A:AnswerYES, it was an additional benefit that I did not even buy the unit for.
It works via battery and turns your cell phone via blue tooth into a conference call devise so you never have to hold the phone up on speakerphone.
Highly recommended to my friends. Now, 3 more own one and LOVE it
A:AnswerYes you can connect to multiple Bluetooth at the same time and switch back and forth in between. Also, you can attach this to your PC using the USB port and even it becomes more handy if you get a call or want to listen music from your PC.
