K. had the switch-on day yesterday. I have asked him about his first experiences some 4 hours later and he texted me:
The processor was switched on, but I don’t hear much besides the sounds typical for the interference noises. It is supposed to change with time. The magnet part does not hold well, despite some magnets added. Now, after a few hours, I start to understand a bit (but not much) of speech, but the interference noises make wearing the processor quite difficult. In general, the clanks, cracks and squeaks confuse one completely.
Good luck! I wonder how it will be going and if my impressions would be similar.
