Hearing Aid Comparison
Two flagship hearing aids launched in August 2026 within a fortnight of each other, and both built their announcements around artificial intelligence. Oticon Reveal arrived on August 11 running two AI systems with deliberately opposing objectives. Signia MaX arrived on August 24 running four deep neural networks under a single coordinating system.
They are the two newest prescription hearing aids you can be fitted with today, and they are more similar than the marketing suggests: both are rechargeable receiver-in-canal devices, both launched in one style, both arrived with performance figures generated entirely in their own manufacturers' laboratories, and neither has been measured by anyone independent.
We fit both at our San Mateo and San Carlos offices, we are not tied to either manufacturer, and we can set them up side by side in a single appointment. Here is where each one is genuinely ahead.
At a glance
- Reveal runs two AI systems with opposing objectives; MaX runs four purpose-trained neural networks under one coordinator. Both are real architectural positions, neither is independently validated.
- Oticon Reveal's Auracast works today. Signia MaX's is hardware-ready but not enabled until a firmware update due by March 2027.
- Both launched in a single rechargeable receiver-in-canal style. Reveal adds a CROS transmitter; MaX has no CROS option on the platform.
- Every performance number from both companies comes from their own unpublished internal documents. No independent laboratory has measured either device.
- The best measured speech-in-noise performance available today belongs to neither — it belongs to older, well-tested platforms.
Two different bets on what AI should do
Oticon's argument with Reveal is that pulling speech out of noise costs you something worth keeping. Suppress a room aggressively enough to isolate a voice and you lose the footsteps behind you, the acoustics that tell you a space is large, the door that just opened — cues your brain uses to stay oriented. So Reveal runs Speech AI to lift voices and Context AI to preserve the ambient detail the first one would strip, deliberately pulling in opposite directions. Signia's argument with MaX is different. It is that a single network, however good, is making too many decisions at once. So MaX splits the work across four purpose-trained networks — speech detection, own-voice detection, scene analysis and noise processing — and coordinates them, on the theory that a system which separately understands what kind of room you are in, whether the voice it found is yours, and whether you are in a conversation at all will behave more sensibly than one that only knows how to reduce noise. Both are real architectural positions rather than marketing dressing. Neither has independent evidence behind it. If you want the wider context, we wrote about what Dual AI actually means in hearing aids.
Connectivity: Reveal is ahead today, MaX catches up in 2027
This is the clearest practical difference, and it runs the opposite way to how it is being reported. Both devices support Bluetooth LE Audio, both include a telecoil, and both advertise Auracast broadcast audio. But Oticon Reveal's Auracast is live and working now, while Signia states that full Auracast functionality on MaX arrives in a firmware update by March 2027. Until then MaX is Auracast-ready rather than Auracast-capable. Where MaX pulls ahead is the packaging. Signia's OneConnect puts Bluetooth Classic, LE Audio, telecoil and Auracast hardware into the standard device, so there is no variant to choose and no trade-off between loop access and the mainstream model. Reveal also includes a telecoil, is Made for iPhone certified and supports Google Fast Pair on Android. For most people the day-to-day experience will be similar; if broadcast audio in public venues is specifically why you are buying, Reveal can do it this year and MaX cannot.
Styles and who gets left out
Both platforms launched with exactly one model, and both leave the same patients behind. Reveal ships as a rechargeable miniRITE R. MaX ships as the rechargeable Pure Charge&Go MaX. Neither offers a behind-the-ear device, a custom in-the-ear device, or a disposable-battery option. Reveal has one meaningful advantage here: a CROS transmitter launched alongside it for single-sided deafness, which MaX does not have on the platform. If you need any of the styles neither offers, the answer is not to compromise on fit for the sake of a launch — it is to look at the outgoing platform from either company. Signia IX covers custom, instant-fit, slim, powerful behind-the-ear and CROS options and has independent laboratory scores; Oticon Intent offers a behind-the-ear model. Both are current and supported.
The claims, compared
Neither manufacturer is being dishonest, and both are doing the same thing. Oticon reports a 60% stronger brain response than Oticon Intent, up to 25 dB more available gain than three top competitors, up to 91% predicted speech access, and 94% user preference over Intent. Every one of those traces to an Oticon-authored research brief or technical paper, and the citation behind the 60% figure has no published title, journal or sample size. Signia reports that 97% of wearers perform better in noisy group conversations than with key competitors and that MaX ranks first in signal-to-noise ratio in group conversation, both citing unpublished Signia white papers with the competitors unnamed; its 54-times-processing-power figure is footnoted simply "Compared to Signia IX," and its 75%-more-data-points claim carries no footnote at all. Read side by side, the pattern is the same: the numbers are internal, the comparators are often the manufacturer's own previous product, and the methodology is not available to check. Treat both sets as engineering statements rather than promises about your hearing.
Neither has been independently measured
HearAdvisor, the laboratory whose standardised measurements come closest to a neutral referee in this industry, has published results for neither Reveal nor MaX. That is not a criticism of either device; it is what the evidence base looks like weeks after launch, and it usually takes several months to change. It does mean that if what you want is the best measured speech-in-noise performance available today, the honest answer is that it belongs to neither of these — Phonak's Audéo Infinio Ultra Sphere holds the highest score any laboratory has recorded, and Starkey Omega AI ranks second of thirty-six tested. Both are older platforms with published data. That is a real trade-off to weigh, not a reason to dismiss the new devices.
Which we would suggest, and when
If Auracast in public venues is a genuine part of your week, Reveal today. If you have single-sided deafness and want a current platform, Reveal, because of the CROS transmitter. If group conversation in busy, shifting rooms is the specific thing that defeats you, MaX is the platform aimed hardest at that problem — and it is also the claim with the least independent support, so demonstrate it rather than trust the figure. If you have worn one of these brands successfully for years, that history is worth more than either specification sheet; brands differ in sound character, and a patient who has adapted well to Oticon's fuller, more open sound often does not enjoy a more actively processed one, and the reverse is just as true. And if you need a style neither offers, neither is the answer.
What settles it is a demonstration and a verified fitting
We can set Reveal and MaX up in one appointment and let you switch between them in a noisy environment rather than a quiet booth, which resolves the question far more reliably than any comparison page including this one. Whichever you choose, we program it to your prescription and confirm it with real-ear measurement, because manufacturer first-fit settings routinely land below prescriptive targets — often by enough to erase whatever advantage you paid for. A verified device from either company will outperform an unverified device from the other. Call 650-342-9449 or request an appointment.
Frequently asked questions
A few questions worth asking
Which is better, Signia MaX or Oticon Reveal?
Nobody can answer that from published evidence, because no independent laboratory has measured either one. The differences that can be stated as fact are practical: Reveal's Auracast works now and it has a CROS transmitter; MaX bundles telecoil and Auracast hardware into the standard device with no variant to choose. Sound character differs between the two brands, and that is best settled by listening to both.
Do both work with iPhone and Android?
Yes. Both stream directly from recent iPhones and from Android phones that support the relevant Bluetooth profiles, and both handle hands-free calling on compatible devices. Reveal is Made for iPhone certified and supports Google Fast Pair; MaX uses Signia's OneConnect, which includes Bluetooth Classic alongside LE Audio for broader phone compatibility.
Which one has better battery life?
Signia publishes charging figures for MaX — a pocket charger holding four full charges, four hours to full, and about six hours of use from a thirty-minute top-up — but has not published a total runtime per charge. Oticon publishes runtime figures for Reveal. Because the two companies measure and report differently, a direct comparison is not currently possible without putting them on the bench ourselves.
Should I wait for independent test results?
If you are managing well with your current hearing aids, waiting a few months costs you nothing and independent measurements will exist by then. If you are struggling now, the benefit of being fitted and verified properly today almost certainly outweighs waiting — and if measured performance is your priority, there are already-tested platforms that are excellent and often less expensive.
Can I try both at your office?
Yes. We fit both brands and can demonstrate them in the same appointment, ideally in a noisy environment rather than a quiet booth. It takes about forty-five minutes and there is no charge. Call 650-342-9449 or request an appointment online.
