A:AnswerYes, if you are connected to the headphones and a call comes in you will hear it on the headphones, all you need to do is press the middle (pause/play) button once to answer it then press it once to hang up.
A:AnswerThe Bluetooth connection is thru the piece where the mic and volume buttons are located. If you use the headphones around the back of the neck it'll be against your head, just below or behind the ears depending on how you had the earbuds.
