How LIVE SOUND mode works
The speakers of the SRS-XB21 are carefully designed to give you a real three-dimensional experience. The blue lines show how angled speakers with new DSP technology send your music to a wider area, creating a festival vibe, wherever you are.

Small on size, big on fun
The compact SRS-XB21 fits easily in your bag. You can even pop it in the cupholder of your bike - so the party goes wherever you go.

Mica reinforced speaker
Made with Mica Reinforced Cellular (MRC), the rigid and lightweight speaker cone effortlessly controls the sound without losing quality, by driving power directly into the air.

Light up the party
There’s no fun without party lights, and the SRS-XB21 has just the thing - flashing new line lights that sync to the beat of your favourite tracks.

Dual 42mm speaker units
A 42mm speaker means powerful sound and bass.
