The Sony WF 1000XM4's highest frequency is at 40,000Hz, high-frequency response measures if and how well a particular audio component produces high recognizable frequencies and if it makes any changes to the signal on its way through. The sound pressure level, is the level of pressure of sound, measured in decibels, dB, Sony WF 1000XM4's measurement is 105dB/mW.
Devices with a higher sound pressure level are generally louder when supplied with any given audio source. The Sony WF 1000XM4's battery life is 8 hours, these last longer than 5 hours of listening which is considered average for a single charge.
