Wireless Noise Canceling Stereo Headset
WH-XB900N
The noise canceling effect is not sufficient.
Make sure that the noise canceling function is turned on.
Adjust the earpad position to fit your ears.
The noise canceling function is effective in low frequency ranges such as airplanes, trains, offices, near air-
conditioning, and is not as effective for higher frequencies, such as human voices.
