Item number MP6FH

The Sony SRS-XB31 Portable Wireless Waterproof Speaker gives you a light show and powerful bass.

Maximise the fun and amaze your ears with a three-dimensional sound experience created by new DSP technology that sends your music to a wider area to create a party vibe that's perfect for sharing.

Dual 48mm speaker units provide powerful sound and you can also boost your party anthems with the Extra Bass function that will really get the dance floor moving. Just stream songs, radio stations and podcasts wirelessly from your phone or tablet – it couldn't be easier.

Get hands on for DJ effects! Simply tap your speaker in different places to make different sounds - including scratch, snare, kick drum and cowbell. Control the volume with force, tap gently for a soft sound or give it a good hit for a loud output.

We also love the awesome light effects that add atmosphere and complement your music. From a soft glow to a flashing strobe, it adds the ultimate party vibes.

You get an outstanding battery life of up to 24 hours, and if your phone starts running low on juice you can charge it straight off the speaker.

The Sony SRS-XB31 is a tough, little cookie too, with waterproofing meaning it could even cope with being accidentally dropped in the pool or sea without a problem. The speaker cones are also reinforced, extending their life without losing sound quality.

Enjoy the same song with Wireless Party Chain, which gives you the option of connecting up to 100 wireless speakers via Bluetooth.
