Hey guys, just bought the Shure headphone adapter with microphone for the iphone. I hooked it up to my satellite aux so i can hear callers from my factory speakers... and i talk into the mic and they can hear me. The quality on my end is exceptional, but the other end can hear themselves speak. So my question is... how can i eliminate this echo? The audio from my speakers is being picked up from the microphone... which is then being transferred back to the caller on the other end, thus echoing! Im sure someone out there has had similar experiences. Any feedback would be greatly appreciated!
