Boost your party anthems with EXTRA BASS™️
Enhance every beat and give your party that extra boost thanks to EXTRA BASS™️.
Sound that takes your party to the next level
Light up the party
There’s no fun without party lights. The SRS-XB31 has multi-coloured flashing lights that sync to the beat, including new line lights and a flashing strobe.
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 favourite 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.
Long battery life
Up to 24 hour battery means the SRS-XB31 can party even longer than you can. Even with the EXTRA BASS mode on, you can party for up to 14 hours.
1.2m 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.
