Some airplanes are louder than others. Maybe you're lucky to have a fleet of quiet airframes, but there's considerable variation in cockpit noise at my airline. I wouldn't go as far as saying I have to shout, but I do have to raise my voice when the other pilot is "topless".
You said the ANR sets cut out too much noise. What specific noises are you concerned about?
To your last point on GA sized headsets, you'll probably see them for 3 reasons:
- already owned a good headest
- the current GA headsets are quite comfortable for long periods
- being designed for louder environments, they're quieter than the "jet" headsets
