Phonak Hearing Aids
How Phonak Hearing Aids Think for You
Phonak hearing aids are built around one idea. The device should notice the room changed before you do, and adjust without being asked.
That system is called AutoSense OS. It listens continuously, works out what kind of environment you are in, and blends the right programs together. Quiet living room. Noisy restaurant. Windy walk. Car with music on. You are not switching anything by hand.
We carry three Phonak platforms. This page explains what separates them and which models sit on each.
The Chips: HYPERSONIC, DEEPSONIC and ERA
What a Phonak can do comes down to how many processors it carries.
Every current Phonak runs the ERA chip. ERA handles the sound processing and the connectivity, and it is the chip that made universal Bluetooth work. That is why a Phonak pairs with an iPhone, an Android tablet and a Windows laptop with nothing in between.
The Sphere models add a second chip whose only job is separating speech from noise, working in real time alongside ERA. On the EON Sphere that chip is HYPERSONIC. On the Infinio Ultra Sphere it is DEEPSONIC, the generation before it.
Models without a second chip run ERA alone. They handle everyday listening well and give up ground in the loudest rooms, which is exactly what the second chip is for.
The oldest platform we carry, Lumity, runs PRISM.
AutoSense OS, by Platform
Not every Phonak Audéo runs the same version of AutoSense OS. The Audéo EON runs AutoSense OS 8.0, the newest of the group. The Audéo Infinio Ultra runs 7.0. Within the Lumity line, the L90 and L70 run 5.0, while the L50 and L30 run 4.0.
Each step up scans your surroundings more often and sorts them into more environments. The hearing aid reacts faster, and with more nuance, as you move between a quiet room, a noisy restaurant and the car.
Sphere Mode
Sphere Mode is the second chip doing its one job. On the EON Sphere and the Infinio Ultra Sphere, a dedicated processor separates the voice you want from the noise around it, in real time, while ERA handles everything else.
On the E90 Sphere and E70 Sphere it runs automatically at full strength. On the E50 Sphere you switch it on yourself from the myPhonak app, at moderate strength.
In Phonak's field study, participants were up to three times more likely to catch every word from any direction with the mode active, and rated their listening effort lower on a standardized scale. Less strain in the conversation, more left at the end of the day.

The SmartSpeech Technology Suite
Every Phonak hearing aid in the current lineup runs SmartSpeech Technology, a set of features that work together to find and enhance speech across different environments.
These features switch on by themselves based on where you are. On the EON Sphere and the Infinio Ultra Sphere, they run alongside the dedicated AI chip. On the EON R, the Infinio Ultra R and the Lumity line, SmartSpeech handles speech enhancement on its own.
Hands-Free Calling on Android, Not Just iPhone
Most hearing aids that claim "universal connectivity" have an asterisk in the fine print. Full hands-free calling works on iPhone. Android gets streaming, maybe, and hands-free calling "may require an additional accessory."
Phonak handles it at the chip level instead. Every current Phonak runs the ERA chip, which takes calls and audio straight from the device whatever the operating system. If you have spent years carrying a separate microphone just to use your own phone, that is the part that changes.

Phonak Model Guide: Which One Is Right for You?
-
The newest platform, and the one that does the most work for you. Two chips: HYPERSONIC for separating speech from noise and ERA for everything else. It runs 25% smaller and 20% lighter than the generation before it, with up to 38 hours of battery. Right for anyone who spends real time in loud rooms and would rather not think about it.
Compare the E90 Sphere, E70 Sphere and E50 Sphere.

-
The previous platform, and the battery champion of our whole Phonak lineup. Up to 56 hours on a charge, against 38 on the newest EON Sphere, with DEEPSONIC handling the AI speech separation. If runtime is what decides it for you, this is the one, and it costs less than the newer platform. Two levels, the I90 and the I70.

The myPhonak App: Remote Control, Health Tracker, Direct Line to Your Provider
The myPhonak app is where the day-to-day experience lives for most users:
- Volume and program control without touching the hearing aids
- Custom programs for specific environments you can name and save
- Equalizer to tune bass, mid, and treble to your preference
- StereoZoom strength adjustment when you need to focus on one voice
- Find My Hearing Aids with GPS-assisted real-time guidance
- Remote Support for appointments with your hearing care provider
On a Sphere model, the app also gives you direct control over Sphere Mode and noise reduction strength, so you decide how hard the AI works in any given room. On the E90 and E70 Sphere it runs automatically and the app is there when you want it. On the E50 Sphere, the app is where you switch it on.
Roger Accessories: When the Hearing Aids Need Backup
Most users won't need accessories immediately. The Phonak lineup handles the vast majority of listening situations on its own. For situations that stay hard, Roger wireless microphones send speech straight to your hearing aids over RogerDirect. Phonak built the receiver into the hearing aid, so there is no extra hardware to buy.
| Accessory | Best For |
|---|---|
| Roger On | Group conversations, lectures, versatile tabletop or handheld use |
| Roger Select | Tables where multiple people are speaking; auto-follows the active speaker |
| Roger Clip-On | Worn by your conversation partner for direct one-on-one voice transmission |
| TV Connector | Streams TV audio directly to both hearing aids; room volume stays separate |
| PartnerMic | Noisy restaurant or outdoor conversations with a companion |

Why Buy Phonak Hearing Aids Through Injoy
Phonak doesn't sell directly to consumers. Every purchase goes through a retailer or clinic. The question isn't whether you'll buy from someone. It's whether you're paying for a waiting room you don't need.
As an authorized Phonak retailer, we provide genuine devices, valid manufacturer warranties, and licensed hearing care providers who handle your fitting using the same software traditional clinics use. Your hearing aids are programmed to your audiogram before they ship. Adjustments happen on your schedule, from wherever you are.
Every Phonak purchase through Injoy includes authentic, brand-new devices from an authorized retailer, licensed hearing care provider fitting and remote programming, unlimited remote adjustments with no time limits and no session caps, a 60-day risk-free trial with a full refund if they are not right, a 4-year manufacturer warranty, 3-year loss and damage coverage, and phone support from people who know the whole catalog.
The hearing aids are identical to what any clinic sells. The professional care is identical. The price is not. That's the Injoy difference.
Before you decide...
What to Know Before You Buy Phonak Hearing Aids
Are these authentic Phonak hearing aids or refurbished models?
Brand-new, authentic Phonak devices sourced directly through official manufacturer channels. Your warranty is valid with the manufacturer directly, not voided the way it would be through an unauthorized seller. We're an authorized Phonak retailer, which means full manufacturer support from day one.
How does remote programming compare to in-person clinic appointments?
The software is identical. Our licensed hearing care providers use the same manufacturer programming tools any clinic uses. Many users find remote adjustments more effective because you're wearing the hearing aids in your real listening environments during the session, not sitting in a soundproof booth.
What's the difference between the Sphere Infinio Ultra and Infinio Ultra R?
What's the difference between the Sphere Infinio Ultra and Infinio Ultra R?
The Sphere Infinio Ultra carries two chips: DEEPSONIC for dedicated AI speech separation and ERA for standard processing. The Infinio Ultra R has ERA alone. In everyday listening the difference is subtle. In a crowded restaurant or a large event, the dedicated chip produces noticeably clearer speech. The R is smaller and lighter, and it runs up to 31 hours against the Sphere's 56.
Does Phonak work with Android phones for hands-free calling?
Yes, with no accessories. Current Phonak models support full hands-free calling on compatible Android phones, the same as on iPhone, because the ERA chip takes the call directly from the device. No StreamLine Mic, no clip-on transmitter, nothing extra to carry.
How long does the Sphere Infinio Ultra battery actually last?
Up to 56 hours on a charge, which is the longest runtime in the Phonak lineup we carry. Heavy streaming and constant AI use will bring that down, the way they do on any hearing aid. It also supports quick charging when you need a top-up before dinner.
Do I need Roger accessories right away?
No. Start with the hearing aids alone. The Roger system is for situations that remain challenging after the hearing aids are well fitted, large conference rooms, lectures, or outdoor events with significant noise. Most users never need accessories. If you find you do, our team can help you identify the right Roger mic for your specific situation.
What if the hearing aids don't work for me?
Return them within 60 days for a full refund. No restocking fees. Test them in real life, restaurants, family dinners, phone calls, TV, not just around the house. If they don't deliver, send them back.
Are Phonak hearing aids suitable for severe hearing loss?
Yes, depending on the model and the receiver. Phonak offers four receiver powers: standard for mild to moderate loss, medium for mild to moderately severe, power for moderate to severe, and ultra power for severe to profound. Your audiogram decides which one, and our licensed hearing care providers handle that during the fitting.
What does Auracast-ready mean on Phonak devices?
Auracast is a Bluetooth standard that allows hearing aids to connect directly to public broadcast systems, airport announcements, theater audio, stadium PA systems. Current Phonak Infinio models have the hardware built in, with full activation coming through a firmware update. When that update rolls out, your hearing aids receive it automatically.
What's included in the 60-day trial?
Everything. You receive your fully programmed hearing aids, wear them across all your real listening situations, and schedule remote adjustment sessions as needed. If they're not right for any reason at the end of 60 days, return them for a complete refund. No restocking fees, no complicated process.
