Apple packs a lot of functionality into that little button on your iPhone headphones! There are plenty of posts out that cover some of the functionality, but here’s a consolidated list.
When a call is coming in (the phone is ringing)
- One click = answer or hang up the call
- Hold for 2 sec = ignore the new call (and send to voicemail)
During a call with a second call coming in (call waiting)
- One click = hold the current call and switch to the new call
- Hold for 2 sec = ignore the new call (and send to voicemail)
Outside of phone calls
- Hold for 2 sec = activate Voice Control (on 3Gs or newer models)
- One click = play or pause music
- Double click = next song
- Tripple click = go back (start of song or previous song)
- Click once then click and hold = fast forward
- Click twice then click and hold = rewind
Up & Down Buttons
- While music is playing, up & down adjust headphones music volume
- While music is stopped/paused, up & down adjust ringer volume
