4 In 4 Out USB 3.0 Sharing Switch Box with 3.5mm Audio Jack, One Button Switcher Allows 4 PCs to Share 4 USB Devices for Mouse Keyboard Scanner Printer, Plug and Play for Desktop and Laptop

This upgraded 4-in-4-out USB 3.0 sharing switch is a multifunctional centralized peripheral management device specially designed for multi-computer office environments, design workstations and home multi-host setups. It supports four different desktop or laptop computers to independently share four USB 3.0 peripheral devices at the same time, completely avoiding the tedious repeated plugging and unplugging of mice, keyboards, printers, scanners, flash drives and portable SSDs, and greatly organizes tangled desktop cables.

Different from ordinary USB switches, this model adds an independent 3.5mm stereo audio output interface. You can connect a headset or desktop speaker to this port, and synchronously switch the audio output source along with the computer host, which brings more convenient experience for online meetings, video conferences, music listening and voice calls without switching audio devices additionally.

Adopting standard USB 3.0 Gen1 transmission protocol, the maximum data transfer rate reaches 5Gbps, which is far more efficient than USB 2.0 switches when copying large-size design files, raw images and backup data, and effectively prevents transmission bottlenecks during scanner continuous scanning and printer batch document printing. The front panel is equipped with clearly marked physical push buttons corresponding to each host, users only need to press the matching button to complete instant host switching, with fast device recognition speed and no connection drop or delay.

The internal circuit is equipped with anti-electromagnetic interference shielding components, ensuring long-term continuous stable operation without signal distortion or port identification failure. It features true plug-and-play performance, compatible with Windows, macOS, Linux and other mainstream operating systems without installing extra control programs. The compact and sturdy housing saves valuable desk space, ideal for corporate administrative offices, graphic design studios, video editing workrooms, school computer classrooms and enthusiast multi-PC test platforms to improve overall work efficiency.
