Can't talk while headphones are plugged in

Hi ecwman,

Does the issue persist with another headset?
If it doesn't, there may be an issue with the headset.
If it does, there may be debris in the iPhone headphone jack. Try connecting and disconnecting the headphones a few times.

You can request repair or replacement of the iPhone Stereo Headset online here: https://selfsolve.apple.com/GetWarranty.do

Also, you can get the iPhone or headset replaced by making a reservation with a Genius or calling AppleCare.

Looks like its the headphones as an old pair I have works just fine.

The easiest way to get them replaced is to setup repair online or visit an Apple retail store, if there is one close by.

Hi, I have the same problem. Suddenly I was able to hear through my apple headphone, but couldn't speak: no one could hear me. So I replaced the headphones, but nothing changed. Then I've read that I had to reinstall the Iphone, so I did. But still not working. Any idea what could be wrong? Thanks for helping.
