ReSound Vivia is the newer model (announced February 2025) and adds a dedicated deep neural network chip, Intelligent Focus and up to 30 hours of battery per charge. Nexia (announced September 2023) is the earlier platform with a four-microphone beamformer. Both offer rechargeable microRIE styles, Bluetooth LE Audio and Auracast support.
Two ReSound names keep showing up on your shortlist, and the salesperson says “Vivia is newer, Nexia is the safe pick.” Is that actually the whole story? This guide from Sound Comforts pulls apart the real differences and tells you what to confirm with the clinic, and you can ask for the latest ReSound brochure and quote once you have a model in mind.
Summary
- Vivia: announced 4 February 2025, dedicated AI chip, Intelligent Focus, up to 30 hours per charge, ReSound calls it the world’s smallest AI hearing aid.
- Nexia: announced 28 September 2023, four-microphone binaural beamformer, double-tap-the-ear call answering, wireless CROS/BiCROS.
- Both: microRIE rechargeable and non-rechargeable RIE styles, Bluetooth LE Audio, Auracast, ReSound Smart 3D app.
- Cost depends on the model level, one ear or both, and any running offer, so ask for a written quote for each.
What actually separates Vivia from Nexia?
The biggest gap is the brain inside. Vivia has a dedicated deep neural network chip that ReSound says was trained on 13.5 million spoken sentences. The Nexia pages we checked describe a four-microphone beamformer but do not mention such a chip.
| Point | ReSound Vivia | ReSound Nexia |
|---|---|---|
| Announced | 4 February 2025 | 28 September 2023 |
| Styles | microRIE (rechargeable), two non-rechargeable RIE, CROS | microRIE (rechargeable), RIE, BTE, custom, CROS |
| Sound engine | Deep neural network chip, Intelligent Focus | 4-mic binaural beamformer plus omni-directional listening |
| Battery | Up to 30 hours per charge; about 20 hours with Intelligent Focus and streaming | Not stated on the pages checked |
| Connectivity | Bluetooth LE Audio, Auracast | Bluetooth LE Audio, Auracast |
| Extras | “World’s smallest AI hearing aid” (ReSound’s claim) | Double-tap the ear to answer calls; wireless CROS/BiCROS |
These are global ReSound specs, so confirm India availability and exact styles with the clinic. Note also that “smallest” is the maker’s own claim, not an independent test.
Is Vivia’s AI actually better for noisy places?
ReSound says Vivia’s Intelligent Focus prioritises the sound you are looking at, while the chip suppresses thousands of known annoying noises. A GN study reports that 64% of users heard better in noise than with other AI hearing solutions. That is a manufacturer study, so treat it as a lead and not a promise.
Nexia is not a weak performer: its four-microphone beamformer was built for speech in busy settings too. Whether you can hear the gap between the two is something only your own noisy room will show.
How do Vivia and Nexia connect to iPhone and Android?
Both support Bluetooth LE Audio and Auracast, which lets you tune into public broadcasts such as airport announcements, where the venue supports it. LE Audio needs a compatible phone with Bluetooth 5.3 or later, and hands-free calling works with iPhone 11 or later and compatible Android phones, according to ReSound.
Both use the ReSound Smart 3D app. Bring your own phone to the clinic and test pairing before you pay, because support depends on phone model and software version.
How should you compare the cost of Vivia and Nexia?
The honest answer is that no single number exists. The cost depends on the technology level, the style, whether the quote covers one ear or both, and any offer running that week.
So compare quotes like for like. Ask for the same items on both: model level, one-ear and both-ear totals, charger, accessories such as a TV streamer, and follow-up fine-tuning. Nexia is listed in several models, and the model numbers suggest tiers, so ask what each step up actually adds for your hearing test result. A written quote for each model, side by side, tells you more than a general price list.
Not sure which of the two suits your day?
Your hearing test and your noisiest weekly situation should pick the model, not the launch year. Book a test and try both side by side if the clinic has them.

Which one fits your day: a quick pick table
| Your day | Worth discussing | Reason |
|---|---|---|
| Open office, many calls, busy restaurants | Vivia | Newer AI chip, Intelligent Focus, longer battery claim |
| Mixed routine, budget matters | A mid-level Nexia | Proven platform, easier to quote and compare |
| Mostly quiet days at home | An entry-level Nexia, or a lower family | You may not need the top technology |
| One ear much weaker than the other | Either, with CROS | Both platforms offer a CROS option |
If you have sudden hearing loss, ear pain, discharge, dizziness or loss in one ear only, see an ENT doctor first. Also keep expectations honest: neither model gives you back normal hearing, they make speech easier to follow.
What should you ask about trial, EMI and the clinic?
Sound Comforts mentions 0% EMI options and a free hearing aid trial on its ReSound page, but the page does not spell out trial length or EMI conditions for these models. Get them in writing, along with what the quote includes: one ear or two, charger, and follow-up fine-tuning.
The easiest test is to compare both in the same noisy room. You can arrange that at one of the Sound Comforts clinics.
Conclusion
Vivia is the newer, AI-driven choice with a longer quoted battery life, and Nexia is the established platform that has been fitted for longer. If your days are packed with calls, meetings and noisy restaurants, Vivia is worth hearing first. If your budget is tighter, a Nexia mid-level model may serve you almost as well, so ask for both quotes. Whichever you lean towards, start with a hearing test, compare both in your own noisy place with your own phone, and get the model level, the total cost for one and both ears, EMI and trial terms in writing.
