What microphones have Roswellite and what do they sound like?
Right now el Diablo and Naked Eye Roswellite have Roswellite in them. The el Diablo is a unique microphone voiced somewhat like a U47fet, and with a rising response not unlike a large diaphragm condenser, but with a presumed bigger dynamic range at the bottom. The reason I say “presumed” is that we do not yet have a good test setup for measuring distortion at extreme excursions. Naked Eye Roswellite sounds very much like Naked Eye Classic, to the point where most people regard it as the same. Once again, however, the higher SPL handling of Roswellite, especially at the bottom end, should result in a bigger dynamic range than its aluminum cousin, but it is probably not very different sounding in normal use.
