Any recommendations for microphones that are (a) high-quality, (b) cheap (under US$5.00), (c) small (under a cubic centimeter), and (d) with analog output (such as a 1/8-inch plug)? Note that high-quality and cheap are not contradictory requirements. iPhones and other smartphones have extremely high-quality microphones (and they are tiny) and must certainly cost much less than $5 as a part, but they seem impossible to find. Every off-the-shelf mic under $5 that I've tried has been garbage in terms of sound quality, and even much more expensive ones have not been great. Good mics certainly exist. Here's a compact analog microphone I own that has fantastic sound quality: http://www.amazon.com/Sony-Electret-Condenser-Microphone-ECM-C115/dp/B00012FVRE http://www.amazon.com/Sony-Electret-Condenser-Microphone-ECM... But it's ridiculous that this microphone costs 6x as much as the CHIP and 10x as the RPi Zero. You can't build a product around the CHIP or the RPi if an essential part is that expensive.
