Save you money for something better, unless you are buying for accident prone children.

Summary: It plays music, is powered through a USB on the PC, but if there's no music playing, there's a static feedback sound. It's not bad enough to send them back, but I wouldn't recommend them. They are also kind of on the quiet side.
Perfect - tiny size, great sound - no annoying LED glow

Summary: I got these to replace my Spekal iBoo, which was great but had an annoying blue light and a large foot print. I wanted something tiny, white to match my ikea desk surface, with a simple design, and without an LED, these are perfect.
