Hands-free with built-in mic let's you enjoy phone calls even when you're busy with your outdoor activities Water Resistance: IPX6 Water Resistant This makes Apollo a great poolside companion, but keep in mind: At the back of the speaker there is a small rubber cover protecting the charging port, USB connector, and audio input connector The rated water resistance level is only possible when that small cover is firmly attached to the speaker Therefore, when your charger, or USB drive, or 3.5mm (1/8") audio jack are plugged in it's best to keep your Apollo somewhere where it won't get soaked with water In other words, splashing your Apollo in water while the protective rubber cover is off for whatever reason will leave your speaker vulnerable to water damage
