Handsfree answering (not dialing) For those who like to listen to music and ride on two wheels.[Using your hands for something other than a cell phone]. When I'm on my bike or motorcycle I can use in ear speakers [regular 3.5mm headphones] and keep the ZN4 in my shirt or jacket pocket. When a call comes in [auto answer on] music fades out to the ringer & the mic on the phone is activated (it works well enough to communicate) with headphones plugged in. Nice! When the call is over it hangs up and the music fades back in.
