Cool, I love he bluetooth speaker. I've just finished converting an old pair of bluetooth headphones into a unit to stream music from my N900 to my car's stereo. So much better than paying $400+ for a kit to do the same thing from Pioneer! (sorry for the sort of shoddy photos, just finished it a few hours ago)

Back on topic, what have you done with the amplifier in the first post? Does it allow you to connect two speakers directly to your headphone jack and amplify the sound, instead it being fairly quiet?
