Overall Score 7.5 Represents average audio ecosystem compatibility score.
IP ratings is the rank of protection given by a casing, against dust and water. In the format of IPXX, 'X' represents a number The first value refers to protection against solids say dust, followed by the one that refers to resistance against liquids (water).
Scoring 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.

ANC works when, it detects and analyzes the sound pattern outside and inside the earbud and after inverts the soundwaves to cancel it out.

The JBL Tune Flex's lowest frequency is at 20Hz, low-frequency response measures if and how well a particular audio component generates low recognizable frequencies and if it alters 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 makes high audible frequencies and if it makes any changes to the signal on its way through.
The sound pressure level, is the level of pressure 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.
The JBL Tune Flex's battery life is 8 hours, these last longer than 5 hours of listening which is considered average before recharge. A device's battery life is commonly given by the manufacturer, and with longer battery life, you get to use it for longer and requires fewer chargings.
