I hear my voice echo some of the time (no particular relation to location) when I talk to someone. Why and how do I get it fixed? Thanks

iPhones have 2 microphones.
One is for feedback.
Try it without your case

Unpair and repair your headset.

You can try adjusting the volume and see if any results. Try to verify if it is a hardware defect by using a Bluetooth piece and if you get better results.

I found this on the Turtle Beach website: _________________________________________
If you or other players hear echoes in Live Chat:
Does it happen if you use the Microsoft communicator? Mute the microphone on your headset. Does the echoing stop? In the Xbox Dashboard > Settings > Live, set the voice to Play Through Both and unplug the talkback-controller cable. Does the echoing stop?
Echoing can sometimes be caused by high latency ("lag") on your internet connection. This may come and go depending on how much bandwidth is being used in your area.
If your talkback-controller cable's plug gets dirty, this can also cause echoing or static. Also check the input jack on the controller and make sure no foreign objects are in there.
Read these links for more advice:
Echoing can be caused by "a poor connection between the headset and the controller." http://support.microsoft.com/kb/912493 "The most likely cause is either a plug that isn't pushed all the way in, or gunk on the plug." http://xboxelle.spaces.live.com/Blog/cns!1pUP4M-J1d781v7Ac0Ta8FDw!158.entry "If you hear echo, then... someone in the chat session... needs to clean off their metal headset plug." http://majornelson.com/archive/2005/12/25/get-rid-of-voice-echo.aspx

Thanks for the opportunity to help with your problem. If you also have voice mail through your phone service provider, it's possible that while you are on the phone, the incoming call is "waiting" (meaning you are hearing a beep while you are still talking assuming you have call waiting). If you don't pick up the incoming call, your caller will hear your "voice mail" message and leave a message. However, your answering machine will not indicate that you have a message.

If my assistance was of any benefit whatsoever, please give me a rating so I can continue to improve my service. Thanks for using FixYa.com.

Did the location change, a Echo from a wall or vibration from the table. It is a one way sound, someone talks and you hear. As soon as you talk it cuts out the speaker even if they are still talking and it transmitts what you say. So any noise in the room could trigger the the transmit mode even an echo from the sound being turned up too loud. The mike is on the bottom of the base and can pick up table vibration and send it into transmit mode. So the person talking cuts in and out.
