This is the travel-worthy speaker system that provides optimized, high-fidelity sound from any wireless source. When paired with a smartphone, tablet, or other wireless device, the Bluetooth speaker's digital signal processor analyzes the incoming signal and employs a patented algorithm to achieve the highest audio resolution possible. As a result, the 2 1/2-inch, 6-watt woofer, and the two 3-watt tweeters deliver ambient sound with a richness that belies their size. The speaker unfolds from a leather-covered hard-sided case that serves as its stand, delivering robust audio anywhere a traveler desires. It also acts as a travel alarm clock, and an extendable antenna allows it to receive FM radio signals. A 3.5mm line input lets you connect the speaker to a non-wireless source. Rechargeable Li-Ion battery provides five hours of run time from a six-hour charge. Includes drawstring travel bag. 4" H x 6" W x 5" D. (7 lbs.)
