You can use the center button (between the volume up (+) and volume down (-) buttons) on the mic portion of your headphones to perform some useful functions without taking your iOS device from your pocket.
If you use headphones with your iPhone, iPad or iPod touch then you will find these tips quite handy.
Here are 10 cool things you can do with the buttons on your headphones (some of you may already know them):
1. Activate Siri
iPhone 4S users can activate Siri by pressing and holding the center button.
2. Take a Photo
Launch the Camera app and press the volume-up (+) button on the headphone to take a photo. (This feature is available in iOS 5 or later)
3. Pause/Play a Song or Video
You can pause or play a song or video by pressing the center button.
4. Skip to the Next Song or Chapter
To skip the next song or chapter, press the center button twice quickly.
5. Go to Previous Song or Chapter
To go back to the previous song, press the center button thrice quickly.
6. Fast Forward a Song
To fast forward a song, press the center button twice and hold the center button on the second press.
7. Rewind a Song
To rewind a song, press the center button thrice and hold the center down on the third press.
8. Answer a Call or Hang up
If you get a call, press the center button to answer it and press it again to hang up.
9. Decline Incoming Call
To decline an incoming call, press the center button and hold for approximately two seconds. You should hear two beeps, which confirms that the caller was sent to voicemail.
10. Switch Calls
If you get a new call when you’re on the phone, press the center button once to switch calls. To end that new call, press and hold the center button down for 2 seconds.
Please note that these tricks should work with any headphones that include a remote or have a remote adapter. These tricks should also work on your iPad and iPod touch (except activating Siri).
