FUGOO Bluetooth speakers combine high-quality 360-degree audio with durability and 40 hours of battery life. One of the few speakers qualified for an IP67 rating, they are water, snow, sand, mud, dirt and dustproof, making them the speaker of choice for people who want to crank up the sound outdoors. The speakers are completely submersible in water up to one meter for 30 minutes. If they get dirty, no problem. Rinse them off with a hose. Optional accessories hook the speakers to a bike, boat, backpack or any pole nearby.
