Ingress protection ratings refer to the rating of protection offered by a casing, against dust and liquids. In the format of IPXX, 'X' represents a number The first value refers to protection against solids such as dust, while the second refers to resistance against liquids (sweat).
Scoring IPX4, the Technics EAH AZ80'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. In comparison to the Technics EAH AZ80, 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
Technics EAH AZ80 have a weight of 14g . We prefer a lower weight better because lighter devices are more comfortable to transport.
The Sony WF 1000XM4, at 7.1g
weigh less than the Technics EAH AZ80 with a difference -6.9g
For a device to be true wireless it should have no wires linking any part of the device together, Technics EAH AZ80 are true wireless for this case since they don't have wires. This is a major difference since wireless earbuds have wires linking the two earbuds .
Sony WF 1000XM4 also is true wireless because it has no wires linking the pair of earbuds together. Technics EAH AZ80 are resistant to sweat
Sony WF 1000XM4's resistance to sweat makes both devices fit for use during long-distance running, marathons, training in workout bodysuits, etc
Technics EAH AZ80 have stereo speakers, what this means is that Technics EAH AZ80's speakers deliver sound from independent channels on both left and right sides, creating a richer sound and a better listening experience.
Both Sony WF 1000XM4 and Technics EAH AZ80 have stereo speakers
Active noise cancellation uses more advanced kind of tech to actively cancel noise. ANC works when, it listens to the sound pattern of incoming noise and after inverts the soundwaves to cancel it out. Simply put, it's like taking +1 (noise) then adding -1 (counter sound by the device) giving 0 resulting in a reduced level of noise.
The Technics EAH AZ80 have ANC allowing you to listen at lower levels of volume, good for your ears as you don't have to crank up the device volume to outcompete background noise. The Sony WF 1000XM4 too have ANC making either of the earbuds ideal for plane rides and rush hour commutes. The Technics EAH AZ80 and Sony WF 1000XM4 work with different noise cancellation settings, pick the mode that you prefer for commute or that suites your chill time.
The Technics EAH AZ80 stay well in place, creating an acoustic covering that tones down background sounds and also prevents the earbuds sound from leaking out .

The Technics EAH AZ80 driver unit is 10mm in diameter, the bigger the unit the more powerful, and can produce better bass. The driver unit is the component that makes sound in the earbuds, its size corellates with 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 Technics EAH AZ80 by 4mm
, many people have a misconception 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 imply that they deliver better quality sound. The Technics EAH AZ80's lowest frequency is at 20Hz, low-frequency response measures if and how well a particular audio device produces low recognizable frequencies and if it makes any changes to the signal on its way through.
Sony WF 1000XM4's lowest frequency is at 20Hz, this means that
both devices can produce equal bass
The Technics EAH AZ80's highest frequency is at 40,000Hz, high-frequency response shows how well an audio component makes high audible frequencies and if it adjustments to the signal while at it. Sony WF 1000XM4's highest frequency is at 40,000Hz, this means that
both devices generate equal treble
Technics EAH AZ80's battery life is 7.5 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 requires fewer chargings.
Sony WF 1000XM4's battery life is
more than that of Technics EAH AZ80 by 0.5 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. This is given by the vendor, and Technics EAH AZ80's case is said to have a charge of 17.5 hours.
A charging case with more battery hours allows you to recharge your earbuds on the go many times before recharging the case itself. Sony WF 1000XM4's charging case has a battery life of 16 hours,
less than that of Technics EAH AZ80 by 1.5 hours
It requires 2 hours to fully charge the Technics EAH AZ80's battery. It is recommended to charge fully 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,
less than that of Technics EAH AZ80 by 0.5 hours
