What's current? | Phonak EON | Phonak Ultra | Virto Infinio hearing aids | Other useful information | Conclusion and key takeaways
Last Hearing Aid UK Update: 22
Phonak's newest hearing aid platform, EON, launched in the UK in September 2026 and is now the current flagship, built around a new dedicated AI chip for separating speech from background noise.
The previous flagship, Infinio Ultra Sphere, remains a great option, alongside the Infinio Ultra R and the custom-fit Virto Infinio range. Hearing Aid UK supplies and professionally fits all Phonak ranges throughout the UK, in clinic or via a free home visit.
Phonak's current ranges now sit across three ranges: the new EON platform, the Infinio Ultra range, and the Virto Infinio custom-made models for people who want discreet In-the-Ear options.
Here's what's current in the EON range:
Phonak states EON Sphere is 25% smaller and 20% lighter than the previous Sphere generation, and offers up to 38 hours of battery life on a single charge.
Here's what's current in the Infinio Ultra range:
Both models feature AutoSense OS 7.0, which Phonak states is 24% more precise than the previous generation at recognising your listening environment and adjusting accordingly.
Here are the current Virto Infinio custom ranges:
Recently discontinued Phonak ranges:
Audeo Infinio and Audeo Infinio Sphere, launched in August 2024, were replaced by the Infinio Ultra range in October 2025. Infinio Ultra Sphere itself was Phonak's flagship until EON launched in September 2026, and remains a strong, more accessible alternative to it.

Spheric Speech Clarity 3.0, which separates speech from background noise using the new HYPERSONIC chip, and AutoSense OS AI 8.0, which reads the wider listening environment and decides which processing features to engage. Phonak states this makes EON Sphere's chip 37% more efficient than the previous generation running the older Spheric Speech Clarity 2.0.
EON Sphere is built for people who regularly find speech-in-noise genuinely difficult: restaurants, family gatherings, busy workplaces. EON R carries the same scene intelligence and connectivity in a more accessible model, without the dedicated speech-separation hardware, for people whose listening challenges are less demanding day-to-day.

"EON is a genuine step forward, not just a smaller version of what came before. But Infinio Ultra Sphere isn't obsolete overnight; it's still excellent technology, and for a lot of people the real-world difference won't be worth the price gap.
It comes down to being honest about how often you're actually struggling, not chasing the newest name."
says Paul Harrison, Audiology Expert & Founder, Hearing Aid UK

The Infinio Ultra Sphere isn't just a marketing claim about AI; it genuinely has dedicated hardware that most hearing aids don't. The DEEPSONIC chip does nothing but work on separating speech from background noise in real time.
Traditional hearing aids use directional microphones that focus on what's in front of you. The Sphere's AI can extract speech from any direction - behind, beside, in front - and handle multiple speakers simultaneously.
Phonak's research suggests you're three times more likely to understand every word in noisy environments compared with not having this technology. Available in technology levels i90 and i70 only.

The Ultra R offers sophisticated automated performance using the same AutoSense OS 7.0 technology, enhanced Bluetooth connectivity, and strong battery life, without the dedicated AI hardware. Available in four levels: i90, i70, i50 and i30, with i90 and i70 offering the fullest feature set.

The Virto Infinio range brings the ERA platform technology to custom-made, In-the-Ear designs. These are moulded specifically to fit your ear canal, so they're as discreet as hearing aids get without being completely invisible.
Your audiologist takes an impression of your ear canal (or uses digital scanning), and the hearing aid is manufactured to precisely fit your ear.
This means better comfort and a more secure fit than universal receivers, but it also means you can't just swap them out if something goes wrong; they're specific to your ears.

The titanium model uses medical-grade titanium for the shell, which is both ultra-strong and 50% thinner than traditional acrylic. This allows for an even smaller, more discreet fit whilst maintaining durability.
Custom-made In-the-Ear aids sit in your ear canal, which means they're more prone to issues with earwax and moisture. They also can't include some features that Behind-the-Ear models offer, such as a telecoil option.
The Titanium models use size 10 batteries, which are the smallest available and might be fiddly if you have poor dexterity. But if visibility is your primary concern, and you're willing to accept these trade-offs, the Virto Infinio range offers impressive technology in a genuinely discreet package.

If you're reading this on behalf of a parent, partner, or friend who's struggling with hearing loss, you're doing them a genuine favour by taking the time to understand what's available.
The best next step is booking a consultation with one of our audiologists, either in the clinic or in the comfort of home. You're welcome to attend with them.
Many family members find it helpful to be there for the discussion, and audiologists appreciate having someone who can provide insight into real-world hearing challenges.
There's no obligation, and it's an opportunity to understand what current technology can actually achieve rather than relying on marketing claims.
Phonak's current ranges genuinely aren't one-size-fits-all. EON Sphere is the newest and most capable option for people who regularly struggle in noisy, multi-speaker environments. Infinio Ultra Sphere remains a strong, more accessible alternative with the same core speech-separation approach.
The Ultra R and EON R both offer excellent everyday performance without the dedicated AI hardware, and Virto Infinio models offer discretion for people who prioritise invisibility.
The key is being honest about where you actually struggle with hearing, not choosing technology because it's the newest name. If you're uncertain which model suits your needs, our audiologists can provide genuinely independent advice based on your specific situation.

Phonak's current lineup spans two generations of speech-in-noise technology: the new EON platform and the Infinio Ultra range before it.
Both offer personalised sound settings, smartphone connectivity, and effective noise reduction, suited to a range of listening environments.
Most models are rechargeable, so you can pop them on charge overnight, and you can fine-tune your settings yourself through the myPhonak app. If you'd like more information about any of the current Phonak ranges, please contact us free on 0800 567 7621.
Phonak EON Sphere vs Phonak Infinio Ultra Sphere
Rugged Hearing Aids
How long do hearing aids last? Do not spend hundreds of pounds without getting a second opinion from us.
Not only are the prices great, but the service is fantastic! Many thanks to your team.The newest Phonak hearing aids are the Phonak Audéo EON range, launched in the UK in September 2026 in two versions: EON Sphere and EON R.
They sit alongside Phonak’s previous flagship, Infinio Ultra, and the custom in-ear Virto Infinio, which are both still current.
Phonak EON Sphere includes a dedicated chip that Phonak states is designed to separate speech from background noise, while EON R shares the same AutoSense OS AI 8.0 sound processing and connectivity without that extra chip.
EON Sphere comes in E90, E70 and E50 technology levels, and EON R comes in E90, E70, E50 and E30, so EON R gives more choice for quieter lifestyles and tighter budgets.
Hearing Aid UK supplies and professionally fits Phonak EON Sphere and Phonak EON R throughout the UK. Each pair is fitted and fine-tuned in person by an HCPC-registered audiologist, either at one of our 93+ local clinics or during a free home visit.
