The Expand 80T is the Microsoft Teams variant of the Expand 80 series. It offers Bluetooth (via Bluetooth dongle that can be stored inside the speaker's compartment) or a USB-C connection with support for multipoint connectivity ideal for conferencing or multimedia and music listening. It utilizes the same 6 beamforming microphones with DSP (Digital Signal Processing) that aims to isolate reverb and ambient noise for good audio input and output. Other notable features are the 30-meters range that can support medium to large conference rooms, the dedicated MS Teams button for quick access, and the duplex performance that enables simultaneous speech.
