Enhance every beat and give your party that extra boost thanks to EXTRA BASS™. 

LIVE SOUND mode 

Hear your music in a whole new way with LIVE SOUND mode¹. Bring your party to life with a unique three-dimensional sound experience - creating festival vibes wherever you go.

How LIVE SOUND mode works

The speakers of the SRS-XB31 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.

Mica reinforced speaker

Made with Mica Reinforced Cellular (MRC), the rigid and lightweight speaker cone contributes to the sound quality.

Line Light

There’s no fun without party lights, and the SRS-XB31's new line lights go around the speaker. 

Give your party the 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.

Control the party with 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.

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.
