Has Active Noise Cancellation (Noise Control)
Sony WF 1000XM4
✓
Anker Soundcore Liberty 3 Pro ✓
ANC utilises advanced kind of tech to reduce unwanted ambient sounds. How it works, it detects and analyzes the sound pattern of incoming noise and after inverts the soundwaves to cancel it out. In simple terms, it's like having +1 (noise) and adding -1 (counter sound by the device) giving 0 therefore "diluting" the noise.
The Anker Soundcore Liberty 3 Pro have Active Noise Cancellation allowing you to listen at lower levels of volume, good for your ears since you don't need to crank up the device volume to overcome background noise.
Sony WF 1000XM4 too have Active Noise Cancellation which makes either of the devices ideal for flights and morning travels. The Anker Soundcore Liberty 3 Pro and Sony WF 1000XM4 operate with different noise cancellation modes, pick the noise cancellation type that suits your travel or that enhances your relaxation time.

Driver Unit Size
Sony WF 1000XM4
6mm
Anker Soundcore Liberty 3 Pro 10.6mm
The Anker Soundcore Liberty 3 Pro driver unit is 10.6mm in diameter, the bigger the unit the more powerful, therefor producing better bass.
The driver unit is basically a mini speaker that produces sound in the earbuds, the unit size corellates with the loudness of the earbuds.
Sony WF 1000XM4 driver unit is 6mm in diameter,
which implies that they have a smaller driver unit than that of Anker Soundcore Liberty 3 Pro by 4.6mm
, a common assumption that driver units of a bigger size automatically produce better sound quality.
However, large drivers usually have difficulty producing high frequencies so yes, larger drivers are capable of generating louder sound, but this does not mean that they produce better quality sound.
Lowest Frequency
Sony WF 1000XM4
20Hz
Anker Soundcore Liberty 3 Pro 20Hz
The Anker Soundcore Liberty 3 Pro's lowest frequency is at 20Hz, low-frequency response measures if and how well a particular audio component generates low frequencies that can be heard, and if it alters the signal on its way through.
Sony WF 1000XM4's lowest frequency is at 20Hz, this implies that
both devices can produce equal bass
Highest Frequency
Sony WF 1000XM4
40000Hz
Anker Soundcore Liberty 3 Pro 40000Hz
The Anker Soundcore Liberty 3 Pro's highest frequency is at 40000Hz, high-frequency response measures if and how well an audio component produces high recognizable frequencies and if it changes to the signal while at it.
Sony WF 1000XM4's highest frequency is at 40000Hz, this means that
both devices generate equal treble
Sound Pressure Level
Sony WF 1000XM4
105dB/mW
Anker Soundcore Liberty 3 Pro 92dB/mW
The sound pressure level, is the level of pressure of sound, in decibels, dB, Anker Soundcore Liberty 3 Pro's measurement is 92dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
Sony WF 1000XM4's sound pressure level measurement is 105dB/mW. The sound pressure level, a device is can be considered differently by different persons, so we need to have a way of getting an objective measurement of sound level expressed in numerical terms.
Has A Neodymium Magnet
Sony WF 1000XM4
✓
Anker Soundcore Liberty 3 Pro ✗
The Sony WF 1000XM4 have neodymium magnets, when used in audio devices 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, with the use of high magnetic flux.
