Omnidirectional, cardioid and supercardioid. It determines the sensitivity of the microphone to sound relative to the direction or angle, i.e. shows how well the microphone "hears" sound from different sides
The higher signal-to-noise ratio, the clearer sound and the bigger the dynamic range provided by the system
No higher than 32 Ohms for smartphone headphones. When using a good player or amplifier, it can be up to 100 Ohms. For stationary models you should coordinate the impedance with the amplifier power
