Hi everyone,
for one year i had the the problem that callers couldnt here me sometimes or gave me the feedback that the sound quality is really poor. But my mics passed all the microphone tests and i always heard them quite clearly. I didnt know what was going on. The solutions for me was to increase the microphone holes of the fp4 case (see pictures), because the case has gotten really wobbely over the last three years and blocked the holes. Now everyone can hear me cristal clear.
Kind regards
Milan
