This is the eMeet USB Volume Controller eMute E1. It's a volume dial/knob device that connects to a PC via USB. It has a USB-C port and a detachable cable. It supports volume adjustment and one-click microphone muting, making it useful for remote work and online meetings at home. In music mode, you can pause and select previous/next tracks. It has a simple appearance, a matte texture, and a blue LED that looks good. With the standard driver, you can adjust the volume by rotating the dial. Customization is possible with the eMeetLink software. However, the eMute is not recognized in the latest version of eMeetLink. You can download V4.28 (Windows) from the WebArchive, and it will be recognized in this version. https://web.archive.org/web/20230324052331/https://emeet.com/pages/software-service-downloads At the time of listing, I confirmed the basic operation with the above eMeetLink V4.28. The item includes the main unit and a tested USB A to C cable only. The price has already been reduced, so please refrain from negotiating a lower price. Please note that returns are not accepted after the item has been shipped to prevent swapping.
