Has Active Noise Cancellation (Noise Control)
Technics EAH AZ80
✓
JLab Go Air ✗
Active noise cancellation uses more advanced kind of tech to reduce unwanted ambient sounds. ANC works when, it studies 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 0 resulting in a reduced level of noise.
The Technics EAH AZ80 have Active Noise Cancellation allowing you to listen at lower volume levels, good for your ears as you don't need to crank up the earbuds volume to outcompete background noise.
Has Passive Noise Reduction

JLab Go Air ✓
The Technics EAH AZ80 stay well in place, creating a sound covering that tones down background sounds while preventing the earbuds voice audio from leaking out at the same.
Both of these devices have passive noise reduction which means that both tone down ambient noise instead of actively using ANC to cancel it out.
Driver Unit Size
Technics EAH AZ80
10mm
JLab Go Air 8mm
The Technics EAH AZ80 driver unit is 10mm in diameter, bigger drivers are more powerful, therefor producing better bass.
A driver unit is basically a mini speaker that produces sound in the earbuds, the unit size determines the loudness of the earbuds.
JLab Go Air driver unit is 8mm in diameter,
which means that they have a smaller driver unit than that of Technics EAH AZ80 by 2mm
, a common assumption 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 imply that they produce better quality sound.
Lowest Frequency
Technics EAH AZ80
20Hz
JLab Go Air 20Hz
Technics EAH AZ80's lowest frequency is at 20Hz, low-frequency response measures if and how well a particular audio device produces low audible frequencies and if it makes any changes to the signal while at it.
JLab Go Air's lowest frequency is at 20Hz, this means that
both devices make sound with equal bass
Highest Frequency
Technics EAH AZ80
40,000Hz
JLab Go Air 20,000Hz
The Technics EAH AZ80's highest frequency is at 40,000Hz, high-frequency response shows how well an audio component makes high human frequencies and if it changes to the signal on its way through.
JLab Go Air's highest frequency is at 20,000Hz, this implies that
Technics EAH AZ80 can produce a clearer and crispier treble than the JLab Go Air
Sound Pressure Level
Technics EAH AZ80
✗
JLab Go Air 103dB/mW
The sound pressure level, is the level of pressure of sound, in decibels, dB, JLab Go Air's measurement is 103dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
