Has Active Noise Cancellation (Noise Control)

JBL Tune 225TWS ✗
Active noise cancellation utilises more advanced kind of tech to actively cancel noise. ANC works when, it studies the sound pattern outside and inside the earbud and after generates a mirror signal to counter it. Simply put, it's like taking +1 (sound from your surrounding) and adding -1 (counter sound by the device) giving zero thus "diluting" the noise.
The Samsung Galaxy Buds 2 Pro 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 overcome background sounds.
Has Passive Noise Reduction

JBL Tune 225TWS ✓
JBL Tune 225TWS sit well in place, this creates an acoustic covering that tones down background noise while preventing the device voice audio from leaking out at the same.
Both Samsung Galaxy Buds 2 Pro, and JBL Tune 225TWS have passive noise reduction which means that they reduce ambient noise instead of actively using technology to cancel it out.
Driver Unit Size
Samsung Galaxy Buds 2 Pro
10mm
JBL Tune 225TWS 12mm
The JBL Tune 225TWS driver unit is 12mm in diameter, the bigger the unit the more powerful, and can produce better bass.
A driver unit is the component that produces sound in the device, its size dictates the loudness of the device.
Samsung Galaxy Buds 2 Pro driver unit is 10mm in diameter,
which implies that they have a smaller driver unit than that of JBL Tune 225TWS by 2mm
, 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 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 Tune 225TWS 20Hz
JBL Tune 225TWS's lowest frequency is at 20Hz, low-frequency response inidcates how well an audio component generates low frequencies that can be heard, and if it alters the signal while at it.
Samsung Galaxy Buds 2 Pro's lowest frequency is at 20Hz, this means that
both devices can make sound with equal bass
Highest Frequency
Samsung Galaxy Buds 2 Pro
20000Hz
JBL Tune 225TWS 20000Hz
JBL Tune 225TWS's highest frequency is at 20000Hz, high-frequency response tells how well a particular audio component makes high recognizable frequencies and if it makes any changes to the signal on its way through.
Samsung Galaxy Buds 2 Pro's highest frequency is at 20000Hz, this means that
both devices can generate equal treble
Sound Pressure Level
Samsung Galaxy Buds 2 Pro
25dB/mW
JBL Tune 225TWS 105dB/mW
The sound pressure level, is the pressure level of sound, measured in decibels, dB, JBL Tune 225TWS's measurement is 105dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
Samsung Galaxy Buds 2 Pro's sound pressure level measurement is 25dB/mW. The sound pressure level, something is can be considered differently by separate persons, so we need to have the means to get a standard measurement of sound level expressed in numerical terms.
