Thanks for your reply. I'm waiting for Klipsch feedback. I don't understand why it's working fine with my 3Gs and not at all with all 4S. Martin

Hi all, I've discovered a big issue with my x10i : - With my former iPhone 3GS => works perfectly - I recently get an iPhone 4s ==> Not working! : When I'm calling someone (or receive a call) I have a huge echo (everytime)! Basically I hear every noise around me. It's very disturbing... I put back my x10i in my former 3Gs => works fine. Works fine also with apple headset. - I made tests with another 4S ==> same echo! Question : do the x10i is iPhone 4S compliant?? Do anyone have also this issue?? What can I do??
