Sony XB33 Extra Bass Portable Wireless Speaker - Black (SRSXB33/B)

Enjoy powerful sound anywhere

Enjoy deep, punchy sound wherever you like with your EXTRA BASS™2 speaker. Dual passive radiators work together with full-range speakers to enhance low-end tones, giving bass a boost.

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.

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-XB33 will keep on playing, no matter how dusty the surface

Built to last

The SRS-XB33 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-XB33 will keep on working.

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.

Side passive radiators

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

What is the X-Balanced Speaker Unit?

Unlike the circular diaphragm in a conventional speaker unit, the newly developed X-Balanced Speaker Unit in the XB33 features a non-circular diaphragm.

Increasing sound pressure and reducing distortion

The unit’s non-circular shape 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.

Greater clarity and a wider sound stage

In addition, the unit’s off-centre design and optimized weight balance help to enhance clarity and widen the sound stage.

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.

Stream music with BLUETOOTH® technology and NFC™

Near Field Communication (NFC) and Bluetooth® technology remove the need for wired connections and complex set-up sequences. Simply touch your NFC-enabled device to the speaker for a quick, seamless connection, then start streaming your music collection. No NFC? No problem. Connect via Bluetooth and you're ready to go.

USB Type-C® and USB charging ports

Use a USB Type-C® cable to charge the SRS-XB33 and if your smartphone’s running low on power, just plug it into the speaker’s USB port to charge up the battery.

Stand it upright or on its side

Whether you place it horizontally or vertically, the SRS-XB33 sits securely so you can always find space for it, wherever you’re partying.
