Phonak Audéo Infinio Ultra – Premium Rechargeable Hearing Aid

Phonak Audéo Infinio Ultra: The Hearing Aid That Thinks As Fast As Real Life Moves

Phonak has never been content to build hearing aids that simply make things louder. Since the very beginning, the company's driving question has been more demanding than that: what does it actually take for a person with hearing loss to feel fully present in a conversation, in a room, in their own life? Not half-present. Not carefully managing where they sit and who they face and how loud the room is. Actually present.

The Phonak Audéo Infinio Ultra is the most complete answer Phonak has given to that question yet. It is a receiver-in-canal hearing aid built on a platform refined through over a million real-world fittings, updated with firmware that makes its already powerful AI engine faster, smarter, and significantly more efficient, and delivered in a device that handles everything from a quiet morning kitchen to a crowded restaurant without asking the wearer to intervene, adjust, or adapt.

Most people will never have to think about what is happening inside it. That is exactly the point.

What Is the Audéo Infinio Ultra, and Why Does It Matter?

When Phonak launched the original Audéo Infinio in 2024, the hearing aid industry took notice. The platform introduced a processing approach built around real-world listening intelligence, outperforming competitors in independent speech-in-noise testing and bringing AI-powered sound management to a level that wearers could actually hear and feel rather than just read about in a specification sheet.

In October 2025, Phonak released the Ultra update, a firmware upgrade informed by data from over one million fittings collected across a full year of real-world use. The result is a hearing aid that uses the same core hardware but runs significantly better in the situations that matter most: harder environments, longer days, more complex listening scenes.

The Infinio Ultra is the foundation of the Phonak Infinio platform. For people who want exceptional AI-powered hearing performance from a reliable, well-established receiver-in-canal design, it is the starting point for everything the platform can do.

AutoSense OS 7.0: The Intelligence That Never Sleeps

The most transformative update inside the Infinio Ultra is AutoSense OS 7.0, Phonak's automatic scene-classification engine, now trained on eighteen times more real-world scenarios than its predecessor.

What that means in practice is a system that is 24 percent more precise at identifying where you are and what the acoustic moment requires. Walking from a calm home into the noise of a car. Stepping out of that car into a busy restaurant. Moving from a loud event into a quieter hallway. AutoSense OS 7.0 reads each transition and adjusts processing in real time, without the wearer touching an app, pressing a button, or doing anything at all except living their day.

The system now recognizes specific music genres, including hip hop, classical, electronic, and jazz, and applies tailored processing for each. It distinguishes speech in a moving car from speech in a noisy café from speech on the telephone. And it does all of this continuously, automatically, and in the background.

For people who have spent years manually switching programs or reaching for their phone every time their environment changes, AutoSense OS 7.0 delivers something that sounds simple but changes everything: a hearing aid that figures it out so they do not have to.

Battery Life That Keeps Pace With a Real Day

Battery anxiety is one of the most common frustrations wearers of advanced hearing aids describe. The more sophisticated the processing, the faster the drain. The Infinio Ultra's 7.0 firmware addressed this directly, delivering a 30 percent improvement in battery efficiency over the original platform.

The Audéo Infinio Ultra R runs on a built-in rechargeable lithium-ion cell. Placed in the charger overnight, it is fully ready by morning. The charger itself stores additional charge for use away from an outlet. A short charge delivers meaningful reserve for a day that runs longer than expected.

The practical effect is that wearers carry less worry through the day. The hearing aid handles more demanding processing more efficiently, so the trade-off between capability and endurance that used to define advanced hearing technology is no longer a calculation the wearer has to make.

EasyGuard: Maintenance Designed to Disappear

The Infinio Ultra introduces EasyGuard, a new receiver protection system built around an acoustically transparent membrane that blocks wax and debris from entering the receiver without compromising sound quality.

The difference from traditional wax guard systems is that EasyGuard does not need to be replaced. Instead of swapping a filter on a schedule and hoping the replacement goes smoothly, the wearer simply wipes the surface clean. Phonak's data indicates this approach can reduce service visits related to receiver issues by up to 38 percent.

For wearers, the significance is not just convenience. It is reliability. A hearing aid that keeps working without interruption, maintenance visits, or the mild anxiety of a filter replacement not going quite right is a hearing aid that does its job the way it was meant to: quietly, consistently, and completely in the background.

Bluetooth Connectivity: One Step, Both Ears, Every Device

The Audéo Infinio Ultra connects via Bluetooth to both iPhone and Android devices, streaming calls, music, podcasts, navigation audio, and all content directly to both ears without any intermediary device.

The Ultra update introduced one-step Bluetooth pairing, eliminating the multi-step connection process that older platforms required. For Android users, this means the same frictionless setup experience that iPhone users have had. Pairing is fast, and connection is stable across the real-world distances of a typical day: phone in a bag, tablet across the room, computer at a desk.

Hands-free calling works as described. The hearing aids capture the wearer's voice and transmit it during calls. The phone stays wherever it is. Both ears receive the call audio clearly. For people who have spent years managing phone calls by pressing a handset awkwardly against a device worn behind the ear, or who have avoided calls because the acoustic experience was unreliable, this is a meaningful change in what phone communication feels like.

myPhonak App: Control, Health Tracking, and Remote Care

The myPhonak app gives wearers complete personal control over their hearing experience from a smartphone. Volume adjustment, program selection, sound profile customization through equalizer presets and manual sliders, and noise reduction settings are all directly accessible.

Beyond hearing control, select features within the app's Health section track steps, distance, wearing time, activity levels, and heart rate, turning the hearing aid into a device that contributes to a broader picture of daily wellness. For wearers managing tinnitus alongside hearing loss, sound support tools are included.

Remote care functionality allows a hearing care professional to make fine-tuning adjustments through the app without requiring a clinic visit. As hearing needs change with seasons, health, or environment, the ability to access expert support without scheduling and traveling to an appointment is a practical benefit that wearers notice quickly.

A Find My Hearing Aids feature, added in late 2024, helps locate misplaced devices through the app, solving a problem that most hearing aid wearers have encountered at least once.

Roger Wireless Microphone Compatibility

The Infinio Ultra is fully compatible with Phonak's Roger wireless microphone range, including the Roger On, Roger Select, Roger Touchscreen Mic, and Roger Table Mic. Roger technology has been shown in independent research to significantly improve speech understanding in noise and over distance, beyond what any hearing aid microphone can achieve on its own.

For wearers navigating large meeting rooms, classrooms, lecture halls, or any environment where the speaker is far away or the background noise is heavy, a Roger microphone placed near the source delivers a direct, clear signal regardless of distance or acoustic conditions. For many wearers, Roger integration is the feature that makes the most demanding professional and educational environments accessible in a way that nothing else can match.

TV Connector and Extended Accessory Ecosystem

The Phonak TV Connector streams television audio directly into both hearing aids at broadcast quality, eliminating the disconnect between TV volume that works for everyone in the room and TV volume that actually allows the wearer to follow what is being said. Setup is straightforward, and the stream is automatic whenever the wearer is in range.

The broader Phonak accessory ecosystem, including the PartnerMic for one-to-one conversations in noise and the RemoteControl for wearers who prefer a dedicated physical control rather than a smartphone app, extends what the Infinio Ultra can do in the specific situations where wearers most need support.

IP68 Durability: Built for the Day as It Actually Happens

The Audéo Infinio Ultra carries an IP68 rating, which means full protection against dust and resistance to water submersion. For a device worn throughout every waking hour in every kind of weather and activity, this is not an optional extra. It is a baseline requirement for a hearing aid that is genuinely meant to be worn and forgotten rather than carefully managed.

Sweat during exercise, rain during a walk, humidity, and the ordinary moisture demands of daily life are handled without concern. The wearer does not need to think about protecting the device. The device handles that itself.

Who the Audéo Infinio Ultra Is For

The Infinio Ultra was built for people who want a premium hearing aid that works. Not a hearing aid that works when the room is quiet or the speaker is close or the settings have been manually adjusted to match the moment. A hearing aid that works in the restaurant, the meeting, the car, the backyard, the family gathering, and the phone call, without asking the wearer to do anything except be there.

It suits mild to severe hearing loss and is available at multiple technology levels, allowing wearers to choose the level of performance that fits their lifestyle and listening demands. At every level, the core of the platform, the AutoSense OS 7.0 intelligence, the rechargeable battery, the Bluetooth connectivity, and the IP68 durability, is present and fully operational.

It is the hearing aid for people who have spent enough time managing their hearing and are ready for a device that manages itself.

The Measure That Matters

The specification sheet of the Audéo Infinio Ultra is genuinely impressive. The AI precision figures, the battery efficiency gains, the Bluetooth standard, the IP rating, all of it reflects a device built to the highest standards available in hearing technology today.

But the real measure is different. It is the moment at a dinner table when the wearer realizes they have followed the entire conversation without once calculating where to sit, who to face, or how loud the room is. It is the end of a long social day when the exhaustion that used to come from listening hard simply is not there.

That is what the Phonak Audéo Infinio Ultra was built to give back. Ask your hearing care professional to let you try it in the environments where hearing has always been hardest. The answer will be in that experience, not on this page.
