NCT ID NCT06597747
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a new behind-the-ear audio processor (SONNET 3) is more satisfying for people who already use a cochlear implant. Twenty experienced users tried the new design and reported their satisfaction. The goal was to see if small design changes improve daily comfort and ease of use.
