The JBL Boombox 2 has a contemporary design, defined in particular by the convex underside, which flows into a slender base. Together with the iconic handle, this lends the speaker a distinctive aura. The device delivers sound with punchy bass notes, a clear mid range and smooth treble tones, so it can pump out ample sound even for a party. The battery lasts up to 24 hours, and the boom box is also capable of charging other devices.
