Tough enough for any adventure and powerful enough for any music, the Sony SRS-ULT10B is your ever-ready travel companion.

Powerful sound, packed in your bag
With decades of audio experience, who better than Sony to trust with your music on the move. The Sony SRS-ULT10B produces deep, powerful sound from a robust Bluetooth speaker that punches harder than you’d expect from such a compact design.

Extra bass, at the touch of a button
For the times when the music calls for that little bit extra, push the ULT button and unlock an extra layer of bass presence. With enhanced sound pressure, the boosted bass delivers a deeper, richer sound at the touch of a button. If the speaker is out of reach, you can also select the ULT setting via the Sony Music Centre app.

Waterproof, washable and dustproof for durability
Meeting IP67 standards for dust and waterproofing, the SRS-ULT10B can withstand being dropped in the bath/pool or a sudden downpour at your BBQ. You can even wash it down after a muddy festival. The dustproof construction also makes it ideal for music at the beach or workshop.

Shockproof design
Having undergone extensive testing, the SRS-ULT10B is designed to withstand the knocks and bumps that come with being a portable device. The shockproof casing has rounded edges, making it less likely to mark or damage the rest of your bag’s contents, too.

Always to hand
Weighing just 0.7kg and about the size of a medium water bottle, the SRS-ULT10B fits almost any bag. The non-slip surface makes it easy to pick up, even with wet or muddy hands. Supplied with an adjustable strap, you can carry it handsfree, or hang it up in a convenient location.

Enjoy sound anywhere
Thanks to a built-in rechargeable battery, you can take the Sony wherever you fancy. The 12-hour battery life makes it perfect for a camping trip, weekend festival or a couple of sunny days in the garden.

Hands-free call compatible with built-in microphone and Echo Cancelling
With its built-in microphone, this Bluetooth speaker also works as a hands-free speaker for your smartphone. When a call comes in the music is muted, letting you take the call in comfort. Echo Cancelling allows two people to talk at the same time, without cutting either of them off.

Quick and easy to pair
With Bluetooth pairing, it’s easy to link up to almost any smartphone, tablet or laptop device. Fast Pair cuts the connection time when using an Android device, making it even easier to get the music flowing with your friends. Connect two SRS-ULT10B speakers via Bluetooth, choose Stereo mode and enjoy an even more immersive sound. With two speakers, you not only get higher volume but also stereo sound for lifelike staging.

Take control with Sony’s Music Center app
Available for iOS and Android, the Sony Music Centre app gives you full control of the speaker from your smartphone or tablet. Select your favourite playlist, cue the next song or change the sound modes.

Pack a punch, with the Sony SRS-ULT10B.
