Cardioid Condenser Microphone
The BM-800 is a very low-cost electret condenser microphone that is sold under a variety of brand names on Ebay and Amazon. It is remarkable for its price — under $20, including a shockmount.
The packaging of our sample microphone describes the BM-800 as a “large diaphragm” design. This is untrue; the capsule is a 16mm, small diaphragm electret model.
The circuit does not supply polarization voltage to the capsule; would-be DIY upgrade enthusiasts are limited to other electret choices, unless the mic’s circuit is replaced too.
