Sound Quality

Has Active Noise Cancellation (Noise Control)

Devialet Gemini 2
JBL Reflect Aero TWS

ANC uses advanced technology to reduce unwanted ambient sounds. How it works, it studies the sound pattern of incoming noise and after generates a mirror signal to counter it. Simply put, it's like taking +1 (noise) and producing -1 (inverted noise) giving zero resulting in a reduced level of noise.

The Devialet Gemini 2 have ANC 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 noise.

JBL Reflect Aero TWS too have Active Noise Cancellation making either of the earbuds ideal for flights and morning commutes. The Devialet Gemini 2 and JBL Reflect Aero TWS work with different noise cancellation types, pick the setting that suits your travel or that suites your relaxation time.

Driver Unit Size

Devialet Gemini 2 10mm
JBL Reflect Aero TWS 6.8mm

The Devialet Gemini 2 have a unit size of 10mm in diameter, bigger drivers are more powerful, therefor producing better bass. A driver unit is basically a mini speaker that produces sound in the earbuds, its size dictates the sound produced by 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 Devialet Gemini 2 by 3.2mm , many people have a misconception that driver units of a bigger size automatically produce better sound quality.

However, large drivers find it difficult to produce high frequencies so yeah, larger drivers are capable of generating louder sound, but this does not mean that they deliver better quality sound.

JBL Reflect Aero TWS's highest frequency is at 20,000Hz, this means that both devices generate equal treble

Sound Pressure Level

Devialet Gemini 2 120dB/mW
JBL Reflect Aero TWS 99dB/mW

SPL, is the level of pressure of sound, measured in decibels, dB, Devialet Gemini 2's measurement is 120dB/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 people, so we need to have a way of getting an objective measurement of sound level expressed in numerical terms.
