✓
LG Tone Free Fit TF8 ✓
ANC uses more advanced technology to actively counter noise. How it works, it detects and analyzes the sound pattern outside and inside the earbud and generates a mirror signal to cancel it out. Simply put, it's like taking +1 (noise) and producing -1 (counter sound by the device) giving 0 therefore "diluting" the noise.
LG Tone Free Fit TF8 have Active Noise Cancellation enabling you to listen at lower levels of volume, causing less ear fatigue since you don't need to crank up the earbuds volume to outcompete background sounds.
Sony WF 1000XM4 too have ANC making both devices ideal for plane rides and morning travels. Each work with different noise cancellation modes, pick the noise cancellation type that you prefer for commute or that enhances your relaxation time.

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 usually have difficulty producing high frequencies so it's true that, larger drivers can generate louder sound, but this does not imply that they produce better quality sound.
Lowest Frequency
Sony WF 1000XM4
20Hz
LG Tone Free Fit TF8 20Hz
The LG Tone Free Fit TF8's lowest frequency is at 20Hz, low-frequency response inidcates how well a particular audio device produces low audible frequencies and if it makes any changes to the signal while at it.

both devices can make sound with equal bass
Highest Frequency
Sony WF 1000XM4
40000Hz
LG Tone Free Fit TF8 20000Hz
LG Tone Free Fit TF8's highest frequency is at 20000Hz, high-frequency response indicates how well a particular audio component generates high human frequencies and if it changes to the signal on its way through.
Sony WF 1000XM4's highest frequency is at 40000Hz, this implies that
Sony WF 1000XM4 can generate a clearer and crispier treble than the LG Tone Free Fit TF8
Sound Pressure Level
Sony WF 1000XM4
105dB/mW
LG Tone Free Fit TF8 ✗
SPL, is the level of pressure 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
✓
LG Tone Free Fit TF8 ✗
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 sound pressure level, using high magnetic flux.
