I learned that your iPod headphones may be a low-quality microphone today. I plugged my headphones into my desktop’s microphone line-in jack, and talked to Roh over gtalk. I had to have the headphones practically in my mouth, but it worked. There a few sites discussing this:
Earphones and microphones are constructed on a very similiar concept, just that earphones are optimised for hearing, and microphones are optimised for recording.
Some guy even made a completely unnecessary video.
Yes, Roh, you were right. I concede. And make my previous-disbelief-turned-appreciation public for the world.
