What this Trial Is About
The goal of this clinical trial is to compare speech perception and user satisfaction between two sound paths, Nuc8 (Cochlear Nucleus sound path) and Neu2 (Neuro 2 sound path), in adult users of the NeuroZti cochlear implant. Following Cochlear's acquisition of Neurelec, there is a need to support existing NeuroZti implant users who currently rely on the Neuro 2 sound processor. The Nuc8-based sound processor, currently in development, is designed to be compatible with the Neuro system while integrating with Cochlear's ecosystem of tools and applications developed over the past decade. To ensure long-term support and maintainability, transitioning to the Nuc8 sound path is preferred. However, changes in sound paths may impact sound quality, speech perception, and user acceptance. The main question this study aims to answer is: how does speech performance and user satisfaction compare between the Nuc8 and Neu2 sound paths? Participants will: * Undergo speech perception testing in quiet environments * Provide ratings on comfort and overall satisfaction The study involves a single visit lasting approximately 3 hours.
