I decided to purchase the DAYTON AUDIO iMM-6 MIC. My lifelong favorite hobby, of sorts, is messing around with audio electronics and speaker systems.I was using a similar sized condenser mic (Yamaha YPAO) which was included with my Yamaha 5.1 receiver. However, I've never been certain of the accuracy of the YPAO. It is made exclusively for the Yamaha receiver, and not for independent measurements.This DAYTON AUDIO iMM-6 mic, on the other hand, is made exactly for such a purpose. The iMM-6 comes with a calibration file which may be downloaded, for free. The file I downloaded is unique to my mic. To my understanding, Dayton Audio's lab measures the response of each and every iMM-6 mic (from 20Hz to 20kHz) and compares the response to a professional grade mic. All deviations are then logged into a calibration file, to be obtained by the user. This file is unique and may only be obtained via the unique serial number of my mic. This calibration file may be downloaded into an analyzing computer program or into an Android or Iphone audio analyzer app, or simply downloaded and printed.The mic itself is tiny, maybe 2 inches long. It arrives in a nice little metal box. Within, is a thick foam liner which safely holds the mic in place. It neatly plugs into the headphone/mic jack of most phones (your phone must have a TRRS jack, which allows simultanious recording and transmissions) .This mic comes with a female 3.5mm jack to which you may connect headphones (to monitor what you are recording) or connect to an amplifier input if your computer/ phone program/app is able to generate various test frequencies/ signals.As far as pickup sensitivity and overall performance. Sensitivity of the iMM-6 is def higher. As much as 10dB higher than my YPAO, depending on frequency. Since the iMM-6 mic includes the calibration file and is claimed to be accurate to within 0.5dB, my comparison of test signals has made me realize my YPAO mic is quite a bit off. Much more so than previously believed.So, I believe this little mic is well worth the $20. I am now ordering an extension cable (TRRS to TRRS, male to female), to allow more flexibility of use. Any such cable/adapter must be TRRS on both ends. TRS will not work. TRRS is a 4 conductor cable and connector.I prefer using my laptop over a phone because the phone's internal circuit does not allow for a flat 20Hz to 20kHz response, whereas my laptop allows bypass of the limiter circuitry.Highly recommended
