Sanwa Supply PC USB with Passive Radiator and Metal Mesh Speaker, Powered, Bass-Enhancing Panel, MM-SPL22UBK

This is a USB-powered speaker that draws power from a USB port. Since it does not require an AC power source, wiring is neat and tidy, making installation easy. The audio output is via a 3.5mm stereo mini jack, allowing you to enjoy audio by connecting it to a TV or other device in addition to a computer. The volume and power buttons are separate, so you don't have to readjust the volume. The speakers are angled upwards, making it easier for the sound to reach your ears and be heard. With a maximum practical output of 6W (3W + 3W), it is possible to reproduce clear sound.
