ANC makes use of more advanced technology to actively cancel noise.
How it works, it detects and analyzes the sound pattern of incoming noise and then generates a mirror signal to cancel it out. In simple terms, it's like taking +1 (noise) then adding -1 (counter sound by the device) giving 0 which results in a reduced level of noise.
JBL Tune Flex 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 earbuds volume to outcompete background noise.
Bose QuietComfort Earbuds 2 too have ANC which makes both devices ideal for flights and rush hour travels. Each work with different noise cancellation modes, pick the mode that you prefer for travel or that suites your relaxation time. The JBL Tune Flex stay tightly in place, this creates an acoustic covering that tones down background sounds while preventing the earbuds sound from leaking out at the same.
Both of these devices have passive noise reduction this implies that they limit ambient noise instead of actively using ANC to cancel it out. JBL Tune Flex have a unit size of 12mm in diameter, bigger drivers are more powerful, and can produce better bass. The driver unit is basically a mini speaker that produces sound in the earbuds, the unit size corellates with the sound produced by the earbuds.
Bose QuietComfort Earbuds 2 driver unit is 9.3mm in diameter,
which means that they have a smaller driver unit than that of JBL Tune Flex by 2.7mm
, a common assumption 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 imply that they deliver better quality sound. The JBL Tune Flex's lowest frequency is at 20Hz, low-frequency response inidcates how well a particular audio component produces low frequencies that can be heard, and if it alters the signal while at it.
Bose QuietComfort Earbuds 2's lowest frequency is at 20Hz, this implies that
both devices produce equal bass
JBL Tune Flex's highest frequency is at 20,000Hz, high-frequency response shows how well a particular audio component generates high recognizable frequencies and if it changes to the signal while at it. Bose QuietComfort Earbuds 2's highest frequency is at 20,000Hz, this means that
both devices can generate equal treble
SPL, is the pressure level of sound, measured in decibels, dB, JBL Tune Flex's measurement is 108dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
The JBL Tune Flex's battery life is 8 hours, these last longer than 5 hours of listening which is considered average before recharge.
