OVERVIEW

Product Information

The Phonak Audéo EON Sphere is the most advanced hearing aid in the Audéo EON family, built for people who live in complex, demanding sound environments. Powered by the new HYPERSONIC AI chip and the EON platform's AutoSenseOS AI 8.0, it continuously reads the acoustic scene and adjusts every processing parameter automatically, without any input from the wearer.

Spheric Speech Clarity 3.0 gives the EON Sphere true all-around clarity, separating speech from background noise in real time from any direction, not just in front of the wearer. WindBlock 2.0 automatically cuts wind noise by up to 50 dB, and the HYPERSONIC chip runs 37% more efficiently than the previous generation while packed into a body that's 25% smaller and 20% lighter, for a device that disappears both acoustically and physically.

With up to 38 hours of rechargeable battery life and universal Bluetooth connectivity, the Audéo EON Sphere connects to virtually any Bluetooth-enabled device, with hands-free calling and direct streaming of calls, music, and TV audio to both iPhone and Android. Auracast support lets wearers tap into broadcast audio in supported public and shared spaces, and the myPhonak app puts full remote control in their hands. EasyGuard domes seal out earwax to help the device hold up to daily wear, and it's available in eight finishes to match any style.

Every BLUEMOTH purchase includes a free home trial, unlimited telehealth audiologist sessions, and a 45-day satisfaction guarantee.

Frequently Asked Questions

Extend the Phonak Audeo Eon E90-Sphere

Compatibility varies by model. Most hearing aids in our catalog connect directly to iPhone (iOS 14 and newer) and Android phones (Android 10 and newer) via Bluetooth Low Energy for direct streaming of calls, music, and audio. Check the Technical Specifications table above for compatibility details specific to this model, or contact our audiologists at BLUEMOTH for confirmation.

Start with the Experience Box — three premium hearing aids shipped directly to your home. A licensed BLUEMOTH audiologist guides you through the fitting process via telehealth. You wear each device in your real everyday environments for several days and provide feedback. Your audiologist then recommends the best match for your hearing profile. No commitment, no clinic visit, no pressure until you are completely sure.

Most hearing aid brands offer entry, mid, and premium tiers. All tiers share the same form factor and core technology. The difference is processing power — premium tiers deliver more processing channels, more advanced noise reduction, and better performance in challenging listening environments like crowded restaurants or noisy offices. Entry and mid tiers perform excellently for quieter, less demanding listening needs. Our audiologists can help you choose the right tier for your lifestyle.

BLUEMOTH offers a 45-day trial period from the date of delivery. Hearing aids must be returned in original condition with all included accessories. To start the return process, contact us at hello@bluemothhearing.com. Your satisfaction is fully guaranteed.
