Has Active Noise Cancellation (Noise Control)
Bose QuietComfort Earbuds II
✓
JEET W1S ✗
Active noise cancellation uses advanced technology to reduce unwanted ambient sounds. How it works, it detects and analyzes the sound pattern of incoming noise and then inverts the soundwaves to counter it. In simple terms, it's like having +1 (sound from your surrounding) and adding -1 (counter sound by the device) to make 0 hence "diluting" the noise.
The Bose QuietComfort Earbuds II have ANC allowing you to listen at lower volume levels, causing less ear fatigue since you don't need to crank up the device volume to outcompete background sounds.
Has Passive Noise Reduction
Bose QuietComfort Earbuds II
✓
JEET W1S ✓
Bose QuietComfort Earbuds II stay tightly in place, creating a sound seal that reduces background sounds and also prevents the earbuds sound from leaking out .
Both of these devices have passive noise reduction this implies that both limit ambient noise without using technology to cancel it out.
Driver Unit Size
Bose QuietComfort Earbuds II
9.3mm
JEET W1S 11mm
The Bose QuietComfort Earbuds II driver unit is 9.3mm in diameter, the bigger the unit the more powerful, and can produce better bass.
A driver unit is the component that makes sound in the device, the unit size determines the loudness of the device.
JEET W1S driver unit is 11mm in diameter,
making them have a larger driver unit than that of Bose QuietComfort Earbuds II by 1.7mm
, 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 mean that they produce better quality sound.
Lowest Frequency
Bose QuietComfort Earbuds II
20Hz
JEET W1S 20Hz
The Bose QuietComfort Earbuds II's lowest frequency is at 20Hz, low-frequency response inidcates how well an audio device produces low recognizable frequencies and if it alters the signal on its way through.
JEET W1S's lowest frequency is at 20Hz, this means that
both devices produce equal bass
Highest Frequency
Bose QuietComfort Earbuds II
20000Hz
JEET W1S 20000Hz
Bose QuietComfort Earbuds II's highest frequency is at 20000Hz, high-frequency response indicates how well a particular audio device generates high human frequencies and if it adjustments to the signal on its way through.
JEET W1S's highest frequency is at 20000Hz, this implies that
both devices produce equal treble
Sound Pressure Level
Bose QuietComfort Earbuds II
✗
JEET W1S 93dB/mW
The sound pressure level, is the pressure level of sound, in decibels, dB, JEET W1S's measurement is 93dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
