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.

Signia Pure Charge&Go MaX achieved a SoundScore of 4.3/5 and a SoundGrade of A in HearAdvisor lab testing. The Prescription Hearing Aid category average SoundScore was 4.19/5.

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.

Pure Charge&Go MaX
4.9EXCELLENT

Pure MaX have an impressive build quality, featuring a top-of-the-line IP68 ingress rating. I also found their portable charging case robust, though on the larger size.

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.

Pure Charge&Go MaX
4.4ABOVE AVERAGE

Pure Max hearing aids have a reported battery life of around 30 hours per charge. While less than Signia's previous Pure C&G device, it is still plenty to get you through the day. Recharging takes 3 to 4 hours which can be done overnight while you sleep.

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.

Pure Charge&Go MaX
5.0EXCELLENT

MaX are Bluetooth compatible with both iOS and Android devices, allowing for 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.

Pure Charge&Go MaX
5.0EXCELLENT

Signia's app stands out with its user-friendly interface and modern, appealing design. It includes practical features like the ability to control the focus of your hearing aids and a mask mode to enhance speech clarity. Additionally, the app offers wellness features, utilizing hearing aid motion sensors for activity tracking.

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.

Pure Charge&Go MaX
5.0EXCELLENT

I found MaX very comfortable due to their shape and earwire design. Your hearing care provider should ensure they are fitted for optimal comfort and hearing benefit before you leave the office.

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.

Pure Charge&Go MaX
4.9EXCELLENT

MaX features a modern, sleek design and is available in a variety of colors, from discreet to bold. This latest generation has a rougher matt finish, which is nice.

Value

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

Signia Pure Charge&Go MaX has a value score of 4.7/5 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.

Pure Charge&Go MaX
4.5EXCELLENT

I did not run into any issues while using MaX hearing aids. They are very easy to use once setup by your hearing care provider. 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.

Pure Charge&Go MaX
5.0EXCELLENT

You should receive quality hearing care and support from your provider. The Signia App should enhance your experience with AI assistance and user-friendly virtual appointments, given your provider offers telehealth services.
