Live music experience

Hear your music in a whole new way with LIVE SOUND mode. Bring your party to life with a unique three-dimensional sound experience - creating festival vibes wherever you go.

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 bottle-holder of your bike - so the party goes wherever you go.

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 favorite tracks.

Give your party an extra boost with Party Booster

Simply tap your speaker in different places to make different sounds—like a scratch, snare, kick drum and cowbell. Control the volume with force, tap gently for a soft sound or give it a good hit for a loud output.

Get things booming with Wireless Party Chain

Enjoy the same song with Wireless Party Chain. Connect up to 100 wireless speakers with BLUETOOTH® technology and the music and lights sync-up so everyone dances to the same beat.

Control the party with the Sony | Music Center app

Control the party from the dancefloor, with the Sony | Music Center app - select your favorite playlists, cue the next song, change lighting patterns and sound modes.

Ready for the pool and the beach

A new fabric design, not only looks good, but is tough enough to take whatever you throw at it.

Totally rustproof

Your SRS-XB21 is uniquely rustproof, so not only does it look good, but you can also enjoy your product near the beach, but a little sea water will not rust the product.

Totally waterproof

With an IP67 rating, your speaker can be immersed in water, and thanks to the high-quality fabric made exclusively in Japan, there'll be no problem rinsing it.

Totally dustproof

Thanks to the IP67 rating, you can take your speaker to the beach, the forest, the desert, or wherever you like—the SRS-XB21 will keep on playing, no matter how dusty the surface.

Lasts all day long

Up to 12 hour battery means the SRS-XB21 can party even longer than you can.
