The original question (which I quoted) mixed the two elements but the answers are still correct: the HC6 element should have no bias and the CM-500 performs as well or better than either the Proset Elite iC or Proset Elite HC6. The Proset Elite is available in two versions HC-6 ("full range dynamic broadcast element") and iC ("specially designed high performance electret condenser"). The iC element is used in all of the Heil "iC mics" including the Proset K2/K3, Proset iC, Proset Elite iC, Quiet Phone iC, BM10 iC, Handi Mic iC, and iCM . The Yamaha mic is spec'd at 100 - 20K vs. 80 - 12.5K for the iC element or 100 - 12.5K for the HC-6. In either case, the difference in specifications are insignificant and certainly don't justify 3 x the price - street prices: $44 for CM-500 (B&H Photo) vs. $149 for Proset Elite HC6 or $159 for Proset Elite iC (R & L Electronics). 73, ...
