Slide the noise canceling switch to the AI NC side.

When the unit is on, keep the noise canceling switch to the AI NC side until beep sounds come from the headphones. The unit starts analyzing ambient sound components (approx. 3 seconds).

During analysis, sound volume from the headphones is lowered and the indicator blinks.

When analysis is completed, the most effective noise canceling mode is set automatically, and sound volume from the headphones returns to the normal.

Noise canceling mode types

Earbuds

The M size earbuds are attached to the headphones before shipment.

If the earbuds do not fit your ears correctly, the noise canceling effect will not be optimal. To optimize noise canceling and to enjoy better sound quality, change the earbuds to another size, or adjust the earbuds position to fit your ears comfortably and snugly.
