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 cup holder of your bike—so the party goes wherever you go.
Dual 42 mm speaker units
A 42 mm speaker means powerful sound and bass.
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.
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. 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 favourite playlists, cue the next song and change lighting patterns and sound modes.
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.
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.
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 hours battery means that the SRS-XB21 can party even longer than you can.
Wireless with BLUETOOTH® technology and NFC™
BLUETOOTH® streaming with NFC™ connectivity makes it simple to stream your party playlist.
Easy button control
No need to rely on a device to operate your SRS-XB21. Do everything you need with just the buttons on your speaker.
