Sony SRSXB43 EXTRA BASS Bluetooth Wireless Portable Speaker (Black)

Deep, resonant sound elevates your favorite music with the Sony SRSXB43 EXTRA BASS Bluetooth Wireless Portable Speaker. The newly-designed X-Balanced speaker unit gives the EXTRA BASS power of the Sony SRS-XB43 a crisper, fuller sound and two new tweeters for clearer vocals. The IP67 waterproof, rustproof and dustproof design means you can listen anywhere, indoors or out, with up to 24 hours of battery life.

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.

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.

How the X-Balanced Speaker Unit Works

Unlike the circular diaphragm in a conventional speaker unit, the X-Balanced Speaker Unit features an almost rectangular 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 and greater vocal clarity.

Tweeter Improves Vocal Clarity

The Sony SRS-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.

Side Passive Radiators

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

Waterproof and Rustproof

With an IP67 rating, your speaker can be immersed in water. Thanks to the high-quality fabric, there'll be no problem cleaning it too.

Dustproof for Outdoor Activities

With an IP67 rating, you can also take your speaker to the trail, the forest, the city, or wherever you like - the SRS-XB43 Portable Speaker will keep on playing, no matter how dusty the surface.

Lasts All Day Long

Up to 24-hour battery means this portable speaker can party even longer than you can. The convenient battery button lets you know when it’s time to recharge.

Lights Bring Your Music to Life

The SRS-XB43 Speaker features four speaker lights that accentuate the updated speaker construction, as well as line lights that go around the speaker to create just the right atmosphere. Amplify your party with a speaker light that syncs to the beat of your music.

Get Things Booming with Party Connect

Enjoy the same song, multiplied, with Party Connect. 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.

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.

USB Type-C and USB Charging Ports

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