Has Active Noise Cancellation (Noise Control)
Devialet Gemini
✓
Skullcandy Indy Fuel ✗
ANC uses more advanced technology to reduce ambient sounds. ANC works when, it detects and analyzes the sound pattern of incoming noise and then generates a mirror signal to cancel it out. Simply put, it's like having +1 (sound from your surrounding) and adding -1 (inverted noise) to make zero hence "diluting" the noise.
Devialet Gemini have Active Noise Cancellation enabling you to listen at lower volume levels, good for your ears since you don't need to crank up the device volume to outcompete background sounds.
Has Passive Noise Reduction
Devialet Gemini
✓
Skullcandy Indy Fuel ✓
The Devialet Gemini stay tightly in place, creating a sound covering that tones down background sounds and also prevents the earbuds music from leaking out at the same.
Both Skullcandy Indy Fuel, and Devialet Gemini have passive noise reduction this implies that they tone down ambient noise without using technology to cancel it out.
Driver Unit Size
Devialet Gemini
10mm
Skullcandy Indy Fuel 6mm
Devialet Gemini driver unit is 10mm in diameter, the bigger the unit the more powerful, and can produce better bass.
The driver unit is the component that makes sound in the device, the unit size corellates with the sound produced by 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 find it difficult to produce high frequencies so yeah, larger drivers can generate louder sound, but this does not imply that they produce better quality sound.
Lowest Frequency
Devialet Gemini
5Hz
Skullcandy Indy Fuel 20Hz
Devialet Gemini's lowest frequency is at 5Hz, low-frequency response inidcates how well a particular audio device produces 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 means that
Devialet Gemini 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 while at it.
Skullcandy Indy Fuel's highest frequency is at 20000Hz, this means that
both devices can produce equal treble
Sound Pressure Level
Devialet Gemini
94dB/mW
Skullcandy Indy Fuel 105dB/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.
Skullcandy Indy Fuel's sound pressure level measurement is 105dB/mW. The sound pressure level, a device is can be perceived differently by separate people, so we need to have a way of getting a standard measurement of sound level expressed in numerical terms.
