This is the receiver you use to turn on the bluetooth on your old school wired speaker. It's a really simple process and it works great. This not only makes them Bluetooth but also adds 3D audio to them which sounds amazing I have to say. I love that this receiver automatically reconnects to the last device as soon as you turn it on. Of course, if you want a new device, you'll have to unplug it and fix it, but it's very easy to do.
