A rechargeable hearing aid that uses four AI neural networks to help you follow group conversations in noise.
The Signia Pure Charge&Go MaX is the first hearing aid built on Signia's new platform, called MaX, short for Multi-adaptive Xperience. Signia describes it as the world's first hearing aid platform to use four dedicated Deep Neural Networks. Where most hearing aids use artificial intelligence for a single job such as reducing noise, MaX runs four separate networks, each trained for a different listening task, that share information with each other in real time.
A Deep Neural Network (DNN) is a form of AI modeled loosely on the way the brain processes information. Running four of them at once gives the hearing aid a more complete picture of what is happening around you before it decides how to handle the sound.
The goal is not simply to make noisy rooms quieter. It is to keep you connected to the people you want to hear while preserving your awareness of everything else, which is especially hard during moving group conversations where several people talk at once. The Pure C&G MaX is a rechargeable receiver-in-canal (RIC) hearing aid, the most common style, where a small unit sits behind your ear and a thin wire carries sound to a speaker in your ear canal.
Signia calls this coordinated approach Acoustic Intelligence. The four networks each handle a different part of the listening picture and constantly share what they find:
Running four neural networks continuously takes considerable processing power. Compared with Signia IX, Signia reports the new MaX chip delivers 54 times more processing power, 50% greater energy efficiency, and twice the memory, which is what lets the system stay active all day rather than switching on only for a special listening mode.
MaX is built specifically for difficult group conversations, coordinating processing between both hearing aids as the conversation moves around the table. In Signia-sponsored research, 97% of participants performed better with MaX in noisy group conversations than with key competitors, and Signia reports MaX ranked first for signal-to-noise performance in group conversation in noise. These are manufacturer-cited results, so they are best read as promising early evidence alongside independent testing and your own experience.

The Pure C&G MaX uses what Signia calls OneConnect Technology, which brings several wireless and assistive-listening options together in a single hearing aid:
The hearing aid supports both iPhone and Android, though the exact features available depend on your phone model and operating system, so compatibility is worth confirming for your specific device.
One important note on Auracast: the hardware is ready, but Signia has said full Auracast functionality will be switched on through a Signia One app firmware update by March 2027. Until that update arrives, Auracast is not yet active on the device.
The Pure Charge&Go MaX is a rechargeable RIC hearing aid available in eight color options. It ships with a pocket-size portable charger that holds up to four full additional charges, so you can top up away from an outlet.
Signia reports that a full charge takes about four hours, and a 30-minute quick charge provides up to six hours of use, enough to cover an unexpectedly long day or an evening out.
The Pure Charge&Go MaX is worth considering if your hardest listening moments involve restaurants, social events, meetings, family gatherings, or other places where several people talk at once and noise comes from every direction. Its broad connectivity also makes it appealing if you want a hearing aid that can work across current and emerging wireless audio systems.
The most advanced hearing aid is not automatically the best one for you. Your hearing test results, speech-in-noise ability, ear anatomy, listening needs, and how you respond to amplification all matter when choosing a device, and the figures above come from manufacturer research and laboratory conditions rather than guaranteed real-world outcomes.
What stands out about MaX is not simply that it uses more AI, but how the four systems are designed to work together, since real-world listening is messy and the wearer is part of the conversation too. Even so, specifications only matter if they translate into better hearing for you. That is why professional fitting matters as much as the technology itself. A provider who follows Best Practices, including Real Ear Measurement to verify that the sound reaching your eardrum matches your prescription, is what determines whether MaX delivers in the situations that matter most to you.
