Has Active Noise Cancellation (Noise Control)

JBL Reflect Aero TWS ✓
Active noise cancellation utilises advanced kind of tech to reduce unwanted ambient sounds. How it works, it studies the sound pattern outside and inside the earbud and inverts the soundwaves to counter it. Simply put, it's like taking +1 (sound from your surrounding) then producing -1 (inverted noise) giving zero hence "diluting" the noise.
The JBL Reflect Aero TWS have Active Noise Cancellation enabling you to listen at lower volume levels, causing less ear fatigue as you don't need to crank up the earbuds volume to overcome background sounds.

A driver unit is basically a mini speaker that produces sound in the earbuds, its size determines the loudness of the earbuds.
JBL Reflect Aero TWS driver unit is 6.8mm in diameter,
which implies that they have a smaller driver unit than that of Ultimate Ears Drops by 2.4mm
, a common assumption 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 indicate that they deliver better quality sound.

Ultimate Ears Drops
110db/mw
JBL Reflect Aero TWS 99db/mw
SPL, is the pressure level of sound, measured in decibels, dB, Ultimate Ears Drops's measurement is 110dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
JBL Reflect Aero TWS's sound pressure level measurement is 99dB/mW. The sound pressure level, a device is can be considered differently by separate people, so we need to have a way of getting an objective measurement of sound level expressed in numerical terms.
