IP ratings refer to the rank of protection offered by a casing, 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, Technics EAH AZ60 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 prefer a lower weight better because lighter devices are more comfortable to carry.
Technics EAH AZ60, at 14g weigh more than the Devialet Gemini by of 6g
For a device to be true wireless it must have no cables connecting any part of the device together, Devialet Gemini are true wireless for this case since they don't have cables. This is a key difference as some wireless earbuds have cables linking the pair of earbuds .
Technics EAH AZ60 also is true wireless since it has no cables connecting the pair of earbuds .
Devialet Gemini have sweat resistance
Technics EAH AZ60's resistance to sweat makes both devices ideal for use while doing sports such as 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 Technics EAH AZ60 also have stereo speakers
ANC makes use of advanced kind of tech to reduce ambient sounds. How it works, it listens to the sound pattern of incoming noise and then generates a mirror signal to counter it. Simply put, it's like having +1 (noise) and producing -1 (inverted noise) giving 0 thus "diluting" the noise.
The Devialet Gemini have Active Noise Cancellation enabling 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 sounds.
Technics EAH AZ60 too have ANC which makes either of the devices ideal for plane rides and rush hour travels. The Devialet Gemini and Technics EAH AZ60 work with different noise cancellation modes, pick the noise cancellation type that suits your commute or that enhances your chill time.
Devialet Gemini stay tightly in place, creating a sound covering that tones down background sounds while preventing the earbuds music from leaking out .
Both Technics EAH AZ60, and Devialet Gemini have passive noise reduction this means that both tone down 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, therefor producing better bass.
The driver unit is the component that produces sound in the earbuds, its size corellates with the sound made by the device.
Technics EAH AZ60 driver unit is 8mm in diameter, which means that they have a smaller driver unit than that of Devialet Gemini by 2mm , 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 yeah, larger drivers can generate louder sound, but this does not indicate that they deliver better quality sound.
The Devialet Gemini's lowest frequency is at 5Hz, low-frequency response inidcates how well a particular audio device generates low frequencies that can be heard, and if it makes any changes to the signal while at it.
The Devialet Gemini's highest frequency is at 20000Hz, high-frequency response shows how well a particular audio device produces high audible frequencies and if it makes any adjustments to the signal on its way through.
SPL, 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.
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 more battery hours, you get to use it for longer and have to charge the device less often.
Technics EAH AZ60's battery life is more than that of Devialet Gemini by 1.5 hours . Each time you recharge your earbuds, they get a little less playing time. The effect is not noticeable at first, but over a few years, your wireless earbuds will have shorter listening time.
The battery life of the charging case is given by the vendor, and Devialet Gemini's case has a charge of 18 hours. A charging case with a longer battery life enables you to recharge your earbuds on the go several times before having to recharge the case itself.
Technics EAH AZ60's charging case has a battery life of 25 hours, more than that of Devialet Gemini by 7 hours
It takes 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.
Technics EAH AZ60 takes 2 hours to fully charge the battery, more than that of Devialet Gemini by 0.5 hours
Devialet Gemini's battery capacity is 55mAh, battery power, represents the amount of electrical energy that a battery can store.
The Devialet Gemini, the device supports wireless charging. To charge the earbuds, you simply place down on a compatible charging pad.
The Devialet Gemini have a battery level indicator, an indicator notifies you when the earbuds has a low battery. The battery indicator lights display the charging state of your device and charging case.
Technics EAH AZ60 too have a battery level indicator, these allow you to determine the charging state of your earbuds, if charged fully, or having a low battery.
Devialet Gemini have USB TYPE-C, an industry-standard connector for transmitting both data and power in a single cable.
Technics EAH AZ60 too have USB TYPE-C. This USB-C plug comes along with most current electronics.
Devialet Gemini have Bluetooth version of 5, Bluetooth is a wireless technology standard that allows data movement between devices placed in range, using short-wavelength, ultra-high frequency radio waves.
Technics EAH AZ60 has a Bluetooth version of 5.2, newer than that of Devialet Gemini . Newer versions provide faster data transfers.
Devialet Gemini have a 10meters distance connecting via Bluetooth.
Technics EAH AZ60 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. Since it uses psychoacoustic modeling, it provides better results than other codecs at the same bit rate.
Being the highest quality codec that any Bluetooth-supporting Apple product supports, the Devialet Gemini will work well with your MacBook. If you intend 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 Technics EAH AZ60 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.
The Technics EAH AZ60 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).
Devialet Gemini have 2 microphones.
The Technics EAH AZ60 microphones are 8, more than that of Devialet Gemini by 6 . More microphones result in better sound quality and enable the earbuds to filter out background sounds.
Devialet Gemini use a noise-canceling type of microphone, these microphones are intended to reduce noise from the earbuds' sound.
The Technics EAH AZ60 too use a noise-canceling microphone. Especially useful in noisy areas.
