Details & Features


Oticon Zeal 1 hearing aids overview

The Oticon Zeal 1 introduces something genuinely new in the hearing aid world - the first In-the-Ear hearing aid that doesn't force you to compromise on the features that matter. For years, choosing a discreet hearing aid meant accepting limitations: no rechargeable batteries, basic sound processing, limited connectivity. The Zeal 1 eliminates all these compromises in one rather clever package.

Currently only available in tech level, it isn't just a smaller version of existing technology with features removed to fit the space. It's a complete rethink of what an In-the-Ear hearing aid can be, using the same premium AI sound processing found in Oticon's Intent range whilst maintaining genuine discretion.

If you've been putting off getting help with your hearing because you're concerned about visibility, or if you've been frustrated by in-the-ear hearing aids that couldn't keep up with your lifestyle, the Zeal 1 changes the equation entirely.

 

Who should consider the Oticon Zeal 1?

The Zeal 1 is ideal if you're hesitant about hearing aids due to visibility concerns but don't want to sacrifice modern features. It's also worth considering if you live an active, connected lifestyle and need seamless smartphone integration, or if you've worn Behind-the-Ear aids but prefer something more discreet. If you simply want the most advanced In-the-Ear technology available, the Zeal 1 delivers premium performance in a nearly invisible package.

 

Oticon Zeal 1 feature highlights

  • BrainHearing technology with second-generation AI
  • The Zeal 1 uses Oticon's BrainHearing philosophy with a Deep Neural Network (DNN 2.0) trained on 12 million real-world sound scenes. This is the same advanced processing found in Oticon's Intent range - not a scaled-down version.
  • The MoreSound Intelligence 3.0 and MoreSound Amplifier 3.0 deliver clear sound across the full frequency range for a richer acoustic experience.

 

BrainHearing technology with second-generation AI

The Zeal 1 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. This isn't a stripped-down version with inferior sound processing - it's the full premium technology in a more discreet package. The MoreSound Intelligence 3.0 and MoreSound Amplifier 3.0 work together to deliver clear sound across the full frequency range, giving you a richer representation of your acoustic environment.

 

Innovative encapsulation technology

The reason the Zeal 1 can pack so much technology into such a small space is down to innovative encapsulation methods - similar to what's used in medical devices like pacemakers. 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.

 

Connectivity that works

Bluetooth connectivity in hearing aids has historically been a bit hit-and-miss, but the Zeal 1 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 1 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 1 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. Simply place your hearing aids in the charger overnight and wake up ready for the day.

 

Same-day fitting

Unlike traditional custom In-the-Ear hearing aids that require ear impressions and waiting weeks for manufacturing, the Zeal 1 uses a modular hybrid design. Your audiologist 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.

 

Additional features

  • SuddenSound Stabiliser - Manages unexpected loud sounds without making them uncomfortable whilst preserving important sounds.
  • Wind and Handling Stabiliser - Monitors and reduces wind and handling noise 500 times per second without affecting speech clarity.
  • Multi-purpose retention antenna - Acts as a Bluetooth connector, extraction cord, and retention device that gradually moulds to your ear's shape.
  • Tap control - Answer calls or adjust settings with a simple double-tap. Discreet and intuitive.

 

Compatible Oticon accessories

  • TV Adapter 3.0 - Streams stereo sound directly from your TV. Set your own volume whilst others listen to theirs.
  • ConnectClip - Remote microphone and hands-free calling device with clear voice pickup even in noise.
  • Easy LE Adapter - Enables streaming from USB-C devices without LE Audio support.
  • Remote Control 3.0 - Physical remote for volume and programme changes.
  • Phone Adapter 2.0 - Connects landline phones to ConnectClip for streamed calls.
  • Companion App - Free smartphone app for discreet control and fine-tuning.

However, none of these accessories are essential - Oticon Zeal hearing aids work perfectly well on its own. Your audiologist can advise which, if any, would benefit your lifestyle.

Conclusion

This is premium technology with premium pricing. For someone who's been avoiding hearing aids due to visibility concerns or wants modern performance without advertising it, the Zeal 1 could be transformative.

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.
