About 99% of the time, when I am in line, I have noise-cancelling headphones on and am listening to music. I remove them just before I get to the TDC. I never actually did this to avoid TSA, but rather the incessant prattle of people yammering on their cell phones. If I can't hear them, how can they interrogate me, at least when I am in line? So far, they have never asked me to take them off as there is usually someone lonely or friendly enough to actually chat up the BDOs and keep them busy.

I am curious how this will be handled. Or will I be deemed suspicious for having headphones on in the first place? What if I am on a cell phone, having a conversation, will they make me hang up the phone to talk to them?
