не понятна полярность контактов микрофона, на одном плюс правый контакт на другом левый.
I checked the capsules on a test bench (which displays the sinusoid and amplitude of a working microphone). The plus and minus markings are correct (although different pins are marked on the two capsules). When the polarity is reversed, the test shows a two-fold drop in amplitude and an inversion of the sine wave. For proper operation of these capsules, it is very important to observe the polarity of the connection.
very sensitive, clear sound, Good house build quality. fast shipping.
