Dear Mr. Wolaver,

the KMS105 is a supercardioid, the KMS150 a hypercardioid, i.e. just slightly more directional. Sonically, they hold the same capsule, so there is not much difference.

If you should need a 10 dB attenuation switch, and a switchable low cut for distant / close miked situations, the KMS150 would be the first choice.

But generally, I do recommend the KMS105 for almost all applications.
