Sony MDR-1000X 사용자 매뉴얼

Hint

When the wearing condition has been changed, such as you have changed your hair style or taken off eyeglasses, it is recommended that you
perform the Personal NC Optimizer again.

Note

When performing the Personal NC Optimizer, wear the headset in the actual use condition. Do not touch the headset while performing the
optimizer.

If the headset receives another operation while performing the Personal NC Optimizer, the optimizing is canceled.

The Personal NC Optimizer is performed only when the noise canceling function is turned on.
