Bang & Olufsen's 'BeoSound A1' portable speaker is the perfect companion for impromptu outdoor gatherings with friends - it can connect to two devices at once, so there'll be no vying for the role of DJ. The robust aluminium and polymer case is waterproof and completely resistant to dust and sand, while the battery offers up to 18 hours of 'True360' omni-directional sound. It's also built with Bluetooth 5.1 and has three internal microphones that support voice calls and 'Alexa Voice Assistant'.
