The AK UW100 uses best-in-class Passive Noise Isolation (PNI) to immerse you completely in the music.

ANC is not essential to reduce ambient noise and increase musical focus. When combined with the thoroughly tried-and-tested ergonomic design of the AK UW100, PNI is sufficient to reduce noise physically. Unlike generic ANC, which concentrates on canceling low-frequency noise, PNI can efficiently cancel unwanted ambient noise in the mid and high ranges, as well as higher-pitched sounds. Notably, the AK UW100’s noise canceling capability is comparable to ANC's, even for low frequencies. Another significant feature is that sound quality is retained since noise is attenuated by the structure of the earbuds rather than by software. Developed with the help of countless simulations, the AK UW100's best-in-class PNI capability allows you to escape annoying ambient noise and to immerse yourself in an experience where only you and the artist exist. If you wish to hear ambient sounds, just tap the left earbud once to activate ambient mode. You can switch between the four ambient modes by tapping or using the app.
