Has Active Noise Cancellation (Noise Control)
Audio Technica ATH TWX9
✓
Devialet Gemini ✓
ANC makes use of advanced kind of tech to actively cancel noise. ANC works when, it studies the sound pattern of incoming noise and inverts the soundwaves to counter it. In simple terms, it's like having +1 (sound from your surrounding) and adding -1 (inverted noise) to make 0 resulting in a reduced level of noise.
Devialet Gemini have Active Noise Cancellation allowing you to listen at lower volume levels, causing less ear fatigue since you don't have to crank up the device volume to overcome background noise.
The Audio Technica ATH TWX9 too have Active Noise Cancellation which makes both devices ideal for flights and morning travels. The Devialet Gemini and Audio Technica ATH TWX9 operate with different noise cancellation types, pick the noise cancellation type that you prefer for commute or that enhances your chill time.
Has Passive Noise Reduction

✓
Devialet Gemini ✓
The Devialet Gemini stay tightly in place, this creates a sound covering that tones down background noise well as preventing the device sound 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
Audio Technica ATH TWX9
5.8mm
Devialet Gemini 10mm
Devialet Gemini driver unit is 10mm 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 determines the loudness of the earbuds.
Audio Technica ATH TWX9 driver unit is 5.8mm in diameter,
which means that they have a smaller driver unit than that of Devialet Gemini 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 it's true that, larger drivers are capable of generating louder sound, but this does not imply that they deliver better quality sound.
Lowest Frequency
Audio Technica ATH TWX9
20Hz
Devialet Gemini 5Hz
Devialet Gemini's lowest frequency is at 5Hz, low-frequency response measures if and how well a particular audio device generates low audible frequencies and if it makes any changes to the signal while at it.
Audio Technica ATH TWX9's lowest frequency is at 20Hz, this means that
Devialet Gemini produce a juicier bass than the Audio Technica ATH TWX9
Highest Frequency
Audio Technica ATH TWX9
40000Hz
Devialet Gemini 20000Hz
The Devialet Gemini's highest frequency is at 20000Hz, high-frequency response shows how well a particular audio component makes high recognizable frequencies and if it makes any changes to the signal while at it.
Audio Technica ATH TWX9's highest frequency is at 40000Hz, this means that
Audio Technica ATH TWX9 can produce a clearer and crispier treble than the Devialet Gemini
Sound Pressure Level
Audio Technica ATH TWX9
102dB/mW
Devialet Gemini 94dB/mW
The sound pressure level, is the pressure level of sound, measured 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.
Audio Technica ATH TWX9's sound pressure level measurement is 102dB/mW. The sound pressure level, a device is can be perceived differently by different people, so we need to have the means to get an objective measurement of sound level expressed in numerical terms.
