Ingress protection ratings is the rating of protection given by an enclosure, against dust and water. In the format of IPXX, 'X' represents a number The first value of the IP rating refers to protection against solids say dust, while the second refers to protection against liquids (water).
Scoring IPX4, the Technics EAH AZ80'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. Compared 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
The Technics EAH AZ80 have a weight of 14g . We consider a lower weight better because lighter devices are more comfortable to move with.
Sony WF 1000XM4, at 7.1g
weigh less than the Technics EAH AZ80 with a difference -6.9g
True wireless devices have no wires linking any part of the device together, Technics EAH AZ80 are true wireless for this matter since they don't have wires.

Both Sony WF 1000XM4 and Technics EAH AZ80 have stereo speakers
Active noise cancellation makes use of more advanced technology to reduce ambient sounds. How it works, it detects and analyzes the sound pattern outside and inside the earbud and inverts the soundwaves to counter it. In simple terms, it's like having +1 (noise) then producing -1 (counter sound by the device) giving zero hence "diluting" the noise.
Technics EAH AZ80 have Active Noise Cancellation enabling you to listen at lower volume levels, causing less ear fatigue as you don't need to crank up the device volume to overcome background noise. The Sony WF 1000XM4 too have Active Noise Cancellation which makes either of the devices ideal for flights and morning travels. The Technics EAH AZ80 and Sony WF 1000XM4 work with different noise cancellation types, pick the noise cancellation type that you prefer for travel or that enhances your chill time.

The Technics EAH AZ80 driver unit is 10mm in diameter, the bigger the unit the more powerful, therefor producing better bass. A driver unit is basically a mini speaker that produces sound in the device, the unit size determines the sound made by the device.
Sony WF 1000XM4 driver unit is 6mm in diameter,
which means that they have a smaller driver unit than that of Technics EAH AZ80 by 4mm
, 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 yes, larger drivers can generate louder sound, but this does not mean that they produce better quality sound. The Technics EAH AZ80'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 makes any changes to the signal on its way through.
Sony WF 1000XM4's lowest frequency is at 20Hz, this means that
both devices produce equal bass
Technics EAH AZ80's highest frequency is at 40,000Hz, high-frequency response tells how well a particular audio device produces high recognizable frequencies and if it changes to the signal while at it. Sony WF 1000XM4's highest frequency is at 40,000Hz, this means that
both devices produce 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 given by the manufacturer, and with longer battery life, you get to use it for longer and have to charge the device less often.
Sony WF 1000XM4's battery life is
more than that of Technics EAH AZ80 by 0.5 hours
. Each time you recharge your earbuds, they get a little less playing time. The effect is barely noticeable at first, but over time, your wireless earbuds will no longer play for long like they used to.
