ReSound Enzo IA: The World’s Smallest Rechargeable Super Power Hearing Aid Unveiled

GN Hearing officially launched its new generation super power hearing aid, ReSound Enzo IA, on August 12, 2025. Described by the company as “the world’s smallest rechargeable Super Power hearing aid”, ReSound Enzo IA is designed for people with severe to profound hearing loss and aims to deliver significant improvement in speech understanding in noisy environments. For users in the super power segment, understanding speech in noise is one of the biggest challenges; GN states that, thanks to its Organic Hearing philosophy, the Enzo IA overcomes this issue without compromising device size or battery life. As a result, ReSound Enzo IA provides users who require high output with enhanced sound quality while maintaining a small, stylish design for comfortable wear.

Key Highlights:

  • AI-Powered Processing: The Enzo IA uses GN’s new 360 processor and Intelligence Augmented (IA) artificial intelligence platform to analyze environmental sounds in real time. With machine learning, it automatically classifies and adapts to different acoustic environments, delivering the best possible listening experience in every situation . This reduces the listening effort required for users with severe hearing loss, especially in noisy environments.
  • Superior Performance in Noise: The device features Clear Focus, an extremely narrow beamforming directional microphone technology. It focuses on speech coming from the front while suppressing distracting background noise, greatly improving speech understanding in noise. In tests, 93% of super power users preferred listening in noise with the Enzo IA, and it delivered a 2.7 dB improvement in signal-to-noise ratio compared to its predecessors.
  • Compact Design & Long Battery Life: Despite its high power output, ReSound Enzo IA comes in a much smaller housing than battery-powered counterparts. With a built-in lithium-ion battery, it delivers up to 28 hours of use on a single charge (~20 hours with heavy streaming). This eliminates the need for mid-day battery changes and offers peace of mind for all-day use.
  • Advanced Connectivity: Enzo IA is the first super power hearing aid to support Bluetooth Low Energy (LE) Audio and Auracast broadcast technology. Users can connect directly to public venue audio broadcasts through the ReSound Smart 3D smartphone app. The device is also compatible with accessories like Multi-Mic+ and TV-Streamer+, can connect to two devices at once, and allows one-touch call answering directly on the hearing aid.

AI-Enhanced Sound Processing

At the heart of the ReSound Enzo IA is GN’s Intelligence Augmented™ (IA) AI-driven sound platform. This platform, working with the 360 dedicated processor chip, constantly listens to and analyzes the surrounding sounds, automatically adapting to various listening environments. For example, when moving from a quiet office to a busy restaurant, the device detects the change and switches to optimal settings without user intervention. Developed under GN’s “Organic Hearing” approach, this continuous optimization aims to reduce cognitive load and make following conversations less fatiguing for people with severe hearing loss.

Thanks to this intelligent platform, Enzo IA delivers advanced noise management and the world’s best feedback management system. In high-gain hearing aids, unwanted “whistling” feedback is common; GN’s system allows for more stable gain (additional amplification without distortion or feedback) than competitors. This is particularly important for users with profound hearing loss, as it enables higher amplification when needed.

Superior Performance in Noisy Environments

For those with severe hearing loss, distinguishing speech in noisy, crowded settings can be a major struggle. ReSound Enzo IA addresses this with Clear Focus, a state-of-the-art directional beamforming feature. According to GN, Clear Focus is the narrowest beamformer in the industry, focusing on the talker in front while suppressing disruptive sounds from other directions . This targeted listening mode makes it much easier to follow conversations in noise. In company tests, 93% of users chose the Enzo IA for listening in noise, and it delivered a 2.7 dB improvement in SNR (signal-to-noise ratio) compared to previous high-power models. In some measurements, combining Clear Focus with high gain capacity provided up to an 8 dB SNR advantage —a significant improvement in noisy listening situations.

Compact Design & Long Battery Life

The ReSound Enzo IA stands out as one of the most compact devices in its class. According to GN Hearing, Enzo IA has the smallest rechargeable design among current super power hearing aids. This allows people with severe hearing loss—who previously had to wear larger, bulkier devices—to enjoy a smaller, more discreet hearing aid. The compact body improves comfort behind the ear and offers an aesthetic advantage. Importantly, size reduction does not come at the cost of performance; power output and amplification capacity remain as high as larger super power devices.

One of the device’s biggest advantages is its powerful rechargeable battery. A single charge provides around 28 hours of continuous use, or about 20 hours with a half-day of direct streaming. This delivers a true “all-day battery” experience, eliminating the need for mid-day battery swaps. For travelers and active users, reduced battery anxiety means greater independence and confidence. The device comes with an inductive desktop charger, whose closed design helps protect against dust and moisture for reliable charging every time. Additionally, nano coating technology on the device surfaces provides water and sweat resistance, ensuring it withstands daily challenges.

For style and personalization, Enzo IA offers 10 different color options, allowing users to match their hearing aid to their hair or personal style. Whether blending in with natural tones or making a bold fashion statement, users can customize their look. Especially in the BTE form factor, having tones that complement various hair and skin colors makes the device easier to embrace and integrate into daily life. Ultimately, ReSound Enzo IA combines high performance with user-focused design.

Advanced Wireless Connectivity

ReSound Enzo IA is equipped with the latest wireless technology, including Bluetooth Low Energy Audio—making it the first super power hearing aid to support Bluetooth LE Audio. Bluetooth LE Audio consumes less power than classic Bluetooth while offering higher sound quality and the ability to broadcast to multiple devices simultaneously. The Auracast™ feature enables real-world use of this broadcast function, allowing users to connect directly to public venue sound systems via the ReSound Smart 3D app. For example, museum audio guides, airport announcements, or conference hall audio feeds can be accessed directly through the hearing aid if the venue supports Auracast.

Enzo IA offers broad compatibility with accessories and devices. For instance, it works with the ReSound Multi-Mic+ remote microphone for direct speech pickup in noisy settings or meetings. This accessory also includes a Telecoil, enabling connection to loop systems found in churches, theaters, and cinemas. For home TV listening, the ReSound TV-Streamer+ streams audio directly to the hearing aid, delivering clear sound independent of background noise . Enzo IA can connect to two devices simultaneously (e.g., phone and tablet) and allows switching between them without disconnecting. It also enables hands-free calling, letting users answer calls with a press of the button on the device and speak directly through its microphones.

User Experience & Launch Details

The real-world impact of the ReSound Enzo IA can be seen in user feedback. Helen Cherry, one of the first users, says the device has “changed her world”. She adds, “These hearing aids have changed my life; I couldn’t hear anything without them”. Cherry highlights that small-seeming technological improvements can significantly ease daily life for those with profound hearing loss, saying, “ReSound Enzo IA has enriched my auditory experience in ways I never thought possible”.

GN Hearing announced that the ReSound Enzo IA will be available first in the U.S. and Germany starting August 21, 2025. It will roll out to other markets in the coming months; while no exact date is set for Turkey, the phrase “in the near future” suggests it is expected soon. The Beltone equivalent, Beltone Boost Max S, will launch on the same date in the U.S. and Germany before expanding elsewhere . As one of the global leaders in hearing healthcare, GN Hearing aims to improve end-user hearing experiences and provide professionals with advanced solutions. With its innovations, Enzo IA sets a new benchmark in the super power hearing aid segment.
