Why people choose it Nucleus 7
Direct sound streaming
Calls, music and video stream straight into the processor from compatible Apple devices (Made for iPhone) and selected Android devices (ASHA). That means clear sound with no extra accessory in between.
Automatic adaptation to your surroundings
SmartSound iQ with SCAN recognises your environment — quiet, speech, noise, music — and adjusts the settings automatically. There is no need to switch programmes by hand.
Flexible power
The processor runs on rechargeable batteries or disposable zinc-air batteries. You choose whichever option suits your day.
Water and dust protection
The body carries IP57 protection, rising to IP68 with the Aqua+ accessory. That brings confidence in the rain, during sport and around water.
Key features
Dual microphones and ForwardFocus
Two microphones help to lift out speech, while ForwardFocus reduces noise coming from behind. This makes conversation easier in busy places.
Made for iPhone and ASHA
Direct connection to compatible iPhone and iPad, and to selected Android devices over the ASHA protocol. Sound reaches the processor without an extra receiver.
Nucleus Smart App
The app for iOS and Android lets you control the processor, see battery status, keep a data log and follow hearing with the Hearing Tracker. Find My Processor helps to locate a misplaced processor.
Bimodal solution
Nucleus 7 works in tandem with a compatible ReSound hearing aid on the opposite ear. This unites the implant and hearing aid into a single hearing solution.
A choice of colours
The processor is available in several colours to blend with hair or skin tone. You can choose a discreet or a more expressive look.
