Has Active Noise Cancellation (Noise Control)
Sony WF 1000XM4
✓
Nuraphone NuraTrue ✓
ANC utilises more advanced technology to actively counter noise. How it works, it studies the sound pattern outside and inside the earbud and then generates a mirror signal to cancel it out. Simply put, it's like taking +1 (noise) then producing -1 (counter sound by the device) giving 0 hence "diluting" the noise.
Nuraphone NuraTrue have ANC enabling you to listen at lower volume levels, causing less ear fatigue since you don't need to crank up the device volume to outcompete background sounds.
Sony WF 1000XM4 too have Active Noise Cancellation making either of the devices ideal for plane rides and morning travels. The Nuraphone NuraTrue and Sony WF 1000XM4 operate with different noise cancellation settings, pick the mode that suits your travel or that suites your relaxation time.
Has Passive Noise Reduction

✓
Nuraphone NuraTrue ✓
Nuraphone NuraTrue sit tightly in place, creating a sound covering that reduces background noise and also prevents the earbuds voice audio from leaking out .
Both of these devices 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
Nuraphone NuraTrue 10mm
Nuraphone NuraTrue driver unit is 10mm in diameter, the bigger the unit the more powerful, therefor producing better bass.
A driver unit is basically a mini speaker that produces sound in the device, its size determines 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 Nuraphone NuraTrue by 4mm
, a common assumption that driver units of a bigger size automatically produce better sound quality.
However, large drivers find it difficult to produce high frequencies so yes, larger drivers can generate louder sound, but this does not mean that they produce better quality sound.
Lowest Frequency
Sony WF 1000XM4
20Hz
Nuraphone NuraTrue 20Hz
The Nuraphone NuraTrue's lowest frequency is at 20Hz, low-frequency response inidcates how well an audio component 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 means that
both devices produce equal bass
Highest Frequency
Sony WF 1000XM4
40000Hz
Nuraphone NuraTrue 20000Hz
The Nuraphone NuraTrue's highest frequency is at 20000Hz, high-frequency response measures if and how well an audio device makes high audible frequencies and if it changes to the signal on its way through.
Sony WF 1000XM4's highest frequency is at 40000Hz, this means that
Sony WF 1000XM4 can produce a clearer and crispier treble than the Nuraphone NuraTrue
Sound Pressure Level
Sony WF 1000XM4
✗
Nuraphone NuraTrue 108dB/mW
The sound pressure level, is the level of pressure of sound, measured in decibels, dB, Nuraphone NuraTrue's measurement is 108dB/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
✓
Nuraphone NuraTrue ✗
Sony WF 1000XM4 have neodymium magnets, if used in earbuds produce a higher sensitivity and substantial sound output while using less power. They can help produce music at quite a high SPL, with the use of high magnetic flux.
