely stable connectivity.

The Zeal is also the first hearing aid enabled for Google's Fast Pair, which means Android users can pair their hearing aids effortlessly. Once paired, the connection is automatically recognised across other Android devices logged into the same Google account - a small detail that makes a surprisingly big difference to daily convenience.

The aids are also Auracast-ready, which prepares them for the next generation of public audio sharing technology. Whilst Auracast isn't widely available yet, having your hearing aids ready for it means you won't need to upgrade when venues start using this technology for broadcasting audio.

 

All-day rechargeable power

The Zeal uses a lithium-ion rechargeable battery that provides up to 20 hours of use on a single charge, including streaming. The charging technology is impressively quick - 15 minutes gives you four hours of use, whilst 30 minutes provides eight hours. A full charge takes just two hours.

The portable SmartCharger is particularly clever, with a built-in power bank that provides up to three additional full charges when you're away from mains power. This means you can go on weekend trips without worrying about finding somewhere to plug in every night.

Same-day fitting without the faff

Unlike traditional custom In-the-Ear hearing aids that require ear impressions and waiting weeks for manufacturing, the Zeal uses a modular hybrid design. Our audiologists can fit them on the same day using medical-grade silicone domes or custom tips, getting the right fit without the lengthy process.

For people with unusual ear canal shapes or retention issues, custom micromoulds are still an option, but most people find the standard fitting works perfectly well.

This immediate fitting is genuinely useful - you can walk out of your appointment actually wearing your new hearing aids rather than waiting weeks to try them.

Oticon Zeal Additional Features

Innovative encapsulation technology

The reason the Zeal can pack so much technology into such a small space is down to innovative encapsulation methods. The entire device is enclosed in a single, solid structure that's both robust and moisture-resistant with an IP68 rating.

This approach not only makes the hearing aid more protected and compact, but also eliminates issues with battery corrosion that can plague traditional designs.

It's the sort of clever engineering that you don't really notice until you compare it with older technology and realise how much better it is.

Natural sound quality

The Zeal uses the same processor and speaker unit as Oticon's Intent miniRITE hearing aids, which means you're getting Receiver-in-Canal (RIC) quality sound from an In-the-Ear device.

The MoreSound Intelligence 3.0 and MoreSound Amplifier 3.0 work together to amplify across the full frequency range, delivering clear sound input with a richer representation of your acoustic environment.

SuddenSound Stabiliser

We've all experienced those moments - you're having a quiet conversation when someone drops cutlery or slams a door.

The Zeal's SuddenSound Stabiliser detects these unexpected loud sounds and manages them without making them uncomfortable, whilst still preserving the important sounds you need to hear.

It's a small feature that makes a noticeable difference to daily comfort.

Wind and Handling Stabiliser

The Zeal monitors for wind and handling noise 500 times per second, reducing these irritating sounds without affecting speech clarity.

This matters more than you might think - previous In-the-Ear (ITE) hearing aids could be surprisingly sensitive to wind noise and the sound of touching the aids themselves.

Who should consider the Oticon Zeal?

 

The Zeal is ideal for several groups of people

If you're considering hearing aids for the first time but have been hesitating because you're concerned about how visible they'll be, the Zeal removes that barrier while giving you genuinely premium technology. You won't need to sacrifice features to maintain discretion.

For people who live active, connected lifestyles and need their hearing aids to integrate seamlessly with their smartphones and other devices, Zeal's modern connectivity features make it a natural fit.

The combination of reliable Bluetooth, hands-free calling, and quick charging means you can use these aids the way you use your other technology - without constantly thinking about them.

The Zeal is also worth considering if you've previously worn Behind-the-Ear (BTE) hearing aids but would prefer something more discreet, as long as your hearing loss falls within the Zeal's fitting range (mild to moderate to severe). You're not giving up performance to gain discretion with this model.

Finally, if you simply want the most modern hearing aid technology available in an In-the-Ear format, the Zeal delivers that. The second-generation AI sound processing, premium connectivity, and innovative design represent the current state of the art for this style of hearing aid.

 

Available technology levels

The Zeal is available in one premium technology level, Oticon Zeal 1 hearing aids, which includes all the features discussed above. Oticon has chosen not to offer multiple performance tiers for this model, which actually simplifies the decision-making process considerably.

You're getting the full package of features, and the choice becomes whether this style and approach suit your needs rather than trying to navigate different technology levels.

Available in colours: The Zeal comes in 'Matt Black', though honestly, given how discreet the design is, most people won't notice regardless of the colour.

Suitable for: Mild to moderate to severe hearing loss. For severe hearing loss, custom earmoulds may be needed to provide adequate retention and acoustic seal.

Compatible app: Oticon Companion app for remote adjustments and controls. 

Compatible accessories:  The Oticon Zeal works with several useful accessories that can enhance your hearing experience in specific situations. These are all optional extras, but worth knowing about if you have particular needs.  

None of these are essential - the Zeal works perfectly well on its own for most situations. But if you regularly watch TV, attend lectures, use landline phones, or find yourself in specific challenging listening environments, the right accessory can make a real difference. Your audiologist can advise which, if any, would actually benefit your lifestyle.

FAQs

What is the best hearing aid model for me?

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.

  • Audiologist's level of knowledge: The audiologist you have seen will hopefully have a wide knowledge of all available hearing aids; however, some will only be familiar with a small number of brands and, therefore, may not really be in a position to know which model is the best for you. It is OK to challenge their recommendation and ask them to justify why this particular brand is the one for you.
  • Do research: Read about the hearing aid that was recommended. Does it seem like it will suit your lifestyle? Does it have more or fewer features than you need? 
  • Be aware of sales targets: Many high street retailers have specific tie-ins to a particular manufacturer/brand. The hearing aid they have suggested may still be the correct one for you, but do your research so that you know why they might have recommended it.
Do I need one hearing aid or two?

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.

What are the benefits of rechargeable hearing aids?

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.

Are Behind-the-Ear hearing aids better than In-the-Ear hearing aids?

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.

What are channels, and how many do I need?

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.

What's covered in a manufacturer's warranty?​

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.

How much does the hearing test cost?

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.

Do you offer home visits, and are they included in the price?

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.

Why are your hearing aids cheaper than what I'd pay on the high street?

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.

How long do I have to try the hearing aids before committing to keep them?

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.
