Dynamic vs. Electret — Which Variant?

Dynamic (Amped)

~150Ω dynamic microphone — requires amplification circuit in the adapter

Headsets: Peltor COMTAC, Ops-Core AMP, MSA Sordin MIL, OTTO NoizeBarrier, Earmor M31/M32

Electret

~2kΩ electret microphone — no amplification needed

Headsets: 3M Peltor LiteCom, commercial/LE electret headsets

Wrong impedance = no transmit audio. Dynamic mics on an electret adapter produce barely audible or silent transmissions. When in doubt, choose Dynamic — most tactical headsets are dynamic.
