I have a couple of these mics. I often use them to record cars and
motorcycles when the mics need to be under the hood of a vehicle or
otherwise attached to a moving vehicle. They do look similar to the
635, but sound way, way better. The fact that they're omnis makes
them much less susceptible to wind problems than a directional mic,
and directionality isn't necessary for the kinds of applications I use
them for. Obviously when they're on a moving vehicle they still need
to be wind screened though. I've also used them in high rf situations
when condensers were acting like radios, and they've made some nice
recordings of explosions in a spaced setup on two separate stands.
Sorry, but I long since lost any data sheets I had on them.
