I search but couldnt find this topic being discussed. Everybody I talked to say's when I put them on speakerphone they here this ridiculous echo, it's to the point where they cant here me talk if were doing it at the same time! I also found out when I put them on mute they tell me the echo is non existent. I have tweak my phone so I'm wondering did that have anything to do with it or is it a manufacture defect? And is anybody else experiencing this issue?
