The Blue Yeti Nano is a usb microphone that lets you record podcasts, stream games and create voice overs. You immediately hear how your voice sounds, because the headphone output is latency-free. This means that there is no delay between your speech and the sound reproduction of the headphones. This keeps you focused on your podcast or stream. When you register a group of speakers, you enable the omnidirectional directional characteristic. With this directional characteristic switched on, the microphone is sensitive all around. This way you register all speech regardless of which direction it comes from. Are you the only speaker or do you provide all speakers with their own Yeti Nano? Then you enable the cardioid directional characteristic. Now you take sound focused and you prevent the recording of noise.
