This is a new version control pod (black version) for Logitech z-2300 speakers. If your old control pod (silver version) is missing or broken, this is just what you need. It has the same functions of the original control pod. Thanks to redesigned PCB board and high quality shielded audio cables, the new version has improved performance compared to the old version. This is also compatible with Logitech z-2200s. You can simply connect this control pod to your subwoofer/speakers and your sound device (MP3, Computer, CD Player etc.) with the included cables.
