Hi guys, Part of the moving sales, I'm selling a nice kit 2.1. The brand is Edifier. The speakers are quite powerful, and they have a USB port to plug a USB key on it. There is one problem though, the jack plug has a connection problem, which result in only one satellite working. Because the problem comes from the jack, both speaker work if using the USB connection. It should be a really easy fix. Anyway, because of this problem, I sell it really cheap: 50rmb.
