Devialet Gemini 2 Vs. Technics Eah Az80 Review In Detail

Design

Ingress Protection (Ip) Rating

Technics EAH AZ80 IPX4
Devialet Gemini 2 IPX4

Ingress protection ratings is the rating of protection given by an enclosure, against solids and liquids. The letters 'IP' are followed by two values The first value of the IP rating means protection against solids say dust, while the second refers to resistance against liquids (water).

Scoring IPX4, the Devialet Gemini 2's rating is read as, the first number of X denotes that no data available to specify a protection rating, and of liquids that they can withstand low pressure spray similar to that of a shower head when tilted at 180° for 10 minutes.

Compared to the Devialet Gemini 2, Technics EAH AZ80 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

Sound Quality

Has Active Noise Cancellation (Noise Control)

Technics EAH AZ80
Devialet Gemini 2

ANC utilises advanced kind of tech to actively counter noise. ANC works when, it listens to the sound pattern outside and inside the earbud and inverts the soundwaves to counter it. Simply put, it's like having +1 (sound from your surrounding) and producing -1 (counter sound by the device) giving 0 thus "diluting" the noise.

The Devialet Gemini 2 have ANC allowing you to listen at lower levels of volume, causing less ear fatigue as you don't need to crank up the earbuds volume to outcompete background noise.

Technics EAH AZ80 too have ANC making either of the devices ideal for plane rides and morning travels. Each operate with different noise cancellation types, pick the mode that suits your travel or that enhances your relaxation time.
