Ingress protection ratings is the level of protection given by a casing, against solids and liquids. In the format of IPXX, 'X' represents a number The first value represents protection against solids say dust, while the second refers to resistance against liquids (sweat).
Having a value of IPX4, the JBL Tune Flex's rating for solids indicates that no data available to specify a protection rating, and the second value of 4 means that they can withstand low pressure spray similar to that of a shower head when tilted at 180° for 10 minutes.
