Ingress protection ratings is the rating of protection given by a casing, against solids and liquids. In the format of IPXX, 'X' represents a number The first value of the IP rating means protection against solids such as dust, followed by the one that refers to protection against liquids (water).
Having a value of IPX4, the Technics EAH AZ100's rating for solids indicates that no data available to specify a protection rating, and the second value of 4 means that they can withstand low pressure spray similar to that of a shower head when tilted at 180° for 10 minutes. Compared 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,
Technics EAH AZ100 has a lower liquid rating than Boult Audio Z40
Technics EAH AZ100 have a weight of 11.8g . We prefer a lower weight best for the reason that lighter devices are more comfortable to carry.
The Boult Audio Z40, at 40g
weigh more than the Technics EAH AZ100 with a difference of 28.2g
True wireless devices have no wires connecting any part of the device together, Technics EAH AZ100 are true wireless for this case since they have no cables. This is a key distinction since wireless earbuds have cables connecting the two earbuds together. Boult Audio Z40 also is true wireless since it doesn't have wires connecting the 2 earbuds together.
Technics EAH AZ100 have sweat resistance
Boult Audio Z40's resistance to sweat makes both devices ideal for use while doing sports such as long-distance running, marathons, training in workout bodysuits, 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, creating a richer sound and a better listening experience. Both Boult Audio Z40 and Technics EAH AZ100 have stereo speakers
ANC uses more advanced kind of tech to reduce unwanted ambient sounds. ANC works when, it listens to the sound pattern outside and inside the earbud and after generates a mirror signal to cancel it out.
Simply put, it's like having +1 (noise) and producing -1 (counter sound by the device) giving zero resulting in a reduced level of noise.
The Technics EAH AZ100 have ANC enabling you to listen at lower levels of volume, good for your ears as you don't have to crank up the device volume to overcome background noise. The Technics EAH AZ100 sit well in place, this creates an acoustic covering that reduces background sounds and also prevents the device music from leaking out at the same.
Both Boult Audio Z40, and Technics EAH AZ100 have passive noise reduction this implies that both tone down ambient noise without using ANC to cancel it out. The Technics EAH AZ100 have a unit size of 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 corellates with the sound produced by the device.
Boult Audio Z40 driver unit is 10mm in diameter,
making both devices similar in how loud their sound can get
, as many tend to believe that driver units of a bigger size automatically produce better sound quality.
However, large drivers find it difficult to produce 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 inidcates how well an audio device generates low recognizable frequencies and if it alters the signal while at it.
Boult Audio Z40's lowest frequency is at 20Hz, this implies that
both devices can produce equal bass
Technics EAH AZ100's highest frequency is at 40,000Hz, high-frequency response measures if and how well a particular audio device 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 implies that
Technics EAH AZ100 can produce 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 for a single charge. A device's battery life is commonly given by the manufacturer, and with longer battery life, you get to use it for longer and have to charge the device less often.
Boult Audio Z40's battery life is
less than that of Technics EAH AZ100 by 2 hours
. Every time you recharge your earbuds, they get a little less playing time. The effect is barely noticeable at first, but over a few years, your wireless earbuds will have shorter listening time. This is given by the manufacturer, and the Technics EAH AZ100'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 many times before having to recharge 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. It is highly adivsable to charge fully the battery before using the earbuds for the first time.
Boult Audio Z40 takes 1.5 hours to fully charge the battery,
less than that of Technics EAH AZ100 by 0.5 hours
Technics EAH AZ100 have a battery level indicator, an indicator alerts you when the earbuds has a low battery. The battery indicator lights show the charging state of your device and case. Technics EAH AZ100 use USB TYPE-C, an industry-standard connector for transmitting both data and power in a single cable.
Boult Audio Z40 too have USB TYPE-C. This USB-C plug comes along with most current laptops, phones, and tablets. The Technics EAH AZ100 have Bluetooth version of 5.3, Bluetooth is a wireless technology standard that allows data transfers between devices placed in range, using short-wavelength, ultra-high frequency radio waves.
Boult Audio Z40 has a Bluetooth version of 5.3,
equal to that of the Technics EAH AZ100
. Newer versions provide faster data transfers. The Technics EAH AZ100 have a 10meters distance to connect 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 that is used for Bluetooth audio.
It supports 24-bit audio at 250kbps. Because it uses psychoacoustic modeling, it can provide 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 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 Boult Audio Z40 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.
Technics EAH AZ100 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 can reach a high bitrate of 990kbps, providing high-resolution audio. The Technics EAH AZ100 have a noise-canceling microphone, these microphones are made to filter out noise from the earbuds' sound.
The Technics EAH AZ100 support ambient sound mode, which uses microphones to pass through ambient sound so that they can still be heard even when wearing the earbuds
