IP ratings refer to the level of protection given by a casing, against solids and liquids. The letters 'IP' are followed by two values The first value of the IP rating refers to protection against solids such as dust, followed by the one that refers to resistance against liquids (sweat).
Having a value of IPX4, the Technics EAH AZ100's rating is read as, the first number of X denotes that no data available to specify a protection rating, and the second number of 4 means 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, Boult Audio Z40 have a rating of IPX5 meaning that
we are not yet certain of their rating with solids (dust)
and that of liquids is that,
Boult Audio Z40 has a higher liquid rating than Technics EAH AZ100

weigh more than the Technics EAH AZ100 by of 28.2g
True wireless devices have no wires linking any part of the device together, Technics EAH AZ100 are true wireless for this matter since they have no cables. This is a key distinction since wireless earbuds have cables connecting the pair of earbuds .
Boult Audio Z40 also is true wireless since it has no wires connecting the 2 earbuds together. Technics EAH AZ100 are resistant to sweat
Boult Audio Z40's resistance to sweat makes both devices ideal 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 independent channels on both left and right sides, this creates a richer sound and a better listening experience.
The Boult Audio Z40 also have stereo speakers
ANC makes use of advanced technology to actively cancel noise. How it works, it studies the sound pattern outside and inside the earbud and inverts the soundwaves to counter it. Simply put, it's like taking +1 (noise) and producing -1 (inverted noise) to make zero therefore "diluting" the noise.
Technics EAH AZ100 have ANC enabling you to listen at lower volume levels, good for your ears as you don't need to crank up the device volume to outcompete background sounds. The Technics EAH AZ100 stay tightly in place, creating a sound seal that tones down background sounds and also prevents the device voice audio from leaking out .
Both Boult Audio Z40, and Technics EAH AZ100 have passive noise reduction this means that both limit ambient noise instead of actively using ANC to cancel it out. The Technics EAH AZ100 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, its size dictates the sound produced by the earbuds. Boult Audio Z40 driver unit is 10mm in diameter,
making both Boult Audio Z40, and Technics EAH AZ100 similar in how loud their sound gets
, 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 it's true that, larger drivers are capable of generating louder sound, but this does not mean that they deliver better quality sound.
Technics EAH AZ100's lowest frequency is at 20Hz, low-frequency response measures if and how well an audio component produces low frequencies that can be heard, and if it alters the signal while at it. Boult Audio Z40's lowest frequency is at 20Hz, this means that
both devices make sound with equal bass
Technics EAH AZ100's highest frequency is at 40,000Hz, high-frequency response indicates how well a particular audio component makes high audible frequencies and if it changes to the signal while at it. Boult Audio Z40's highest frequency is at 20,000Hz, this means that
Technics EAH AZ100 can generate a clearer and crispier treble than the Boult Audio Z40
The 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 commonly given by the manufacturer, and with longer battery life, you get to use it for longer and requires fewer chargings. Boult Audio Z40's battery life is
less than that of Technics EAH AZ100 by 2 hours
. Every 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 no longer play for long like they used to.
The battery life of the charging case is given by the manufacturer, and Technics EAH AZ100's case has a charge of 18 hours. A charging case with a longer battery life allows you to recharge your earbuds on the go multiple times before recharging the case itself. Boult Audio Z40's charging case has a battery life of 50 hours,
more than that of Technics EAH AZ100 by 32 hours
It takes 2 hours to fully charge the Technics EAH AZ100's battery.

equal to that of the Technics EAH AZ100
. Newer versions provide faster data transfers. Technics EAH AZ100 have a 10meters distance connecting via Bluetooth.
Boult Audio Z40 have a maximum range of 10meters,
equal to that of the Technics EAH AZ100
Technics EAH AZ100 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.
Since its the highest quality codec that any Bluetooth-supporting Apple product supports, the Technics EAH AZ100 will work well with your iPhone.
