Ingress protection ratings is the rank of protection offered by a casing, against dust and liquids. The letters 'IP' are followed by two values The first value of the IP rating means protection against solids say dust, while the second refers to resistance against liquids (sweat).
Having a value of IPX4, the Technics EAH AZ100'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. In comparison to the Technics EAH AZ100, Bose QuietComfort 2 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
Technics EAH AZ100 have a weight of 11.8g . We prefer a lower weight best because lighter devices are more comfortable to move with.
Bose QuietComfort 2, at 12.5g
are heavier than the Technics EAH AZ100 by of 0.7g
For a device to be true wireless it should have no cables linking any part of the device together, Technics EAH AZ100 are true wireless for this matter since they don't have wires. This is a key distinction since wireless earbuds have cables connecting the 2 earbuds together. Bose QuietComfort 2 also is true wireless since it has no cables linking the 2 earbuds .
Technics EAH AZ100 have sweat resistance
Bose QuietComfort 2's resistance to sweat makes both devices good for use during long-distance running, marathons, cardio sweat workouts , etc
Technics EAH AZ100 have stereo speakers, what this means is that Technics EAH AZ100's speakers deliver sound from separate channels on both left and right sides, this creates a richer sound and a better listening experience.
Both Bose QuietComfort 2 and Technics EAH AZ100 have stereo speakers
ANC uses advanced kind of tech to actively counter noise. ANC works when, it detects and analyzes the sound pattern of incoming noise and then generates a mirror signal to cancel it out. In simple terms, it's like having +1 (sound from your surrounding) and adding -1 (counter sound by the device) to make 0 hence "diluting" the noise.
The Technics EAH AZ100 have Active Noise Cancellation enabling you to listen at lower volume levels, good for your ears as you don't have to crank up the earbuds volume to outcompete background sounds. Bose QuietComfort 2 too have ANC making either of the devices ideal for plane rides and morning commutes. Each operate with different noise cancellation settings, pick the noise cancellation type that suits your commute or that enhances your chill time.
The Technics EAH AZ100 stay well in place, creating an acoustic seal that reduces your environment sounds while preventing the earbuds sound from leaking out at the same.

The Technics EAH AZ100 driver unit is 10mm in diameter, the bigger the unit the more powerful, and can produce better bass.
The driver unit is basically a mini speaker that produces sound in the earbuds, its size dictates the sound made by the device. Bose QuietComfort 2 driver unit is 9.3mm in diameter,
which means that they have a smaller driver unit than that of Technics EAH AZ100 by 0.7mm
, 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 yeah, larger drivers can generate louder sound, but this does not mean that they deliver better quality sound.
The Technics EAH AZ100's lowest frequency is at 20Hz, low-frequency response measures if and how well a particular audio component produces low frequencies that can be heard, and if it alters the signal on its way through. Bose QuietComfort 2's lowest frequency is at 20Hz, this implies that
both devices can make sound with equal bass
Technics EAH AZ100's highest frequency is at 40,000Hz, high-frequency response shows how well a particular audio component makes high recognizable frequencies and if it makes any changes to the signal while at it. Bose QuietComfort 2's highest frequency is at 20,000Hz, this implies that
Technics EAH AZ100 can produce a clearer and crispier treble than the Bose QuietComfort 2
Technics EAH AZ100's battery life is 12 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 requires fewer chargings. Bose QuietComfort 2's battery life is
less than that of Technics EAH AZ100 by 6 hours
. Each time you recharge your device, they get a little less listening time. The effect is not noticeable at first, but over time, your wireless earbuds will have shorter listening time.
The battery life of the charging case is given by the manufacturer, and the Technics EAH AZ100's case has a full charge of 18 hours. A charging case with a longer battery life enables you to recharge your earbuds on the go several times before recharging the case itself. Bose QuietComfort 2's charging case has a battery life of 18 hours,
equal to that of the Technics EAH AZ100
It requires 2 hours to fully charge the Technics EAH AZ100's battery.
It is recommended to charge fully the battery before using the earbuds when they have been unused for long periods. Bose QuietComfort 2 takes 2 hours to fully charge the battery,
equal to that of the Technics EAH AZ100
