The goal of this clinical trial is to learn if cochlear implant activation affects spatial orientation in cochlear implant users. The main question\[s\] it aims to answer are\]:
* Does activation of the cochlear implant improve spatial orientation?
* Is this improvement caused by better hearing ability through the cochlear implant?
Participants will:
* Take an online survey including questions about their cochlear implants and clinical questionnaires on dizziness and spatial orientation
* Undergo balance and spatial orientation tests under different cochlear implant conditions.
