Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Measuring user-reported satisfaction with the latest behind-the-ear (BTE) audio processor model.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This prospective study will use a single-arm, repeated measures design with subjects serving as their own control. Participants will be experienced cochlear implant (CI) users wearing an approved BTE MED-EL audio processor. Participants will complete a take-home trial with the latest audio processor and then complete a custom questionnaire comparing design and usability to their existing audio processor.
