The HS850, I believe, gives you a bigger bang for your buck. I was a little skeptical that it would work given the lower price. When it arrived, I charged it up, and tested it. The skepticism went away. It worked flawlessly. Voice reception is clear and it pairs well with my Samsung cell phone. This item comes in bulk packaging but otherwise is the same as the in-store item. The HS850 also comes with an ac charger only. I spent an extra 3 bucks for a car charger. Still a good deal and easy on your wallet.
