I had a set of Logitech headphones/mic that connected via analog plugs. I bought them a long time ago, and decided to finally use them with a Learn to Speak Spanish program I have for Windows. When I connected them, the mic never really worked as it should. Looking up the model online, it says they're only for Windows, not Mac compatible. When I finally found some Mac headsets, they have USB plugs. Is there something with Macs that require them to use USB headphones/mics? Does this still affect them under Windows (Bootcamp)? Or were these just old and needed to be tossed years ago?
