Has Active Noise Cancellation (Noise Control)
Samsung Galaxy Buds 2 Pro

JBL Reflect Aero TWS ✓
ANC utilises advanced kind of tech to reduce ambient sounds. ANC works when, it detects and analyzes the sound pattern outside and inside the earbud and generates a mirror signal to cancel it out. Simply put, it's like having +1 (sound from your surrounding) then adding -1 (counter sound by the device) to make 0 thus "diluting" the noise.
Samsung Galaxy Buds 2 Pro have Active Noise Cancellation enabling you to listen at lower levels of volume, good for your ears since you don't have to crank up the earbuds volume to overcome background sounds.
JBL Reflect Aero TWS too have Active Noise Cancellation making either of the earbuds ideal for flights and rush hour commutes. The Samsung Galaxy Buds 2 Pro and JBL Reflect Aero TWS work with different noise cancellation types, pick the noise cancellation type that you prefer for travel or that suites your relaxation time.

Driver Unit Size
Samsung Galaxy Buds 2 Pro
10mm
JBL Reflect Aero TWS 6.8mm
The Samsung Galaxy Buds 2 Pro driver unit is 10mm in diameter, bigger drivers are more powerful, therefor producing better bass.
A driver unit is the component that produces sound in the earbuds, the unit size dictates the sound made by the device.
JBL Reflect Aero TWS driver unit is 6.8mm in diameter,
which means that they have a smaller driver unit than that of Samsung Galaxy Buds 2 Pro by 3.2mm
, 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 it's true that, larger drivers are capable of generating louder sound, but this does not imply that they produce better quality sound.
Lowest Frequency
Samsung Galaxy Buds 2 Pro
20Hz
JBL Reflect Aero TWS 20Hz
Samsung Galaxy Buds 2 Pro's lowest frequency is at 20Hz, low-frequency response measures if and how well an audio component produces low frequencies that can be heard, and if it alters the signal while at it.
JBL Reflect Aero TWS's lowest frequency is at 20Hz, this implies that
both devices can make sound with equal bass
Highest Frequency
Samsung Galaxy Buds 2 Pro
20,000Hz
JBL Reflect Aero TWS 20,000Hz
Samsung Galaxy Buds 2 Pro's highest frequency is at 20,000Hz, high-frequency response shows how well a particular audio device generates high human frequencies and if it adjustments to the signal while at it.
JBL Reflect Aero TWS's highest frequency is at 20,000Hz, this implies that
both devices can produce equal treble
Sound Pressure Level
Samsung Galaxy Buds 2 Pro
25dB/mW
JBL Reflect Aero TWS 99dB/mW
SPL, is the pressure level of sound, in decibels, dB, Samsung Galaxy Buds 2 Pro's measurement is 25dB/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. How loud a device is can be perceived differently by separate persons, so we need to have the means to get a standard measurement of sound level expressed in numerical terms.
