Has Active Noise Cancellation (Noise Control)
Devialet Gemini
✓
Skullcandy Indy Fuel ✗
Active noise cancellation uses more advanced technology to reduce ambient sounds. How it works, it detects and analyzes the sound pattern of incoming noise and inverts the soundwaves to counter it. Simply put, it's like taking +1 (sound from your surrounding) and adding -1 (inverted noise) to make 0 resulting in a reduced level of noise.
The Devialet Gemini have ANC enabling you to listen at lower levels of volume, causing less ear fatigue since you don't need to crank up the earbuds volume to overcome background noise.
Has Passive Noise Reduction
Devialet Gemini
✓
Skullcandy Indy Fuel ✓
Devialet Gemini stay well in place, creating an acoustic covering that reduces background noise and also prevents the earbuds sound from leaking out .
Both of these devices have passive noise reduction which implies that both reduce ambient noise instead of actively using ANC to cancel it out.
Driver Unit Size
Devialet Gemini
10mm
Skullcandy Indy Fuel 6mm
The Devialet Gemini driver unit is 10mm in diameter, the bigger the unit the more powerful, and can produce better bass.
A driver unit is the component that produces sound in the device, its size corellates with the loudness of the earbuds.
Skullcandy Indy Fuel driver unit is 6mm in diameter,
which means that they have a smaller driver unit than that of Devialet Gemini by 4mm
, 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
Devialet Gemini
5Hz
Skullcandy Indy Fuel 20Hz
Devialet Gemini's lowest frequency is at 5Hz, low-frequency response measures if and how well a particular audio component generates low frequencies that can be heard, and if it alters the signal on its way through.
Skullcandy Indy Fuel's lowest frequency is at 20Hz, this implies that
Devialet Gemini can make sound with a juicier bass than the Skullcandy Indy Fuel
Highest Frequency
Devialet Gemini
20000Hz
Skullcandy Indy Fuel 20000Hz
Devialet Gemini's highest frequency is at 20000Hz, high-frequency response shows how well a particular audio component produces high audible frequencies and if it makes any changes to the signal on its way through.
Skullcandy Indy Fuel's highest frequency is at 20000Hz, this implies that
both devices generate equal treble
Sound Pressure Level
Devialet Gemini
94dB/mW
Skullcandy Indy Fuel 105dB/mW
The sound pressure level, 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.
Skullcandy Indy Fuel's sound pressure level measurement is 105dB/mW. The sound pressure level, a device is can be considered differently by separate people, so we need to have the means to get a standard measurement of sound level expressed in numerical terms.
