Purple Nugget, "Since I'm getting early parole on the 727, moving on to quieter jets, I'm looking at getting an in-ear molded headset."

Why? I don't know about the Bus, but very few folks use headsets on the Maddog. For the most part, it's quite enough in the cockpit to hear each other using normal, conversational volume. My advice would be to wait until after your IOE to evaluate for yourself, whether or not you'll need a headset.
