Jak słyszę przez implant - dwa lata później - YouTube
EDIT:
How I hear through the cochlear implant - two years later (youtube.com)
There are link to clip from SSD person from my country (with closed captions in english) “How I hear by CI - two years after surgery”
My experiences are slightly different, e.g. I hear quite well guitar an piano, but I can’t distiguish pitches (maybe yet - it’s very difficult given I have 22 electrodes compared to 3500 inner hair cells).
