A the price and the delivery of adequate quality

As expected for this price, there are microphones in plastic with silver metallic paint (Figure 1). The microphone capsule (Figure 2 and 3) make a robust impression. Your frequency response is loud pack imprint (image 4) from 100 Hz to 15 kHz and the specified sensitivity of -74 dB (= 0.1995 mV / Pa) also comes out - the original cables react both microphones only on very loud sound sources. The quality of the cable is approximately three ohms (ground line), respectively about four ohms (signal line) to a cable length of three meters right inferior, thanks to asymmetric routing, they also act as receiving antennae for the ubiquitous hum.

The assignment of the XLR connector (Figure 5), which is made of 100 percent metal-free plastic, corresponds to the standard for loudspeaker wiring - Pin 1: Signal Minus, Pin 2: Signal Plus, Pin 3: open. This internal allocation is however irrelevant, since the other end of the cable hangs a sprayed-6.3 mm jack plug, which is suitable for connection to the asymmetrical inputs of mixing consoles or PA systems.

Problems could be the enclosed adapter 6.3mm mono jack to 3.5mm stereo jack prepare, since the outer cylinder of the 6.3 mm plug the "mass" - and "Signal Minus" contacts short-circuits inside the adapter. This is possibly of some devices in the "Signal Minus" contact provided supply voltage for electret, permanently short-circuited, for example Soundblaster and compatible sound cards. This can lead to malfunction, even in the worst case destroy the device, into which the plug is inserted. So you should absolutely investigate whether the middle connector on the sound card a voltage is applied before Stoppers adapter connected to the microphone into the microphone jack!

The sound quality of the original cable is terrible to my Zoom R24 (mixer). Only then, when you touch the microphone basket directly to the lips, the voice signal can prevail against the collected from around hum - of course, a plastic case with a metallic finish - as opposed to a metal-made housing - the irradiation of magnetic and electric fields not even begin to shield.

I switch on one of my home-made microphone cable, the hum is indeed weaker, but you still have to depend on the microphone basket to bring a reasonably understandable voice recording into existence. In comparison to my Behringer C-1 (condenser microphone, from 39 euros on Amazon) under the same conditions still capture sounds from two to three meters in receptive quality without an annoying hum backdrop drowned out the shots.

I for one had the microphones appointed for a hermetically sealed guitar box - so it was already before ordering my intention to exploit the microphones and professionally shielded and wired to obstruct. The two microphone capsules are certainly worth twelve euros. Of the rest - housing and wiring - you can then but do not expect high quality more as producers and distributors do not manufacture their goods in order to satisfy our greed lust. Who has no ambitions for crafting, should spend a few euros more, and one (or two) microphone (s) set with a housing made of real metal and balanced cabling.
