Phonak Audéo EON Sphere E70: advanced help for active, social days

Audéo EON Sphere E70 is built for people whose week regularly moves from one-to-one conversation into meetings, restaurants, and group gatherings. Its dedicated HYPERSONIC AI chip powers Spheric Speech Clarity 3.0, and the E70 can bring its loud-noise program into the automatic listening mix. You also get rechargeable use, direct streaming from compatible phones, and 20 fine-tuning channels for professional fitting.

Buying guidance

Who gets the most value from the E70 level?

E70 sits between the premium E90 and standard E50. It is a practical match when difficult conversations happen often enough that automatic Sphere support matters, but you do not need every refinement reserved for the top level.

A strong fit if you

  • Move often between quiet rooms, traffic, meetings, restaurants, and group conversation
  • Want Spheric Speech in Loud Noise available automatically instead of selecting it yourself
  • Value SpeechSensor, StereoZoom 2.0, and Dynamic Noise Cancellation for complex settings
  • Need rechargeable hearing aids with streaming from compatible iPhone and Android devices

Compare another level if you

  • Want the broadest Sphere feature set, including Speech Enhancer for soft or distant speech in quiet — compare E90
  • Only occasionally enter loud settings and are comfortable choosing an additional program — E50 may be enough
  • Need CROS for single-sided hearing — choose a compatible Audéo EON R model instead

Browse Phonak hearing aids or ask our hearing professionals to match the technology to your audiogram and routine.

HYPERSONIC AI chip

Automatic Sphere processing when the room gets busy

E70 pairs Phonak's everyday AutoSense OS AI 8.0 processing with a separate HYPERSONIC AI chip dedicated to speech in surrounding noise. Spheric Speech Clarity 3.0 uses that extra processing path when conversation has to compete with a loud room.

At the E70 level, Spheric Speech in Loud Noise can engage automatically. That makes E70 especially useful for listeners who regularly cross from calm settings into restaurants, receptions, meetings, and other unpredictable environments without wanting to stop and change programs.

Listen to the processing concept

Compare a busy scene before and after AI support

Use the two synchronized tracks to focus on the speaker while the surrounding crowd changes. This is a demonstration of the processing effect, not a prediction of an individual fitting; headphones make the contrast easier to hear.

Start with the untreated sound scene

The target voice shares attention with nearby talkers and room noise. Listen for how the background pulls focus away from the conversation.

An active-day example

How E70 follows a day that keeps changing

Person wearing a Phonak Audeo EON hearing aid during conversation
E70 is designed for listeners who encounter several different sound environments in the same day.
  1. 7:30 AM

    Begin with a full charge

    The hearing aids come out of the charger ready for 29 hours of expected operation, with up to 38 hours possible depending on use and battery condition.

  2. 9:00 AM

    Move from calls into a team meeting

    Compatible phones can stream calls directly, while AutoSense OS AI 8.0 adapts as the listening task shifts from personal audio to live conversation.

  3. 1:00 PM

    Meet friends in a lively café

    When the sound scene becomes sufficiently demanding, E70 can bring Spheric Speech in Loud Noise into its automatic mix and use the HYPERSONIC chip on the speech around you.

  4. 5:30 PM

    Walk outside in changing weather

    WindBlock 2.0 addresses wind noise, and the IP68-rated body is designed for everyday resistance to water and dust.

  5. 9:30 PM

    Finish the day away from an outlet

    The included Premium ChargerGo can recharge the hearing aids while traveling and carries power for up to three full device recharges.

Battery and charging

Power for long days, plus charging away from home

Phonak lists 29 hours as the expected operating time for Audéo EON Sphere and up to 38 hours as the maximum. Streaming time, active processing, listening environments, battery age, and the individual fitting all affect the result.

A complete charge takes 2.5 hours. If time is short, the battery reaches about 55% in one hour and 90% in about two hours. The included Premium ChargerGo has its own internal battery and can provide up to three full hearing-aid recharges before the case itself needs power.

Premium ChargerGo gives the E70 a familiar overnight routine and portable backup power for travel.

Prefer a charger that stays on a desk? The compatible Phonak Charger RIC E plugs into power and is available as an alternative accessory.

Use E70 with compatible personal devices, television accessories, and public broadcast sources.

Wireless listening

Keep calls, media, television, and app controls within reach

E70 supports Bluetooth Classic Audio as well as Bluetooth LE Audio and Auracast. That combination covers direct audio from many compatible iPhone and Android devices while preparing the hearing aids for supported broadcast-audio venues.

Phone calls and streaming

Send calls, music, podcasts, and video sound directly from compatible iPhone and Android devices. Hands-free calling depends on the phone.

Auracast broadcasts

Connect to compatible LE Audio broadcasts when a venue or transmitting device offers them.

myPhonak controls

Use the app for supported volume, program, and remote-care functions without reaching behind the ear.

Television listening

Add the optional TV Connector to stream TV sound to both hearing aids at a personal listening level.

Roger microphones

Extend access to a lecturer, presenter, or distant speaker with a compatible Roger microphone.

PartnerMic and RemoteControl

Choose a compact clip-on microphone for one speaker or a simple handheld remote for basic adjustments.

Check your device: Phone support is model-specific. Confirm the exact device and operating-system requirements for streaming, hands-free calling, LE Audio, and Auracast before ordering.

Technology levels

E70 is the advanced middle ground in the Sphere family

Choose the family for the kind of processing you need, then choose the level for how often your routine becomes complex. E70 is aimed at frequent busy-place listening with automatic Sphere support, while E90 adds the fullest refinements and E50 moves the Sphere loud-noise program outside the automatic mix.

What every Audéo EON level has in common

  • AutoSense OS AI 8.0 adapts to changing sound scenes.
  • Rechargeable power with 29 hours expected and up to 38 hours maximum runtime.
  • Bluetooth and Auracast support compatible phones, devices, and broadcasts.
  • WindBlock 2.0 manages distracting wind noise.
  • myPhonak and Roger add app control and compatible microphone options.

  • Purpose-built processing for speech in loud noise
  • Spheric Speech Clarity 3.0 at every Sphere level
  • E70 and E90 engage Spheric Speech in Loud Noise automatically
Broader choice and CROS support

Choose Audéo EON R for versatile everyday listening

  • E30, E50, E70, and E90 technology levels
  • Core EON processing with AutoSense OS AI 8.0
  • The EON choice when a CROS setup is required

Fit, size, and protection

A low-profile RIC body with a broad fitting range

The 2.4-gram EON Sphere body measures 28.7 by 12.6 by 8.9 mm and rests behind the ear. Sound travels through a thin receiver wire, keeping the main electronics out of the ear canal while allowing S, M, MAV, P, and UP receiver options.

Its IP68 rating is based on testing for 60 minutes in one meter of fresh water and eight hours in a dust chamber. That is useful protection for rain, perspiration, and routine exposure, but the hearing aids should still come off for swimming and showering.

Questions shoppers ask

Phonak Audéo EON Sphere E70 answers

Does EON Sphere E70 turn on its loud-noise AI automatically?

Yes. At the E70 level, Spheric Speech in Loud Noise can engage automatically through AutoSense OS AI 8.0 when the environment becomes demanding. The result still depends on your hearing loss, professional fitting, and the actual sound scene.

What does E90 add over E70?

E90 is the fullest Sphere level and adds Speech Enhancer for soft or distant speech in quiet, along with the highest listed settings for several premium features. E70 retains automatic Spheric Speech in Loud Noise, SpeechSensor, StereoZoom 2.0, Dynamic Noise Cancellation, and 20 fine-tuning channels.

How is E70 different from E50?

Both use the HYPERSONIC chip and Spheric Speech Clarity 3.0. E70 can place Spheric Speech in Loud Noise in the automatic mix and includes SpeechSensor, StereoZoom 2.0, and Dynamic Noise Cancellation. On E50, the Sphere loud-noise feature is an additional program and the fitting uses 16 channels.

What battery life should I expect?

Phonak lists 29 hours of expected operating time and up to 38 hours maximum. Streaming, enabled features, environment, battery condition, and the individual fitting can change the result. A full charge takes 2.5 hours.

Can E70 stream from both iPhone and Android?

It can stream from compatible iPhone and Android devices using Phonak's supported Bluetooth connections. Hands-free calling, Bluetooth LE Audio, and Auracast depend on the specific phone, operating system, or broadcaster.

Is Audéo EON Sphere E70 compatible with CROS?

No. Phonak lists CROS E-R compatibility with Audéo EON R, not Audéo EON Sphere. If you need a CROS setup for single-sided hearing, ask which EON R level fits your needs.

Can I use E70 without a smartphone?

Yes. It works as a professionally fitted hearing aid without a phone. A compatible smartphone adds direct streaming, supported calling features, app adjustments, and remote-care functions.

What charger is included?

The order includes Phonak's Premium ChargerGo, a portable charging case with an internal battery rated for up to three full hearing-aid recharges. The plug-in Charger RIC E is also compatible.
