Mino X is one of the smallest floating Bluetooth speakers currently available. It features rubber casing in eight vibrant colours and IPX7-certified water resistance. When dropped into water, the speaker floats, which makes it ideal for use at a pool or in a bathroom. The speaker boasts three watts of power and a battery supporting three hours of playback. With Bluetooth 4.2 connectivity, it can also be used for hands-free calls and as a remote control for taking selfies.
