MIne dont work either .I have a pair of ultimate ears plug in ( non blue tooth)earbuds. The cable contains the basic microphone module that is "in line" on most all of the earbuds designed for telephone /communications etc...
The microphone wont work on my iphone w/ OS 7..
The apple store associate says that its a glitsch in OS 7 software and will be corrected in a future upgrade.
Apple tech support person reached via apple support line said "we dont support third party devices.."
Everyone knows apple supplied plug in earbuds w/ mirophone are uncomfortable and many people have anatomical issues with their ears which make these ( and most otehrs) unusuable. Not to mention the poor-average audio quality for music. It would be sad if apple coud not support even a basic pair of aftermarket earbuds w/microphone. They have been around forever and are a basic, universally used accessory. Anyone know anything?
