IP ratings refer to the rating of protection given by an enclosure, against solids and liquids. In the format of IPXX, 'X' represents a number The first value of the IP rating refers to protection against solids say dust, followed by the one that refers to resistance against liquids (sweat).
Scoring IPX4, the Sony WF 1000XM4's rating is read as, the first number of X denotes that no data available to specify a protection rating, and the second value of 4 means that they can withstand low pressure spray similar to that of a shower head when tilted at 180° for 10 minutes.

The Sony WF 1000XM4's lowest frequency is at 20Hz, low-frequency response measures if and how well an audio component generates low audible frequencies and if it makes any changes to the signal while at it. Sony WF 1000XM4's highest frequency is at 40,000Hz, high-frequency response indicates how well an audio component makes high human frequencies and if it makes any changes to the signal on its way through. The sound pressure level, is the pressure level of sound, 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. A device's battery life is usually given by the manufacturer, and with longer battery life, you get to use it for longer and requires fewer chargings.
