IP ratings is the rating of protection given by a casing, against solids and water. The letters 'IP' are followed by two values The first value means protection against solids such as dust, followed by the one that refers to resistance against liquids (water).
Having a value of IPX4, the Sony WF 1000XM4's rating for solids indicates that no data available to specify a protection rating, and the second number 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 driver unit is the component that makes sound in the earbuds, the unit size corellates with the sound produced by the earbuds.
Sony WF 1000XM4's lowest frequency is at 20Hz, low-frequency response inidcates how well a particular audio component generates low frequencies that can be heard, 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 generates high human frequencies and if it adjustments to the signal on its way through. SPL, 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. A device's battery life is given by the manufacturer, and with more battery hours, you get to use it for longer and have to charge the device less often.
