I know lot of you have switched to Bluetooth, but I still like my corded earbud/headset. I cannot seem to locate a Mono earbud (for just one ear) so I can use it with my iPhone. All of the earbuds/headsets I can find for the iPhone are stereo with two earbuds, and I prefer not have the second earbud dangling while I am on the phone. Are there any single earbud options out there?
