Overall Score 7.9 Represents average audio ecosystem compatibility score.
Ingress protection ratings is the level of protection given by an enclosure, against solids and water. The letters 'IP' are followed by two values The first value of the IP rating means protection against solids such as dust, while the second refers to resistance against liquids (sweat).
Scoring 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 take in account a lower weight better because lighter devices are more comfortable to move with.
For a device to be true wireless it must have no cables linking any part of the device together, Sony WF 1000XM4 are true wireless for this matter since they don't have cables. This is a key difference as some wireless earbuds have wires linking the pair of earbuds together.
Sony WF 1000XM4 are resistant to sweat
The earbud foam is made to be ultracompact and lightweight, with almost no interference with earrings, spectacles, hats, or hairstyles. The Sony WF 1000XM4 have an earbud foam to some it is more comfortable than the in-ear foam.
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.
Active noise cancellation makes use of more advanced technology to reduce ambient sounds. ANC works when, it detects and analyzes the sound pattern outside and inside the earbud and after generates a mirror signal to counter it. In simple terms, it's like having +1 (sound from your surrounding) and adding -1 (inverted noise) to make 0 hence "diluting" the noise.
The Sony WF 1000XM4 have ANC enabling you to listen at lower levels of volume, good for your ears since you don't have to crank up the earbuds volume to outcompete background sounds.

Sony WF 1000XM4 driver unit is 6mm in diameter, the bigger the unit the more powerful, therefor producing better bass. A driver unit is the component that makes sound in the earbuds, its size corellates with the sound made by the earbuds.
Sony WF 1000XM4's lowest frequency is at 20Hz, low-frequency response measures if and how well a particular audio component produces low frequencies that can be heard, and if it alters the signal on its way through.
The Sony WF 1000XM4's highest frequency is at 40000Hz, high-frequency response measures if and how well a particular audio component makes high recognizable 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.
Sony WF 1000XM4 have neodymium magnets, if used in earbuds produce a higher sensitivity and substantial sound output using less power to do so. They can help generate music at quite a high sound pressure level, using high magnetic flux.
The 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 commonly given by the manufacturer, and with more battery hours, you get to use it for longer and have to charge the device less often.

The Sony WF 1000XM4 have a 10meters distance to connect via Bluetooth.
Sony WF 1000XM4 support AAC, a codec used for Bluetooth audio. It supports 24-bit audio at 250kbps. Since it uses psychoacoustic modeling, it can provide better results than other codecs at a similar bit rate.
Being the highest quality codec that any Bluetooth-supporting Apple product supports, the Sony WF 1000XM4 will work fine with your MacBook. 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 can reach a high bitrate of 990kbps, which provides 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).
Latency refers to the time it takes for the audio signal to be transmitted to your earbuds. Sony WF 1000XM4 have a latency of 40ms, a lower latency reduces audio lag and is particularly important when playing games or watching videos.
Sony WF 1000XM4 have a noise-canceling microphone, these microphones are designed to reduce noise from the desired 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 them
