Best Bluetooth headset for under $50?

I have a Blue Parrot XT something. It's a real headset but with one over the ear piece and a boom mic. Love it! It's expensive ($125 on sale at a truck stop). I recommend it if you can afford it or you can get a better price. The noise cancelling was superb!

I previously had a $65 Cobra that fit inside one ear. The sound was ok but nobody could hear what I said, the noise cancelling was so poor.
