Bose has launched the SoundLink Wireless Mobile Bluetooth speaker.

The portable device can connect wirelessly to any Bluetooth-enabled device, including smart phones, tablets and laptops, using A2DP Bluetooth 2.1.

It promises up to eight hours of playback from the rechargeable battery, and comes with a 3.5mm analogue jack input for non-Bluetooth devices.

The speaker includes four midrange/treble speakers with a pair of passive radiators and measures just 5cm thick – about the size of a hardback book.

A folding iPad 2-style cover can be used as a stand and automatically turns the speaker off when it’s closed over the front of the speaker.

The standard version comes with a dark grey Cordura nylon cover and costs £259. There’s also an LX model which has a premium trim around the speaker and a dark brown leather cover for £299.

Different coloured covers are also available, with bright red or royal purple nylon for £25, or burgundy or tan leather for £50.
