Details & Features


Phonak Audeo Infinio i70 hearing aids overview

The Phonak Audeo Infinio i70 hearing aids, also known as Phonak Audeo i70-R, are engineered to deliver great sound quality and comfort from the very first use.  Featuring advanced technology, these hearing aids aim to offer seamless and confident interaction with the world.

Think about that moment when you're confidently participating in your book club discussion, catching every nuanced opinion about the latest novel.

Or picture yourself at your daughter's graduation ceremony, hearing every word of her valedictorian speech clearly, even from the back rows. The i70 is designed for people who want to be fully present in these meaningful moments without breaking the bank.

Positioned as the upper-mid level option in the Infinio range, the Phonak Infinio i70 hearing aids are designed for those who want strong performance in varied listening situations without stepping into the premium price tier.

Significant upgrades include enhanced durability, advanced processing chips, and more efficient Bluetooth connectivity.  All Infinio models incorporate the ERA chip, focusing on superior sound quality, connectivity, and personalisation. Key features include:

  • Sound quality: The new APD 3.0 fitting model ensures improved sound from the first use, with Harman Curves for optimal frequency response and SmartSpeech technology, which enhances speech understanding by 16% and reduces listening effort by 45%.
  • Connectivity: Universal Bluetooth connectivity allows effortless switching between streaming and acoustic inputs, with six times the transmission power for more reliable connections.
  • Reliability and battery life: Infinio models are IP68-rated for water and debris resistance and offer 16 hours of battery life.

The Phonak Infinio i70 hearing aids provide an excellent balance between performance and value, supporting features like directional microphones, feedback cancellation, and environmental sound classification for everyday confidence in hearing.

 

Infinio vs Infinio Sphere

While both models include advanced features, the Infinio Sphere model uses dual-chip AI technology (DEEPSONIC and ERA) for dynamic adaptation in complex sound environments. The Infinio model, featuring a single ERA chip, delivers dependable performance for wearers who do not require advanced AI processing.

Phonak reports that the Sphere Infinio offers a 10 dB signal-to-noise ratio (SNR) improvement without additional accessories and reduces listening effort by 45% in quiet environments for those with moderate to severe hearing loss.

The Speech Enhancer function decreases fatigue by 21%, and speech understanding is said to improve by 61% when using the Roger ON mic.  Durability has been increased with enhanced waterproofing, making the devices more resilient, though they are not intended for lap swimming.

The Phonak Infinio i70 hearing aids, while not AI-driven, still provide significant support in daily listening situations, especially in group conversations, outdoor settings, or soft-spoken voices.

The i70 is like choosing the well-equipped trim level of a reliable car – you get all the features that genuinely improve your daily experience, without paying for luxury extras you might rarely use. It's smart technology that focuses on what matters most: clear communication and confident hearing in real-world situations.

 

Hearing aid product highlights

  • The ultra-responsive ERA chip in all Infinio models boosts digital signal processing for superior sound quality.
  • Improved speech understanding and reduced listening effort help minimise fatigue throughout the day.
  • Compatible with CROS for those with unilateral hearing loss.
  • Speech Enhancer and WindBlock features in the Phonak Infinio i70 hearing aids allow users to enjoy clearer conversations outdoors or in breezy environments.
  • Environmental Balancer technology helps adjust audio settings automatically, reducing the need for manual adjustments in changing sound environments.

A recent customer shared how the i70 transformed their weekly coffee dates with friends – they went from feeling anxious about group conversations to looking forward to the lively discussions. Another told us how they finally felt comfortable attending their grandson's school plays, knowing they wouldn't miss any of the dialogue or musical numbers.

 

Practical daily life examples

  • Morning school pickup conversations where you catch every detail about homework and weekend plans
  • Afternoon shopping trips where checkout interactions and friendly chatter with neighbours flow naturally
  • Evening family dinners where you're part of every story, joke, and planning discussion
  • Weekend social gatherings where moderate background noise doesn't stop you from enjoying conversations
  • Phone calls with distant relatives, where every precious update comes through clearly

 

Emotional benefits

  • Confidence in everyday social situations without the premium price
  • Peace of mind knowing you have advanced technology that adapts to your lifestyle
  • Pride in making a smart, value-conscious choice that still delivers exceptional results
  • Relief from the stress of choosing between basic and premium – the i70 is your perfect middle ground
  • Joy in rediscovering effortless conversations with family and friends

 

Universal connectivity

Phonak Audeo Infinio i90 hearing aids offer broader Bluetooth connectivity than any other hearing solution currently available. The new ERA chip supports hands-free calls and streaming at twice the distance compared to the previous Lumity model, delivering stronger and more reliable Bluetooth performance.

  • Connect to up to 8 Bluetooth devices, with 2 active simultaneously.
  • Automatically switch between acoustic and streaming modes to ensure you never miss a word.
  • RogerDirect technology enhances hearing in noisy environments and over long distances.

While the Phonak Infinio i70 hearing aids don't offer all premium-level connectivity options found in the i90, they still provide robust and reliable Bluetooth streaming for day-to-day use, ideal for phone calls, music, and TV audio.

Think of the ERA chip as having a smart assistant who's always working to make your conversations clearer, but never gets in the way or overcomplicates things. It's advanced technology that feels natural and effortless – exactly what you want from a hearing aid.

 

Hearing aid accessories, colours, and app

The Phonak Audeo Infinio-R i70 hearing aids are compatible with accessories such as the TV Connector, Phonak PartnerMic, Phonak RemoteControl, Roger microphones, and the myPhonak app. Charging options include the Phonak Charger RIC I and ChargerGo RIC I.

What about size and battery life? These hearing aids are comparable in size to the Lumity model, with the Infinio i70 offering up to 16 hours of battery life on a full charge and an additional 3 hours for Bluetooth streaming.

These hearing aids are available in various colours, including Sand Beige, Champagne, Silver Grey, Chestnut, and Graphite Grey. The Phonak Infinio i70 hearing aids blend discreet design with reliable performance, offering a comfortable, Behind-the-Ear style suitable for long-term daily wear.

 

Comparing the i70 with i90

These hearing aids are suitable for mild to severe hearing loss and can also be fitted with a dome, canal mould, or other types of earmoulds.  The Phonak i70 offers most of the Infinio features, such as WindBlock and StereoZoom. 

Therefore, these hearing aids should benefit wearers who have an active lifestyle and tend to spend time in smallish groups with moderate background noise.

Compared to the i90 model, the Phonak Infinio i70 hearing aids may lack a few of the more advanced automation features, but they remain a smart and capable choice for those wanting strong speech clarity, reliability, and comfort without the top-tier price tag.

Many customers tell us the i70 is their "sweet spot" choice – sophisticated enough to handle their active lifestyles, reliable enough for daily confidence, and sensibly priced enough to feel good about the investment. It's premium performance with practical wisdom.

 

Why buy?

Don’t let hearing challenges hold you back.  Discover the innovative Phonak Audeo Infinio-R i70 hearing aids, designed to redefine your listening experience. With advanced technology like the ultra-responsive ERA chip, enjoy superior sound quality, enhanced speech understanding, and effortless Bluetooth connectivity - all while staying comfortable throughout your day.

Explore the incredible features, from universal Bluetooth connectivity to impressive battery life, and find the perfect fit for your lifestyle.  Learn more and take the first step toward clearer hearing!

The Phonak Infinio i70 hearing aids are especially well-suited for those who want reliable performance in everyday situations, from quiet conversations to moderate background noise, without overpaying for features they may not need.

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.
