Making a call
You can enjoy a hands-free call with a smartphone or mobile phone that supports the Bluetooth profile HFP (Hands-free
Profile) or HSP (Headset Profile), via a Bluetooth connection.
If your smartphone or mobile phone supports both HFP and HSP, set it to HFP.
Operations may vary depending on the smartphone or mobile phone. Refer to the operating instructions supplied
with your smartphone or mobile phone.
This headset supports normal incoming calls only. Calling apps for smartphones and computers are not supported.
Hint
Volume for a call can be adjusted during a telephone conversation only.
Volume during a call and volume during music playback can be adjusted independently. Changing the call volume does not
change the volume of music playback, and vice versa.
Note
Use a smartphone or mobile phone at least 50 cm away from the headset. Noise may result if the headset and the smartphone or
mobile phone are too close.
Connect the headset to a smartphone or mobile phone beforehand.

phone or by holding the
button down for about 2 seconds.
