Has Active Noise Cancellation (Noise Control)
Sony WF 1000XM4
✓
Huawei FreeBuds 5i ✓
ANC uses advanced kind of tech to actively cancel noise. ANC works when, it studies 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) and producing -1 (inverted noise) to make 0 thus "diluting" the noise.
Huawei FreeBuds 5i have Active Noise Cancellation enabling you to listen at lower levels of volume, good for your ears since you don't have to crank up the device volume to overcome background noise.
The Sony WF 1000XM4 too have ANC making both earbuds ideal for flights and rush hour commutes. Each work with different noise cancellation modes, pick the noise cancellation type that suits your commute or that suites your relaxation time.
Has Passive Noise Reduction
Sony WF 1000XM4
✓
Huawei FreeBuds 5i ✓
The Huawei FreeBuds 5i sit tightly in place, creating an acoustic covering that reduces your environment sounds and also prevents the earbuds music from leaking out at the same.
Both of these devices have passive noise reduction which means that they reduce ambient noise instead of actively using technology to cancel it out.
Driver Unit Size
Sony WF 1000XM4
6mm
Huawei FreeBuds 5i 10mm
Huawei FreeBuds 5i driver unit is 10mm in diameter, bigger drivers are more powerful, therefor producing better bass.
The driver unit is basically a mini speaker that produces sound in the device, the unit size corellates with the sound made by the device.
Sony WF 1000XM4 driver unit is 6mm in diameter,
which means that they have a smaller driver unit than that of Huawei FreeBuds 5i by 4mm
, as many tend to believe that driver units of a bigger size automatically produce better sound quality.
However, large drivers find it difficult to produce high frequencies so it's true that, larger drivers are capable of generating louder sound, but this does not indicate that they produce better quality sound.
Lowest Frequency
Sony WF 1000XM4
20Hz
Huawei FreeBuds 5i 20Hz
Huawei FreeBuds 5i's lowest frequency is at 20Hz, low-frequency response measures if and how well an audio component generates 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 can produce equal bass
Highest Frequency
Sony WF 1000XM4
40000Hz
Huawei FreeBuds 5i 40000Hz
The Huawei FreeBuds 5i's highest frequency is at 40000Hz, high-frequency response indicates how well a particular audio device generates high human 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
both devices can produce equal treble
Sound Pressure Level
Sony WF 1000XM4
105dB/mW
Huawei FreeBuds 5i ✗
SPL, is the pressure level of sound, measured 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
✓
Huawei FreeBuds 5i ✗
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 produce music at quite a high sound pressure level, with the use of high magnetic flux.
