Has Active Noise Cancellation (Noise Control)
Devialet Gemini
✓
JBL Tour Pro 2 ✓
Active noise cancellation uses advanced kind of tech to actively counter noise. How it works, it studies the sound pattern outside and inside the earbud and after generates a mirror signal to counter it. Simply put, it's like having +1 (noise) then adding -1 (inverted noise) giving 0 resulting in a reduced level of noise.
Devialet Gemini have ANC allowing you to listen at lower volume levels, good for your ears as you don't need to crank up the device volume to outcompete background sounds.
JBL Tour Pro 2 too have ANC making both earbuds ideal for flights and morning commutes. Each operate with different noise cancellation settings, pick the setting that you prefer for travel or that suites your relaxation time.

JBL Tour Pro 2 driver unit is 10mm in diameter,
making both devices similar in how loud their sound gets
, 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 it's true that, larger drivers are capable of generating louder sound, but this does not mean that they deliver better quality sound.
Lowest Frequency
Devialet Gemini
5Hz
JBL Tour Pro 2 20Hz
Devialet Gemini's lowest frequency is at 5Hz, low-frequency response measures if and how well an audio component generates low frequencies that can be heard, and if it makes any changes to the signal on its way through.

Highest Frequency
Devialet Gemini
20000Hz
JBL Tour Pro 2 20000Hz
Devialet Gemini's highest frequency is at 20000Hz, high-frequency response measures if and how well a particular audio device makes high human frequencies and if it makes any adjustments to the signal while at it.
JBL Tour Pro 2's highest frequency is at 20000Hz, this implies that
both devices produce equal treble
