Your own portable music festival
Throw the SRS-XB21 in your bag, grab your friends and start the party wherever you go. With EXTRA BASS™, live music sound and party lights it's the mini music festival that you can take with you.
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.
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 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 speakers2 with BLUETOOTH® technology and the music and lights sync-up so everyone dances to the same beat.
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.
Your SRS-XB21 is uniquely rustproof, so not only does it look good, but you can also drop it in the sea without a problem.
Totally washable3 and 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 washing 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
A 12 hour battery means the SRS-XB21 can party even longer than you can.5
