Unplug headphones - call gone?

The microphone switch on the headset is used as an answer/end button. When you insert or remove the headset, you may short the pins together creating the same effect as if you had pressed the switch.

This could cause the phone to answer or end, or the iPod to play or pause.

It can be a random thing as sometimes you will not short the pins together. It is almost guaranteed to happen if you plug a 3-pin plug or adapter/splitter into the iPhone.

Hope this helps.

I have noticed a similar but related problem. While using the iPod function of my iPhone I removed the headphone jack while a song was playing. I expected the music to immediately be routed to the iPhones built-in speakers. Instead, the music stopped playing. Not the response I was expecting.

My experience with this issue:

1. Unplug headphones while speaking on phone, and call audio is muted without Mute button activated, THEN call automatically disconnects.

2. Dial call without headphones and call is muted without Mute button activiated. Phone call is actually placed, but call audio only works if headphones are then plugged in OR if Speaker button is pressed.

3. Plug in headphones, first song from iPhone starts playing automatically. Unplug and music continues. Plug headphones back in and music stops. Repeat and song picks up from last time played.

Could this be a short in the headphone jack?

Has this been acknowledged? My iPhone does the same thing. Once I have used my headphones for a call, after I unplug them, I can no longer be heard on calls, unless I switch to speaker, or plug back in. The position persists until I power cycle. My firmware is up-to-date.

I tried this with my phone and my call does not drop even if I answer first then pull the headphones out. I have 1.1.1 firmware not sure what you have?

Exactly. Inserting or removing the headset could even cause the effect of pressing the switch twice, which would answer and then immediately end the call. Maybe that's what you saw.
