Voice feedback loop into the headphones Is there a way on a Mac to have the input from the microphone be played in the headphones so I can listen to my own voice? Talking when you can't listen to yourself is a bit awkward
There's always LineIn (I'm not the developer), which allows you to route audio from different inputs to different outputs as you choose.

The setup for routing audio from the microphone (or any other input source) to the speakers is as follows:



To start or stop audio routing, click the Play Thru button.
