The GoodThe Rocketfish Mobile SPX15 is a very compact Bluetooth speaker that has a built-in rechargeable battery, a line input, and speakerphone capabilities. It plays relatively loud for its tiny size.
The BadIt could cost a little less; it can't handle big bass at higher volumes; and it sounds a little thin.

Then you look for SPX15 on your Bluetooth-enabled phone or tablet from within the Bluetooth menu. Once it connects, you're ready to start streaming music or a movie soundtrack to the speaker.
