Understanding Resound Vivia vs. Resound Nexia Hearing Aids
Choosing between ReSound Vivia and Resound Nexia Hearing Aids often comes down to how you listen. Both models deliver ReSound’s signature natural sound and effortless wireless connection, but they take different paths to get there. The Nexia introduced Auracast™ and advanced speech processing in 2023. The Vivia, released in 2025, builds on that foundation with artificial intelligence that learns from millions of conversations to make voices clearer in noise.
These aren’t just upgrades—they’re milestones in how hearing aids understand sound. Whether you’re chatting at a family dinner or streaming music through Bluetooth LE Audio, both devices balance clarity with comfort for a more natural experience. The difference is how much help you want from built-in intelligence: Nexia is precise and proven; Vivia is adaptive and smart.

What Changed From Nexia to Vivia
ReSound didn’t just update the Nexia; it redesigned the way its newest hearing aid thinks. The ReSound Vivia introduces a Deep Neural Network (DNN) trained on millions of real-world sounds and conversations. This artificial intelligence helps the device recognize human speech patterns and separate them from noise in a more natural way—boosting what matters while softening distractions.
To power this advanced learning, Vivia includes a second processing chip dedicated solely to its AI engine. This keeps performance fast and consistent without adding size or weight. The difference is noticeable the first time you wear it: background chatter fades, and speech feels centered and clear.
How Vivia’s AI and Intelligent Focus Work Together
The DNN and Intelligent Focus system constantly cooperate to deliver lifelike sound:
- Sound Recognition: Microphones capture your full environment and send audio to the DNN for real-time analysis.
- Speech Identification: The AI detects speech cues—pitch, rhythm, and tone—then prioritizes them instantly.
- Noise Filtering: Distracting sounds such as dishes, engines, or crowd hum are identified and reduced, not removed, so your surroundings still feel natural.
- Directional Clarity: Intelligent Focus then steers microphones toward the person in front of you, maintaining a balanced sense of space while keeping speech sharp.
The ReSound Nexia, by comparison, relies on traditional digital signal processing that uses preset noise-reduction programs. It remains an excellent performer but can’t adapt quite as dynamically as Vivia’s learning-based system.

Smarter Speech Clarity With AI
Technology matters most when you can feel the difference in daily life. That’s where the ReSound Vivia stands out. Its AI-driven Intelligent Focus system automatically centers on the person speaking to you—even in noisy environments—without muting the world around you. Conversations sound clear, natural, and relaxed, whether you’re sitting in a café or walking through a busy airport.
Everyday Benefits Of AI-Enhanced Hearing
- Effortless Conversations: Voices remain crisp, even when background sounds rise or fade.
- Natural Awareness: You still hear ambient details like footsteps or gentle music, so nothing feels artificial or “blocked.”
- Automatic Adaptation: The AI adjusts faster than you could manually change settings, keeping sound comfortable as you move from one space to another.
- Balanced Listening: The DNN protects speech from distortion, so words sound smooth and realistic instead of harsh or mechanical.
For many users, the effect feels like your brain and hearing aids are working together. The Vivia’s DNN identifies speech while the Intelligent Focus microphones direct attention where you’re looking. This teamwork creates a more lifelike experience, helping you stay present in every conversation.
By contrast, the ReSound Nexia relies on advanced directionality tools such as Front Focus and 360 All-Around. These features already deliver strong speech recognition, but the Vivia adds AI “intuition” that makes conversations sound less effortful and more spontaneous.
Connectivity and Auracast Support
Clear sound means little if you can’t stay connected to what matters. Both the ReSound Vivia and Resound Nexia Hearing Aids make streaming and wireless listening simple, but they differ in how ready they are for the next wave of shared audio technology—Auracast™.
Auracast is the new global Bluetooth standard that lets you tune directly into public audio broadcasts. Imagine walking into an airport and hearing gate announcements right in your hearing aids, or catching every word of a museum tour without wearing extra headphones. With Auracast, that experience is possible.
- ReSound Nexia: Introduced Auracast-ready Bluetooth LE Audio technology. Early adopters enjoyed improved battery efficiency and high-quality sound, but Auracast broadcast connections often required firmware updates or limited venue support.
- ReSound Vivia: Expands on that promise with full Auracast compatibility from day one. You can join broadcast audio in any Auracast-enabled location and connect seamlessly to phones, tablets, and TVs without accessories.
Both models use Bluetooth LE Audio 5.2, which provides stable, energy-efficient streaming with noticeably better clarity for calls, podcasts, and music. The difference is readiness: Vivia connects now, while Nexia was built to grow into it.
The same technology powers personal listening, too. You can stream from your smartphone or TV without lag or drops. If you’re curious about how this technology is reshaping public hearing access, explore our blog on hearing aids with Bluetooth and Auracast. You can also learn more about the benefits of wireless hearing at Discover the Benefits of ReSound Hearing Aids.
Whether you’re at church, in a theater, or on a plane, the Vivia makes listening as easy as tapping “connect.” The Nexia remains an excellent companion for private Bluetooth streaming but may need updates to use public Auracast broadcasts as more venues adopt the system.
Battery Life in Real Life
For most people, the best hearing aid is the one that keeps up all day. Both the ReSound Vivia and Resound Nexia Hearing Aids offer long-lasting rechargeable batteries, but their power efficiency differs slightly because of their processing engines.
The Vivia’s dual-chip design supports AI without draining the battery too quickly, while Nexia’s single processor delivers steady performance with traditional signal processing. In typical use, both will last far longer than a full day. But, it helps to understand what “typical” really means.
Battery Life Comparison – microRIE Models
| Usage Scenario | ReSound Vivia microRIE | ReSound Nexia microRIE |
| Typical daily use | Can be up to 30 hours per charge | Up to 24 hours per charge |
| Frequent streaming or app use | About 20 hours | Around 20 hours |
| Continuous AI use | About 10 hours (with Intelligent Focus active most of the day) | Not applicable |
Even under heavy streaming or AI use, most users find their devices last from breakfast to bedtime without needing a mid-day charge. Optional portable charging cases hold multiple extra charges, making it easy to top up your hearing aids while traveling or during long workdays.
If your days involve quieter activities or minimal streaming, both models offer plenty of reserve. The Vivia simply gives you a bit more headroom, which is especially useful if you depend on Bluetooth or spend time in noisy environments that trigger its AI features.
Style, Fit, and Comfort
Comfort and appearance matter as much as performance. Both the ReSound Vivia and Resound Nexia Hearing Aids share ReSound’s signature discreet styling, yet they differ in model range and design flexibility.
The Vivia launched in a single Receiver-in-Ear (RIE) form, focusing on a compact microRIE size that blends into your hairline. It’s one of ReSound’s smallest hearing aids to date—lightweight, comfortable, and ideal for those who prefer an almost invisible device.
The Nexia, on the other hand, offers more style options. In addition to RIE designs, it comes in Behind-the-Ear (BTE) and custom In-the-Ear (ITE) models. That flexibility makes Nexia a better fit for people who need stronger amplification or prefer a molded style for easier handling.
Available Styles and Fit Options
| Model | RIE (Receiver-in-Ear) | BTE (Behind-the-Ear) | ITE (In-the-Ear) | Fit Highlights |
| ReSound Vivia | ✔️ (microRIE only) | — | — | Ultra-compact, discreet, and lightweight; ideal for mild-to-moderate loss. |
| ReSound Nexia | ✔️ | ✔️ | ✔️ | Broadest fit range, suitable for mild to severe loss and users wanting custom shells. |
For users who wear glasses or masks daily, the microRIE style is especially comfortable since it rests lightly behind the ear without pressure. Custom ITE models, available with Nexia, are often preferred by those with limited dexterity who want easier insertion and removal.
Both models maintain a secure, ergonomic shape that resists slippage and includes IP68 protection for moisture and dust. That means confidence through workouts, rain, and everyday use.
