Breakaway is a utility that will pause/resume iTunes for you whenever you unplug and/or plug in your headphones. You can now walk away from your computer for a moment without missing a beat of your favorite song, or disturbing anyone with your speakers coming on.
Optionally, you can enable mute button functionality, which makes your mute button act as a pause for iTunes. Need to take a call? Hit mute on your keyboard and talk all you need. As soon as you unmute, iTunes will resume once more.
Note: If you want to use Breakaway solely for mute button functionality, be sure to disable "Headphones mode"
Also, Breakaway now supports Growl notifications, so you can get the status of your jack without the trouble of using a menu item.
BALTHAMOS There are a few problems with the localizations at the moment, but they are getting resolved as we speak. A small localization/UI release will be coming ASAP. Sorry for the inconvenience. (Version 1.6)
TERENOVO I downloaded Breakaway 1.5, but none of my unarchive utilities could unzip it. I got error messages saying that it could not be unzipped to due to a problem with the compression or something. (Version 1.5)
NEKO-CHAN this is great. one thing i love about my ipod nano is that it pauses if the headphones get unplugged. thanks to this app, that little detail carries over to my macbook. something like this should've came with leopard. (Version 1.3)
BILLIFER I love Breakaway. For the price (i.e., free), it doesn't matter to me whether it pauses VLC or MPlayer. The developer would likely welcome help in coding these, as well, just guessing, even though the source code isn't available at the Breakaway web site. (Version 1.0)
