Signia AX hearing aids, encompassing the Pure AX and Styletto AX models, have gained a reputation for their advanced technology and unique features. These models are part of the Augmented Xperience (AX) platform, launched by Signia, a prominent brand under the WS Audiology umbrella. The AX platform has been specifically designed to address the common complaints of hearing aid users, offering improvements in speech recognition, noise reduction, and sound quality.

The Augmented Xperience Platform

The Augmented Xperience (AX) platform is the core of the Signia AX hearing aids and is responsible for their revolutionary features. Built on a dual-processor architecture, the platform separates speech and background noise processing, allowing users to focus on conversations while minimizing distracting noise. This split-processing paradigm provides an immersive soundscape with outstanding speech clarity, enhancing real-world listening experiences.

A Closer Look

The Pure AX model, the flagship product of the AX platform, was launched in May 2021 and has been celebrated for its advancements over its predecessor, the Pure X. With major improvements in binaural audio transfer rates, reduced latency, and increased battery runtime, the Pure AX offers an impressive array of features.

Key Features of Pure AX

The Pure AX model provides dual processors for separate speech and environmental noise processing, a feature unique to the AX platform. It also includes the latest version of the Own Voice Processing (OVP™ 2.0) and Auto EchoShield which further enhance the auditory experience.

One of the key advancements is its compatibility with both Android and iOS devices, a first for Signia. This feature allows users to stream audio directly from their smartphones to their hearing aids. However, the microphones on the Pure AX do not act as an input while on a call, and users will need to speak into the phone. The StreamLine Mic, a separately-purchased accessory, can be used to enable hands-free phone calls with Pure AX Signia.

The Pure AX also boasts of a 110% increase in the binaural audio transfer rate and a 60% reduction in binaural latency, compared to its predecessor. Moreover, it offers a 22% increase in rechargeable battery runtime and an increased input dynamic range, improving the quality of loud sounds.

Smartphone Compatibility

One major feature of the Pure AX model is its compatibility with both Apple and Android devices. The Android compatibility, a first for Signia, marks a significant step for the company as approximately 50% of the U.S. smartphone market is Android, according to Statista. The Android streaming is achieved via the Audio Streaming for Hearing Aids (ASHA) protocol.

Augmented Focus

One of the key features of the Pure AX model is the Augmented Focus™ technology. This feature uses two separate processors to process sound that you want to hear, such as conversation, separately from surrounding noise. This technology is aimed at improving your speech understanding in environments with competing noise such as restaurants.


The Pure AX model continues Signia's tradition of offering rechargeable hearing aids. The Pure Charge&Go AX has built-in lithium-ion rechargeable batteries designed to provide up to 36 hours of wearing time if utilizing the larger model (T AX) with the telephone coil (T-coil) or up to 24 hours for the smaller no T-coil version (AX).

Own Voice Processing 2.0 (OVP 2.0)

Another unique feature of the Pure AX model is the Own Voice Processing 2.0 (OVP 2.0). This feature allows for separate processing for your own voice, improving the comfort and quality of your own voice through the hearing aids. This feature is unique to Signia and can significantly improve overall satisfaction with the hearing aids.

Signia Styletto AX

The Styletto AX model, released in September 2022, offers the same advanced features of the AX platform as the Pure AX model, but in a slim and stylish Receiver-In-Canal (RIC) design. This model is suitable for a wide range of hearing losses from mild to severe and is a good choice for users who prefer a lightweight and stylish design.

Key Features of Styletto AX

The Styletto AX model possesses all the key features of the AX platform, such as Augmented Focus™ and Own Voice Processing 2.0 (OVPTM). It also includes the Signia Assistant feature, which allows users to personalize their hearing aids in real-world settings via the Signia app. Furthermore, it includes a fitness tracking feature called "My WellBeing" within the Signia smartphone app, providing information on steps taken, overall activity level, hearing aid wearing time, and estimated social interaction.

Wireless Connectivity

Both the Pure AX and Styletto AX models use Bluetooth® for direct connectivity with iOS and select Android devices. This allows for seamless audio streaming to your hearing aids, including phone calls and other media. For non-compatible devices, the StreamLine Mic accessory offers hands-free and stereo audio streaming from most Bluetooth devices.

Battery Charging

Both Pure AX and Styletto AX models utilize lithium-ion rechargeable batteries. The Styletto model offers a portable on-the-go charging case allowing for up to 4 full charges on the go. This is greater than what most competitors offer. A Dry&Clean charger is also available, which charges the hearing aid batteries while also helping to dry out the hearing aids and clean them using a UVC light.

The Signia App

The Signia App, available for both Android and Apple smartphones, offers a range of functionalities beyond simple controls. It includes the "My WellBeing" health feature that tracks your overall activity level, hearing aid wearing time, and estimated social interaction. The Signia Assistant feature allows you to adjust your hearing aids in real-time in your distinct listening environments, improving the sound quality of the hearing aids and allowing for personalization of the programming.

Longevity and Maintenance

Signia AX hearing aids, like many of Signia's and other manufacturers' products, have an IP 68 rating. This means the product is resistant to both moisture and dust and can even be submerged in water up to a maximum depth of 1.5 meters for up to 30 minutes. This can help prolong the life of the hearing aid.
