Ingress protection ratings is the rank of protection offered by a casing, against dust and water. The letters 'IP' are followed by two values The first value means protection against solids such as dust, while the second refers to resistance against liquids (sweat).
Scoring IPX4, the Devialet Gemini's rating is read as, the first value of X denotes that no data available to specify a protection rating, and the second value of 4 means that they can withstand low pressure spray similar to that of a shower head when tilted at 180° for 10 minutes.
Compared to the Devialet Gemini, JEET W1S have a rating of IPX5 meaning that we are not yet certain of their rating with solids (dust) and that of liquids is that, Devialet Gemini has a lower liquid rating than JEET W1S
The Devialet Gemini have a weight of 8g . We prefer a lower weight better because lighter devices are more comfortable to carry.
The JEET W1S, at 18g are heavier than the Devialet Gemini by of 10g
True wireless devices have no cables linking any part of the device together, Devialet Gemini are true wireless for this case since they don't have cables. This is a major difference as some wireless earbuds have cables connecting the 2 earbuds together.
JEET W1S have wingtips, these are commonly used for earbuds for workouts and come as an optional add-on to the separate silicone ear tip for a better fit.
Devialet Gemini have sweat resistance
JEET W1S's resistance to sweat makes both devices ideal for use during long-distance running, marathons, training in workout bodysuits, etc
Devialet Gemini have stereo speakers, devices with stereo speakers deliver sound from separate channels on both left and right sides, creating a richer sound and a better listening experience.
The JEET W1S also have stereo speakers
Active noise cancellation makes use of more advanced technology to actively cancel noise. How it works, it listens to the sound pattern of incoming noise and after inverts the soundwaves to counter it. In simple terms, it's like taking +1 (sound from your surrounding) then producing -1 (inverted noise) to make 0 therefore "diluting" the noise.
Devialet Gemini have Active Noise Cancellation allowing you to listen at lower levels of volume, causing less ear fatigue since you don't have to crank up the device volume to outcompete background noise.
The Devialet Gemini sit well in place, creating an acoustic seal that reduces your environment noise and also prevents the device sound from leaking out .
Both JEET W1S, and Devialet Gemini have passive noise reduction which implies that they reduce ambient noise instead of actively using ANC to cancel it out.
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 makes sound in the earbuds, the unit size corellates with the loudness of the device.
JEET W1S driver unit is 11mm in diameter, making them have a larger driver unit than that of Devialet Gemini by 1mm , as many tend to believe 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 can generate louder sound, but this does not indicate that they produce better quality sound.
The Devialet Gemini's lowest frequency is at 5Hz, low-frequency response inidcates how well an audio device produces low frequencies that can be heard, and if it makes any changes to the signal while at it.
JEET W1S's lowest frequency is at 20Hz, this means that Devialet Gemini make sound with a juicier bass than the JEET W1S
The Devialet Gemini's highest frequency is at 20,000Hz, high-frequency response shows how well a particular audio device produces high human frequencies and if it adjustments to the signal on its way through.
JEET W1S's highest frequency is at 20,000Hz, this means that both devices can generate equal treble
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.
JEET W1S's sound pressure level measurement is 93dB/mW. The sound pressure level, something is can be considered differently by different people, so we need to have a way of getting an objective measurement of sound level expressed in numerical terms.
Devialet Gemini's battery life is 6 hours, these last longer than 5 hours of listening which is considered average before recharge. A device's battery life is given by the manufacturer, and with more battery hours, you get to use it for longer and have to charge the device less often.
JEET W1S's battery life is more than that of Devialet Gemini by 5 hours . Each time you recharge your device, they get a little less listening time. The effect is not noticeable at first, but over a few years, your wireless earbuds will have shorter listening time.
This is given by the manufacturer, and the Devialet Gemini's case is said to have a charge of 18 hours. A charging case with a longer battery life enables you to recharge your earbuds on the go multiple times before recharging the case itself.
It requires 1.5 hours to fully charge the Devialet Gemini's battery. It is recommended to charge fully the battery before using the earbuds for the first time.
Devialet Gemini's battery power is 55mAh, battery power, represents the amount of electrical energy that a battery can keep.
Devialet Gemini, the device supports wireless charging. To charge the earbuds, you simply put down on a compatible charging pad.
Devialet Gemini have a battery level indicator, an indicator shows you when the earbuds has a low battery. The battery indicator lights show the charging state of your earbuds and case.
JEET W1S too have a battery level indicator, charging indicators allow you to tell the charging state of your earbuds, whether fully charged, or the battery is running low.
The Devialet Gemini use USB TYPE-C, an industry-standard connector for transmitting both data and power through a single cable.
The Devialet Gemini have Bluetooth version of 5, Bluetooth is a wireless technology standard that allows data transfers between devices placed in close proximity, using short-wavelength, ultra-high frequency radio waves.
JEET W1S has a Bluetooth version of 4.1, older than that of Devialet Gemini . Newer versions provide faster data transfers.
The Devialet Gemini have a 10meters distance connecting via Bluetooth.
JEET W1S have a maximum range of 10meters, equal to that of the Devialet Gemini
Devialet Gemini support AAC, a codec used for Bluetooth audio. It supports 24-bit audio at 250kbps. Because it uses psychoacoustic modeling, it provides better results than other codecs at a similar bit rate.
Since its the highest quality codec that any Bluetooth-supporting Apple product supports, the Devialet Gemini will work fine with your iPhone. If you are planning on using these with Android you need to pay even closer attention to codec support for if they only have AAC they won't provide the best audio quality possible, ensure that they also support aptX HD, LDAC, or LHDC as well.
The JEET W1S support AAC as well. Designed to be the successor of the MP3 format, AAC generally achieves higher sound quality than MP3 encoders at the same bit rate.
JEET W1S support LDAC, a codec developed by Sony which allows streaming high-resolution audio over Bluetooth connections at up to 990 kbps at 32 bit/96 kHz. It is capable of a very high bitrate of 990kbps, providing high-resolution audio.
The Devialet Gemini support APTX Adaptive, an audio codec for Bluetooth devices that are developed by Qualcomm. It has a variable bit rate (between 279kbps and 420kbps).
JEET W1S support APTX Adaptive as well which implies that both can adjust the bit rate for different scenarios, such as listening to HD audio from other devices.
JEET W1S support APTX Low Latency, a codec developed by Qualcomm. It uses Bluetooth 5.0 technology to provide low latency audio (around 40ms), which is useful when you want to avoid audio lag for example when playing games.
The JEET W1S support APTX HD, an audio codec for Bluetooth devices that are developed by Qualcomm. It supports high-quality 24-bit audio (at a bit rate of 576kbps).
Latency refers to the time it takes for the audio signal to be transmitted to your earbuds. JEET W1S have a latency of 88ms, a lower latency reduces audio lag and is particularly important when playing games or watching videos.
