ReSound Vivia vs Nexia: Why Upgrade?
TL;DR: The ReSound Vivia is a real upgrade over the Nexia, not just a spec refresh. It adds always-on AI, a far more efficient chip, and fully active Auracast. It also improves Android calling and shrinks to ReSound's smallest AI microRIE. If you are weighing ReSound Vivia vs Nexia, read on.
If you are weighing the ReSound Vivia vs Nexia, you have already done something right. You are shopping within one of the most respected hearing aid brands around. Both are premium ReSound hearing aids with sleek microRIE builds and strong Bluetooth. But they are not the same hearing aid with a new name.
The Vivia is the current generation. It is a real leap, not a coat of paint. This guide breaks down what changed, what stayed, and who should upgrade. Spoiler: it is not a close race.
How the ReSound Nexia Raised the Bar
Before we get to the Vivia, the Nexia deserves its due. When ReSound launched the ReSound Nexia, it was ahead of its time. ReSound shipped it as the first hearing aid with Bluetooth LE Audio. That opened the door to better connectivity on iPhone and compatible Android devices, plus Auracast readiness. Accelerometer-based tap controls and Windows 11 support arrived before rivals caught up.
For buyers who picked up a Nexia a generation ago, it is still a capable device. "Capable" and "current," though, are not the same thing.
What the ReSound Vivia Changed
The ReSound Vivia did not just iterate on the Nexia. It rebuilt the foundation. Here is where the gap shows up.
A Chip That's 17x More Efficient
The Nexia runs on ReSound's first-generation LE Audio platform. The Vivia uses a dual-chip design instead. One chip handles deep neural network (DNN) processing, and the other handles standard sound tasks. ReSound says that design is 17x more power-efficient than the prior platform. That efficiency buys longer battery life and more sustained AI. Math is fun when it works in your favor.
Always-On DNN Processing
This is the biggest functional difference between the two. The Nexia uses advanced sound processing, but no dedicated AI model runs constantly. The Vivia's DNN runs all the time. You don't switch it on. It is simply the baseline.
For anyone who lives in tricky sound, this distinction matters. Think noisy restaurants, crowded family gatherings, or busy offices. The Vivia works harder in every one, automatically. Nexia puts in a reasonable effort. Vivia never stops trying.
Auracast: Ready vs. Active
The Nexia launched Auracast-ready. In theory, it could receive Auracast broadcasts once a firmware update arrived. ReSound still has not shipped that update. The Vivia launched with Auracast fully active. ReSound says it was the first hearing aid to ship with Auracast enabled. To connect to broadcasts at airports, theaters, or conference halls, the Vivia does it today. The Nexia does not.
Improved Android Compatibility
The Nexia improved on ReSound's earlier Android story, but limits remained. The Vivia supports full hands-free calling on Android phones with Bluetooth 5.3 and LE Audio. Android users have long gotten a second-class hearing aid experience. The Vivia closes much of that gap.
Size: ReSound's Smallest AI RIC
ReSound says the Vivia microRIE is 25% smaller than its previous models. It calls the Vivia the smallest AI-powered receiver-in-canal hearing aid it makes. For anyone who wants a more discreet, comfortable fit, that reduction is real. It helps especially for people looking at hearing aids for small ear canals. Not a marketing line. An actual smaller device.
10 Color Options vs. Fewer
The Nexia launched with a limited color range. The Vivia offers 10 options across skin and hair tones. That makes it easier to find a shade that blends in. Small detail, big difference for wearers who care about discretion.
Intelligent Focus and the M&RIE Receiver Option
Both models support the M&RIE (Microphone and Receiver-In-Ear) receiver. It places a microphone inside the ear canal beside the receiver. It is a genuinely unusual feature, and ReSound's own research shows wearers prefer it for sound quality. The Vivia takes it further with Intelligent Focus. That feature reads head movement to sense where you want to listen, then steers beamforming to match. The Nexia's Front Focus program (Nexia 9 only) is good. The Vivia's direction-aware AI needs no manual pointing.

What Stays the Same
It is worth being clear about what did not change between these two. The shared list runs longer than the marketing suggests.
| Shared Feature | Both Models |
|---|---|
| Form factor | microRIE |
| M&RIE receiver option | Available on both |
| Tinnitus relief sounds | Included |
| IP rating | IP68 |
| iPhone hands-free calling | Full support |
| Battery life (standard) | 30 hours |
| App compatibility | ReSound Smart 3D |
| Warranty | 4-year manufacturer |
If you use an iPhone in straightforward settings, the Nexia still performs well. The Vivia's edge shows up most in noise. For anyone who works through loud restaurants, crowds, or multi-speaker rooms, the always-on DNN and Intelligent Focus pull clearly ahead.
Is the ReSound Vivia Worth the Upgrade?
For existing Nexia owners, the answer depends on your needs. If Auracast, Android calling, or better noise performance matters, the Vivia is a clear yes. iPhone users who hear well in quiet settings can wait for their next upgrade cycle. No one is judging you.
For first-time buyers comparing the two, buy the Vivia. The AI gap is real, Auracast is live, and the smaller fit is a genuine comfort win. The current-generation chip pays off across the five-plus years you will wear these devices. Future you will appreciate it. Present you may wince slightly at the receipt. That math still works out.

What is the difference between ReSound Vivia and Nexia?
The Vivia adds always-on deep neural network AI, a far more efficient dual chip, fully active Auracast, better Android calling, and ReSound's smallest AI microRIE. The Nexia was the first LE Audio hearing aid and remains capable. The Vivia is a meaningful generational upgrade over it.
Is ReSound Vivia any good?
Yes. The Vivia is ReSound's current flagship, and it earned the spot. The always-on DNN, direction-aware Intelligent Focus, and early Auracast support make it one of the most advanced hearing aids available. "Any good" undersells it a little.
What are the common problems with ReSound Vivia?
No hearing aid is without trade-offs. Battery life drops with heavy streaming and DNN use, down to around 10 hours in extreme cases. Some Android users need a newer phone with Bluetooth 5.3 and LE Audio for full hands-free calling. Talk it through with our hearing care experts before you buy.
What is the best model of ReSound hearing aid?
The ReSound Vivia 9 is the current top model. It offers the most channels, always-on AI, Ultra Focus mode, and the full Intelligent Focus suite. The Vivia 7 and 5 perform strongly at lower tiers. See how it stacks up in our Vivia 9 vs Starkey Omega AI breakdown and Signia Active Pro IX vs ReSound Vivia comparison.
What is the newest ReSound hearing aid?
The ReSound Vivia is ReSound's current flagship and the newest model in its lineup.
Is ReSound Nexia a good hearing aid?
Absolutely. The Nexia was a landmark when it launched as the first LE Audio hearing aid, and it still performs well. For buyers on a tighter budget, or iPhone users with simpler needs, it remains a capable, well-supported option.
What is the average life of a ReSound hearing aid?
Most prescription hearing aids, ReSound included, last five to seven years with proper care. The IP68 rating on both the Vivia and Nexia guards against moisture and dust, the two biggest causes of early failure. Regular cleaning and careful storage stretch that lifespan further. Our hearing care experts can review your needs and recommend the right model.
