With a combination of pinna restoration, binaural compression and a dynamic optimisation of directionality settings, the 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 clients 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 analyse and accurately classify the listening environment, automatically adjusting gain and noise reduction settings.


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

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

Improves your clients’ 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 minimise 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.


Users 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 professionals increased fitting flexibility to easily meet user preferences for amplification. The strong sound quality preferences of users with severe and profound losses can be matched with this array of options.

Increases the gain of frequencies below 1000 Hz.

Users get a richer sound quality experience. Provides professionals with a quick tool to meet user preferences for louder and fuller sound.


Wireless connectivity

ReSound ENZO2 allows your clients to connect directly with an iPhone, iPad or iPod touch, and makes their Smart Hearing aids work just like wireless headphones. With them, your clients 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 when making calls*. This could make the difference between a successful call and no conversation at all.

If your clients 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 clients 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.

Easy fitting with Aventa

Aventa 3.10 integrates seamlessly with Airlink 2 wireless fitting accessories so you can provide your clients with more comfortable, less intrusive sessions. 


Slim, comfortable and highly durable

ReSound ENZO2 is the smallest and most powerful 675 battery super power hearing aid available. And if your clients need less gain, the same benefits are delivered in a small 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 several accessories that will benefit your clients:

  • A selection of earhooks, including a metal hook for high power configuration of the 13 battery model
  • An FM receiver 
  • A DAI (Direct Audio Input) and Programming Connector


The ReSound Smart app

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

They can save and geo-tag favourite programmes, 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 client to control their hearing experience from their wrist.
