Control iTunes and QuickTime with your iPhone Earbuds
This is a very cool feature I had no idea existed but accidentally stumbled across while on a recent flight. If you have an iPhone, you probably know that the earbuds included with it have a button to adjust volume and what not, well guess what, you can control the volume level in iTunes and QuickTime with the iPhone Earbud buttons as well! This works at least on the Unibody MacBook Pro’s, but I’m not sure if it works on the Unibody MacBook. Just plug in the iPhone earbuds to your Mac and launch QuickTime or iTunes to test it out yourself.
It’s also worth mentioning that the iPhone earbuds microphone works fine with Mac OS X too, and it makes a significantly better microphone than the one that is built in. This is particularly handy for VOIP calls through iChat, Google Voice, and Skype.
