JBL Tune Flex's highest frequency is at 20,000Hz, high-frequency response shows how well an audio device generates high recognizable frequencies and if it makes any 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.
