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.
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.
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.
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.
Up to 24 hours of battery life means the SRS-XB33 can party even longer than you can. Even with the lighting on in EXTRA BASS™ mode, you can party for up to 14 hours.
Developed by Sony, the X-Balanced Speaker Unit achieves high sound quality and powerful sound pressure for a richer, deeper, more rewarding listening experience.
The rigid and lightweight Mica Reinforced Cellular (MRC) speaker cone and dust cap contribute to the sound quality.
Unlike the circular diaphragm in a conventional speaker unit, the newly developed X-Balanced Speaker Unit in the XB33 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.
The layout of the side passive radiators has been optimized to reproduce clear bass sound.
The speakers of the SRS-XB33 are carefully designed to give you a real three-dimensional experience. Our angled speakers with DSP technology send your music to a wider area, creating a festival vibe, wherever you are.
Hit the LIVE SOUND button and hear your music in a whole new way. Bring your party to life with a unique three-dimensional sound experience — creating festival vibes wherever you go.
There's no fun without party lights. The SRS-XB33 features a speaker light and a multi-color line light that flash in sync with the beat. You can even change the color of the line light to suit your mood.
Control the party from the dancefloor, with the Sony | Music Center app—select your favorite playlists, cue the next song, or change sound modes.
Enjoy the same song, multiplied, with Party Connect. Connect up to 100 compatible 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.
The speakerphone function offers a convenient way to talk hands-free, whether it's a conference call for work or a chat with friends.
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.
Whether you place it horizontally or vertically the SRS-XB33 sits securely so you can always find space for it, wherever you're partying.
