The Uwater K7 won’t shrink in water and that’s a good thing, because it is about as small as could be already. The world’s smallest 100 percent waterproof FM radio/receiver will be showcased at next month’s Consumer Electronics Show, and is provides music, news, sports and talk radio to swimmers.
The device has a built-in Li-Ion rechargeable battery, which juices up from a USB port, and it can run for eight hours on a single charge.
It features a one-inch LCD screen, 19 station preset, stereo sound, indoor/outdoor reception (even under water) and “twist & lock” earphones are included. The silicon ear tips even come in two sizes, and at just an ounce this one won’t hold you back in the water.
