IP ratings is the rating of protection given by a casing, against dust and liquids. In the format of IPXX, 'X' represents a number The first value of the IP rating refers to protection against solids such as dust, while the second refers to resistance against liquids (sweat).
Having a value of 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 of liquids that they can withstand low pressure spray similar to that of a shower head when tilted at 180° for 10 minutes.
In comparison to the Devialet Gemini, JBL Reflect Aero TWS have a rating of IP68 meaning that they are completely dust proof and that of liquids is that, Devialet Gemini has a lower liquid rating than JBL Reflect Aero TWS
Devialet Gemini have a weight of 8g . We take in account a lower weight best for the reason that lighter devices are more comfortable to move with.
The JBL Reflect Aero TWS, at 13g are heavier than the Devialet Gemini by of 5g
True wireless devices have no wires connecting any part of the device together, Devialet Gemini are true wireless for this matter since they have no cables. This is a key difference as some wireless earbuds have cables connecting the 2 earbuds together.
JBL Reflect Aero TWS also is true wireless because it doesn't have wires connecting the two earbuds together.
The JBL Reflect Aero TWS come with wingtips, these are commonly used for earbuds for workouts and are usually an optional add-on to the separate silicone ear tip for a better fit.
Devialet Gemini have sweat resistance
JBL Reflect Aero TWS's resistance to sweat makes both devices ideal for use while doing sports such as long-distance running, marathons, training in workout bodysuits, etc
The JBL Reflect Aero TWS are both dustproof and water-resistant.
Devialet Gemini have stereo speakers, what this means is that Devialet Gemini's speakers deliver sound from independent channels on both left and right sides, creating a richer sound and a better listening experience.
Both JBL Reflect Aero TWS and Devialet Gemini have stereo speakers
Active noise cancellation makes use of more advanced kind of tech to actively cancel noise. How it works, it detects and analyzes the sound pattern of incoming noise and then inverts the soundwaves to counter it. In simple terms, it's like taking +1 (sound from your surrounding) and adding -1 (counter sound by the device) giving 0 therefore "diluting" the noise.
The Devialet Gemini have ANC enabling you to listen at lower volume levels, causing less ear fatigue as you don't need to crank up the device volume to overcome background noise.
The JBL Reflect Aero TWS too have ANC making both earbuds ideal for flights and rush hour commutes. Each work with different noise cancellation types, pick the mode that suits your commute or that enhances your chill time.
Devialet Gemini sit tightly in place, this creates an acoustic seal that reduces your environment noise and also prevents the device music from leaking out at the same.
Both of these devices have passive noise reduction this implies that both limit ambient noise instead of actively using ANC to cancel it out.
Devialet Gemini driver unit is 10mm in diameter, bigger drivers are more powerful, therefor producing better bass.
The driver unit is basically a mini speaker that makes sound in the device, the unit size dictates the loudness of the earbuds.
JBL Reflect Aero TWS driver unit is 6.8mm in diameter, which means that they have a smaller driver unit than that of Devialet Gemini by 3.2mm , 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 it's true that, larger drivers can generate louder sound, but this does not mean that they produce better quality sound.
Devialet Gemini's lowest frequency is at 5Hz, low-frequency response measures if and how well an audio component produces low frequencies that can be heard, and if it makes any changes to the signal while at it.
JBL Reflect Aero TWS's lowest frequency is at 20Hz, this means that Devialet Gemini can produce a juicier bass than the JBL Reflect Aero TWS
The Devialet Gemini's highest frequency is at 20,000Hz, high-frequency response shows how well a particular audio component produces high human frequencies and if it changes to the signal on its way through.
JBL Reflect Aero TWS's highest frequency is at 20,000Hz, this means that both devices can produce equal treble
The sound pressure level, 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.
JBL Reflect Aero TWS's sound pressure level measurement is 99dB/mW. How loud something is can be considered differently by different people, so we need to have a way of getting a standard measurement of sound level expressed in numerical terms.
The Devialet Gemini's battery life is 6 hours, these last longer than 5 hours of listening which is considered average for a single charge. A device's battery life is usually given by the manufacturer, and with longer battery life, you get to use it for longer and requires fewer chargings.
JBL Reflect Aero TWS's battery life is more than that of Devialet Gemini by 2 hours . Each time you recharge your device, they get a little less playing time. The effect is not noticeable at first, but over a few years, your wireless earbuds will no longer play for long like they used to.
This is given by the vendor, and Devialet Gemini's case is said to have a charge of 18 hours. A charging case with more battery hours allows you to recharge your earbuds on the go many times before having to recharge the case itself.
JBL Reflect Aero TWS's charging case has a battery life of 16 hours, less than that of Devialet Gemini by 2 hours
It takes 1.5 hours to fully charge the Devialet Gemini's battery. It is highly adivsable to charge fully the battery before using the earbuds when they have been in storage for long periods.
JBL Reflect Aero TWS takes 1.5 hours to fully charge the battery, equal to that of the Devialet Gemini
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 device, you just put down on a supported charging pad.
The Devialet Gemini have a battery level indicator, an indicator notifies you when the device has a low battery. Its lights show the charging state of your earbuds and case.
JBL Reflect Aero TWS too have a battery level indicator, charging indicators allow you to tell the charging state of your earbuds, whether fully charged, or having a low battery.
Devialet Gemini use USB TYPE-C, an industry-standard connector for transmitting both data and power through a single cable.
JBL Reflect Aero TWS too have USB TYPE-C. This USB-C plug is part and parcel of most current electronics.
Devialet Gemini have Bluetooth version of 5, Bluetooth is a wireless technology standard that enables data movement between devices placed in range, using short-wavelength, ultra-high frequency radio waves.

The Devialet Gemini have a 10meters distance to connect via Bluetooth.
JBL Reflect Aero TWS 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 MacBook. 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 Devialet Gemini have 2 microphones.
While the JBL Reflect Aero TWS microphones are 6, more than that of Devialet Gemini by 4 . More microphones record better sound quality and help the device to filter out noise.
The Devialet Gemini use a noise-canceling microphone, these microphones are made to filter out background sounds from the earbuds' sound.
The JBL Reflect Aero TWS too use a noise-canceling microphone. This is useful in noisy areas.
Devialet Gemini support ambient sound mode, which uses microphones to pass through ambient sound to still be heard even while wearing them
