Technology that makes a real difference

For many people with severe-to-profound hearing loss, hearing aids aren’t just about amplifying sound, they’re also about providing clarity.

Our patented Binaural Directionality III and Spatial Sense technology give patients a clearer sense of where sounds are coming from, while delivering the highest amplification without feedback.

With ReSound ENZO 3D, your patients experience:


more clarity of the sounds around them*


better speech understanding in noise**

Speech understanding improves by 70% when using ReSound ENZO 3D compared to an acoustic phone*.

Your patients can effortlessly enjoy even more ways to communicate.

The smallest option available

ReSound ENZO 3D is available in two Behind-the-Ear (BTE) styles and a wide range of colors, with iSolate nanotech coating for protection against water, dust, and earwax.

ENZO 3D - Key features

  • ADVANTAGE: Continuous ear-to-ear exchange of data about the environment optimizes polar patterns and microphone settings in any listening situation.


    Your patients can focus on the sounds that are important to them without losing touch with what’s going on around them. Providing the brain with the right information from both ears lets your patients effortlessly follow conversations and shift attention naturally.

  • ADVANTAGE: Combines algorithms that restore pinna cues and interaural level differences to provide the brain with natural acoustic information for spatial hearing.


    Supports your patients’ ability to detect where sounds are coming from, so they experience a more natural sense of their surroundings and the best possible sound quality.

  • ADVANTAGE: The hearing aids work together to analyse and accurately classify the listening environment, automatically adjusting gain and noise reduction settings.


    Your patients can enjoy optimal audibility and listening comfort even when moving through rapidly changing sound environments.

  • ADVANTAGE: A unique spectral subtraction technology reduces unwanted noise without degrading the speech signal.


    Improves your patients’ comfort in noisy listening situations without compromising speech understanding.

  • High frequency sounds that are not audible due to high frequency losses or cochlear dead regions are compressed in the frequency spectrum. A proportional relationship between input and output frequencies is maintained to minimize distortion.


    This improves the audibility of speech cues that would otherwise have been lost, while maintaining the best sound quality possible.

  • ADVANTAGE: High precision feedback path analysis enables DFS Ultra II to cancel feedback with extreme accuracy. Music Mode analyzes the sound over a longer period of time, so the system can better distinguish true feedback from music and other tonal sounds.


    Patients can now enjoy extra comfort, better audibility and all the subtle nuances of rich sound, even in the most challenging situations. Music Mode provides patients with clearer, richer, distortion-free music experience.

  • For better personalization to your patients’ needs, ReSound ENZO 3D also offers compression modes as alternatives to WDRC that decrease the amount of applied compression – Semi-linear and Linear

    This makes fitting more flexible by compensating for different loudness sensitivities, so you can provide comfortable sound levels for your patients.
  • A convenient tool to quickly fine-tune the gain of frequencies below 1000 Hz.

    This makes it easier for you to meet your patients’ preferences and provide a richer and fuller experience in sound quality.

"This is the first time I've been extremely excited about hearing aid technology"

ReSound Assist

More connections for better care

With ReSound Assist, our comprehensive tele-audiology solution, you can offer your patients a full suite of hearing care options that include: in-office appointments, live video appointments and remote fine-tunings.

Face-to-face, real-time hearing care

Sometimes it can be difficult for a patient to get to the clinic. Now there is a flexible way for you to remain accessible and visible, and make sure your patients get the care they need. Live Assistance allows you to connect with your patient via a video call to remotely fine-tune their hearing aids directly from your ReSound Smart Fit software.

Send fine-tuning adjustments anytime

Offer your patients an even greater level of service by sending fine-tuning adjustments directly to their ReSound Smart 3D app to download.

Give your patients seamless connectivity

Speaking on the telephone is a challenge for people with severe-to-profound hearing loss. With MFi® technology, ReSound ENZO 3D works like wireless headphones and sound is streamed directly to the hearing aids.

ReSound ENZO 3D is the only Made for Apple® hearing aid for people with severe-to-profound hearing loss. (Android users can stream with the ReSound Phone Clip+.)

Patients can also use the ReSound Smart 3DTM app to personalize and control their hearing aids by adjusting volume as well as bass, middle and treble.
