Has Active Noise Cancellation (Noise Control)

Active noise cancellation makes use of advanced technology to actively cancel noise. ANC works when, it detects and analyzes the sound pattern of incoming noise and inverts the soundwaves to cancel it out. Simply put, it's like taking +1 (sound from your surrounding) then adding -1 (counter sound by the device) to make 0 therefore "diluting" the noise.
The Devialet Gemini have Active Noise Cancellation allowing you to listen at lower volume levels, causing less ear fatigue since you don't need to crank up the device volume to overcome background noise.
The Sennheiser Momentum True Wireless 3 too have Active Noise Cancellation which makes either of the devices ideal for flights and rush hour commutes. Each operate with different noise cancellation modes, pick the mode that you prefer for travel or that suites your relaxation time.
Has Passive Noise Reduction
Devialet Gemini
✓
Sennheiser Momentum True Wireless 3 ✓
Devialet Gemini sit tightly in place, this creates an acoustic covering that tones down your environment sounds and also prevents the device voice audio from leaking out .
Both of these devices have passive noise reduction this implies that they limit ambient noise without using technology to cancel it out.
Driver Unit Size
Devialet Gemini
10mm
Sennheiser Momentum True Wireless 3 7mm
Devialet Gemini driver unit is 10mm in diameter, the bigger the unit the more powerful, therefor producing better bass.
A driver unit is basically a mini speaker that makes sound in the earbuds, the unit size determines the sound produced by the earbuds.
Sennheiser Momentum True Wireless 3 driver unit is 7mm in diameter,
which means that they have a smaller driver unit than that of Devialet Gemini by 3mm
, 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 can generate louder sound, but this does not indicate that they produce better quality sound.
Lowest Frequency
Devialet Gemini
5Hz
Sennheiser Momentum True Wireless 3 5Hz
The Devialet Gemini's lowest frequency is at 5Hz, low-frequency response inidcates how well a particular audio component produces low frequencies that can be heard, and if it makes any changes to the signal while at it.
Sennheiser Momentum True Wireless 3's lowest frequency is at 5Hz, this means that
both devices can produce equal bass
Highest Frequency
Devialet Gemini
20000Hz
Sennheiser Momentum True Wireless 3 21000Hz
Devialet Gemini's highest frequency is at 20000Hz, high-frequency response tells how well a particular audio device produces high recognizable frequencies and if it changes to the signal on its way through.
Sennheiser Momentum True Wireless 3's highest frequency is at 21000Hz, this means that
Sennheiser Momentum True Wireless 3 can generate a clearer and crispier treble than the Devialet Gemini
Sound Pressure Level
Devialet Gemini
94dB/mW
Sennheiser Momentum True Wireless 3 107dB/mW
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.
Sennheiser Momentum True Wireless 3's sound pressure level measurement is 107dB/mW. How loud something is can be taken differently by different people, so we need to have the means to get an objective measurement of sound level expressed in numerical terms.
