105dB/mW
JBL Live Free 2 102dB/mW
The sound pressure level, is the level of pressure of sound, measured in decibels, dB, JBL Live Free 2's measurement is 102dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
Sony WF 1000XM4's sound pressure level measurement is 105dB/mW. How loud a device is can be taken differently by different people, so we need to have a way of getting a standard measurement of sound level expressed in numerical terms.
