Best answer: Absolutely. The Ultimate Ears Megaboom 3 can totally be used while in the pool, shower, or any other body of water. The speaker has an IP67, which means it's water-resistant and will even float around when placed in water. There is a slight catch though: it shouldn't be submerged for more than 30 minutes in more than one meter of water.Amazon: Ultimate Ears Megaboom ($180)
