Many modern USB Microphones are actually condenser microphones. They receive their power through the USB port of the computer.

A really popular USB mic is the Blue Yeti. Its an all-in-one solution, with both microphone and preamp combined.
It’s sensitive enough to pick up the nuances of the spoken voice, and is well suited for podcasts and YouTube.
