Cochlear Implant Systems Explained: Cochlear, Med-EL and Advanced Bionics

When you’re considering a cochlear implant, one of the first questions that comes up is which brand is best. The short answer: all three major manufacturers produce excellent outcomes. The longer answer is that the right system depends on your anatomy, your lifestyle, and the clinical judgement of your audiologist after assessing your specific situation.

At Precision Hearing, we program cochlear implants from all three major manufacturers: Cochlear, Med-EL, and Advanced Bionics. Here’s what you need to know about each.

Cochlear (Nucleus and Kanso Series)

Cochlear is the most widely used cochlear implant manufacturer in Australia and globally. Their Nucleus series processors are behind-the-ear devices known for their reliability, connectivity options, and ongoing software development.

The latest Nucleus 8 and Kanso 3 processors are compatible with the NEXA platform, which represents a significant step forward in cochlear implant technology. NEXA is the world’s first smart cochlear implant system with several innovative features:

Upgradeable firmware — The NEXA implant can receive firmware updates after implantation, allowing recipients to access new features, improved algorithms, and optimized performance without surgical replacement. This is an industry first.

Onboard diagnostics — The implant continuously monitors its own technical performance in real-time. It can detect and respond to potential issues before they affect hearing outcomes. For example, if the implant detects suboptimal coil placement, it notifies the recipient directly through the sound processor so they can correct it immediately, rather than requiring a troubleshooting call to the clinic.

Dynamic power management — The implant continuously monitors the power required for optimal stimulation based on the patient’s individual programs and current listening needs. It then adjusts how much power it requests from the sound processor in real-time, maximizing battery life and improving consistency across different listening environments.

Internal memory — For the first time, a cochlear implant stores the patient’s programs (MAPs) internally. If a sound processor is lost or needs replacement, a new processor can retrieve the stored programs from the implant, getting recipients back to hearing quickly.

SCAN 2 environmental classification — Machine learning algorithms analyze incoming audio and automatically categorize it as Speech, Speech in Noise, Noise, Music, or Quiet, then adjust sound processing accordingly.

Cochlear also offers the Remote Check system: your processor automatically sends diagnostic data directly to your clinician between appointments. This means your clinical team can monitor device performance proactively, rather than waiting for issues to emerge at your next scheduled visit.

The Kanso 3 is an off-the-ear option: a small disc-shaped processor that sits on the head without hooking over the ear, which some recipients prefer for comfort or aesthetics.

Med-EL (SONNET and RONDO Series)

Med-EL is an Austrian manufacturer known for their flexible electrode array designs, which can be advantageous depending on cochlear anatomy. Their processors include the SONNET, a behind-the-ear device, and the RONDO, an off-the-ear option.

Med-EL’s electrode arrays are among the longest and most flexible available, designed to preserve residual hearing during insertion. For candidates who have some usable low-frequency hearing in the ear to be implanted, this can be particularly relevant to the candidacy conversation.

Advanced Bionics (Naída CI and Marvel CI)

Advanced Bionics, part of the Sonova group (which also makes Phonak hearing aids), produces the Naída CI and Marvel CI processor series. Their HiRes sound processing system aims to deliver a high-resolution signal to the auditory nerve, and their AutoSound technology automatically adjusts settings based on the listening environment.

The Marvel CI shares the same platform as Phonak’s Marvel hearing aids. This makes it particularly well suited to bimodal fitting (cochlear implant paired with a hearing aid in the opposite ear), since both devices can be managed within the same ecosystem with shared streaming from phones, TVs, and other sources.

Does the Brand Matter?

Outcomes depend far more on candidacy, rehabilitation commitment, and the quality of ongoing programming than on which brand you choose. All three manufacturers produce excellent results in appropriately selected candidates.

What does matter is that your audiologist is experienced with the system you’re fitted with. At Precision Hearing, we program all three brands, so we can have an objective conversation about which system suits your specific situation, rather than defaulting to whatever one brand happens to stock.

The final choice of manufacturer is typically made in consultation between you, your audiologist, and your ENT surgeon.

A Note on Processor Upgrades

Cochlear implant technology evolves quickly. The internal implant you receive is designed to remain compatible with future external processors as technology advances. Processor upgrades typically become available every 3 to 5 years and are usually covered by private health insurance (Silver hospital cover or higher). Understanding exactly what your fund covers is worth doing before you proceed.

Choosing a cochlear implant isn’t a one-time commitment to a single technology level. The internal component stays in place; the external processor is upgraded as better options emerge.
