Extreme compression is too unnatural in a live setting, and subtle compression wouldn't work the peaks like I'd need. If you're a smooth singer with little change in volume and expression, it's not much of an issue, but I go from whispers to shouts, and I need more control. It's just my opinion, but I really don't like the visual of a headset on stage ... unless it was one of the teeny, hidden broadway styles that we used in my kids' musical stage productions.
