Optoma Technology BM21 Bluetooth Conferencing Speakerphone

The Optoma BM21 is a Bluetooth conferencing speakerphone designed to give small teams, home offices, and traveling professionals a simple way to be heard clearly on every call.

A microphone that listens in a full 360 degree pattern captures voices from every side of the table, so participants can speak naturally without crowding the device. Conversations stay intelligible even in larger meeting rooms.

Bluetooth 4.2 delivers quick, reliable pairing with phones, tablets, or laptops. When a wired connection is preferred, the included 3.5 mm cable plugs in instantly. A wireless range of roughly 16 ft means you can place the unit where it sounds best while keeping your device close.

The internal battery provides up to 8 hours of talk time, enough for back to back meetings. When power runs low, recharge through the USB C port and get ready for the next session without long downtime.

A housing that feels compact and light slips easily into a backpack or laptop bag, letting you carry professional audio from a corporate boardroom to a client site or a kitchen table. Whether you are hosting a daily stand up, teaching a remote class, or meeting with a customer during a layover, the BM21 turns any space into a functional conference room.
