Using the call waiting function
If you receive a call while another call is already in progress, you can place the current call (call A) on hold and switch to the new call (call B).
Some of mobile phones may not be compatible with these functions.
If you receive a call while on a call, tap the touch sensor on the right or left earbud.
This places the current call (call A) on hold and switches to the new call (call B).
When the new call (call B) ends, the earbuds return to the call that is on hold (call A).

If you double tap the touch sensor on the right or left earbud while receiving a call, you can reject the call.
To return to the call that is on hold (call A)
During a call (call B), double tap the touch sensor on the right or left earbud, and then press again for approximately 2 seconds.
This ends the current call (call B) and resumes the call that is on hold (call A).
