IP ratings is the level of protection offered by a casing, against dust and water. 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 (sweat).
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 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 have a weight of 7.1g . We prefer a lower weight best because lighter devices are easier to move with.

ANC uses more advanced kind of tech to actively cancel noise. How it works, it listens to the sound pattern of incoming noise and then inverts the soundwaves to counter it. In simple terms, it's like taking +1 (noise) and adding -1 (counter sound by the device) giving zero which results in a reduced level of noise.
The Sony WF 1000XM4 have ANC enabling you to listen at lower levels of volume, causing less ear fatigue since you don't have to crank up the device volume to overcome background sounds.

A driver unit is basically a mini speaker that makes sound in the earbuds, its size determines the sound made by the earbuds. Sony WF 1000XM4's lowest frequency is at 20Hz, low-frequency response inidcates how well an audio device generates low frequencies that can be heard, and if it alters the signal while at it. The Sony WF 1000XM4's highest frequency is at 40,000Hz, high-frequency response shows how well a particular audio device generates 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. 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.

If you intend on using these with Android you need to pay even closer attention to codec support for if they only have AAC they won't provide the best audio quality possible, ensure that they also support aptX HD, LDAC, or LHDC as well. The Sony WF 1000XM4 support LDAC, a codec developed by Sony
which allows streaming high-resolution audio over Bluetooth connections at up to 990 kbps at 32 bit/96 kHz.
It is capable of a very high bitrate of 990kbps, providing high-resolution audio. The Sony WF 1000XM4 support APTX HD, an audio codec for Bluetooth devices that are developed by Qualcomm. It supports high-quality 24-bit audio (at a bit rate of 576kbps).
Sony WF 1000XM4 have 4 microphones.
The Sony WF 1000XM4 have a noise-canceling type of microphone, these microphones are intended to filter out background sounds from the desired sound.
