4.5EXCELLENT

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.

Build Quality

AI Hearing Aids
4.6EXCELLENT

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.

B3 Powered by Bose
4.8EXCELLENT

Lexie B3 hearing aids offer excellent protection from moisture and debris with an IP68 rating. The portable charge case also appears well built and should easily hold up to daily use.

Battery

AI Hearing Aids
4.6EXCELLENT

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.

B3 Powered by Bose
4.6EXCELLENT

B3 offer an impressive 32 hour battery life per charge, which is more than many products on the market. The portable charging case also offers up to 3 additional charges before needing to be plugged in. As such, we found the overall battery offering excellent.

Bluetooth

AI Hearing Aids
3.0BELOW AVERAGE

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.

B3 Powered by Bose
5.0EXCELLENT

Lexie B3 are Bluetooth compatible with both iOS and Android devices, allowing for wireless app control, audio streaming, and hands-free calling.

App Features

AI Hearing Aids
4.5EXCELLENT

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.

B3 Powered by Bose
4.5EXCELLENT

The Lexie app has a user-friendly interface and modern, appealing design. It includes practical features like volume control and a tone balance. We especially liked that B3 now includes a hearing assessment to better personalize the audio performance to your hearing.

Comfort

AI Hearing Aids
5.0EXCELLENT

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.

B3 Powered by Bose
4.8EXCELLENT

I found B3 very comfortable, and the flexible earwires easily molded to my face which helped provide good retention and speaker placement in my ears.

Design

AI Hearing Aids
4.5EXCELLENT

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.

B3 Powered by Bose
4.8EXCELLENT

B3 are relatively small and have a modern receiver-in-canal design. One potential downside is that they are currently only available in a mat grey color.

Value

AI Hearing Aids

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

Lexie B3 has a value score of 4.5/5 based on lab performance and public display price.

Handling

AI Hearing Aids
4.8EXCELLENT

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.

B3 Powered by Bose
4.8EXCELLENT

I did not run into any issues while using B3 or the Lexie mobile app. First-time users may need some practice to get accustomed to inserting the receiver-in-ear style properly.

Pro Support

AI Hearing Aids
4.0ABOVE AVERAGE

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.

B3 Powered by Bose
3.0ABOVE AVERAGE

B3 are over-the-counter hearing aids and are designed to be fit without a hearing care provider. However, Lexie offers remote care which includes both technical and hearing support from their team of Lexie Experts for the lifetime of your hearing aid.
