Has Active Noise Cancellation (Noise Control)
Sony WF 1000XM4
✓
Skullcandy Indy Fuel ✗
Active noise cancellation utilises more advanced kind of tech to actively cancel noise. How it works, it detects and analyzes the sound pattern of incoming noise and then inverts the soundwaves to counter it. Simply put, it's like taking +1 (sound from your surrounding) then producing -1 (counter sound by the device) to make 0 hence "diluting" the noise.
The Sony WF 1000XM4 have Active Noise Cancellation allowing you to listen at lower volume levels, good for your ears as you don't have to crank up the device volume to overcome background noise.
Has Passive Noise Reduction
Sony WF 1000XM4
✓
Skullcandy Indy Fuel ✓
The Skullcandy Indy Fuel stay well in place, creating a sound seal that tones down background noise and also prevents the device music from leaking out at the same.
Both of these devices have passive noise reduction which implies that they reduce ambient noise instead of actively using ANC to cancel it out.
Driver Unit Size
Sony WF 1000XM4
6mm
Skullcandy Indy Fuel 6mm
The Skullcandy Indy Fuel have a unit size of 6mm in diameter, the bigger the unit the more powerful, and can produce better bass.
A driver unit is basically a mini speaker that makes sound in the earbuds, the unit size corellates with the sound produced by the earbuds.
Sony WF 1000XM4 driver unit is 6mm in diameter,
making both devices similar in how loud their sound gets
, 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 yeah, larger drivers can generate louder sound, but this does not mean that they deliver better quality sound.
Lowest Frequency
Sony WF 1000XM4
20Hz
Skullcandy Indy Fuel 20Hz
The Skullcandy Indy Fuel's lowest frequency is at 20Hz, low-frequency response inidcates how well a particular audio device generates low frequencies that can be heard, and if it alters 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
Skullcandy Indy Fuel 20000Hz
The Skullcandy Indy Fuel's highest frequency is at 20000Hz, high-frequency response tells how well a particular audio component makes high human frequencies and if it makes any changes to the signal while at it.
Sony WF 1000XM4's highest frequency is at 40000Hz, this means that
Sony WF 1000XM4 produce a clearer and crispier treble than the Skullcandy Indy Fuel
Sound Pressure Level
Sony WF 1000XM4
105dB/mW
Skullcandy Indy Fuel 105dB/mW
SPL, is the level of pressure of sound, measured in decibels, dB, Skullcandy Indy Fuel's measurement is 105dB/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 separate persons, so we need to have a way of getting a standard measurement of sound level expressed in numerical terms.
Has A Neodymium Magnet
Sony WF 1000XM4
✓
Skullcandy Indy Fuel ✗
The 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 generate music at quite a high sound pressure level, using high magnetic flux.
