Has Active Noise Cancellation (Anc)

Shure Aonic 40 ✓

Sony WH CH520 ✗

Active noise cancellation uses more advanced technology to actively counter noise. How it works, it listens to the sound pattern outside and inside the earbud and then inverts the soundwaves to cancel it out. In simple terms, it's like taking +1 outside (noise from your surrounding) and adding -1 inside (counter sound within the device) to make zero hence "diluting" the noise.

Shure Aonic 40 allow you to listen at lower volume levels, causing less ear fatigue as you don't have to crank up the volume to overcome background noise.

Has Passive Noise Reduction

Shure Aonic 40 ✓

Sony WH CH520 ✓

Passive Noise Cancellation uses well-designed ear cups to seal out environment noise.

The Sony WH CH520 sits tightly in place, creating an acoustic seal that reduces background noise and prevents your music from leaking out.

Both of these devices have passive noise reduction which means that also the Shure Aonic 40 isolates you from ambient noise instead of actively using technology to cancel it out.
