ReSound Vivia vs Nexia: Why Upgrade?

TL;DR: The ReSound Vivia is a meaningful upgrade over the Nexia, not just a spec refresh. It brings always-on AI processing, a 17x more efficient chip, fully active Auracast, improved Android compatibility, and the world’s smallest AI-powered microRIE form factor. If you’re wondering about ReSound Vivia vs Nexia, read on.

If you’re weighing the ReSound Vivia vs Nexia, you’ve already done something right: you’re shopping within one of the most respected hearing aid brands in the world. Both are premium ReSound hearing aids with solid performance, sleek microRIE form factors, and strong Bluetooth connectivity. But they are not the same hearing aid with a new name.

The Vivia, released in 2025, represents a genuine generational leap, and the differences matter for real-world listening. This article breaks down exactly what changed, what stayed the same, and who should upgrade. Spoiler: it’s 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 in 2023, it was genuinely ahead of its time. ReSound shipped it as the first hearing aid with Bluetooth LE Audio, which opened the door to better connectivity on iPhone and compatible Android devices, plus Auracast readiness. Accelerometer-based tap controls and Windows 11 compatibility arrived before competitors had caught up.

For buyers who purchased a Nexia two years ago, it’s still a capable device. “Capable” and “current,” though, are not the same thing.

What the ReSound Vivia Changed

The ReSound Vivia didn’t just iterate on the Nexia. It rebuilt the foundation. Here’s where the gap shows up.

A Chip That’s 17x More Efficient

The Nexia runs on ReSound’s first-generation LE Audio processing platform. The Vivia uses a dual-chip architecture — one dedicated to deep neural network (DNN) processing, one handling standard sound tasks — that ReSound says is 17x more power-efficient than its predecessor. That efficiency translates directly into longer battery life and more sustained AI processing without draining the device. Math is fun when it works in your favor.

Always-On DNN Processing

This is the biggest functional difference between the two models. The Nexia uses advanced sound processing, but it doesn’t run a dedicated AI model continuously. The Vivia’s DNN runs all the time, trained on 13.5 million sentences and 25 years of acoustic research. It’s not a mode you activate. It’s the baseline.

For anyone who navigates complex listening environments — a noisy restaurant, a crowded family gathering, a busy office — this distinction matters. The Vivia works harder, automatically, in every environment. The Nexia makes a reasonable effort. The Vivia never stops trying.

Auracast: Ready vs. Active

The Nexia launched Auracast-ready, meaning it could theoretically receive Auracast broadcasts once a firmware update arrived. ReSound still hasn’t shipped that update. The Vivia launched with Auracast fully active, making it the world’s first hearing aid to ship with Auracast functionality enabled at launch. To connect directly to Bluetooth broadcasts at airports, theaters, or conference venues: the Vivia does it today. The Nexia does not.

Improved Android Compatibility

The Nexia improved on ReSound’s earlier Android story, but limitations remained. The Vivia supports full hands-free calling on Android devices running Bluetooth 5.3 or higher with LE Audio support. Android users have historically gotten a second-class experience with hearing aids. The Vivia closes that gap considerably.

Size: The World’s Smallest AI-Powered RIC

The Vivia microRIE is 25% smaller than previous ReSound models. ReSound calls it the world’s smallest AI-powered receiver-in-canal hearing aid. For anyone who has struggled with comfort or wants a more discreet fit, particularly those looking for hearing aids for small ear canals, the size reduction is a legitimate quality-of-life improvement. Not a marketing claim. An actual smaller hearing aid.

10 Color Options vs. Fewer

The Nexia launched with a limited color range. The Vivia offers 10 color options across skin and hair tones, making it easier to find a match that blends naturally. Small detail. Big difference for wearers who care about discretion.

Intelligent Focus and the M&RIE Receiver Option

Both the Vivia and Nexia support the M&RIE (Microphone & Receiver-In-Ear) receiver, which places a microphone inside the ear canal alongside the receiver. It’s a genuinely unique feature in the hearing aid market, and ReSound’s own research shows users prefer it for sound quality. The Vivia takes this further with Intelligent Focus, which uses head movement detection to determine where you want to direct your attention and adjusts beamforming accordingly. The Nexia’s Front Focus program (Nexia 9 only) is good. The Vivia’s direction-aware AI doesn’t need you to manually point it anywhere.

If you’re an iPhone user in relatively straightforward listening environments, the Nexia still performs well. The Vivia’s advantages compound most noticeably in noise. For anyone who regularly navigates loud restaurants, crowded venues, or multi-speaker conversations, the always-on DNN and improved Intelligent Focus make a meaningful difference over the Nexia’s approach.

Is the ReSound Vivia Worth the Upgrade?

For existing Nexia owners: if Auracast, Android hands-free calling, or better noise performance in complex environments matters to you, the Vivia is a clear yes. iPhone users who primarily hear in quieter settings and have no complaints about their Nexia can reasonably wait for their next natural upgrade cycle. No one is judging you.

For first-time buyers comparing these two: buy the Vivia. The AI processing gap is real, Auracast is live, and the smaller form factor is a genuine comfort improvement. Spending up to get the current-generation chip pays dividends over the five-plus years you’ll wear these devices. Future you will appreciate it. Present you may wince slightly at the receipt. That math still works out.

It’s also worth noting that the Vivia sits at the top of the ReSound lineup, but ReSound isn’t the only brand worth considering. Our ReSound vs Signia comparison and Phonak vs ReSound breakdown are good next reads if you want to see how these stack up against other manufacturers.

The Vivia features always-on deep neural network AI processing, a 17x more efficient dual chip, fully active Auracast, improved Android hands-free calling, and the world’s smallest AI microRIE form factor. The Nexia, released in 2023, was the first LE Audio hearing aid and remains a capable device. The Vivia represents a meaningful generational upgrade over it.

Is ReSound Vivia any good?

Yes. The Vivia is ReSound’s current flagship, and it earned that position. The always-on DNN trained on over 13 million sentences, direction-aware Intelligent Focus, and first-to-market Auracast support make it one of the most advanced hearing aids available today. “Any good” undersells it a bit.

What are the common problems with ReSound Vivia?

No hearing aid is without tradeoffs. Battery life drops significantly with heavy streaming and DNN processing, down to around 10 hours in extreme use scenarios. Some Android users may also find that full hands-free calling requires a newer phone with Bluetooth 5.3 and LE Audio support. Worth discussing with a hearing care provider before purchasing.

What is the best model of ReSound hearing aid?

The ReSound Vivia 9 is the current top-of-line model, offering the most processing channels, always-on AI, Ultra Focus mode, and the full suite of Intelligent Focus features. The Vivia 7 and 5 are strong performers at lower price points. See how it compares to competing brands in our Vivia 9 vs Starkey Omega AI breakdown and our Signia Active Pro IX vs ReSound Vivia comparison.

What is the newest ReSound hearing aid?

The ReSound Vivia, released in 2025, is ReSound’s current flagship and the newest model in their lineup.

Is ReSound Nexia a good hearing aid?

Absolutely. The Nexia was a landmark device when it launched in 2023 as the world’s first LE Audio hearing aid, and it’s still a strong performer. For buyers on a tighter budget or iPhone users with simpler listening needs, it remains a well-supported, capable option.

What is the average life of a ReSound hearing aid?

Most prescription hearing aids, including ReSound models, have a practical lifespan of five to seven years with proper care. ReSound’s IP68 rating on both the Vivia and Nexia protects against moisture and dust, which are the two biggest factors in premature device failure. Regular cleaning and proper storage extend that lifespan considerably.
