Q. Why do we use a mini microphone?

The fact that it is smaller is the primary factor that led to the decision to go with a mini microphone. Lightweight is typically associated with being of a miniature size. A lightweight and portable microphone is one that can be easily transported. Even if you want to produce an outside vlog using your cell phone you won't become worn out from filming for an extended period of time using it. A further advantage of the small microphone is that it is more long-lasting than its connected counterpart. When a cabled microphone is used frequently the wires often become frayed. This is especially true if the microphone was poorly manufactured. Since of this the cable will eventually need to be replaced or repaired on a regular basis because it will become worn out.
