Light Up the Party

There’s no fun at a party without party lights, so the XB21 has just the thing – new flashing line lights that sync to the beat of your favorite tracks. 

Wireless Party Chain

Let everyone 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.

BLUETOOTH® and NFC™ Technology

BLUETOOTH® streaming with NFC™ connectivity makes it simple to stream your party playlist.

Sony | Music Center App

Control the party from the dancefloor, with the Sony | Music Center app - select your favorite playlists, cue the next song, or change lighting patterns and sound modes.5 

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. 

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 a change in force; tap gently for a soft sound or give it a good hit for a loud output. 

Easy Button Control

No need to rely on a device to change the volume or skip tracks. Do everything you need with just the buttons on your speaker.

Totally Waterproof 

With an IP67 rating, the XB21 speaker can be immersed in water. Thanks to the high quality fabric made exclusively in Japan, there'll be no problem cleaning it.

Totally Dustproof 

With an IP67 rating, you can take your speaker to the trail, the forest, the city, or wherever you like - the XB21 will keep on playing, no matter how dusty the surface. 

Totally Rustproof

The XB21 is rustproof, so it won’t be subject to the elements – even salty air and water from the ocean. 


The compact 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. 

Battery Life

Up to 12 hour battery means the XB21 can supply music to even the longest events.
