Ingress protection ratings refer to the rank of protection given by an enclosure, against solids and liquids. In the format of IPXX, 'X' represents a number The first value represents protection against solids such as dust, while the second refers to resistance against liquids (water).
Having a value of IPX4, the Devialet Gemini's rating for solids indicates 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.
Compared to the Devialet Gemini, Sony WF 1000XM4 have a rating of IPX4 meaning that we are not yet certain of their rating with solids (dust) and that of liquids is that, they both have the same rating against liquids
Devialet Gemini have a weight of 8g . We take in account a lower weight best for the reason that lighter devices are easier to carry.
Sony WF 1000XM4, at 7.1g weigh less than the Devialet Gemini by -0.9g
For a device to be true wireless it must have no wires linking any part of the device together, Devialet Gemini are true wireless for this matter since they have no cables. This is a major difference as some wireless earbuds have wires linking the 2 earbuds .
Sony WF 1000XM4 also is true wireless because it has no wires linking the pair of earbuds together.
Devialet Gemini have sweat resistance
Sony WF 1000XM4's resistance to sweat makes both devices good for use during long-distance running, marathons, cardio sweat workouts , etc
An earbud foam is made to be ultracompact and lightweight, with almost no interference with earrings, spectacles, hats, or hairstyles. The Sony WF 1000XM4 have an earbud foam to some it is more comfortable than the in-ear foam.
Devialet Gemini have stereo speakers, devices with stereo speakers deliver sound from separate channels on both left and right sides, this creates a richer sound and a better listening experience.
Both Sony WF 1000XM4 and Devialet Gemini have stereo speakers
ANC utilises advanced technology to actively counter noise. ANC works when, it detects and analyzes the sound pattern outside and inside the earbud and generates a mirror signal to counter it. Simply put, it's like having +1 (sound from your surrounding) then producing -1 (counter sound by the device) to make 0 which results in a reduced level of noise.
The Devialet Gemini have ANC allowing you to listen at lower levels of volume, good for your ears since you don't have to crank up the earbuds volume to overcome background noise.
Sony WF 1000XM4 too have ANC which makes both earbuds ideal for flights and rush hour commutes. The Devialet Gemini and Sony WF 1000XM4 work with different noise cancellation settings, pick the setting that you prefer for commute or that suites your chill time.
The Devialet Gemini stay well in place, this creates an acoustic seal that reduces your environment sounds well as preventing the earbuds voice audio from leaking out .
Both Sony WF 1000XM4, and Devialet Gemini have passive noise reduction which implies that both limit ambient noise without using technology to cancel it out.
Devialet Gemini have a unit size of 10mm in diameter, the bigger the unit the more powerful, and can produce better bass.
A driver unit is basically a mini speaker that produces sound in the device, the unit size determines the loudness of the device.
Sony WF 1000XM4 driver unit is 6mm in diameter, which implies that they have a smaller driver unit than that of Devialet Gemini by 4mm , 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 mean that they produce better quality sound.
The Devialet Gemini's lowest frequency is at 5Hz, low-frequency response measures if and how well an audio device generates low frequencies that can be heard, and if it alters the signal on its way through.
Sony WF 1000XM4's lowest frequency is at 20Hz, this implies that Devialet Gemini can produce a juicier bass than the Sony WF 1000XM4
The Devialet Gemini's highest frequency is at 20000Hz, high-frequency response tells how well a particular audio component makes high recognizable frequencies and if it adjustments to the signal on its way through.
Sony WF 1000XM4's highest frequency is at 40000Hz, this means that Sony WF 1000XM4 generate a clearer and crispier treble than the Devialet Gemini
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.
Sony WF 1000XM4's sound pressure level measurement is 105dB/mW. The sound pressure level, something is can be perceived differently by different people, so we need to have a way of getting an objective measurement of sound level expressed in numerical terms.
The Sony WF 1000XM4 have neodymium magnets, if used in earbuds produce a higher sensitivity and substantial sound output while using less power. They can help produce music at quite a high sound pressure level, with the use of high magnetic flux.
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 usually given by the manufacturer, and with more battery hours, you get to use it for longer and have to charge the device less often.
Sony WF 1000XM4's battery life is more than that of Devialet Gemini by 2 hours . Every time you recharge your device, they get a little less playing time. The effect is barely noticeable at first, but over time, your wireless earbuds will have shorter listening time.
This is given by the vendor, and Devialet Gemini's case is said to have a full charge of 18 hours. A charging case with more battery hours enables you to recharge your earbuds on the go multiple times before recharging the case itself.
Sony WF 1000XM4'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 fully charge the battery before using the earbuds when they have been unused for long periods.
Sony WF 1000XM4 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 store.
