Has Active Noise Cancellation (Noise Control)

JBL Endurance Peak 3 ✗
Active noise cancellation utilises advanced technology to reduce ambient sounds. How it works, it listens to the sound pattern outside and inside the earbud and after inverts the soundwaves to cancel it out. In simple terms, it's like taking +1 (noise) and adding -1 (counter sound by the device) giving 0 which results in a reduced level of noise.
The Bose QuietComfort Earbuds 2 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 sounds.
Has Passive Noise Reduction

JBL Endurance Peak 3 ✓
The JBL Endurance Peak 3 stay tightly in place, this creates a sound seal that reduces background noise and also prevents the earbuds voice audio from leaking out .
Both of these devices have passive noise reduction this means that they tone down ambient noise instead of actively using technology to cancel it out.
Driver Unit Size
Bose QuietComfort Earbuds 2
9.3mm
JBL Endurance Peak 3 10mm
JBL Endurance Peak 3 have a unit size of 10mm in diameter, bigger drivers are more powerful, therefor producing better bass.
The driver unit is the component that makes sound in the device, its size determines the sound produced by the device.
Bose QuietComfort Earbuds 2 driver unit is 9.3mm in diameter,
which means that they have a smaller driver unit than that of JBL Endurance Peak 3 by 0.7mm
, many people have a misconception that driver units of a bigger size automatically produce better sound quality.
However, large drivers find it difficult to produce high frequencies so yes, larger drivers are capable of generating louder sound, but this does not indicate that they deliver better quality sound.
Lowest Frequency
Bose QuietComfort Earbuds 2
20Hz
JBL Endurance Peak 3 20Hz
The JBL Endurance Peak 3'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 alters the signal on its way through.
Bose QuietComfort Earbuds 2's lowest frequency is at 20Hz, this implies that
both devices can produce equal bass
Highest Frequency
Bose QuietComfort Earbuds 2
20,000Hz
JBL Endurance Peak 3 20,000Hz
The JBL Endurance Peak 3's highest frequency is at 20,000Hz, 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.
Bose QuietComfort Earbuds 2's highest frequency is at 20,000Hz, this means that
both devices can produce equal treble
Sound Pressure Level
Bose QuietComfort Earbuds 2
✗
JBL Endurance Peak 3 102dB/mW
SPL, is the pressure level of sound, measured in decibels, dB, JBL Endurance Peak 3's measurement is 102dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
