Discover the SRS-XB43
Explore some of the features and technologies that make the SRS-XB43 so special.
Enjoy powerful sound anywhere
Enjoy deep, punchy sound wherever you like with your EXTRA BASS™ 2 speaker. Dual passive radiators work together with the two-way speaker system to enhance low-end tones, giving bass a boost.
The SRS-XB43 has been engineered to deliver an irresistible blend of deep, resonant bass and clear, natural vocals.
X-Balanced Speaker Unit
Developed by Sony, the X-Balanced Speaker Unit achieves high sound quality and powerful sound pressure for a richer, deeper, more rewarding listening experience.
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 XB43 features an almost rectangular diaphragm.
What does it do?
The unit's rectangular 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 and greater vocal clarity.
Maximizing sound quality
The X-Balanced Speaker Unit isn't the only reason the SRS-XB43 sounds so good—inside, you'll find a range of high-performance audio technologies.
Tweeter improves vocal clarity
The XB43's 2-way speaker system combines a woofer for low to mid-range frequencies with a dedicated tweeter for the higher range frequencies. The result is exceptional vocal clarity.
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.
Hear it like it’s live
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.
How LIVE SOUND mode works
The speakers of the SRS-XB43 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.
Totally dustproof, waterproof and washable
With an IP67 rating 3, you can take your speaker to the beach, the forest, the desert, or wherever you like—the SRS-XB43 will keep on playing, no matter how dusty the surface. It's waterproof and salt-water resistant too—so you've no worries using it by the sea or the pool—and there's no problem washing it either 4.
Long battery life
Up to 24 hours of battery life 5 means the SRS-XB43 can party even longer than you can. Even with the lighting on in EXTRA BASS™ mode, you can party for up to 14 hours.6
Light up the party
There's no fun without party lights. The SRS-XB43 has a tweeter light, a speaker light, and a multi-color line light that all flash in sync with the beat. You can even change the color of the line light to suit your mood.
Get things booming with Party Connect
Enjoy the same song, multiplied, with Party Connect. Connect up to 100 compatible wireless speakers 7 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. 8
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.
Download the Fiestable app and you'll be able to control the lighting on the SRS-XB43, and you can also use motion control gestures on your smartphone screen.

The SRS-XB43 has been designed with convenience in mind, so you can enjoy music when and where you want to, no fuss.
The speakerphone function offers a convenient way to talk hands-free, whether it's a conference call for work or a chat with friends.
Stand it up or on its side
Whether you place it horizontally or vertically the SRS-XB43 sits securely so you can always find space for it, wherever you're partying.
Stream music with BLUETOOTH® technology and NFC™
Near Field Communication (NFC) and Bluetooth® technology 9 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-XB43 and if your smartphone's running low on power, just plug it into the speaker's USB port to charge up the battery. An AC adapter is also included, enabling you to play music without worrying about battery life, and it offers another convenient way to charge your XB43, too.
