Sony NWZ-X1051F Manual

NWZ-X1050 / X1051 / X1060 / X1061 .GB.4-141-609-11(1)

The internal microphone embedded in the headphones picks up the ambient 

noise. The player generates an antiphase sound wave against the ambient noise 

to reduce it. The Noise Canceling function can reduce the unwanted ambient 

noise especially in a vehicle such as an airplane, train, bus, etc., allowing you to 

enjoy music at a low volume.

1   The waveform of the ambient 

noise (original sound).

   The internal microphone embedded in 

the headphones picks up the ambient 
noise. Then, the Noise Canceling circuit 
analyzes the waveform of the noise.

2   The antiphase waveform 

against the noise.

   The player generates the antiphase 

waveform against the noise to 
cancel it out.

3   The composite waveform. 

Two waveforms have 

canceled each other out.

   The original waveform and antiphase 

waveform combine to cancel each 
other out, reducing the ambient 
noise.

 If the supplied headphones are not used properly, the effect of the Noise Canceling 

function may be degraded. To make the most of the function, use the correct size 

earbuds to fit your ears and insert the headphones into your ears snugly.

 The Noise Canceling function mainly reduces the ambient noise in the low frequency 

bands and has no effect against the ambient noise in the high frequency bands. It has no 

effect on some sounds.

 Do not cover the microphone part of the headphones with your hands, etc., otherwise 

the Noise Canceling function may not work.

Microphone

 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.
