Has Active Noise Cancellation (Noise Control)
JEET W1S
✗
JBL Reflect Aero TWS ✓
Active noise cancellation uses advanced technology to reduce unwanted ambient sounds. How it works, it detects and analyzes the sound pattern outside and inside the earbud and after inverts the soundwaves to counter it. Simply put, it's like having +1 (sound from your surrounding) and adding -1 (inverted noise) giving zero therefore "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 outcompete background noise.
Has Passive Noise Reduction
JEET W1S
✓
JBL Reflect Aero TWS ✓
The JBL Reflect Aero TWS stay well in place, this creates a sound covering that reduces your environment sounds well as preventing the earbuds music from leaking out at the same.
Both of these devices have passive noise reduction which implies that both reduce ambient noise without using ANC to cancel it out.
Driver Unit Size
JEET W1S
11mm
JBL Reflect Aero TWS 6.8mm
The JBL Reflect Aero TWS driver unit is 6.8mm in diameter, the bigger the unit the more powerful, therefor producing better bass.
The driver unit is basically a mini speaker that makes sound in the earbuds, the unit size dictates the loudness of the device.
JEET W1S driver unit is 11mm in diameter,
making them have a larger driver unit than that of JBL Reflect Aero TWS by 4.2mm
, 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 yeah, larger drivers are capable of generating louder sound, but this does not mean that they produce better quality sound.
Lowest Frequency
JEET W1S
20Hz
JBL Reflect Aero TWS 20Hz
JBL Reflect Aero TWS's lowest frequency is at 20Hz, low-frequency response inidcates how well an audio device produces low frequencies that can be heard, and if it alters the signal while at it.
JEET W1S's lowest frequency is at 20Hz, this means that
both devices make sound with equal bass
Highest Frequency
JEET W1S
20000Hz
JBL Reflect Aero TWS 20000Hz
The JBL Reflect Aero TWS's highest frequency is at 20000Hz, high-frequency response indicates how well a particular audio component produces high human frequencies and if it adjustments to the signal while at it.
JEET W1S's highest frequency is at 20000Hz, this means that
both devices generate equal treble
Sound Pressure Level
JEET W1S
93dB/mW
JBL Reflect Aero TWS 99dB/mW
SPL, is the pressure level of sound, in decibels, dB, JBL Reflect Aero TWS's measurement is 99dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
JEET W1S's sound pressure level measurement is 93dB/mW. The sound pressure level, something is can be considered differently by separate persons, so we need to have a way of getting a standard measurement of sound level expressed in numerical terms.
