The noise canceling function is not effective.
Make sure the noise canceling function is enabled.
The noise canceling function is available only with noise canceling headphones. The noise canceling headphones
that are compatible with this product are MDR-NW750N/MDR-NW750NE.

earbud position. If you change the size of earbuds, attach them firmly on the headphones to prevent them from
detaching and remaining in your ears.

canceling. However, you may attain more effectiveness by raising or lowering the sensitivity of the microphone built in
