This is really the complete Jabra Motion Office system. It includes both the base and the headset. From the wording on greatofferstock.com, I wasn't sure at first, and had them verify before ordering.
I wanted a headset that would work not only with my cell phone, but with my office (Voip) phone as well. This does both, and even works with the bluetooth in my PC, replacing that headset as well. It is definitely not the smallest headset, but it is very comfortable and works very well.
It automatically switches to whichever phone or pc is transmitting. That works fantastic with my cell and PC, but I did need to by a "lifter" (Jabra GN1000) in order for it to automatically answer my office phone.
This is a just released product, but greatofferstock.com not only had it, but had it cheaper than anywhere else I could find it. It shipped and arrived very quickly also.
I am very happy with both the Jabra Motion Office and Great Offer Stock.com.
