Ingress protection ratings refer to the level of protection given by a casing, against dust and liquids. 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 protection against liquids (water).
Having a value of IPX4, the JBL Tune Flex's rating is read as, the first number of X denotes that no data available to specify a protection rating, and of liquids that they can withstand low pressure spray similar to that of a shower head when tilted at 180° for 10 minutes.

A driver unit is the component that produces sound in the earbuds, its size determines the sound made by the earbuds. The JBL Tune Flex's lowest frequency is at 20Hz, low-frequency response measures if and how well a particular audio component produces low audible frequencies and if it makes any changes to the signal while at it.
JBL Tune Flex's highest frequency is at 20,000Hz, high-frequency response measures if and how well an audio component generates high recognizable frequencies and if it makes any changes to the signal while at it. The sound pressure level, is the pressure level of sound, measured in decibels, dB, JBL Tune Flex's measurement is 108dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
JBL Tune Flex's battery life is 8 hours, these last longer than 5 hours of listening which is considered average for a single charge.
