This Wireless Mic and Speaker is designed for use in small to mid-sized meetings with 1-10 participants. It connects to a computer wirelessly using a 2.4Ghz wireless connection, so it readily works with most laptops and desktops. It is plug and play through a USB 2.0 connection, so it easy to setup and use. No drivers are needed for Windows®, Mac® OS X®, Chrome OS™, and Linux®. Just enable the microphone and camera through your operating system or conferencing app to use. The microphone and speaker are specifically designed for meetings. Echo cancellation and noise reduction ensure clear audio, while the omni-directional mic is designed to pick up audio from within a 10 foot diameter to minimize background noise. The built-in rechargeable lithium battery keeps it free from wires in the middle of the conference room table. Use it wirelessly throughout the day, with up to 10 hours of talk time and 4 hours to fully recharge. It can be plugged in to a USB charger, if one is available. This wireless mic and speaker is designed to work with the Monoprice PTZ Camera (35520). The camera can be mounted on the wall next to the video monitor, while the speaker-mic is wirelessly placed in the middle of the meeting room.
