MacMost: Making the most of your Mac, iPhone, iPod, and Apple TV.

With the new iPhone 3GS’ ability to record video comes the question: can you use an external mic? The answer is yes. In fact, the earbuds that come with the iPhone 3GS have such a mic on them. But that can be inconvenient to use. A product like the Monster iMicrophone gives you a stand-alone clip-on mic and the ability to then plug in your own headphones. The mic also includes a pause button like the iPhone’s earbuds, but no volume control. So these make a good clip-on mic as well as a way to get the mic and pause button while using your own headphones.
