You already have the maximum available quantity in your cart.
The SayoDevice E1 USB volume control knob is a small desktop accessory that allows you to adjust your computer's volume by smoothly turning the knob instead of searching for the speaker icon on the screen or using key combinations. The knob rotates a full 360 degrees and you can quickly mute the sound with a press from the top. The controller connects to your computer via a cable and functions as a standard input device. You can adjust the volume while gaming, watching films, listening to music, or during video calls. Thanks to its compact size, the controller fits next to your keyboard, mouse, or monitor and takes up minimal space on your desk. On the side of the controller is a USB-C port, allowing you to detach the cable for easy storage or transport to another computer.
The controller requires no software installation. Simply plug it into a free USB port and the system will recognise it automatically, enabling you to use it within seconds. According to the seller, it is compatible with operating systems Windows 10, 8, and 7, with Mac computers, and with devices running Android. In addition to volume control and mute, the controller also supports skipping tracks forward and backward, and you can customise the button functions with your own keyboard shortcuts. At the bottom of the body is a translucent ring with colourful RGB backlighting, which looks modern on your desk and helps you locate the controller even in low light. The backlighting can shine in several different colours.

Place the controller on a flat surface near your keyboard, where it is easily accessible. The anti-slip pads on the bottom keep the controller in place, preventing it from moving while you turn the knob. The long cable allows you to position the controller further from the computer, for example, on the other side of the desk. Simply wipe the surface occasionally with a dry or slightly damp cloth; do not use aggressive cleaning agents or allow water to enter the controller.
The SayoDevice E1 USB volume control knob is a practical addition for home offices, gaming setups, video editing, and music playback at events. You control the volume with a natural hand movement, and mute is always at your fingertips. Its compact body with a diameter of 5 cm fits on any desk, and the detachable cable makes it easy to transport. The colourful backlighting adds a pleasant look to your desk. You will appreciate the controller wherever you want to keep sound under control with a single motion.
