Part values are not critical. Change the resistor for other voltages. Use 4.7K for 5-6V, etc.
Perfect for surveillance work. Nice replacement MIC for just about any electret circuit. Cost effective for all kinds of HAM, experimenter and hobby projects.
This auction is for microphones only. The other parts are NOT included.

Below is an example of just how small these microphones are. I replaced the original "miniature" microphone of my tiny Transmitter 'BUG'. Compare the size of the mic to the button battery to the right.
