I love audiobooks and podcasts. 90% of my commute is spent listening to one of the two. Unfortunately, the car I drive day to day doesn't have an iPhone input. In the past, I would just use the iPhone headphones and only put 1 of the buds in my ear. @nashp recently tweeted about the Jawbone ICON HD. After he ordered it and gave it the thumbs up, I decided to take the plunge.
Overall, it does what it says it does. It's an excellent bluetooth headset that sounds great when playing media. It's not as good as a wired headphone, but it's 80-90% in my opinion. It also works pretty well with Siri (again 80-90% as well as wired headphones). It comes with a wall charger and multiple ear molds. If you want a way to drive hands free and listen to your music, audiobooks, and podcasts then I highly recommend the Jawbone ICON HD.
