Harman, the maker of Harman/Kardon and JBL audio equipment, has launched a compact stereo music system aimed at mobile audiophiles. The JBL On Tour iBT is a portable two-channel all-in-one system that connects to iPhones, iPads, and iPods, as well as most other tablets and smartphones, using Bluetooth. The circular unit is relatively small at 6.5 inches diameter and just over 1.6 inches thick.
