Ingress protection ratings refer to the level of protection given by a casing, against dust and liquids. The letters 'IP' are followed by two values The first value of the IP rating represents protection against solids say dust, while the second 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 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. Sony WF 1000XM4 have a weight of 7.1g . We consider a lower weight better because lighter devices are more comfortable to move with.
True wireless devices have no cables linking any part of the device together, Sony WF 1000XM4 are true wireless for this case since they don't have wires. This is a key distinction since wireless earbuds have wires linking the two earbuds .
Sony WF 1000XM4 are resistant to sweat
Sony WF 1000XM4 have stereo speakers, devices with stereo speakers deliver sound from independent channels on both left and right sides, this creates a richer sound and a better listening experience. ANC utilises advanced kind of tech to reduce unwanted ambient sounds.
ANC works when, it studies the sound pattern outside and inside the earbud and after generates a mirror signal to cancel it out. In simple terms, it's like taking +1 (noise) and producing -1 (counter sound by the device) to make 0 therefore "diluting" the noise.
Sony WF 1000XM4 have Active Noise Cancellation enabling you to listen at lower volume levels, good for your ears as you don't have to crank up the earbuds volume to overcome background noise.
Sony WF 1000XM4 stay tightly in place, creating a sound covering that tones down background noise while preventing the device music from leaking out at the same. Sony WF 1000XM4 driver unit is 6mm in diameter, bigger drivers are more powerful, therefor producing better bass. The driver unit is basically a mini speaker that makes sound in the earbuds, its size corellates with the loudness of the earbuds.
Sony WF 1000XM4's lowest frequency is at 20Hz, low-frequency response inidcates how well an audio device produces low audible frequencies and if it alters the signal on its way through. Sony WF 1000XM4's highest frequency is at 40,000Hz, high-frequency response tells how well a particular audio component generates high audible 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. Sony WF 1000XM4's battery life is 8 hours, these last longer than 5 hours of listening which is considered average before recharge. A device's battery life is usually given by the manufacturer, and with longer battery life, you get to use it for longer and have to charge the device less often.

It supports 24-bit audio at 250kbps. Because it uses psychoacoustic modeling, it provides better results than other codecs at the same bit rate.
Being the highest quality codec that any Bluetooth-supporting Apple product supports, the Sony WF 1000XM4 will work fine with your iPad.
If you are planning 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. 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).
The Sony WF 1000XM4 have 4 microphones. The Sony WF 1000XM4 have a noise-canceling type of microphone, these microphones are intended to reduce background sounds from the earbuds' sound.
The Sony WF 1000XM4 support ambient sound mode, which uses microphones to channel ambient sound so that they can still be heard even while wearing the earbuds
