Dear friends,
the voice mic on my Bose QC 35 II did mute pretty early. Only peaks were faintly audible. You cannot ajust the voice volume besides self listening. I did replace the the original board, last week , still the replacement MEMS - mic sounds awful, with a bad call-quality even in quiet environments. It sounds as if the if the noise suprression defeats the voice, even in completely quiet environments. Noise suppression for voice works indepedently from the ANC that controls environmental noise vs music. For this, condenser mics are used, see the image of the U-shaped main board. The condenser mic on the left is for picking up environmental noise for music, he part marked U500, the MEMS on the right, is for picking up environmental noise for speech. The MEMS for speech is on an extra board.
I do not know much about MEMS. There is pretty much room inside the QC 35.
I wonder if I could replace the MEMS for voice (marked MU20 6A04) with a better sounding condenser mic and, if possible, how.
Or at least replace the MEMS with a better model, though it seems they all sound pretty much the same, AFAIK.
Any ideas and advices?
Thanks a lot Salar
