IP ratings refer to the level of protection offered by a casing, against solids and water. The letters 'IP' are followed by two values The first value of the IP rating means protection against solids say dust, followed by the one that refers to protection 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.

The JBL Tune Flex's lowest frequency is at 20Hz, low-frequency response inidcates how well an audio component generates low recognizable frequencies and if it alters the signal on its way through. JBL Tune Flex's highest frequency is at 20,000Hz, high-frequency response indicates how well an audio device produces high audible frequencies and if it changes to the signal while at it. The sound pressure level, is the pressure level of sound, 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 before recharge.

JBL Tune Flex have a noise-canceling type of microphone, these microphones are intended to filter out background sounds from the earbuds' sound. The JBL Tune Flex microphone sensitivity is measured at -38dBV/Pa. The vastness of the analog or digital output signal from the microphone with its input stimulus is a calculation of its sensitivity.
It's the 'loudness' of the sound that the microphone can pick up. The JBL Tune Flex support ambient sound mode, which uses microphones to pass through ambient sound so that they can still be heard even when wearing the earbuds
