The commonly used "broadcast mics" are the EV RE20
and the Shure SM7b
Those are what the "pros" use and there's a reason they love them.
Another very a nice announcer's mic is the Sennheiser MD421
Although not generally thought of as an "announcer's mic", the Shure SM81
(with a big foam windscreen) actually works exceptionally well as one and is used at several broadcast studios. They work equally well for male and female announcers. (phantom power required.)
Another to look at is the EV RE320
At a lower price point, but still an excellent voice mic is the EV-635A
, which is commonly used for ENG (Electronic News-Gathering).
If room acoustics are an issue and you want a mic with a narrower acceptance angle (and high rejection of room sounds and reflections), a supercardioid like a EV N/D 767a
is a wonderful sounding, very clean mic. It's designed for very close-up use with very controlled bass boost up close.
Finally, there's nothing wrong with a "lowly" SM58
, although it won't provide the bass "huskyness" that some speakers like. Another possibility is a low cost LDC like the MXL V63M condenser
. Those are nice sounding at their price point, but do require a "pop" filter
in front for voice-over use. The MXL also requires a mic input with phantom power.
Each of the above has it's own best working distance depending on your mic technique, the sound of your voice and the effect you're trying to achieve.
