I have the BMC-3s from Sound Pro. They are no different from the BMC-2 in the sense that they have the same Panasonic capsules. The clips and design set them apart. I have no idea if Sound Pro mods the capsules (guessing not) but an unmoded Panasonic capsule distorts pretty easily. So they are better suited for light jazz music...low volume music...nature sounds...etc... If you want to record live loud music, you would better off going for the Sound Pro cardiod mics that are loaded with AT capsules.
