A Richer, Fuller Hearing Experience
Behind every audio processor is a cochlear implant that acts as a bridge between technology and nature. Choosing the right one is a pivotal moment in your patient’s hearing journey. The SYNCHRONY 2 cochlear implant is designed to provide your patients with their best hearing at every turn.
Closest to Natural Hearing
Natural hearing uses the whole cochlea—and so does SYNCHRONY 2. Our unique approach follows nature for more natural sound perception and better speech understanding.
Outstanding MRI Safety
Most people will need an MRI in the next 10 years. That’s why the SYNCHRONY 2 cochlear implant can undergo 3.0 Tesla MRIs** without magnet removal.***
Leading in Cochlear Implant Reliability
All our latest-generation titanium implants have an overall cumulative survival rate of over 99%. That’s reliability unmatched by any other cochlear implant manufacturer.
