Enjoy Superior Sound Wherever and Whenever with Sony’s Latest EXTRA BASS™ Wireless Speakers

Sony today refreshed its EXTRA BASSTM wireless speaker line-up with the addition of the SRS-XB43, SRS-XB33 and SRS-XB23. With superb sound quality, toughness and usability at the forefront of the latest designs, you can enjoy superior sound wherever and whenever.

Sound worth sharing

EXTRA BASSTM Sound Enjoy deep, punchy bass wherever you are with these latest wireless speakers. EXTRA BASSTM sound is achieved on the XB wireless speaker line up thanks to Sony’s renowned audio technology detailed below.
X-Balance Speaker Unit Sony’s newly developed X-Balanced Speaker Unit achieves high sound quality and powerful sound pressure for a richer, deeper and more rewarding listening experience. The unit’s non-circular shape maximises the area of the speaker diaphragm, increasing sound pressure for more punchy bass. It also reduces driver excursion while maintaining the same sound pressure, resulting in less distortion. For example, the level of the sound pressure on the XB33 has increased by approx. 30% and distortion rate is reduced by approx. 25% compared to the predecessor model (SRS-XB32).




Unlike the circular diaphragm in a conventional speaker unit, the X-Balanced Speaker Unit in the XB43 features an almost rectangular diaphragm. Its 2-way speaker system combines a woofer for low to mid frequencies with a dedicated tweeter for the higher range frequencies. The result is powerful sound, deep punchy bass and exceptional vocal clarity.






The X-Balanced speaker unit in the XB33 and XB23 features a newly developed noncircular diaphragm and off-centre design. This new design maximises the speaker diaphragm, creating more sound pressure, but keeps the speakers compact in size.


Mica Reinforced cellular (MRC) cone and dust cap

The rigid and lightweight MRC cone and dust cap contributes to the sound quality.

Side Passive radiators

The layout of the side passive radiators has also been optimised across all three models to reproduce clear bass sound.


LIVE SOUND mode brings your party to life with a 3-dimensional sound experience as if you were at a live venue.

Do more, worry less
Waterproof, dust proof and rust proof

The new models have an IP67 rating, so you can take your speaker to the beach, the forest, the desert or wherever you like – it will carry on playing no matter how dusty the surface. The speakers are even saltwater resistant so the fun can continue even in the sea!


The speakers have undergone extensive shock testing and thanks to the latest shock-proof durable design, can withstand the inevitable knocks, bumps and scrapes that come with everyday use. Now even the clumsiest of accidents are no longer an issue, even if you drop them, the speakers will keep working6.
