There are plenty of portable speakers on the market, but how many of them can claim ultra-portability? The JBL Go 4 certainly can. It's a compact Bluetooth speaker designed to be taken anywhere. It offers an IP67 rating, so it is both dustproof and waterproof. But it also sounds great despite its small size, with a punchy bass and clear sound. You can even daisy chain the speakers if you feel like buying a whole fleet, allowing you to combine them for bigger sound.
