Use only one earphone
You can use just one earphone after completing initial settings and after connecting to a Bluetooth® device. For example, if you take out only earphone (R) and leave earphone (L) in the charging cradle, earphone (R) will connect to the smartphone. You can listen to music or make calls with one earphone while charging the other.
Note:
•The audio will be monaural.
•If you take out the other earphone from the charging cradle when using only one earphone, the earphones will automatically connect wirelessly and switch to using both. The audio will be stereo.
