Has Active Noise Cancellation (Noise Control)
Beats Fit Pro
✓
Devialet Gemini ✓
Active noise cancellation utilises more advanced technology to actively cancel noise. ANC works when, it listens to the sound pattern outside and inside the earbud and then inverts the soundwaves to counter it. In simple terms, it's like having +1 (sound from your surrounding) then adding -1 (counter sound by the device) to make 0 hence "diluting" the noise.
Devialet Gemini have ANC enabling you to listen at lower volume levels, good for your ears since you don't have to crank up the earbuds volume to outcompete background noise.
The Beats Fit Pro too have Active Noise Cancellation which makes both earbuds ideal for plane rides and rush hour commutes. Each operate with different noise cancellation modes, pick the setting that suits your commute or that enhances your relaxation time.
Has Passive Noise Reduction
Beats Fit Pro
✓
Devialet Gemini ✓
Devialet Gemini stay tightly in place, creating a sound covering that reduces your environment noise and also prevents the earbuds sound from leaking out .
Both Beats Fit Pro, and Devialet Gemini have passive noise reduction this means that both tone down ambient noise without using technology to cancel it out.
Driver Unit Size
Beats Fit Pro
9.5mm
Devialet Gemini 10mm
Devialet Gemini driver unit is 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 device, the unit size determines the loudness of the earbuds.
Beats Fit Pro driver unit is 9.5mm in diameter,
which means that they have a smaller driver unit than that of Devialet Gemini by 0.5mm
, many people have a misconception that driver units of a bigger size automatically produce better sound quality.
However, large drivers usually have difficulty producing high frequencies so yes, larger drivers are capable of generating louder sound, but this does not imply that they deliver better quality sound.
Lowest Frequency
Beats Fit Pro
20Hz
Devialet Gemini 5Hz
The Devialet Gemini's lowest frequency is at 5Hz, low-frequency response measures if and how well an audio device produces low audible frequencies and if it makes any changes to the signal while at it.
Beats Fit Pro's lowest frequency is at 20Hz, this means that
Devialet Gemini can make sound with a juicier bass than the Beats Fit Pro
Highest Frequency
Beats Fit Pro
20000Hz
Devialet Gemini 20000Hz
Devialet Gemini's highest frequency is at 20000Hz, high-frequency response measures if and how well a particular audio component generates high recognizable frequencies and if it makes any adjustments to the signal on its way through.
Beats Fit Pro's highest frequency is at 20000Hz, this implies that
both devices generate equal treble
Sound Pressure Level
Beats Fit Pro
101.3dB/mW
Devialet Gemini 94dB/mW
SPL, is the level of pressure 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.
Beats Fit Pro's sound pressure level measurement is 101.3dB/mW. The sound pressure level, a device is can be taken differently by different people, so we need to have the means to get a standard measurement of sound level expressed in numerical terms.
Has A Neodymium Magnet
Beats Fit Pro
✓
Devialet Gemini ✗
The Beats Fit Pro have neodymium magnets, if used in audio devices produce a higher sensitivity and substantial sound output using less power to do so. They can help produce music at quite a high SPL, using high magnetic flux.
