Ingress protection ratings refer to the rank of protection offered by an enclosure, against dust and water. The letters 'IP' are followed by two values The first value of the IP rating represents protection against solids such as dust, while the second 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 of liquids that they can withstand low pressure spray similar to that of a shower head when tilted at 180° for 10 minutes. JBL Tune Flex have a weight of 9.6g . We take in account a lower weight better for the reason that lighter devices are easier to transport.

JBL Tune Flex have stereo speakers, what this means is that JBL Tune Flex's speakers deliver sound from independent channels on both left and right sides, creating a richer sound and a better listening experience. Active noise cancellation utilises more advanced technology to actively counter noise.
How it works, it studies the sound pattern of incoming noise and inverts the soundwaves to counter it. Simply put, it's like having +1 (noise) then adding -1 (inverted noise) giving 0 which results in a reduced level of noise.

The JBL Tune Flex's lowest frequency is at 20Hz, low-frequency response measures if and how well an audio device generates low frequencies that can be heard, and if it alters the signal on its way through.
The JBL Tune Flex's highest frequency is at 20,000Hz, high-frequency response tells how well an audio device makes high recognizable frequencies and if it makes any changes to the signal on its way through. 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.
The JBL Tune Flex's battery life is 8 hours, these last longer than 5 hours of listening which is considered average before recharge.
