Wireless Noise Canceling Stereo Headset

WH-CH720N

Using the supplied headphone cable

If you use the headset at a place where it is restricted to use Bluetooth devices such as on an airplane, you can use the

headset as noise canceling headphones while the headset is connected to a device via the supplied headphone cable

and the headset is turned on.

Hint

You can listen to music even if the headset is turned off. In this case, the noise canceling function cannot be used.

To use the noise canceling function/Ambient Sound Mode, turn the headset on.

The headset turns off automatically if you disconnect the supplied headphone cable from the headset while it is turned on.

When an incoming call arrives, a ring tone is heard via the headset. Answer the call using your smartphone or mobile phone, and

talk using the microphone of the phone. You can hear the caller’s voice from the headset. If you disconnect the headphone cable

from the smartphone or mobile phone, you can talk using the microphone and speaker of the phone.

Note

Use the supplied headphone cable only.

Make sure that you insert the cable until it clicks. If the plug is not connected correctly, you may not hear the sound properly.

When using the headphone cable, the Bluetooth function cannot be used.

The NC/AMB (noise canceling/Ambient Sound Mode) button cannot be used when the headset is turned off.

The + (volume +)/– (volume –) and

(play/call/next/previous) buttons cannot be used. Perform operations, such as adjusting

the volume and play/pause, on the playback device.
