THANK YOU FOR CHOOSING

POLSEN.

The Polsen US-OB-33 Omnidirectional USB Boundary

Microphone connects to your computer and will

noticeably improve your audio quality during personal

video meetings and conference calls. It’s a step up

from your computer’s internal microphone, and it will

let all participants sit comfortably and talk normally

during videoconferences and calls. The microphone

runs off the power from your computer’s USB port,

and it supports plug and play, so no additional

software is needed. The internal A/D converter

boasts a 16-bit and 48 kHz sample rate for accurate,

CD-quality sound.
