The Harman Kardon One is a beautifully designed portable Bluetooth speaker that'll look great and sound better, wherever you put it. Bluetooth technology means that your phone or tablet will connect wirelessly to the speaker, so you and your phone are not tethered to it by cables. (If your device does not have Bluetooth capabilities, simply use a 3.5mm audio cable to connect to the speaker.) Once connected, the Harman Kardon One streams crystal clear, high quality audio that you can take with you wherever you go. It also features HTC Connect technology that makes paring with HTC devices even easier. Aside from its music-playing function, the Harman Kardon One also lets you take hands-free calls with the touch of a button.
