Unitron Moxi S-RX 9 Hearing Aids Overview
If you frequently find yourself in challenging listening situations, from busy restaurants and conference rooms to large family gatherings and noisy workplaces, and you want your hearing aids to handle them without you having to think about it, the Unitron Moxi S-RX 9 hearing aids are the model to consider.
It sits at the top of the Unitron Smile range, and the meaningful difference over the lower levels isn’t just processing power in the abstract. It’s the combination of AutoFocus 360 and fully automatic HyperFocus: features that work together in real time, without requiring you to press a button or open an app, to give you the clearest possible speech in the most demanding listening environments.

What makes the 9 different from the 7?
This is the question worth answering honestly, because the technology level choice is where most people get lost. All Moxi S-RX hearing aids, regardless of level, use the same ERA chip, the same physical housing, the same Bluetooth system, and the same charger.
They’re all rechargeable RIC (Receiver-in-Canal) aids, meaning the main unit sits behind the ear with a thin wire to a small speaker in the ear canal. They all include Noise Reduction, Speech Enhancement, and AutoFocus. The difference is in how the aids handle the hard stuff.
The Level 9 is the only tier with AutoFocus 360, which means it can identify and enhance speech coming from any direction around you, not just from in front. In a noisy group situation where someone behind you asks a question, or where two conversations are happening simultaneously from different directions, the S-RX 9 has the hardware and software to handle that. The S-RX 7 does not.
The other significant difference is HyperFocus. This is a feature that narrows the microphones’ focus to a tight beam in front of you in very loud noise, dramatically improving what you can hear. On the S-RX 9, it activates automatically when the aids detect you’re in a very loud environment with speech. On the S-RX 7, you have to activate it manually.
For people who are out in the world regularly, move between environments frequently, and don’t want to manage their hearing aids manually, the S-RX 9’s fully automatic behaviour is the key advantage.
Integra OS: all eight environments, fully automatic
The Integra OS in the S-RX 9 recognises and adapts to eight distinct listening environments automatically:
- Conversation in Quiet
- Conversation in Noise
- Conversation in a Small Group
- Conversation in a Crowd
- Conversation in Loud Noise
- Music
- Noise
- Quiet
The last two environments on the list, Conversation in a Crowd and Conversation in Loud Noise, are exclusive to Level 9. The S-RX 7 includes Conversation in a Small Group but not in a Crowd or in Loud Noise. The S-RX 5 starts from Conversation in Noise and doesn’t go further.
In practice, this means the S-RX 9 adapts intelligently to the most demanding situations you can put it in. You don’t manage it. It manages itself.
SoundSonic360
Only available in the top two technology levels, the SoundSonic360 is the AI processing system at the heart of the Moxi S-RX 9. Powered by a deep neural network (DNN) chip, it identifies speech within background noise and keeps it clear in real time, so conversations stay followable even when the environment around you isn’t cooperating.
AutoFocus 360 and HyperFocus: the technical detail
AutoFocus 360 uses all four microphones across both hearing aids to work out where speech is coming from and enhance it dynamically from that direction. Dynamic Noise Reduction works alongside it to reduce competing background sounds in real time.
HyperFocus takes a different approach. In very loud noise, the best strategy is sometimes to narrow your focus significantly rather than trying to hear from all directions. HyperFocus directs all four microphones into a tight beam in front of you, giving you maximum clarity for the person you’re speaking to when the environment is at its most challenging.
On the S-RX 9, both of these engage automatically. The hearing aids detect the environment, classify it, and apply the right processing without any input from you.
Connectivity and the Remote Plus app
The Moxi S-RX 9 connects via Bluetooth to both iPhone and Android smartphones, as well as tablets and other Bluetooth-enabled devices. You can pair up to eight devices and have two connected simultaneously. The ERA chip provides double the Bluetooth transmission range of previous Unitron models, and hands-free calling works reliably through the aids themselves.
The Remote Plus app gives you additional control when you want it. You can adjust volume and comfort settings, change programmes, see a summary of your listening environment history and daily wear time, and use the Ratings feature to flag moments when the aids are performing well or struggling. That feedback goes directly to your audiologist, who can use it to fine-tune your settings at your next appointment.
The Log It All feature in the background records which environments you’ve been spending time in, which helps your audiologist understand how your aids are performing in your real life, rather than guessing from a clinic appointment.
For people who’d rather not manage their aids at all, that’s fine too. The S-RX 9 is designed to work automatically. The app is there if you want it.
There are two new DNN-powered Optional App Programmes, SpeechSonic and NoiseSonic, that let you adjust how the aids handle speech and background noise in the moment.
Battery life and charging
A full charge from the included Charger RIC S takes around three hours and delivers up to 24 hours of use. The precise figure depends on the degree of your hearing loss and how much streaming you do, but in normal use, most wearers will comfortably get through a full waking day on a single charge.
If you travel or are often away from home, the optional ChargerGo has its own built-in battery and charges the aids on the go without needing a mains connection. It’s not included in the standard price but is worth considering if your lifestyle demands it.
Easy maintenance
EasyGuard domes are compatible with the Moxi S-RX 9. These dome tips have a sealed membrane that prevents earwax from reaching the receiver, which reduces the need for cleaning and extends the life of the component. It’s a practical feature that makes a real difference to daily maintenance.
The aids are also IP68 rated, meaning they’re resistant to dust and can withstand immersion in water up to a certain depth. They won’t survive swimming, but rain, sweat, and the occasional accidental splash aren’t a concern.
Who is the Unitron Moxi S-RX 9 suited to?
The S-RX 9 is the right choice if:
- You spend significant time in complex listening environments with multiple speakers and background noise
- You work in a noisy environment, attend regular meetings, or have an active social life
- You want your hearing aids to manage themselves automatically without requiring manual adjustments
- You’ve been frustrated by previous hearing aids performing poorly in exactly the situations where you most need them
- You’re an NHS upgrader who knows their current aids work adequately at home but let them down in busy real-world environments
- If your hearing needs are primarily in quieter, everyday settings, you may not use the full capability of the S-RX 9 regularly.
A word on independence: Unitron is part of the Sonova group, the same parent company as Phonak. Our HCPC-registered audiologists are not affiliated with any manufacturer, so if a different brand or model would serve you better, that’s what they’ll tell you.
Who might it not suit?
If you’re mostly at home, watching TV, chatting with one or two people, or in smaller social situations without significant background noise, the S-RX 9 is more hearing aid than you need.
That’s not a criticism of the technology; it’s an honest acknowledgement that the features which justify its price, automatic HyperFocus, AutoFocus 360, the full eight Integra OS environments, only earn their keep in complex, unpredictable noise. For quieter lives, the S-RX 7 is the more sensible choice, and one of our qualified audiologists will tell you so without any hesitation.
