What makes it special

Many things worth knowing about this hearing aid

Specs only tell you so much. Here's what's actually worth knowing about the Phonak Audéo EON E90 Sphere — what each feature does, and why it matters day to day.

🤖

ERA + Hypersonic (Dual-chip) Chipset

The Audéo EON Sphere uses unique dual chip technology: the ERA chip plus HYPERSONIC, a dedicated real-time AI sound processing chip (Sonova International). This powers your EON Sphere 90 and 70.

📱

Roger Direct
Bluetooth
Auracast Connectivity

Connect straight to your phone, TV, and other devices — calls, music, and shows stream right into your ears. No extra remotes or accessories to carry around.

📡

Auracast Ready

Stream airport announcements, gym TVs, theater audio directly to your ears. The future is here.

🔋

38 hrs Battery Life

Two full days per charge. Weekend trips without the charger? Finally possible.

💧

1m Water Resistant

Rain, sweat, splashes. Golf in the rain? Go for it.

📱

Premium Technology level

Higher tiers do more of the work for you — automatically taming background noise and adjusting to busy rooms so speech stays clear. Lower tiers cover the basics and lean more on manual adjustments.

🔋

Rechargeable Battery Type

Rechargeable, just like your phone. Set them in the case overnight and wake up to a full day of power — no tiny batteries to swap, fumble with, or keep buying.

⚕️

HSA / FSA Eligible

Hearing aids count as a qualified medical expense, so you can pay with pre-tax HSA or FSA dollars. Use your HSA/FSA card right at checkout, or file the receipt with your plan for reimbursement.

⚡

Recharging Case

The case carries its own battery, so it tops off your hearing aids two to three times before it ever needs an outlet. Just drop them in, close the lid, and charging starts on its own.

Spheric Speech Clarity 3.0

Follow Every Conversation—Even When Multiple People Are Talking

Family dinners. Crowded restaurants. Rooms where three conversations happen at once. Spheric Speech Clarity 3.0 separates voices from background noise automatically and instantly — identifying and focusing on the people speaking, whether they're beside you, across the table, or even behind you. You're up to 2x more likely to understand every word, from any direction.

No manual adjustments. No switching programs. Just the conversation.

Life with Spheric Speech Clarity:

  • Enjoy clear speech in restaurants, with voices automatically separated from background noise.
  • Follow along when three conversations are happening at once.
  • Hear voices from any direction — beside you, across the table, or behind you.
  • Powered by the new HYPERSONIC chip — a dedicated AI processor that does the work for you.

    Crowds and Live Events

Platform Comparison

The biggest Phonak upgrade in years

EON is Phonak's newest platform. Every model runs the new ERA chip, AutoSense OS AI 8.0, and WindBlock 2.0 — and EON Sphere adds the HYPERSONIC AI chip with Spheric Speech Clarity 3.0. Here's exactly what changed from the last generation.

Highlights of what's new:

  • 25% smaller and 20% lighter — the smallest Sphere Phonak has ever made
  • WindBlock 2.0 — 95% of wearers said it took the effort out of listening outdoors
  • Auracast™ broadcast audio — tune into airports, theaters, and TVs that broadcast sound
  • Up to 38 hours of battery life on a single charge

    Improved speech in noise, TV sound better. Takes awhile to adjust to them and they are instruments, so learning how to use them is important. So far, I am very pleased with my purchase.

    Best, by far, of the 3 hearing aids I've tried

    If you're looking for full functionality in a hearing aid, this one, in my opinion rates very high! It's easy to use, it sounds very good and offers a wide variety of functionality beyond excellent improvment in your hearing ability.
