The JBL Tune Flex's lowest frequency is at 20Hz, low-frequency response inidcates how well an audio component produces low frequencies that can be heard, and if it makes any changes to the signal while at it.
The JBL Tune Flex's highest frequency is at 20,000Hz, high-frequency response measures if and how well an audio device makes high audible frequencies and if it adjustments to the signal while at it. The sound pressure level, is the level of pressure 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.
