This portable Bluetooth wireless speaker makes it easy to enjoy high-quality music playback – or set up a speakerphone – wherever you are. Measuring 10.6" W x 4.1" H x 4.5" D, the speaker is equipped with two 3" full-range drivers and a passive radiator to deliver clear, powerful audio with enhanced bass. The durable housing is outfitted with an elegant fabric grille. Power, play/pause, volume and hands-free calling buttons are located on the top of the speaker for easy access, with the built-in mic (for making calls via a paired smartphone) conveniently located on the front of the speaker next to the power LED. A 3.5 mm (1/8") jack is available on the back of the speaker, allowing you to listen to audio from a wired device. The speaker's internal battery supplies up to 12 hours of continuous playback, and can be recharged using the included 1 m (3.3') USB charging cable. The speaker also comes with a 0.6 m (2') audio cable, terminated with 3.5 mm (1/8") mini-plugs, to enable wired connection.
