Review on Portable Bluetooth Speakers Subwoofer Wireless Home Audio by Karen Turner

I use it as a speaker for a chess computer (DGT Pi) and it works great. That's exactly what I wanted. The DGT Pi is already powered from the socket and has a speaker/headphone output. All I have to do is plug this speaker into the DGT Pi's USB and audio jacks and I'm good to go. The speaker does not need to be connected to the wall. Off topic, but it seems strange that they didn't even bother to put the cheapest, simplest little speaker cone in this DGT Pi chess computer. Having to put on headphones every time you want to play chess seems crazy. Either way, this speaker is well priced and makes up for a DGT design flaw (one of many).
