The mics are built like tanks and are reliable and capture signals that are surprisingly accurate. Both mics have unidirectional cardioid patterns, which allow you to closely mic your sound sources with little - if any - bleed between and among the mics if they are placed close to the sources. Also, they are dynamic mics, which means they require no phantom power and can be used with an XLR cable or an XLR with a 1/4" adapter for the mixer end.
