✓
Technics EAH AZ60 ✓
ANC makes use of more advanced technology to reduce unwanted ambient sounds. How it works, it listens to the sound pattern of incoming noise and after inverts the soundwaves to cancel it out. In simple terms, it's like taking +1 (noise) then producing -1 (inverted noise) to make 0 which results in a reduced level of noise.
Technics EAH AZ60 have Active Noise Cancellation allowing you to listen at lower volume levels, good for your ears as you don't have to crank up the device volume to overcome background noise.
The Audio Technica ATH TWX9 too have Active Noise Cancellation which makes both devices ideal for flights and rush hour commutes. The Technics EAH AZ60 and Audio Technica ATH TWX9 work with different noise cancellation types, pick the mode that suits your travel or that suites your chill time.
