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.

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.

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.

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.

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.

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.

Adjustment BandsAdjustment BandsThese are frequency-divided sections that can be adjusted in a hearing aid in order to amplify sounds. Although there are rarely more than 10 frequencies measured in a hearing assessment, having more bands that can be adjusted may allow for improved speech understanding and user comfort.

AI Noise RemovalAI Noise RemovalArtificial Intelligence is utilized to remove or modify background noise from the sound signal to help isolate speech for better speech understanding.
Spatial AISpatial AIThe separation network attenuates competing speech as well as non-speech noise -- the case conventional digital noise reduction cannot address, because competing speech occupies the same frequency bands as the target talker and shifts constantly.Also covers Machine Learning, Unique Amplification Strategy

No
Direction SelectionDirection SelectionAllows the user to select one or more directions to focus their hearing aids on. For example, some hearing aids allow the listener to focus on sounds coming from in front or back, or from the right or left.
Front VoicesFront VoicesThe wearer selects front-only focus by hand, from the companion app or by holding the mode button on the right hearing aid. Fortell does not switch modes automatically: the difference between its modes is large enough that being in the wrong one costs more than automatic switching saves.FrontAlso covers Spatial Noise Cancellation
No
DirectionalityDirectionalityDepending on the types and number of microphones a hearing aid has, the hearing aid may be able to boost sounds from specific directions (by reducing sounds from other directions). This can be helpful to focus on a speaker directly in front of the hearing aid user, as well as to give the user information about where different sounds are coming from.
Adaptive
Adaptive Directionality™Adaptive Directionality™Adaptive Directionality slowly transitions between omnidirectional and directional settings based on an analysis of the acoustic environment.Binaural Directionality™ IIIBinaural Directionality™ IIIBinaural Directionality III provides the ultimate balance for supporting natural hearing: a signal-to-noise ratio improvement similar to bilateral directional microphones and a significant benefit in ease of listening compared to other directional microphone strategies.
Environmental AdaptationEnvironmental AdaptationThe hearing aid can detect different acoustical environments, like speech in noise, and adjust the sound of the hearing aid accordingly to drive comfort or speech understanding, etc.
No
Environmental OptimizerEnvironmental OptimizerProvide automatic adjustment of hearing instrument settings.
Feedback SuppressionFeedback SuppressionIf any sound amplified by the hearing aid escapes the ear canal, it may reach the hearing aid’s own microphone and cause a harsh whistling noise. Some hearing aids are able to recognize when this feedback occurs and reduce or eliminate it.
Yes
DFS Ultra IIIDFS Ultra IIIReduces feedback while preserving amplification without compromising sound quality.
Frequency LoweringFrequency LoweringUnderstanding certain speech sounds is dependent on the high frequency parts of these sounds. For individuals with high frequency hearing loss, this feature can take high frequency speech information and move it to lower frequencies where it will be audible.
No
Sound ShaperSound ShaperSound Shaper is the only frequency compression technology that moves high-frequency sounds down in the spectrum while maintaining a proportional relationship between input and output frequencies. So Sound Shaper improves the audibility of speech cues that would otherwise be lost, while maintaining the best sound quality possible.

Spatial AISpatial AISource-separating neural network that models both what a sound is and where it comes from. It reads sub-millisecond differences in timing, spectral content and amplitude across the microphones to split the incoming scene into sound that should be amplified and sound that should not, then amplifies only the former. Unlike a beamformer, which passes whatever falls inside its spatial filter, direction here is one input to a learned separation model that also reasons about whether a sound is a talker the wearer is attending to.Also covers AI Noise Removal, Machine Learning
