  • Boost your party playlist with EXTRA BASS™
    Enhance every beat and give your party that extra boost thanks to EXTRA BASS™.
  • How LIVE SOUND mode works
    The speakers of the XB21 are carefully designed to give you a real three-dimensional listening experience. Angled speakers with new DSP technology send your music to a wider area, creating a festival vibe, wherever you are.
  • 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.1
  • 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.
  • 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.
  • Battery life to outlast the party
    Up to 12 hour battery means the XB21 can supply music to even the longest events.2
  • Get things booming with Wireless Party Chain
    Let everyone enjoy the same song with Wireless Party Chain.3
  • Connect up to 100 wireless speakers with BLUETOOTH®
    technology and the music and lights sync-up so everyone dances to the same beat.4
  • Small on size, big on fun
    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.
  • 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 a change in force; tap gently for a soft sound or give it a good hit for a loud output.
  • Wireless with BLUETOOTH® technology and NFC™
    BLUETOOTH® streaming with NFC™ connectivity makes it simple to stream your party playlist.4
  • 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, 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.
  • Dual 42mm speaker units
    42mm speakers means powerful sound and bass.
  • 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.
