The listing, ****Verizon HandsFREE headset With Adapter****NEW has ended.
I prefer not to deal with the bluetooth technology. There is nothing worse than driving and getting a call when your cell phone and bluetooth haven't been connected yet. And who has time to connect bluetooth everytime you get in the car? And which smartphones can handle the battery drain with bluetooth on all day? This eliminates the problem without battery drain. Crystal clear sound and Extreme comfort! On off and volume with an adapter (2.5 and 3.5) it will fit most phones. I'll try to answer your questions only used it once purchased same type but newer model. Shipping is free in US. Enjoy!
