Resound Sensia 9 Hearing Aids Overview
Launched in October 2026, the Resound Sensia 9 hearing aids are the top technology level in the range. They’re also the only Sensia level that delivers the whole idea behind the range: a hearing aid that notices when a conversation has become hard work and deals with it on its own, without you reaching for an app or a button.
Resound calls this Intelligent All-Around. At Sensia 9, in the rechargeable microRIE style, it runs automatically inside your everyday listening programme.
It’s worth being clear about what’s new. Sensia 9 runs on the same chip and AI engine as the Resound Vivia 9. The difference is in the decision-making. Vivia’s strongest noise processing sat in a separate programme you had to choose. Sensia 9 decides for itself when to use it.
Hearing Aid UK supplies and professionally fits the Resound Sensia 9 throughout the UK. Appointments are available at 93+ clinics or through free home visits.
Key features of the Sensia 9
- Intelligent All-Around: Automatic sensing, directional focus and AI noise reduction working as one system (microRIE only).
- Intelligent Focus: Four-mic beamforming and DNN noise reduction combined, for the toughest background noise. It is also available on demand in a Hearing in Noise programme.
- Intelligent Noise Tracker: Three strength settings, and you can boost it further with a swipe in the app.
- 360 All-Around directionality: Keeps you aware of your surroundings when you’re not in a difficult conversation.
- Direct streaming: Bluetooth LE Audio and Auracast, plus Made for iPhone and Android (ASHA) streaming.
- TapControl: On the microRIE, you can answer or end calls by tapping your ear, with compatible phones.
- Water and dust resistance: IP68-rated with nanocoating on every part.
- Tinnitus support: A built-in Tinnitus Sound Generator that your audiologist can set up.
- Colours available: Red, navy blue, sparkling silver, sand, gold, bronze, warm grey, graphite, espresso and deep black.
How Intelligent All-Around works
Three systems work together, and at Sensia 9, all three run without any input from you:
- AcoustIQ (sensing the room): Resound’s classifier reads the environment continuously. It doesn’t just label the situation; it switches on the features that will actually help. Resound reports 91% classification accuracy in its own testing.
- Four-microphone focus: Both hearing aids combine their microphones into one forward-facing beam, on the basis that you usually look at the person you want to hear. Some awareness of sound around you is kept, rather than cut out entirely.
- AI noise reduction: The DNN is trained to separate speech from competing noise. When the background is mostly non-speech, such as a fan or a vacuum cleaner, Sensia 9 switches to the established Noise Tracker II system instead, which avoids the artefacts a speech-trained AI can produce.
The practical difference shows up in the classic busy-restaurant problem. Some AI hearing aids lock onto the loudest voice in the room, even if it’s two tables away. Sensia 9 uses the direction you’re facing as a clue to which voice you actually want.
In a Resound study of 20 hearing aid users, 80% found the speaker in front of them most audible with Sensia, even when an equally loud voice came from the side. Hörzentrum Oldenburg, an independent research centre, has also backed the combined approach of four-mic focus and AI noise reduction for lower listening effort in noise.
How does Sensia 9 compare with the previous Resound Vivia 9?
Sensia 9 and Vivia 9 share the same chip and AI engine, and the microRIE looks the same. The difference is automation. Vivia 9’s AI noise reduction lived in a separate programme you had to select. Sensia 9 switches it on by itself when a conversation gets difficult. Resound states that Sensia’s sound sensing has been refined, and the range adds custom in-ear styles, which Vivia didn’t offer.
If you already wear Vivia 9, the question is whether switching programmes yourself has been a real frustration. If it has, Sensia 9 is built to solve exactly that. If you’ve been happy managing it, the upgrade is harder to justify. Your audiologist can help you weigh it up.
Who might not need Sensia 9?
If most of your listening happens in quieter settings, such as one-to-one conversations at home or watching TV, Sensia 7 or Sensia 5 may give you everything you need. Sensia 9’s biggest advantage, the automatic AI, is also only in the microRIE. So if you’d prefer a battery-powered RIE or a custom in-ear style, the gap between Sensia 9 and the lower levels is much smaller.
Models available
- Resound Sensia microRIE: Rechargeable and Bluetooth-enabled, and among the smallest rechargeable hearing aids available. It includes TapControl for calls and charges inductively.
- Resound Sensia RIE 61: A Bluetooth wireless Receiver-in-Canal (RIC) model powered by a size 312 disposable battery.
- Resound Sensia RIE 62: A slightly larger Bluetooth wireless model powered by a size 13 disposable battery, for greater power needs.
- Resound Sensia ITE (rechargeable): A custom-made In-the-Ear model with Bluetooth streaming and a dedicated custom charger.
- Resound Sensia ITC (rechargeable): A smaller custom In-the-Canal model with Bluetooth streaming and inductive charging.
- Resound Sensia ITC (disposable battery): A wireless custom In-the-Canal model for anyone who’d rather not charge. Hands-free calling isn’t available on this model.
- Resound Sensia CIC: The Completely-in-the-Canal smallest, most discreet custom model, sitting deep in the ear canal. It is non-wireless, so it doesn’t stream or connect to the app.
Which one is right for you?
The most expensive technology level isn’t automatically the right choice. If you regularly find restaurants, family gatherings or meetings hard work, and you’d rather the hearing aid handled it for you, Sensia 9 in the microRIE style is the one built for that.
If your difficult situations are predictable, Sensia 7 gives you the same AI in a programme you choose. If most of your listening is quieter, Sensia 5 may be all you need. The best way to decide is to talk through your hearing test results and everyday listening with your audiologist.
Which Sensia 9 style gets the full experience?
This is the most important point on the page. Intelligent All-Around, Intelligent Focus and AI noise reduction are only in the rechargeable Sensia 9 microRIE.
The Sensia 9 is also available in battery-powered RIE 61 and RIE 62 models and in the custom in-ear range. Those styles get Sensia 9’s other premium processing, but not the automatic AI. If the automatic AI is the reason you’re interested, the microRIE is the one to ask your audiologist about.
Battery life and charging
The Sensia 9 microRIE gives around 24 hours on a typical day, with up to 30 hours without streaming. With streaming for half the day, expect around 20 hours. Charging is inductive, so the hearing aids simply drop into place in the charger. The Premium charger holds extra charges for when you’re away from a plug.
The app
The Resound Smart 3D app covers volume, programmes, battery status and noise control. It also includes an Auracast Assistant for finding broadcast streams and remote fine-tuning, so your audiologist can make minor adjustments without an appointment.
Accessories
Sensia 9 works with Resound’s current accessories. The Auracast-enabled TV-Streamer+ streams TV sound directly to your hearing aids. The Multi-Mic+, which now has a replaceable battery, picks up a speaker’s voice from up to 25 metres away. That’s useful if you’d like extra help in noise without moving up a technology level.

Need more support with Resound Sensia 9?
The Resound Sensia 9 is designed for people who want help in noisy, multi-speaker environments without managing their hearing aids themselves. Whether it’s worth the extra over Sensia 7 depends on how often you’re in those situations, and whether the microRIE style suits you. That’s exactly what a free hearing test is for.
For more information on this hearing aid range, call us free on 0808 208 5156 to speak with one of our audiologists. Please note that there will be an additional surcharge of £125 if we are pairing a single hearing aid with an existing aid bought from another company, where we are taking over the aftercare responsibilities and looking after both hearing aids.
