The Nyne AQUAGRY was built not only to withstand a hearty splash, but even to float safely on the water. Its rugged, rubber-coated body even looks like an outrigger boat. This Bluetooth speaker pairs wirelessly with any compatible smartphone or portable music player. Keep your phone safe on dry land and take your tunes with you when you go into the water. Just tap the dedicated "answer" button on top of the speaker one time to talk hands-free. Or tap it twice to send the call to your voicemail, so you can keep lounging. There are also built-in controls for volume and power, plus an EQ button that lets you cycle through four presets to adjust the sound to your liking. The built-in rechargeable battery gives you up to 10 hours of wireless music on a single charge.
