ReSound ENZO2 - Super Power Smart Hearing

ReSound ENZO2™ lets you bring the next generation of Smart Hearing aids to your patients with severe and profound hearing loss. With top-rated sound quality, a durable design, personalized control and more ways to connect to the world, it’s a hearing experience like no other.


Built for understanding

Spatial Sense in ReSound ENZO2 is developed to give patients a greater understanding of where sounds are coming from, even from behind. Together with other key audiological features, it delivers a rich, balanced sound. Your patients will feel more at ease even in challenging sound environments.

With an unrivaled performance of 10% higher maximum stable gain than other wireless super power hearing aids*, your patients will enjoy better speech understanding and greater amplification without noise and feedback.

With a combination of pinna restoration, binaural compression and a dynamic optimization of directionality settings, hearing aids with Binaural Directionality™ II with Spatial Sense™ continuously exchange data to restore spatial cues and select the best directional response for any listening environment.


Delivers vivid spatial awareness with exceptional sound quality, and as background noise levels rise, your patients can zoom in on the sounds they are interested in without losing a sense of what is going on around them.


Hearing aids with Binaural Environmental Optimizer™ II work together to analyze 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.


Noise Tracker™ II is a unique spectral subtraction technology that reduces unwanted noise without degrading the speech signal.

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


With Sound Shaper™ high-frequency sounds that are not audible due to high-frequency losses or cochlear dead regions are moved down in the frequency spectrum. A proportional relationship between input and output frequencies is maintained to minimize distortion.

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


DFS Ultra™ II is a unique 2-channel, 2-filter system that cancels acoustic feedback with extreme precision.


Patients can now enjoy extra comfort, better audibility and all the subtle nuances of rich sound, even in the most challenging situations.


WDRC fits a wide range of input sounds into the limited dynamic range of the user. Linear and semi-linear strategies decrease the amount of compression applied. Four time-constant schemes provide exceptional fitting flexibility.


Gives you increased fitting flexibility to easily meet patient preferences for amplification. The strong sound quality preferences of patients with severe and profound losses can be matched with this array of options.

Increases the gain of frequencies below 1000 Hz.

Patients get a richer sound quality experience. Provides you with a quick tool to meet patient preferences for louder and fuller sound.


Wireless connectivity

ReSound ENZO2 allows your patients to connect directly with an iPhone, iPad or iPod touch, and makes their Smart Hearing aids work just like wireless headphones. Your patients will be able to enjoy phone and video calls like never before. The visual cues provided by a FaceTime video call have been shown to have significant benefits for people with severe and profound hearing loss*. This could make the difference between a successful call and no conversation at all.

If your patients don’t have an iPhone, they can still stream phone calls and music from their Android smartphone or any other Bluetooth-enabled phone by using the ReSound’s Phone Clip+.

ReSound wireless accessories

With ReSound ENZO2 your patients can connect directly to all ReSound wireless accessories for direct audio streaming and discreet control over their listening experience – without using a neckloop. With a full ecosystem of wireless connectivity, including the new ReSound Micro Mic and Multi Mic, they can extend their listening experience and hear everything more clearly.


Small, discreet and built for reliability

ReSound ENZO2 is the smallest and most powerful 675 battery super power hearing aid available. And if your patients need less gain, the same benefits are delivered in a smaller 13 battery model. Every component of our hearing instruments is sealed off from moisture by iSolate nanotech, an ultrathin polymer shield, which also protects them from damage caused by cerumen and dust.

ReSound ENZO2 comes with accessories that will benefit your patients:

  • An FM receiver 
  • A DAI (Direct Audio Input) and Programming Connector



The ReSound Smart app

The ReSound Smart™ app enables your patients to adjust volume, treble and bass on the go and allows easy fine-tuning of speech focus and comfort in noise and wind. 

They can save and geo-tag favorite programs, control their ReSound wireless accessories, find misplaced hearing aids and much more. All without having to touch their hearing aids.

The ReSound Smart app is even available for Apple Watch and empowers your patients to control their hearing experience from their wrist.
