Has Active Noise Cancellation (Noise Control)
Sony WF 1000XM4
✓
1More Aero ✓
Active noise cancellation utilises more advanced technology to actively counter noise. ANC works when, it studies the sound pattern outside and inside the earbud and generates a mirror signal to counter it. In simple terms, it's like taking +1 (noise) and producing -1 (inverted noise) to make zero therefore "diluting" the noise.
1More Aero have ANC enabling you to listen at lower volume levels, causing less ear fatigue as you don't have to crank up the device volume to overcome background noise.
Sony WF 1000XM4 too have ANC making either of the earbuds ideal for plane rides and rush hour travels. Each work with different noise cancellation modes, pick the noise cancellation type that you prefer for commute or that suites your chill time.
Has Passive Noise Reduction

1More Aero ✓
1More Aero stay well in place, creating a sound covering that tones down your environment noise while preventing the earbuds voice audio from leaking out .
Both of these devices have passive noise reduction this means that they tone down ambient noise without using ANC to cancel it out.
Driver Unit Size
Sony WF 1000XM4
6mm
1More Aero 10mm
The 1More Aero driver unit is 10mm 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 device, the unit size dictates 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 1More Aero by 4mm
, 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 it's true that, 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
1More Aero 20Hz
1More Aero's lowest frequency is at 20Hz, low-frequency response inidcates how well a particular audio component produces low audible frequencies and if it alters the signal while at it.
Sony WF 1000XM4's lowest frequency is at 20Hz, this means that
both devices can make sound with equal bass
Highest Frequency
Sony WF 1000XM4
40000Hz
1More Aero 20000Hz
1More Aero's highest frequency is at 20000Hz, high-frequency response shows how well a particular audio component generates high recognizable frequencies and if it makes any adjustments to the signal while at it.
Sony WF 1000XM4's highest frequency is at 40000Hz, this implies that
Sony WF 1000XM4 generate a clearer and crispier treble than the 1More Aero
Has A Neodymium Magnet
Sony WF 1000XM4
✓
1More Aero ✗
Sony WF 1000XM4 have neodymium magnets, when 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 SPL, using high magnetic flux.
