The EPOS EXPAND SP 40+ is a portable wireless speakerphone designed to facilitate clear communication during group calls. It utilizes three beamforming microphones that work together to isolate human voices from ambient noise and room reverb, ensuring that your colleagues hear you clearly regardless of the environment. You can connect it via Bluetooth for wireless freedom or use the included USB-C cable and dongle for a stable wired connection. This compact device weighs approximately 314 g and measures 120 mm in diameter and 37 mm in height, making it easy to carry between meeting rooms or pack for travel. The black finish is complemented by intuitive push buttons for call control and LED indicators that let you know at a glance if you are on a call or muted. With a built-in Lithium Polymer battery, the speakerphone provides up to 18 hours of talk time, which is plenty for a full day of intensive meetings. When it needs power, a full charge takes about 3 hours and 20 minutes via the USB Type-C port. Because it supports up to 8 people, it is a practical choice for small teams who need a reliable tool for collaborative discussions.
