Get to know this product.

Enjoy powerful sound anywhere

Enjoy deep, punchy sound wherever you like with your EXTRA BASS™ speaker. Dual passive radiators work together with full-range speakers to enhance low-end tones, giving bass a boost.

Handy, super-portable design

Compact and lightweight, the SRS-XB23 fits perfectly in the cupholder of your camping chair—great for chilling out at open-air festivals. 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.

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.

Side passive radiators

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

Mica Reinforced Cellular speaker cone and dust cap

The rigid and lightweight Mica Reinforced Cellular (MRC) speaker cone and dust cap contribute to the sound quality.

Totally dustproof

Thanks to the IP67 rating, you can take your speaker to the beach, the forest, the desert, or wherever you like—the SRS-XB23 will keep on playing, no matter how dusty the surface.

Totally washable and waterproof

With an IP67 rating, your speaker is waterproof and salt water resistant—so you've no worries using it by the sea or the pool—and there's no problem washing it either.

Built to last

The SRS-XB23 has undergone extensive shock testing to make sure it can withstand the inevitable knocks, bumps and scrapes that come with everyday use. Even if you drop it, the SRS-XB23 will keep on working.

Long battery life

Up to 12 hours of battery life means the SRS-XB23 can party even longer than you can. Even in EXTRA BASS™ mode, you can party for up to 10 hours.

Speakerphone for hands-free calls

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