Ingress protection ratings refer to the rating of protection offered by an enclosure, against solids and water. The letters 'IP' are followed by two values The first value of the IP rating represents protection against solids say dust, followed by the one that refers to resistance against liquids (water).
Having a value of IPX4, the JBL Tune Flex's rating is read as, the first value of X denotes 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.

The JBL Tune Flex's highest frequency is at 20,000Hz, high-frequency response indicates how well an audio device generates high human frequencies and if it makes any adjustments to the signal on its way through. The sound pressure level, is the level of pressure of sound, measured in decibels, dB, JBL Tune Flex's measurement is 108dB/mW.
