The EPOS EXPAND SP 80 is a portable speakerphone designed to facilitate clear communication for groups of up to 16 people in a room. It utilizes six adaptive beamforming microphones with an omnidirectional capture pattern to ensure everyone is heard, while integrated digital signal processing isolates voices from ambient noise and room reverb. This device offers flexible connectivity through Bluetooth for wireless use up to 30 meters or a wired USB connection via the included detachable cable. With a frequency response ranging from 50 Hz to 20,000 Hz, it provides a broad audio spectrum for both speech and media. The black chassis measures 316 x 119 x 46 mm and weighs 980 g, making it easy to move between meeting spaces. You can rely on the internal battery for up to 18 hours of operation, and it recharges through a standard USB Type-C interface.
