which means that they have a smaller driver unit than that of JBL Tune Flex by 5.2mm
, many people have a misconception that driver units of a bigger size automatically produce better sound quality.
However, large drivers usually have difficulty producing high frequencies so it's true that, larger drivers are capable of generating louder sound, but this does not indicate that they deliver better quality sound. The JBL Tune Flex's lowest frequency is at 20Hz, low-frequency response measures if and how well an audio component produces low frequencies that can be heard, and if it alters the signal while at it. JBL Reflect Aero TWS's lowest frequency is at 20Hz, this implies that
both devices can produce equal bass
The JBL Tune Flex's highest frequency is at 20,000Hz, high-frequency response measures if and how well an audio device produces high recognizable frequencies and if it changes to the signal while at it.
JBL Reflect Aero TWS's highest frequency is at 20,000Hz, this means that
both devices can produce equal treble
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 Reflect Aero TWS's sound pressure level measurement is 99dB/mW.
The sound pressure level, something is can be perceived differently by different people, so we need to have the means to get a standard measurement of sound level expressed in numerical terms.
