Lenco BT-4304 3D Sonic Emotion Speaker (Bluetooth, 80 watts) for Smartphone and Tablet Black (Personal Computers)
Sonically I have long heard nothing so bad, and the Bluetooth connection, even at about 3 m (without Hinternisse) permanent dropouts! Those looking for something, which I can Onkyo RBX-500 (B) iLunar recommend 3D Dock, is only slightly more expensive
