This little Lyrix PowerBall Bluetooth Speaker looks like a cut gemstone, but it’s a great little travel speaker. Pop off the top, and you reveal a Bluetooth 3.0 with AVRCP and A2DP-support, 3W speaker with a “sealed chamber, passive radiator design with neodymium” design; it reproduces 40Hz-20kHz (-10dB). It has a lithium-ion battery good for 12 hours of music, and it has a 3.5mm audio-in jack so you can use non-Bluetooth music sources with it, too. It’s available in blue, green, pink, black, purple, or red for $49.95 at Digital Treasures.
