I have a pair of the older ones. Say what you will, but if you have an iphone, they are incredible. Using one is great for podcasts and phone conversations. I hated on them for a while, but after trying, I'm a believer.

For me, the value of upgrading to this 'pro' model will be the quality of the noise cancelling. If as good as the recent releases from Sony and/or Bose, I will definitely get a pair.
