Buying guidance
Is the EON Sphere E90 a strong fit for your routine?
E90 is the top technology level in the EON Sphere family. It is best suited to people who regularly spend time in the situations hearing aids find hardest: restaurants, group tables, meetings, and rooms full of competing voices.
A strong fit if you
- Spend real time in restaurants, meetings, groups, or family gatherings
- Want Phonak's dedicated AI processing for speech in loud noise, running automatically
- Prefer a rechargeable routine over buying and changing batteries
- Want direct streaming and calls from a compatible iPhone or Android phone
Consider another model if you
- Spend nearly all of your time in quiet, one-to-one conversation — a lower Sphere level or the Audéo EON R family may serve you at a lower price
- Have single-sided hearing and need a CROS setup — CROS is available with the Audéo EON R, not the EON Sphere
- Prefer disposable batteries — the EON Sphere family is rechargeable only
Compare other Phonak hearing aids or ask our hearing professionals which model fits your audiogram and routine.
HYPERSONIC AI chip
How does the E90 handle a noisy restaurant?
Most hearing aids process every environment on one chip. The EON Sphere adds a second, dedicated AI chip — HYPERSONIC — whose only job is separating speech from noise. It runs Spheric Speech Clarity 3.0, Phonak's most advanced speech-in-noise processing, so voices stay clear when the room gets loud.
You do not have to manage any of it. AutoSense OS AI 8.0 identifies the kind of environment you are in and, on the E90, turns on Spheric Speech in Loud Noise automatically when the noise builds — then turns it off again when things quiet down.
- Spheric Speech Clarity 3.0
- AI processing trained to lift conversation out of surrounding noise, delivered by the dedicated HYPERSONIC chip.
- Speech Enhancer
- An E90-level feature that gives soft speech extra emphasis in calm settings, useful for quiet talkers at a distance.
- WindBlock 2.0
- Reduces wind noise outdoors, so conversation stays easier on walks, bike rides, and breezy patios.
Interactive listening demonstration
Hear what AI noise processing changes
Reading about speech in noise only goes so far. Play Phonak's simulated busy scene, then switch between AI Off and AI On while it continues — the demo picks up from the same moment, so you hear exactly what the processing changes. Use headphones or good speakers.
Press play, then switch between AI Off and AI On at any moment. The scene keeps playing from the same point so you can compare fairly.

From morning to night
What does a full day with the E90 look like?
-
7:00 AM
Off the charger, set for the day
A full charge takes 2.5 hours and is rated for 29 hours of expected use — up to 38 hours maximum depending on streaming, features, and battery condition.
-
8:30 AM
Calls and podcasts on the commute
Audio streams directly from a compatible iPhone or Android phone. Hands-free calling is supported on compatible devices, so you can answer without reaching for the phone.
-
12:30 PM
Lunch in a loud restaurant
AutoSense OS AI 8.0 recognizes the noise and the E90 engages Spheric Speech in Loud Noise automatically, putting the HYPERSONIC chip to work on the conversation in front of you.
-
4:00 PM
A windy walk without the roar
WindBlock 2.0 works on wind noise outdoors, and the IP68-rated housing is tested against dust and water exposure for everyday conditions.
-
10:00 PM
Back on the charger overnight
Drop both hearing aids into the charger before bed. If you ever need a quick top-up during the day instead, about an hour of charging restores over half the battery.
Rechargeable power
How long does the battery actually last?
Phonak rates the EON Sphere at 29 hours of expected operating time on a full charge, with a maximum of up to 38 hours. Where you land in that range depends on how much you stream, which features are active, the environments you spend time in, and the age of the battery.
Charging takes 2.5 hours for a full charge, about 2 hours to 90%, and about 1 hour to 55%. Your order includes Phonak's Premium ChargerGo, a portable case with its own internal battery rated for up to three full recharges away from an outlet. The EON Sphere is also compatible with Phonak's plug-in Charger RIC E if you want a simple desk charger at home.
The Premium ChargerGo is the portable charger that ships with the EON Sphere. Phonak's plug-in Charger RIC E is also compatible if you prefer a desk charger without a built-in travel battery.
Bluetooth and app control
How does it connect to your phone and TV?
The EON Sphere supports both Bluetooth Classic Audio and the newer Bluetooth LE Audio standard, including Auracast broadcast audio. It works with a wide range of current phones, and it can join Auracast broadcasts in venues that offer them.
Direct streaming and calls
Stream calls, music, podcasts, and video audio from compatible iPhone and Android devices. Hands-free calling depends on your phone's compatibility.
Auracast-ready
Join compatible Auracast broadcasts in public venues as availability grows — no extra receiver needed when the transmitting venue supports it.
myPhonak app
Adjust volume and programs discreetly from your phone, and access supported remote features through the myPhonak app.
TV Connector
The optional TV Connector accessory streams television audio directly to both hearing aids at your own volume.
Roger microphones
Compatible with Phonak's Roger microphone portfolio for lectures, large meetings, and times when the person speaking is farther away.
PartnerMic and remote
A clip-on PartnerMic for one-to-one distance listening and a simple RemoteControl are also available.
Technology levels
E90 vs E70 vs E50: which Sphere level do you need?
Every EON Sphere level includes the HYPERSONIC chip and Spheric Speech Clarity 3.0. The difference is how much of that help arrives on its own — and how much you manage yourself when a room gets loud.
| Feature | E90 (this product) | E70 | E50 |
|---|---|---|---|
| Spheric Speech Clarity 3.0 | Included | Included | Included |
| Spheric Speech in Loud Noise | Automatic | Automatic | Manual program |
| Speech Enhancer | Included | Not included | Not included |
| Fine-tuning channels | 20 | 20 | 16 |
| Best for | Frequent noise, meetings, groups | Busy routines with regular noise | Everyday routines, occasional noise |
If you need CROS support for single-sided hearing loss, or want a simpler technology level, consider the Audéo EON R family, which starts at the essential E30 level.
Comfort and durability
How discreet is it behind the ear?
The EON Sphere body measures 28.7 mm tall and weighs 2.4 grams, designed to sit lightly and discreetly behind the ear. A thin receiver wire carries sound into the ear canal, and five receiver strengths let one design cover mild through profound hearing losses.
The housing is IP68 rated: tested for 60 minutes in 1 meter of fresh water and 8 hours in a dust chamber. That covers rain, sweat, and daily life — but it is protection, not an invitation to swim with them.

Common questions
Phonak Audéo EON Sphere E90 questions, answered
What makes the EON Sphere E90 different in noisy places?
The EON Sphere carries a dedicated HYPERSONIC AI chip that runs Spheric Speech Clarity 3.0, Phonak's most advanced speech-in-noise processing. On the E90 level, AutoSense OS AI 8.0 engages that support automatically when it detects loud, complex noise, so you get the help without changing programs yourself. Results still depend on your hearing loss, fitting, and environment.
How long does the battery last on one charge?
Phonak rates the EON Sphere at 29 hours of expected operating time, with a maximum of up to 38 hours depending on streaming, active features, environment, and battery condition. A full charge takes 2.5 hours, and about one hour of charging restores 55% of the battery.
Will it work with my iPhone or Android phone?
Yes, with compatible devices. The EON Sphere supports Bluetooth Classic Audio plus Bluetooth LE Audio and Auracast, which covers direct streaming from compatible iPhone and Android phones. Hands-free calling, LE Audio, and Auracast each depend on your specific phone model and operating system, so check Phonak's current compatibility information for your device.
What is the difference between the E90, E70, and E50 levels?
All three levels include the HYPERSONIC chip and Spheric Speech Clarity 3.0. The E90 gives you the most help automatically and adds Speech Enhancer, which lifts soft voices in quiet rooms. The E70 also switches into its loud-noise support on its own, with fewer of the E90 refinements. With the E50, you switch to the loud-noise program yourself when you need it, and fine-tuning uses 16 channels instead of 20.
How is the EON Sphere different from the Audeo EON R?
Both are rechargeable receiver-in-canal hearing aids on Phonak's EON platform, with the same size, weight, and battery ratings. The Sphere adds the dedicated HYPERSONIC AI chip with Spheric Speech Clarity 3.0 for clearer conversation in loud noise. The Audeo EON R also offers a simpler essential technology level (E30), and if you need a CROS setup for single-sided hearing loss, the EON R is the model that supports it.
Is the EON Sphere E90 waterproof?
No. It is IP68 rated, which means it was tested for 60 minutes in 1 meter of fresh water and 8 hours in a dust chamber. That protects against rain, sweat, and daily exposure, but the hearing aids should not be worn for swimming or showering.
Do I need a smartphone to use these hearing aids?
No. The E90 works fully as a professionally fitted hearing aid without any phone. A compatible smartphone adds streaming, hands-free calling on supported devices, and discreet adjustments through the myPhonak app.
Which charger comes with the EON Sphere E90?
Your order includes the Premium ChargerGo, Phonak's portable charging case with an internal battery rated for up to three full recharges away from an outlet. A full charge takes 2.5 hours. The EON Sphere is also compatible with Phonak's plug-in Charger RIC E if you prefer a desk charger at home.
