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.
