The Konftel Ego is designed for meetings with up to four participants. In spite of its small dimensions, the sturdy and handy device provides good 360-degree surround sound. Distortion is prevented by the use of special OmniSound technology. A small, intuitively understandable display is located under the etched metal cover. Call and music modes are controlled by buttons at the side, and there is a headset and a USB port as well as support for Bluetooth and NFC.
