Phonak Audéo Infinio Sphere Hearing Aids

Following a conversation in a busy room, a family gathering or a crowded restaurant is one of the most common frustrations people describe when their hearing changes. The Phonak Audéo Infinio Sphere is Phonak’s flagship hearing aid, built specifically to help with exactly this challenge. At DigiClear Hearing, our audiologists can talk you through whether it is the right fit for your hearing needs, alongside the other Phonak devices and manufacturers we work with.

What is the Phonak Audéo Infinio Sphere?

The Audéo Infinio Sphere sits at the top of Phonak’s Infinio range, alongside the Infinio Ultra R and Virto R Infinio. It is a rechargeable, receiver-in-canal hearing aid, worn discreetly behind the ear with a thin wire running down to a receiver that sits in the ear canal. Phonak positions the device as suitable for mild to profound hearing loss, and it introduces a level of on-device processing that Phonak has not previously offered elsewhere in its range.

Phonak is part of the Sonova group, which also owns the Unitron brand, and the Infinio Sphere follows on from Phonak’s earlier Lumity and Paradise hearing aid platforms. Phonak states that the Infinio Sphere is built around a dedicated AI chip, developed specifically to separate speech from background noise in every direction at once, rather than simply reducing overall noise levels in the way earlier platforms did.

The device is available in a range of finishes, including Sand Beige, Sandalwood, Chestnut, Champagne, Silver Grey, Graphite Grey and Velvet Black, so it can be matched to hair colour or personal preference. Your audiologist can show you the full colour range and let you handle the device itself at your consultation, rather than relying on photographs alone.

A dedicated AI chip for speech in noise

The headline feature of the Infinio Sphere is DEEPSONIC, which Phonak describes as the world’s first dedicated AI chip for all-around speech-from-noise separation. It powers what Phonak calls Spheric Speech Clarity 2.0, a processing system designed to extract, enhance and integrate speech from multiple voices in real time, regardless of which direction they are coming from.

DEEPSONIC works alongside AutoSenseOS 7.0, Phonak’s automatic sound classification system, which continually assesses the wearer’s surroundings and adjusts settings without any manual input needed. In a quiet one-to-one conversation, a busy office, or a noisy family meal, the device is designed to recognise the change in environment and reprocess sound accordingly.

In practical terms, this means a wearer is not limited to focusing on whoever is directly in front of them. Phonak’s own research, referenced on its website, reports that wearers were up to three times more likely to understand speech from any direction when using Spheric Speech Clarity 2.0, and that listening effort was reduced by up to 35 per cent compared with the previous StereoZoom 2.0 system. These are Phonak’s published findings from its own field studies rather than independently verified figures, and we are happy to share the source with you if you would like to look into the detail yourself.

How this compares with earlier Phonak technology

Previous top-tier Phonak devices used a feature called StereoZoom to narrow focus onto whoever the wearer was facing. This worked well for a single conversation partner, but could make it harder to follow a conversation that moved naturally around a group, such as at a dinner table or in a meeting. Phonak states that Spheric Speech Clarity 2.0 was designed to address this directly, processing sound from all directions at once rather than narrowing focus to one speaker.

According to Phonak’s published field studies, this approach reduced listening effort by up to 35 per cent compared with StereoZoom 2.0, in testing with adults with moderate to severe hearing loss. As with all manufacturer figures, we would encourage you to treat these as Phonak’s own findings rather than independently verified results, and to ask your audiologist for the underlying study if you would like to read it in full before making a decision.

Built for everyday life

  • Up to 56 hours of battery life on a single charge, based on Phonak’s typical usage assumptions
  • Compatible with Phonak’s EasyGuard dome, designed to help protect the receiver from earwax
  • Universal Bluetooth connectivity for calls and streaming, across a wide range of devices
  • Works with Phonak’s Roger wireless microphones, useful in meetings, classrooms or noisy social settings
  • Controlled through the myPhonak app, for adjusting volume and programmes without reaching for the device itself

These features are designed to work together, so that clearer hearing in noise does not come at the cost of convenience or reliability throughout the day. A device that needs frequent recharging, or that struggles to connect to a phone reliably, can undo a lot of the benefit of better speech processing, so Phonak has built the Infinio Sphere with everyday practicality in mind as well as raw performance.

Roger wireless microphones and connectivity

For situations where background noise is particularly challenging, the Infinio Sphere can be paired with Phonak’s Roger wireless microphones. These transmit speech directly to the hearing aids over distances of up to around 25 metres, which can make a noticeable difference in places such as large meeting rooms, lecture theatres or noisy family gatherings.

  • Roger On, a versatile microphone for changing listening situations, which recognises the direction sound is coming from
  • Roger Select, which automatically identifies whoever is speaking when placed on a table, with manual selection available when several conversations are happening at once
  • Roger Table Mic, aimed at meetings, which can be linked with other Roger microphones so everyone in a group can be heard clearly
  • Roger Clip-On Mic, designed for one-to-one conversations, which clips onto clothing or hangs around a conversation partner’s neck

None of these accessories are essential for everyday use, and many wearers are perfectly happy with the Infinio Sphere alone. They are worth discussing with your audiologist if you regularly find yourself in large meetings, lecture settings, or other situations where a single hearing aid microphone has its limits.

The devices also include an Ultra Focus feature which is activated with the push of a button. This technology provides guaranteed hearing in a one-to-one conversation, even in the busiest environments. You’ll no longer need to worry about a crowded restaurant or coffee shop disrupting your dialogue!

Hearing and wider wellbeing

For many people, hearing well is about more than following speech in a noisy room. It also affects staying connected with family, taking part fully in conversations at work, and feeling comfortable in social situations rather than avoiding them. Choosing the right hearing aid, and having it properly fitted and adjusted by a qualified audiologist, is often the biggest single factor in how much difference it makes to daily life, more so than any individual feature on its own.

Is the Infinio Sphere right for you?

The Infinio Sphere is one option among several in the Phonak range, and it will not be the right choice for everyone. Because it sits at the premium end of the range, it tends to suit people who spend a lot of time in noisy or unpredictable listening environments, such as busy workplaces, family gatherings, or social occasions with several people talking at once. For someone whose daily listening environments are generally quieter, a different Phonak device, or a hearing aid from one of the other manufacturers we work with, may represent better value without any real difference in day-to-day experience.

The only way to know whether it suits your hearing loss, lifestyle and budget is through a proper hearing assessment. Our audiologists will talk you through how the Infinio Sphere compares with other Phonak devices, such as the Infinio Ultra R, and with equivalent devices from other manufacturers, so that you can make an informed choice rather than a guess based on marketing alone.

Support with fitting and aftercare at DigiClear

A hearing aid only performs as well as its fitting. When you choose the Phonak Audéo Infinio Sphere through DigiClear, your audiologist will carry out a full hearing assessment, fit the device to your individual hearing profile, and fine-tune the settings over one or more follow-up appointments. This typically includes checking real-world performance in the situations that matter most to you, not just in a quiet consultation room.

Ongoing support does not stop once the device is fitted. Routine care includes cleaning and maintenance advice, help setting up the myPhonak app and any Roger accessories, and adjustments as your hearing or listening needs change over time.
