Sony SRS-XB31 Portable Bluetooth Speaker (Black)

Enjoy the ultimate three-dimensional music experience on the go with the Sony XB31 Wireless Bluetooth Speaker. Thanks to the Extra Bass and Live Sound, Party Booster features, this portable speaker is definitely going to boost up your party spirit with flashing lights that match the beat. The Sony XB31 comes with an IP67-rated waterproof design with up to 24-hour battery life.

Festival Vibe and Sound

Enhance every beat and give your party that extra boost with Extra Bass feature or hit the Live Sound button and hear your music in a whole new way. The 48mm drivers of the XB31 are carefully designed to give you a real three-dimensional listening experience. These drivers are placed at an angled position and use DSP technology to produce a powerful sound that reaches to a wider area. The lightweight driver cone, made with Mica Reinforced Cellular (MRC), offers a large displacement edge that ensures you get an amazing sound quality.

Featuring a built-in grip that makes it easier to hold, you can tap your speaker in different places to make different sounds - like a scratch, snare, kick drum and cowbell. Control the volume with a change in force; tap gently for a soft sound or give it a good hit for a loud output.

Sony | Music Center App
