Fortell AI Hearing Aids vs. Phonak Audéo EON

Fortell delivers the best background-noise performance we've seen, but its aggressive processing, lack of Android connectivity, and limited in-person clinic network are important tradeoffs.

The EON Sphere is one of the strongest hearing aids I’ve seen for speech performance, with exceptional results in background noise and a much smaller, more comfortable design than its predecessor.

Fortell AI Hearing Aids achieved a SoundScore of 6.0/5 and a SoundGrade of A in HearAdvisor lab testing. The Prescription Hearing Aid category average SoundScore was 4.19/5.

Phonak Audéo EON Sphere achieved a SoundScore of 5.0/5 and a SoundGrade of A in HearAdvisor lab testing. It ranked #1 of 39 Prescription Hearing Aid devices tested. The Prescription Hearing Aid category average SoundScore was 4.19/5.

Fortell AI Hearing Aids feel well built, though their IP54 rating offers less water and debris resistance than many prescription hearing aids, which commonly carry a higher IP68 rating. As with any hearing aid, regular cleaning and proper care will help keep them performing well over time.

Phonak Audéo E90 Sphere have an excellent build quality with a robust, portable charging case and a high ingress rating of IP68.

Fortell states that its hearing aids last around 24 hours per charge in the default All-day AI mode, so they should easily last a full day even if you rely heavily on the more processing-intensive “All voices” or “Front voices” programs.

Audéo EON offer around 38 hours of use per change, which is a decrease compared to the previous firmware-upgraded Sphere Ultra. Regardless, the battery life should span your entire day and a full recharge takes 3 to 4 hours, or 30-minute quick charge can provide an additional 6 hours of use.

While Fortell AI Hearing Aids support hands-free calling and audio streaming on iOS devices, they currently do not support Android, and the company has not announced a timeline for Android compatibility.

Phonak are compatible with both iOS and Android, offering wireless audio streaming and hands-free calls. Pairing was easy and reliable in our testing, especially with Apple mobile devices.

The Fortell app offers useful controls for volume, a 3-band EQ, and several AI listening modes. While I found it easy to use and sufficiently flexible, it is more limited than many competing apps, with no tinnitus features, health tracking, or other extras.

I found the MyPhonak Hearing Aid app easy to use with many useful features, including health and fitness tracking.

I found Fortell AI Hearing Aids comfortable and similar in fit to other prescription receiver-in-canal hearing aids. Although the body is slightly larger than many competing devices, it should fit comfortably behind most ears without interfering with glasses or causing retention issues. Your provider can help you fine-tune your fit in office.

EON are extremely comfortable with their smaller more compact redesign. Glasses wearers, and or those with smaller ears, should definitely notice fit improvements compared to previous Sphere models.

Fortell AI Hearing Aids use a familiar receiver-in-canal design with a slightly larger body than many other "micro" prescription devices. However, they remain fairly discreet behind the ear. Several colors are currently available with more to come later in 2026.

Audéo EON Sphere offer a significantly smaller size than the previous generation Sphere models. The size is now comparable to most other receiver-in-canal prescription hearing aids on the market.

Fortell AI Hearing Aids has a value score of 3.2/5 based on lab performance and public display price.

Phonak Audéo EON Sphere has a value score of 3.6/5 based on lab performance and public display price.

I found Fortell AI Hearing Aids easy to use and comparable to other receiver-in-canal devices. The app, charging case, and physical buttons all worked well, making day-to-day handling straightforward and giving me easy access to the controls I needed.

Audéo EON Sphere are easy to use and adjust using either the large multi-function button or MyPhonak app. I had no issues making adjustments with either.

Fortell AI Hearing Aids are professionally fit and supported, but access is currently more limited than with major prescription hearing aid brands. In-person care is available in only a handful of major metropolitan areas, though additional clinics are planned. Fortell also offers fully remote care across 30 states, which expands access considerably for those comfortable with telehealth.

Prescription hearing aids like EON Sphere are fit by hearing care providers so you should receive quality care. The MyPhonak app also opens the possibility for remote programming and virtual follow-up appointments.
