Question: Do All Headphones Work with Voice Control?
One of the ways to activate Voice Control is by using the Apple Earphones with Remote and Mic that come standard with the iPhone 3GS. But are those earphones the only earphones or headphones that can activate Voice Control?
Answer:
For now, yes. Apple will likely release an adapter for third-party headphones at some point (just as it's promised to do with the remote-enabled third-generation Shuffle headphones), but there's no telling when that might be. For now, you're required to use the Apple earphones because they're the only earphones that have the hardware built into them to activate Voice Control using clicks on the remote attached to the cord.
Luckily for those who prefer to use headphones other than Apple's earbuds, there is another way to activate Voice Control: the home button.
