Query: I recommend the Jawbone

Nothing will ever be as good as actually having your cell phone at your ear, but I think the Jawbone has been the best of 3 headsets that I've owned in the past. There's people that tell me they didn't know I was on a headset until I tell them. It blocks out background noise in my office and in my car. I'm satisfied with it.Aliph Jawbone Noise Shield Bluetooth Headset (Black)
