Question about Poly Voyager Legend

No, no USB dongle included.

Does this model have active noise reduction ?

Yes, it comes with a charger.
I am also satisfied with the thing, functionality is good (speech & hearing quality, connection to the phone), but the battery never lasts the stated 7 h. When switching on, the remaining runtime is always announced. It can happen that a battery life of 2 hours is announced and then after 20' it is over...
