I agree that the Aliph Jawbones are great. I had the original Jawbone, then I accidentally snapped the ear part off. I bought the Jawbone Prime a few months ago on Amazon for about $59. The Jawbones truly do remove the background noise. Just understand that it is the background noise around you, not around the other person you are talking to. I have talked to several people that have misunderstood. So, I can talk on the phone with my windows down on the highway and my wife can still hear me fine. Or with the radio on. It's pretty slick technology they use. They have some YouTube videos that demonstrate it.
BTW, regarding texting while driving, I see it every day. I would say that about 20% of people I drive near do that on the way to/from work. Any handheld phone activity has been a violation for a few years now in NY. I know a bunch of people who have received the $250 fine.
