About Noise Canceling (NWZ-E573/E574/E575 only)

1. The waveform of the ambient noise (original sound).

2. The antiphase waveform against the noise.

3. The composite waveform. Two waveforms cancel each other out.

Notes on using the Noise Canceling function

• If the supplied headphones are not used properly, the effect of the Noise Canceling function may be compromised. To make the most of the function, use the correct size earbuds to fit your ears and insert the headphones into your ears snugly.

• Rubbing noises may occur while wearing headphones. This is not a malfunction.

• The Noise Canceling function mainly reduces ambient noise in the low frequency bands and has less effect on ambient noise in the higher frequency bands, such as voices and ringing tones. It has no effect on certain sounds.

• Do not cover the microphone part of the headphones () with your hands, etc., otherwise the Noise Canceling function may not work.

• You may hear a slight noise when the Noise Canceling function is active. This is operational noise of the Noise Canceling function and not a malfunction.

• You may feel the Noise Canceling function does not work or noise is louder in a quiet environment or certain noises may not be canceled as effectively as others. In this case, release the Noise Canceling function.

• Mobile phones may cause noise. In this case, keep your Walkman away from mobile phones.

• Make sure to remove the headphones from your ears before you connect or disconnect the headphones from the headphone jack of your Walkman. If the headphones are connected or disconnected from the Walkman during playback, or while the Noise Canceling function is active, noise may be generated. This is not a malfunction.

• When the [Noise Canceling: On/Off] setting is changed, a switching sound will be generated. This sound is generated by the switch of the Noise Canceling circuit, and is not a malfunction.
