Buying the myNoise PIP RCA microphones
myNoise Plug-In Powered RCA microphones are sold as matched pairs, for USD 499 (+ shipping). They each come with a windshield and a protective pouch, the matching frequency response plot for the pair, and a three-year warranty. Each microphone is labeled with the owner's name.
myNoise microphones are built in small quantities. If you are interested in buying a pair, please contact me by email at

What will you need?
In order to connect them, you will need a simple Y Audio Cable
You will also need a portable recorder, which sends plug-in power through its microphone input; most portable recorders nowadays do. I recommend the high-end Sony Dictaphone ICD-SX1000, which I personally use (the SX733 is nice too, as is the discontinued SX712) but any of the high-end Dictaphones featuring Plug-In Power (PIP) will work fine. Most portable 'prosumer' field recorders made by Olympus, Zoom, Tascam, Yamaha, Sony, and Roland will work too. The myNoise microphones can be directly plugged into cameras and video recorders, as long as Plug-In Power is present at their microphone input.
If you are unsure about the compatibility with your audio recorder or audio device, please ask me before you make your purchase.
If you are looking for a cheaper alternative than the PIP RCA microphones, you might be interested in the mini Mics. Mini Mics are sold as matched pairs as well, but with lower matching tolerances than the PIP RCA model. They are much smaller too, and lighter, which are ideal if you plan to carry those microphones in your pocket. They sell for USD 249 (+ shipping). They come with miniature windshields and a protective pouch.
