Using the external sound control
The external sound control function switches between noise cancelling ( [RZ-S500W] only) ambient sound and
off. The sound quality is set so that it is optimized for each mode.
1 While wearing the earphones, touch and hold the touch sensor (R) for about 2 seconds.
• The mode is switched each time you touch and hold the touch sensor. (A guidance message will notify you of the
mode you switched to.)
[RZ-S500W]
• The default level setting is “Noise cancelling”.
[RZ-S300W]
• The default level setting is “OFF”.
2 Adjust the volume of the playback device.
∫ Noise cancelling ( [RZ-S500W] only)
Reduces the sounds (noise) you can hear from outside.
• While using the noise cancelling function, a very small amount of noise which is generated from the circuit that
reduces noise may be heard, but this is normal and not indicative of any trouble. (This very-low-level noise may be
heard in quiet places or in the blank parts between tracks.)
∫ Ambient sound
You can hear ambient sound through the microphones embedded in the earphones while enjoying music.
