This is a great and cheap mic.
It’s dynamic (doesn’t need phantom power) and directional (super-cardioid) which means, it captures sound produced in front of it.
It has a good sensibility and linear response and can withstand high Sound Pressure Levels, so, can be used to everything in the mid frequency range (voice, guitar amp, trumpet, sax) but I tested it for the bass drum and bass amp and it worked very well.
The coil is mounted in a rubber holder to isolate it from unwanted noises and it has an impedance transformer. Like other mics for the same purpose, this has no on/off switch.
It is very well made, robust and its small size and light weight makes it the ideal mic to mount in difficult and small places.
It comes in a simple card board box, and brings no cable.
