Sennheiser ME 9004 Cardioid Condenser Capsule Head
The ME 9004 is the cardioid condenser head developed for the SKM 9000 handheld, and the mechanical design matters as much as the capsule. Sennheiser suspends it on a snowflake shock mount, which is what allows a condenser this sensitive to be handed to a presenter who grips the microphone hard without the audience hearing it.
It is permanently polarized, 40 to 20,000 Hz, with pop suppression built into the basket. Sennheiser publishes two figures for sensitivity, maximum SPL and self-noise because the transmitter offers two settings, and both are listed below rather than one being chosen: 1.88 or 18.8 mV/Pa, 145 or 136 dB SPL, 31 or 19 dB(A). It uses the standard Sennheiser capsule interface, so it also fits other Sennheiser handheld transmitters.
