FAQs & How-Tos
My device is waterproof, but what about salt water or chlorine water?
Your JBL speaker is waterproof with IPX7 rating. (IPX7 means it can survive immersion in 1 meter/3.3 feet for up to 30 minutes.) To maintain the looks and functions of your speaker, please make sure to rinse it with fresh water after using it at a swimming pool or the ocean, then dry off all covers and areas where water can gather. The standard for waterproofing is for tap water. Chemicals and salt in your pool or the ocean can damage the waterproof seals or harm the surface finish over time if not rinsed off after use.

IP67 InformationThis product is rated IPX67 which is different from IPX7. IP67 protects the product from submersion in 1 meter (3.3 feet) of water for up to 30 minutes, but it is also resistant against dust. Dust accumulation around electronics can lead to hardware failure so the IP67 rating is extremely beneficial addition to this product.

Issues with the JBL Portable App and your Android device
