Has Active Noise Cancellation (Noise Control)
Sony WF 1000XM4
✓
1More Aero ✓
ANC makes use of more advanced technology to actively counter noise. How it works, it listens to the sound pattern outside and inside the earbud and generates a mirror signal to counter it. Simply put, it's like taking +1 (sound from your surrounding) then producing -1 (inverted noise) giving zero resulting in a reduced level of noise.
1More Aero have Active Noise Cancellation enabling you to listen at lower volume levels, causing less ear fatigue as you don't need to crank up the earbuds volume to outcompete background noise.
Sony WF 1000XM4 too have Active Noise Cancellation making both devices ideal for plane rides and rush hour travels. The 1More Aero and Sony WF 1000XM4 work with different noise cancellation modes, pick the mode that you prefer for commute or that suites your chill time.
Has Passive Noise Reduction

✓
1More Aero ✓
1More Aero sit well in place, creating a sound covering that reduces background sounds and also prevents the device voice audio from leaking out at the same.
Both Sony WF 1000XM4, and 1More Aero have passive noise reduction this means that both reduce ambient noise without using ANC to cancel it out.
Driver Unit Size
Sony WF 1000XM4
6mm
1More Aero 10mm
1More Aero have a unit size of 10mm in diameter, the bigger the unit the more powerful, and can produce better bass.
The driver unit is basically a mini speaker that produces sound in the earbuds, its size determines the loudness of the device.
Sony WF 1000XM4 driver unit is 6mm in diameter,
which means 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 yeah, larger drivers can generate louder sound, but this does not indicate that they deliver 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 device produces low frequencies that can be heard, 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 produce equal bass
Highest Frequency
Sony WF 1000XM4
40000Hz
1More Aero 20000Hz
The 1More Aero's highest frequency is at 20000Hz, high-frequency response indicates how well a particular audio component makes high human frequencies and if it adjustments to the signal while at it.
Sony WF 1000XM4's highest frequency is at 40000Hz, this means that
Sony WF 1000XM4 generate a clearer and crispier treble than the 1More Aero
Sound Pressure Level
Sony WF 1000XM4
105dB/mW
1More Aero ✗
The sound pressure level, 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
✓
1More Aero ✗
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 SPL, with the use of high magnetic flux.
