Signia Pure Charge&Go MaX — Freehold, NJ
The World's First Four-DNN Hearing Aid Platform
Live Noisy

Most hearing aids use artificial intelligence for one job: reducing noise. The argument behind that approach is reasonable — background noise is the primary reason speech becomes difficult to understand in challenging environments, and reducing it should help. The limitation of that approach is equally clear: applying a single neural network to a problem with multiple distinct components means every component gets a compromised answer
.
On August 24, 2026, Signia introduced a different architecture. The Signia Pure Charge&Go MaX — the first hearing aid built on the Multi-adaptive Xperience platform — runs four dedicated deep neural networks simultaneously, each trained exclusively for a different component of the listening challenge. Not one AI system trying to handle four different problems. Four AI systems, each built for one problem, sharing what they learn with each other in real time.
At Haynie Audiology, every MaX fitting begins with a comprehensive hearing evaluation and is verified with real ear measurement — ensuring the platform's processing is built on precisely the right amplification foundation for your specific hearing and anatomy.
Acoustic Intelligence — The Four DNNs and What Each One Does
Signia names its four-network system Acoustic Intelligence. Each DNN has a clearly defined and separate function:
RealTime Conversation Enhancement — Tracks multiple moving speakers simultaneously in group conversations. When people are talking, turning, shifting position, or switching who is speaking — a restaurant, a family dinner, a meeting — RealTime Conversation Enhancement follows each voice dynamically rather than committing to a fixed directional focus or waiting for the conversation to settle. This is not a new feature for Signia — it was introduced on the IX platform — but on MaX it runs on a dedicated network rather than sharing resources with other processing tasks, and processes 75% more data points per second than on IX.
Own Voice Processing (OVP) — Processes the wearer's own voice on a completely separate audio stream from all external sounds. This addresses the most common reason first-time hearing aid users abandon their devices — their own voice sounds wrong. On MaX, OVP introduces a meaningful improvement over the IX version: the individual training step that previously required the patient to read sentences aloud at the fitting appointment so the hearing aids could learn their voice is eliminated. MaX recognizes the acoustic characteristics of self-generated speech automatically, without calibration. The own-voice experience is natural from the first day of wear.
Ambient Scene Adaptation — Reads and characterizes the acoustic environment the wearer is in. The size of the space, its reverberance, the noise floor, where sound sources are positioned, how the room responds to sound. This information is passed in real time to the other three networks so their processing decisions are informed by the actual acoustic context rather than a generic classification.
Dynamic Noise Control — Manages the remaining background noise after the other three networks have done their work. Because it receives real-time information from Ambient Scene Adaptation about the specific noise characteristics of the environment, and from RealTime Conversation Enhancement about which sounds are speech and where they are coming from, Dynamic Noise Control makes more targeted decisions than a conventional noise reduction system working without that context.
The four networks share information continuously. Each improves the accuracy of the others. The result Signia describes is sound adjustment that feels smoother, more natural, and less fatiguing — because the processing decisions are coordinated across four specialized systems rather than approximated by one general one.
The MaX Chip — What Makes This Possible
Running four dedicated DNNs simultaneously, continuously, and in real time requires processing capacity that the previous Signia IX chip could not provide. The new MaX chip delivers:
-
54 times more processing power than the IX chip
-
50% greater energy efficiency than IX — meaning the additional processing does not proportionally increase battery drain
-
Twice the memory of IX — enabling the larger models each network requires
The efficiency improvement is what makes the battery life figures below possible despite the additional computational load. The MaX chip was purpose-built for Acoustic Intelligence — not a consumer processor adapted for hearing aid use.
OneConnect — Universal Connectivity in a Single Device
Connectivity has historically required hearing aid buyers to make a choice: Bluetooth Classic for broad device compatibility, or Bluetooth LE Audio for better audio quality and lower power consumption. Adding a telecoil for hearing loop access required a specific hardware variant. Auracast readiness was a separate consideration.
The MaX introduces OneConnect Technology — the first Signia device to include all four in a single, standard hardware configuration:
Bluetooth Classic — Direct, long-range streaming from Bluetooth-enabled smartphones, televisions, and computers. Works with virtually any Bluetooth device regardless of operating system or version.
Bluetooth LE Audio — Lower power consumption, higher audio quality, and the foundation for the next generation of hearing aid connectivity. For compatible devices, LE Audio provides the cleanest streaming experience available.
Telecoil — Built into every MaX device, providing compatibility with hearing loop systems installed in houses of worship, theaters, airports, and other public venues without requiring a specific hardware variant.
Auracast — The hardware is present and ready in every MaX device. One important and honest note: full Auracast functionality is not enabled at launch. Signia has confirmed that full Auracast will be activated through a Signia One app firmware update expected by March 2027. Patients who need Auracast working immediately should discuss this timeline at the fitting consultation.
Own Voice Processing — No Training Step Required
The improvement to OVP on MaX deserves its own specific mention because it changes the fitting experience in a way that matters.
On the Signia IX platform, OVP required an individual calibration step at the fitting appointment — the patient read a series of sentences aloud so the hearing aids could learn the specific acoustic characteristics of their own voice. This added time to the fitting and occasionally required repeating if the initial capture was not successful.
On MaX, this step is removed entirely. The Own Voice DNN identifies self-generated speech by its acoustic characteristics without requiring individual training — making the fitting simpler and delivering natural own-voice comfort from the first wear without the calibration session. For patients who have previously found this step inconvenient, or for patients who have previously found own-voice comfort to be a problem with hearing aids, this improvement is clinically meaningful.
Battery Life
The MaX delivers the following battery performance from a full charge:
-
Up to 30 hours without streaming
-
Up to 28 hours with five hours of Bluetooth LE Audio streaming per day
-
Up to 22 hours with five hours of Bluetooth Classic streaming per day
Quick charge: approximately six hours of use from 30 minutes on the charger. Full charge time: approximately four hours.
The pocket-sized charging case holds up to four additional full charges — providing meaningful all-day and travel backup without requiring access to a power outlet.
Technology Levels — MaX 7, MaX 5, and MaX 3
The Pure Charge&Go MaX is available in three technology levels. All three share the same Pure rechargeable RIC design, the same four Acoustic Intelligence DNNs, the same battery specifications, the same OneConnect hardware, and the same eight color options.
The differences are in processing depth and fine-tuning capability:
MaX 7 — The premium tier at 48 processing channels. Maximum feature ratings across all four Acoustic Intelligence systems. The technology level used in Signia's published group-conversation research. For patients who regularly encounter the most demanding multi-speaker noisy environments.
MaX 5 — The advanced tier at 36 channels. Strong Acoustic Intelligence performance for patients with varied routines and regular social activity in moderately demanding environments.
MaX 3 — The standard tier at 32 channels. Core Acoustic Intelligence processing for patients with more familiar and less complex listening situations. The most accessible price point in the MaX range.
An important honest note: the performance figures cited in Signia's published research — including the 29 of 30 participants achieving best understanding with MaX in group conversation — reflect MaX 7 testing conditions. Those results should not be directly applied to MaX 5 or MaX 3 without qualification.
What the Evidence Shows — And What It Does Not Yet Show
The MaX platform launched on August 24, 2026 — approximately one month before this page was written. Every performance figure available at this time comes from Signia's own internal research and white papers. No independent laboratory — including HearAdvisor, which has tested and published strong results for the Signia IX platform — has published an independent evaluation of the MaX at the time of writing.
This does not mean the claims are wrong. Signia's research group has a strong track record, and the IX platform's independently verified results support confidence in their engineering approach. It does mean that patients who specifically value independent third-party verification before committing to a new platform should understand that those results are pending, and that they are expected in the coming months.
The Signia IX platform has independent verification and a strong track record. The MaX platform has a more powerful chip, four dedicated DNNs, and compelling internal research. The right choice between them depends on how much weight a patient places on novelty versus verified track record — a conversation Dr. Haynie will have with every patient considering either platform.
Is the Signia MaX Right for You?
The MaX is most suited for adults with mild to severe hearing loss whose primary challenge is following group conversation in noisy, multi-speaker environments — restaurants, family gatherings, meetings, social events where multiple people are speaking simultaneously. Patients who want Signia's most current platform and the most advanced AI architecture currently available from the brand. Patients who want universal connectivity — Bluetooth Classic, LE Audio, and telecoil — in a single device without choosing between hardware variants. Patients who have previously abandoned hearing aids because their own voice sounded wrong and want the simplified, no-training-step OVP experience.
The MaX is not the right choice for patients who need a form factor other than a rechargeable RIC — custom in-the-ear, slim, earbud, or power BTE options are not yet available on the MaX platform and remain on the IX platform. Patients who need Auracast working immediately rather than in March 2027. Patients who strongly prefer independently verified performance data before committing — for those patients, the Signia Pure Charge&Go IX has strong independent results and a well-established track record.
