Terrible feedback with klipsch and iPhone

[rasher]

I just tested two pairs of klipsch s4i on an iPhone 4. Both sets amplified background noise which negates the noise isolating effect. I could hear the television just as loud as I had no earphones in my ears. This feedback happens during phone calls only. I put down my coffee mug on the table and it sounded like i slammed it down. I can hear myself type during a call as if the keyboard was beside my ear. I bought these based on reviews on sound quality and the fact that I travel and frequently make calls when driving and in the airport. I would not be able to hear the caller speak over the background amplified noise. The stock iPhone earbuds do not have this issue. Has anybody else had a similar experience? I tried the the s4i on an android phone and did not get the same feedback. I looked for a setting on the iPhone which would relate to this issue, like 'block/accept background noise' so people could still hear what is happening in their surroundings like an approaching car. I didn't find any such settings on the iPhone. Whe I make a call I want to isolate the caller and hear them clearly, unfortunately this is not the case.

Perhaps the mic volume is set too high so when a call comes in it is picking up everything and making it even louder.  Try turning down the mic volume.  This is done with the headphones plugged in and using the volume controls on the side.  You should see the volume icon appear on the screen when you adjust it.  Also double check that when a call comes in that the audio is not also playing through the built in speaker.
