Signia Pure Charge&Go MaX Overview
The Signia Pure Charge&Go MaX is a rechargeable receiver-in-canal (RIC) hearing aid built on the all-new Multi-adaptive Xperience (MaX) platform - the world's first multi-dimensional AI hearing aid platform. At Ear to Hear, we are proud to offer this groundbreaking device to our patients across our 12 locations in Florida, Illinois, and Missouri. Available starting August 24, 2026, the Charge&Go MaX represents a fundamental shift in how hearing aids process sound.
What sets the Charge&Go MaX apart from every hearing aid before it is the way it processes sound. Instead of relying on a single processor trying to do everything at once, the MaX platform uses 4 separate Deep Neural Networks (DNNs), each specialized for a specific task. These 4 DNNs work together as what Signia calls Acoustic Intelligence - a system that detects speech, recognizes your own voice, analyzes your environment, and identifies competing noise, all simultaneously and in real time.
The result is a hearing aid that does not just amplify sound - it understands it. Whether you are in a noisy restaurant, a quiet living room, a busy grocery store, or a family gathering with everyone talking at once, the Charge&Go MaX adapts continuously to keep speech clear and background sound comfortable. Signia's philosophy is simple: "Live Noisy." Background sound is not always the enemy. Where there's noise, there's life, and the MaX platform is designed to let you live in it fully.

The MaX Platform: Multi-adaptive Xperience
The Multi-adaptive Xperience (MaX) platform is the foundation of the Signia Pure Charge&Go MaX, and it represents a fundamentally new approach to hearing aid processing. Traditional hearing aids use a single processing chain that tries to handle every aspect of sound at once - detecting speech, suppressing noise, analyzing the environment, and managing your own voice all in the same pipeline. The MaX platform breaks this into 4 specialized Deep Neural Networks, each trained to excel at one specific task, then coordinates their outputs in real time.
This multi-dimensional approach mirrors how the human brain processes sound. Your brain does not have one generic "sound processor" - it has specialized regions for detecting speech, recognizing voices, analyzing environments, and filtering noise. The MaX platform works the same way, which is why Signia calls it Acoustic Intelligence. The result is faster, more accurate, and more natural-sounding than any single-processor system could achieve.
The AI was trained on 40 million real-world sound samples across 11 languages, giving it a deep understanding of how speech and noise interact in diverse environments and cultural contexts. Whether you are speaking English, Spanish, or any of the 11 languages the AI was trained on, the MaX platform recognizes the patterns of human speech and separates it from competing noise with remarkable accuracy.
4 Task-Specific Deep Neural Networks
The heart of the MaX platform is its 4 Deep Neural Networks (DNNs), each specialized for a specific aspect of hearing. Rather than one processor doing everything, these 4 DNNs work in parallel and coordinate their outputs to create a unified, natural listening experience.
1. Speech Detection DNN
Detects and isolates relevant voices in your environment. This DNN is trained to identify human speech patterns and separate the voices you want to hear from the sounds you do not, even when multiple people are talking at once.
2. Own-Voice Detection DNN
Recognizes when you are the one speaking. This is critical because your own voice sounds different from inside your head, and the hearing aid needs to process it differently from external voices. This DNN ensures your voice sounds natural to you, not boomy or distorted.
3. Scene Analysis DNN
Continuously analyzes your ambient environment to understand the listening situation. Is this a quiet room, a noisy restaurant, an outdoor park, or a car? This DNN identifies the scene so the other DNNs can apply the right processing strategy.
4. Noise Processing DNN
Identifies competing noise and separates it from speech. This DNN is trained on millions of noise samples to recognize traffic, restaurant clatter, wind, HVAC systems, and other common noise sources, then reduces them without compromising speech clarity.
4 AI Processing Strategies
Building on the 4 DNNs, the MaX platform deploys 4 AI processing strategies that work together to handle every listening situation you encounter throughout the day. These strategies adapt in real time based on what the DNNs detect in your environment.
1. RealTime Conversation Enhancement (RTCE) AI
Tracks multiple speakers in conversation simultaneously. When you are at a dinner table with several people talking, RTCE keeps track of who is speaking and enhances each voice so you can follow the conversation without missing what someone beside you says.
2. Own Voice Processing AI
Delivers natural voice clarity even during loud conversations. Your own voice is processed separately from external sounds, so it sounds clear and natural to you regardless of how noisy the environment gets around you.
3. Ambient Scene Adaptation AI
Continuously optimizes for your environment. As you move from a quiet office to a noisy street to a car to a restaurant, this strategy adjusts processing parameters in real time so you always hear the right balance of speech and ambient sound.
4. Dynamic Noise Control AI
Softens noise without compromising speech. Instead of cutting out all background sound, this strategy selectively reduces competing noise while preserving the speech you want to hear - keeping the listening experience natural and comfortable.
"Live Noisy" - Where There's Noise, There's Life
Signia's philosophy behind the Charge&Go MaX is captured in a simple tagline: "Live Noisy." The idea is that background sound is not always the enemy. Traditional hearing aids treat all background noise as something to be eliminated, but that approach leaves you with an unnatural, isolated listening experience. Real life is noisy - and that noise is often the sound of life itself.
The laughter of grandchildren, the buzz of a favorite restaurant, the chatter at a family gathering, the sounds of nature on a walk - these are not noises to be silenced. The MaX platform is designed to let you live in these moments fully, keeping speech clear while preserving the ambient sounds that make life feel alive. Instead of cutting you off from the world around you, the Charge&Go MaX helps you engage with it.
This is where the 4 DNNs and 4 AI strategies work together so effectively. The Scene Analysis DNN understands that a restaurant is not the same as a construction site - one is a place where you want to hear the ambient energy, the other is a place where you want maximum noise reduction. The Dynamic Noise Control AI softens harmful or distracting noise while preserving the sounds that add richness to your experience. The result is a hearing aid that does not just help you hear - it helps you live.
Rechargeable Battery and Portable Charger
The Signia Pure Charge&Go MaX is a rechargeable hearing aid designed for people who do not want to think about batteries. The built-in lithium-ion battery charges fully overnight in the included charger, giving you a full day of hearing on a single charge.
