The Bose QuietComfort 2 also have stereo speakers
Active noise cancellation uses more advanced kind of tech to reduce ambient sounds. ANC works when, it detects and analyzes the sound pattern of incoming noise and after generates a mirror signal to cancel it out. In simple terms, it's like taking +1 (noise) and adding -1 (inverted noise) giving zero hence "diluting" the noise.
The JBL Tune Flex have Active Noise Cancellation enabling you to listen at lower volume levels, good for your ears as you don't need to crank up the device volume to outcompete background noise.

JBL Tune Flex have a unit size of 12mm in diameter, bigger drivers are more powerful, and can produce better bass. A driver unit is the component that makes sound in the earbuds, the unit size determines the loudness of the device.
Bose QuietComfort 2 driver unit is 9.3mm in diameter,
which implies that they have a smaller driver unit than that of JBL Tune Flex by 2.7mm
, many people have a misconception that driver units of a bigger size automatically produce better sound quality.
However, large drivers usually have difficulty producing high frequencies so yeah, larger drivers can generate louder sound, but this does not imply that they deliver better quality sound. JBL Tune Flex's lowest frequency is at 20Hz, low-frequency response inidcates how well a particular audio device generates low recognizable frequencies and if it alters the signal on its way through.
Bose QuietComfort 2's lowest frequency is at 20Hz, this implies that
both devices make sound with equal bass
The JBL Tune Flex's highest frequency is at 20,000Hz, high-frequency response shows how well an audio device makes high human frequencies and if it adjustments to the signal while at it. Bose QuietComfort 2's highest frequency is at 20,000Hz, this implies 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.
JBL Tune Flex's battery life is 8 hours, these last longer than 5 hours of listening which is considered average before recharge.
