Using only one of the earphones
Pair the earphone you want to use with the Bluetooth device.
When doing this, note the following.
(
This product does not offer a function to convert stereo sound to monaural sound.
(
The L and R side function keys on the earphones work differently. For instance, you can only turn the
volume up or down when you are using one earphone. When using only one earphone, use your Bluetooth
device to operate controls like playback or talking on the phone.
