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-colored 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 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.
Lasts all day long
Up to 24 hour battery means the SRS-XB31 can party even longer than you can.
