Nuraphone NuraTrue ✓
ANC makes use of advanced technology to reduce unwanted ambient sounds. ANC works when, it detects and analyzes the sound pattern outside and inside the earbud and inverts the soundwaves to counter it. Simply put, it's like having +1 (sound from your surrounding) and adding -1 (counter sound by the device) to make zero which results in a reduced level of noise.
The Nuraphone NuraTrue have Active Noise Cancellation allowing you to listen at lower levels of volume, good for your ears as you don't need to crank up the device volume to overcome background noise.
Sony WF 1000XM4 too have Active Noise Cancellation making either of the earbuds ideal for flights and rush hour travels. Each operate with different noise cancellation settings, pick the noise cancellation type that suits your commute or that suites your chill time.
Has Passive Noise Reduction

Nuraphone NuraTrue ✓
The Nuraphone NuraTrue sit well in place, this creates an acoustic seal that reduces background sounds and also prevents the device voice audio from leaking out .
Both Sony WF 1000XM4, and Nuraphone NuraTrue have passive noise reduction which implies that both reduce ambient noise instead of actively using ANC to cancel it out.
Driver Unit Size
Sony WF 1000XM4
6mm
Nuraphone NuraTrue 10mm
The Nuraphone NuraTrue driver unit is 10mm in diameter, bigger drivers are more powerful, therefor producing better bass.
The driver unit is the component that makes sound in the earbuds, the unit size determines the loudness of the earbuds.
Sony WF 1000XM4 driver unit is 6mm in diameter,
which means that they have a smaller driver unit than that of Nuraphone NuraTrue by 4mm
, many people have a misconception that driver units of a bigger size automatically produce better sound quality.
However, large drivers find it difficult to produce high frequencies so yeah, larger drivers can generate louder sound, but this does not imply 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 measures if and how well a particular audio component produces low recognizable 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
Nuraphone NuraTrue 20000Hz
The Nuraphone NuraTrue's highest frequency is at 20000Hz, high-frequency response measures if and how well a particular audio device makes high recognizable frequencies and if it adjustments to the signal on its way through.
Sony WF 1000XM4's highest frequency is at 40000Hz, this implies that
Sony WF 1000XM4 can produce a clearer and crispier treble than the Nuraphone NuraTrue
Sound Pressure Level
Sony WF 1000XM4
105dB/mW
Nuraphone NuraTrue 108dB/mW
The sound pressure level, is the pressure level of sound, 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.
Sony WF 1000XM4's sound pressure level measurement is 105dB/mW. How loud a device is can be taken differently by different people, 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
✓
Nuraphone NuraTrue ✗
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 produce music at quite a high SPL, using high magnetic flux.
