Has Active Noise Cancellation (Noise Control)
Sony WF 1000XM4
✓
OnePlus Buds Z2 ✓
Active noise cancellation uses more advanced kind of tech to actively counter noise. How it works, it detects and analyzes the sound pattern outside and inside the earbud and after generates a mirror signal to cancel it out. Simply put, it's like taking +1 (noise) then producing -1 (inverted noise) to make 0 therefore "diluting" the noise.
The OnePlus Buds Z2 have Active Noise Cancellation allowing you to listen at lower levels of volume, good for your ears as you don't have to crank up the earbuds volume to outcompete background sounds.
Sony WF 1000XM4 too have ANC which makes either of the devices ideal for plane rides and morning commutes. Each operate with different noise cancellation types, pick the mode that suits your travel or that enhances your chill time.

OnePlus Buds Z2 sit tightly in place, this creates an acoustic covering that tones down your environment noise and also prevents the earbuds music from leaking out at the same.
Both Sony WF 1000XM4, and OnePlus Buds Z2 have passive noise reduction this means that they limit ambient noise instead of actively using technology to cancel it out.
Driver Unit Size
Sony WF 1000XM4
6mm
OnePlus Buds Z2 11mm
OnePlus Buds Z2 driver unit is 11mm in diameter, the bigger the unit the more powerful, therefor producing better bass.
A driver unit is the component that produces sound in the earbuds, the unit size dictates the loudness of the device.
Sony WF 1000XM4 driver unit is 6mm in diameter,
which implies that they have a smaller driver unit than that of OnePlus Buds Z2 by 5mm
, 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 imply that they produce better quality sound.
Lowest Frequency
Sony WF 1000XM4
20Hz
OnePlus Buds Z2 20Hz
OnePlus Buds Z2's lowest frequency is at 20Hz, low-frequency response inidcates how well an audio component produces low recognizable frequencies and if it makes any changes to 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
OnePlus Buds Z2 20000Hz
OnePlus Buds Z2's highest frequency is at 20000Hz, high-frequency response indicates how well an audio component produces high human frequencies and if it makes any adjustments to the signal on its way through.
Sony WF 1000XM4's highest frequency is at 40000Hz, this means that
Sony WF 1000XM4 generate a clearer and crispier treble than the OnePlus Buds Z2
Sound Pressure Level
Sony WF 1000XM4
105dB/mW
OnePlus Buds Z2 ✗
SPL, is the level of pressure 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.
Has A Neodymium Magnet
Sony WF 1000XM4
✓
OnePlus Buds Z2 ✗
The 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, with the use of high magnetic flux.
