Works. Power to the microphone in the range of 4-12 volts. If you need to connect to the car, where on-board usually 14 volts, you need to put a step-down DC/DC converter or roll. From 5 volts, excellent pashet. Connected for hands-free calls to the car. Great thing. Soldering is not cleaned.

Microphones came 2 weeks before Penza, in good condition, sensitivity is good, I use in the video surveillance system. There is no background (specially connected to a separate power supply). I recommend the seller, I will order more

The quality is excellent. Everything works. Very yes, Volen. many thanks to the seller for the efforts and work done. Good luck with your business. Evaluation for the product itself and fast shipment of 5 stars.

It arrived quickly in the national sales parcel 11.11. Everything looks like in the description. I haven't checked yet. I want to connect to a street camera, I'm waiting for suitable weather

Delivery fast... The microphone is below average. When connected to a good camera-hums like a tractor ri low useful signal level
