Sound worth sharing The SRS-XB43 wireless speaker blends deep, punchy bass with clear vocals for that signature festival sound. It's durable and easy to use, too, so you and your friends can focus on enjoying the party.

Discover the SRS-XB43 Explore some of the features and technologies that make the SRS-XB43 so special.

Sound 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.

Durability The SRS-XB43 has been engineered to deliver an irresistible blend of deep, resonant bass and clear, natural vocals.

Usability Developed by Sony, the X-Balanced Speaker Unit achieves high sound quality and powerful sound pressure for a richer, deeper, more rewarding listening experience.

Enjoy powerful sound anywhere 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.

Sound 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.

X-Balanced Speaker Unit 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.

What is the X-Balanced Speaker Unit" 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.

What does it do" 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.

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

Tweeter improves vocal clarity 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.

Mica Reinforced Cellular speaker cone and dust cap 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.

Side passive radiators 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 .

Hear it like it's live 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

Electronics can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new electronics should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.
