3. Wireless portable speakers are devices that play audio content from a source such as an mp3 player,smartphone, tablet, laptop or any Bluetooth enabled device. They are capable of projecting sound at high volume while using low power consumption. Many of these speakers are novel in their design and are available in a range of shapes, sizes and materials. Most incorporate a rechargeable power source.
