I believe the electret diagram at 2:09 should have a hole in the aluminum housing under the dust cover to let the sound in. Their blog has a similar diagram but with a hole.
Good catch. Our blog version is correct, which shows the proper hole for a top sound port: www.cuidevices.com/blog/comparing-mems-and-electret-condenser-microphones#electret-condenser-microphone-basics
Nice explanation! But why is the sound port on the MEMS not above the Transducer? And why is the opening of the housing so small in both the MEMS and ECM compared to the Transducer? With large diaphragm microphones there is next to nothing in front of the capsule. Doesn't the small opening reduce the signal?
Thanks for the feedback! To answer your questions, the sound waves would still cause the diaphragm of the transducer to vibrate. It is not necessary that the port is directly above the transducer. Although they are small holes, the sound waves are still able to vibrate the diaphragms effectively.
Very informative. You didn't comment on the quality of the audio output from these two types of mics. For say, a field voice recorder, would one be better than the other? Thanks!
Glad you enjoyed the video! To answer your question, for a field voice recorder application, see below: 1. To compare with MEMS microphones (100Hz-10kHz), ECMs have a wider response frequency (100Hz-20kHz). So if the voice recorder needs to take a wider band of sound, ECM is the better option. 2. If you will use two microphones at same time, then we suggest using MEMS microphones because the consistency is superior. 3. If you consider the assembly method: For SMD type, MEMS microphone will be the priority. For pin / wire type, ECM is the only option.
Excellent explanation, thank you very much.
Glad it was helpful!
Very informative. It allows me to understand the comparison in detail. Thank you
Thanks for watching! Glad you found it helpful.

so at the same price point which sounds better?
Mems
I wish I understood this, I need to still learn the basics of audio recording to even grasp this.
Great quality 👍🏻
Thanks! We appreciate the feedback.

can we talk about the nunchucks? XD
Yes, about those... ;)
