Has Active Noise Cancellation (Noise Control)

ANC makes use of more advanced technology to reduce ambient sounds. ANC works when, it listens to the sound pattern outside and inside the earbud and then inverts the soundwaves to counter it. Simply put, it's like having +1 (noise) then adding -1 (counter sound by the device) giving zero thus "diluting" the noise.
Bose QuietComfort Earbuds II have Active Noise Cancellation allowing you to listen at lower levels of volume, causing less ear fatigue since you don't have to crank up the device volume to overcome background noise.
The Sony LinkBuds S too have Active Noise Cancellation making both earbuds ideal for plane rides and rush hour travels. Each work with different noise cancellation types, pick the noise cancellation type that you prefer for commute or that enhances your relaxation time.

Bose QuietComfort Earbuds II sit well in place, creating an acoustic seal that reduces your environment sounds and also prevents the device music from leaking out at the same.
Both of these devices have passive noise reduction which means that they tone down ambient noise without using ANC to cancel it out.
Driver Unit Size
Bose QuietComfort Earbuds II
9.3mm
Sony LinkBuds S 5mm
Bose QuietComfort Earbuds II driver unit is 9.3mm in diameter, the bigger the unit the more powerful, therefor producing better bass.
A driver unit is the component that produces sound in the device, its size corellates with the sound made by the earbuds.
Sony LinkBuds S driver unit is 5mm in diameter,
which implies that they have a smaller driver unit than that of Bose QuietComfort Earbuds II by 4.3mm
, 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 yes, larger drivers can generate louder sound, but this does not mean that they deliver better quality sound.
Lowest Frequency
Bose QuietComfort Earbuds II
20Hz
Sony LinkBuds S 20Hz
Bose QuietComfort Earbuds II's lowest frequency is at 20Hz, low-frequency response inidcates how well an audio component generates low recognizable frequencies and if it alters the signal on its way through.
Sony LinkBuds S's lowest frequency is at 20Hz, this means that
both devices produce equal bass
Highest Frequency
Bose QuietComfort Earbuds II
20000Hz
Sony LinkBuds S 40000Hz
The Bose QuietComfort Earbuds II's highest frequency is at 20000Hz, high-frequency response indicates how well an audio device makes high recognizable frequencies and if it makes any changes to the signal while at it.
Sony LinkBuds S's highest frequency is at 40000Hz, this implies that
Sony LinkBuds S generate a clearer and crispier treble than the Bose QuietComfort Earbuds II
