Comparing the Smile Moxi RX 9 with the 7?

All Moxi S-RX hearing aids, regardless of technology level, share the same ERA chip, physical housing, Bluetooth system, charger, and rechargeable RIC design. They all include Noise Reduction, Speech Enhancement, and AutoFocus as standard.

The difference is in how they handle the harder listening situations.

The S-RX 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 directly in front.

In a noisy group situation where someone to your side asks a question, or where two conversations are happening from different directions simultaneously, the S-RX 9 has the hardware and software to handle that. The S-RX 7 does not.

The other meaningful difference is HyperFocus. In very loud environments, this narrows all four microphones into a tight beam in front of you, dramatically improving what you can hear from the person you’re speaking to.

On the S-RX 9, it activates automatically when the hearing aids detect demanding noise. On the S-RX 7, you have to activate it manually.

For people who move between environments regularly and don’t want to manage their hearing aids manually, the S-RX 9’s fully automatic behaviour is the key advantage.

Integra OS: eight environments, all automatic

The Integra OS in the S-RX 9 recognises and adapts to eight distinct listening environments, all without any input from you:

• Conversation in Quiet
• Conversation in Noise
• Conversation in a Small Group
• Conversation in a Crowd
• Conversation in Loud Noise
• Music
• Noise
• Quiet

The final two, Conversation in a Crowd and Conversation in Loud Noise, are exclusive to Level 9.

The S-RX 7 covers up to Conversation in a Small Group.

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.

SoundSonic 360 AI processing

Available exclusively at Level 9, 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 remain followable even when the environment around you isn’t cooperating.

AutoFocus 360 and HyperFocus

AutoFocus 360 uses all four microphones across both hearing aids to identify 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 most effective strategy is sometimes to narrow your focus significantly.

HyperFocus directs all four microphones into a tight beam in front of you, giving you maximum clarity for the person you’re speaking with when the environment is at its most challenging.

On the S-RX 9, both engage automatically.

The hearing aids detect the environment, classify it, and apply the right processing without any input from you.

Universal Bluetooth 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 delivers double the Bluetooth transmission range of previous Unitron models, and hands-free calling works reliably through the hearing aids themselves.

The Remote Plus app gives you additional control when you want it.

Adjust volume and comfort settings, change programmes, view a summary of your listening environment history and daily wear time, and use the Ratings feature to flag moments when the hearing aids are performing well or struggling.

That feedback goes directly to your audiologist for use during remote fine-tuning.

The Log It All feature records which listening environments you’ve spent time in, giving your audiologist a clearer picture of how your hearing aids are performing in your real life, rather than relying solely on a one-off consultation.

There are also two optional app programmes, SpeechSonic and NoiseSonic, that let you adjust how the hearing aids handle speech and background noise in the moment.

If you’d rather not manage your hearing aids at all, that’s fine too. The S-RX 9 is designed to work automatically.

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.

In everyday use, most wearers comfortably get through a full waking day on a single charge. The exact figure will depend on your degree of hearing loss and how much audio streaming you do.

If you travel frequently or are often away from home, the optional ChargerGo has its own built-in battery and charges your hearing aids on the go without needing a mains socket.

This is not included in the standard price (£50 extra for this upgrade).

Accessories

The S-RX 9 is compatible with a range of Unitron accessories.

The TV Connector streams audio directly from your television to your hearing aids.

PartnerMic clips to a conversation partner for clearer one-to-one chat in noisy settings. The Remote Control allows discreet volume and setting adjustments without opening your phone.

Phonak Roger microphones are also supported for group conversations and workplace use.

EasyGuard domes and easy maintenance

The Moxi S-RX 9 is compatible with EasyGuard domes, which feature a sealed membrane that prevents earwax from reaching the receiver.

This reduces the need for cleaning and extends the life of the component, making a real practical difference to your daily maintenance.

The hearing aids are also IP68 rated, meaning they’re dust-resistant and built to withstand splashes, rain, and perspiration without issue.

They won’t survive submersion, but everyday exposure is not a concern.

Who is the Unitron Moxi S-RX 9 suited to?

The S-RX 9 is worth considering if:

• You spend regular time in complex listening environments with multiple speakers and background noise
• You work in a noisy setting, attend meetings frequently, or have an active social life
• You want your hearing aids to manage themselves automatically, without requiring manual adjustments
• Previous hearing aids have worked well at home, but let you down in complicated, real-world situations
• You’ve been avoiding restaurants, pubs, gatherings, or events because the following conversation has become too exhausting

Who might it not suit?

If most of your listening happens at home, in one-to-one conversations, or in quieter everyday settings, the S-RX 9 is more hearing aid than you are likely to need.

The features that justify its price, automatic HyperFocus, AutoFocus 360, and the full eight Integra OS environments, earn their keep in complex, unpredictable noise.

For quieter lives, the S-RX 7 is likely the more sensible choice, and our audiologists will say so honestly.
