IP ratings refer to the rating of protection given by an enclosure, against dust and liquids. The letters 'IP' are followed by two values The first value of the IP rating means protection against solids such as dust, followed by the one that refers to resistance against liquids (water).
Scoring IPX4, the Sony WF 1000XM4's rating is read as, the first value of X denotes 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 Sony WF 1000XM4's lowest frequency is at 20Hz, low-frequency response measures if and how well an audio device generates low recognizable frequencies and if it alters the signal while at it. Sony WF 1000XM4's highest frequency is at 40,000Hz, high-frequency response shows how well an audio device generates high recognizable frequencies and if it makes any changes to the signal while at it. 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 before recharge.
