the BCM 104 broadcast microphone has an internal pop-filter, that can be sufficient with trained speakers. The KMS stage mics have a very efficient one, but would not be your first choice for voice-over, I would say.
In any case, pop protection increases with the larger distances between mouth <> pop shield, and pop shield <> membrane. So, the safest solution is still the classical external pop-filter, with 5+ cm distances. And, personally I would avoid reflective constructions, like metal grids.
