Both JBL Reflect Aero TWS and Devialet Gemini have stereo speakers
Active noise cancellation uses advanced technology to actively cancel noise. How it works, it listens to the sound pattern outside and inside the earbud and after generates a mirror signal to cancel it out. Simply put, it's like having +1 (sound from your surrounding) and adding -1 (inverted noise) giving zero therefore "diluting" the noise.
The Devialet Gemini have ANC allowing you to listen at lower volume levels, good for your ears since you don't need to crank up the device volume to overcome background sounds.
JBL Reflect Aero TWS too have Active Noise Cancellation which makes either of the devices ideal for flights and rush hour travels. Each work with different noise cancellation modes, pick the mode that suits your travel or that enhances your relaxation time.
Devialet Gemini stay well in place, creating an acoustic covering that reduces your environment sounds and also prevents the device sound from leaking out at the same.
Both JBL Reflect Aero TWS, and Devialet Gemini have passive noise reduction which means that they limit ambient noise instead of actively using ANC to cancel it out.
The Devialet Gemini have a unit size of 10mm in diameter, the bigger the unit the more powerful, and can produce better bass.
A driver unit is basically a mini speaker that produces sound in the device, its 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 Devialet Gemini by 3.2mm , 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 mean that they deliver better quality sound.
The Devialet Gemini's lowest frequency is at 5Hz, low-frequency response inidcates how well an audio device generates low recognizable frequencies and if it alters the signal while at it.
JBL Reflect Aero TWS's lowest frequency is at 20Hz, this means that Devialet Gemini produce a juicier bass than the JBL Reflect Aero TWS
The Devialet Gemini's highest frequency is at 20000Hz, high-frequency response tells how well a particular audio device makes high audible frequencies and if it changes to the signal on its way through.
JBL Reflect Aero TWS's highest frequency is at 20000Hz, this implies that both devices can generate equal treble
SPL, is the pressure level of sound, in decibels, dB, Devialet Gemini's measurement is 94dB/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 something 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.
The Devialet Gemini's battery life is 6 hours, these last longer than 5 hours of listening which is considered average before recharge. A device's battery life is usually given by the manufacturer, and with longer battery life, you get to use it for longer and have to charge the device less often.
