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 and create 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 the 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.
Sound that takes your party to the next level
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, and 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.
Long battery life
Up to 12 hours of battery means the SRS-XB21 can party even longer than you can. Even with the EXTRA BASS mode on, you can party up to 10 hours.
1.2 m shock proof
The system passes the drop test from 1.22m on plywood of 5cm thickness conforming to MIL-STD 810 F Method 516.5-Shock.
