Sony SRSXB23i EXTRA BASS Bluetooth Wireless Portable Speaker (Blue)

Go anywhere with full, crisp sound in a lightweight, stylish design. The XB23 is IP67 waterproof, rustproof, dustproof and shockproof, with up to 12 hours of battery life, so your music never gets left behind. Keep the good times going with super-efficient USB-C charging, and control sound settings with the Sony | Music Center app.

Play It Loud with EXTRA BASS

Turn up the volume and hear the clarity of EXTRA BASS. Dual passive radiators work together with full-range speakers to enhance low-end tones, giving bass a boost.

Waterproof and Rustproof

With an IP67 rating, your speaker is waterproof – so you’ve got no worries using it by the sea or the pool – and there’s no problem washing it either.

Dustproof for Outdoor Activities

With an IP67 rating, you can take your speaker to the trail, the forest, the city, or wherever you like - the XB23 will keep on playing, no matter how dusty the surface

Shockproof, Built to Last

The XB23 has undergone extensive shock testing to make sure it can withstand the inevitable knocks, bumps and scrapes that come with everyday use.

Battery Life to Outlast The Party

Up to 12-hour battery life means the XB23 can party even longer than you can.1 Even in EXTRA BASS mode, you can party for up to 10 hours. The convenient battery button lets you know when it’s time to recharge.

Handy, Super-Portable Design

Compact and lightweight, the XB23 fits perfectly in the cupholder of your camping chair – great for the park, the beach, or the mountains. And the convenient strap lets you hang your speaker in your tent or on the nearest tree – wherever you want to share your favorite beats.

Get Things Booming with Party ConnectConnect

Enjoy the same song, multiplied, with Party Connect.6 Connect up to 100 wireless speakers with BLUETOOTH technology and the music and lights sync-up so everyone dances to the same beat. Set a random pattern or set the lights to blink in a circle.

X-Balanced Speaker Unit Enhances Sound Quality and Power

Developed by Sony, the X-Balanced Speaker Unit achieves high sound quality and powerful sound pressure for a richer, deeper, more rewarding listening experience.

How the X-Balanced Speaker Unit Works

Unlike the circular diaphragm in a conventional speaker unit, the newly developed X-Balanced Speaker Unit in the XB23 features a non-circular diaphragm. This not only maximizes the area of speaker diaphragm, increasing sound pressure for more punchy bass – it also reduces driver excursion while maintaining the same sound pressure, resulting in less distortion. Meanwhile, the unit’s off-center design and optimized weight balance help to enhance clarity and widen the sound stage.

USB Type-C Port

Use a USB Type-C cable to charge the XB23.

Convenient Hands-Free Calling

The speakerphone function offers a convenient way to talk hands-free, whether it’s a conference call for work or a chat with friends.

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 sound modes.

Stand It On Its Side

Wherever and however you want to place the XB23 - horizontal or vertical - it will sit securely, making it perfect for small spaces.

Stream Music with BLUETOOTH Technology

Simply connect your smartphone to the XB23 via Bluetooth to start streaming all your favorite music

Side Passive Radiators

The layout of the side passive radiators has been optimized to reproduce clear bass sound.
