These did not come as two pieces you need to get a soldering iron to put it together. Additionally pins are not angled as shown.

I use these little guys to do sound detection in microcontroller projects. I highly recommend adding a 100uF capacitor between GND and (5V) SRC to smooth out the signal.

I bought them to use in a project. The project is a sound-reactive LED controller based on the ESP866 controller. It worked out very well. 4 stars as I find the price a bit high for such an item.
