Sennheiser ME 67
A supercardioid capsule built to screw onto a K 6 body. It is the front half of a modular mic system from Sennheiser.
Overview
The ME 67 is not a complete microphone. It's a screw-on capsule head that only works once it's mated to a Sennheiser K 6 or K 6 P powering module. On its own it's a metal-and-mesh object with no output stage, no battery compartment, and no connector. Sennheiser calls it a microphone head, and it threads onto the K 6 / K 6 P bodies as well as the MZH 30xx series mounts.
Per Sennheiser's documentation, the head has a supercardioid pattern and a frequency response of 40 Hz to 20 kHz. Those two numbers are the entire official spec sheet. A supercardioid is tighter than a cardioid and rejects more off-axis energy, which is why the pattern shows up on boom poles and in rooms where you're trying to isolate one voice from a noisy background. The 40 Hz bottom is lower than most people expect from a small capsule, and the 20 kHz top is the standard ceiling of the audible band. Sennheiser's manual for the ME 67 is printed in Germany, publication 12/06, and it confirms the same figures in six languages. It also carries a few specs the fact sheet doesn't: a free-field no-load sensitivity of 50 mV/Pa ± 2.5 dB, an equivalent noise level of 10 dB per DIN IEC 651 (21 dB per CCIR 468-3), and a maximum SPL of 125 dB(A) at 1 kHz for K = 1% distortion. 50 mV/Pa is a healthy output for a condenser, and 125 dB(A) before 1% distortion means it will sit in front of a snare or a trumpet without folding up.
The manual also settles a question the fact sheet leaves open, and it's a real discrepancy worth flagging. The English and French pages of the ME 67 instructions list dimensions as 221 x 22.5 mm, while the Spanish, German, Dutch, and Italian pages list 343 x 22.5 mm. Weight is consistent at 100 g across every language. The 221 mm figure is the more plausible one for a capsule head of this diameter — 343 mm would be longer than the entire K 6 body plus capsule — but the manual contradicts itself, so treat the length as unresolved. The 22.5 mm diameter and 100 g weight are consistent and can be relied on.
A period review of the K 6 system in Studio Sound (April 1994, p.14) shows where the ME 67 sits in the lineup. The magazine noted that Sennheiser had offered some form of modular microphone system for years, and that the K 6 series was so dedicated to the chop-and-change approach that the review set comprised a K 6-P body, an ME64 cardioid capsule, an ME62 omni, and an ME66 supercardioid (short rifle). The ME 67 is another capsule in the same family. It's a supercardioid head that shares the K 6 mount with the ME64, ME62, and ME66, so an engineer could swap it in or out of a single body depending on the job. That's also why a loose ME 67 capsule turns up on the used market without a body: owners bought into the K 6 system, accumulated capsules, and eventually split the set.
The documentation leaves a lot out. There is no production year on record, no original price, no owner reviews, and no market data. What exists is Sennheiser's own product page, the multilingual instruction sheet, and a single contemporaneous magazine mention of the broader K 6 family. Anyone shopping for an ME 67 should check the capsule's condition themselves. The mesh and diaphragm are the parts that age, and a capsule that's been rattling around in a bag without its body is a different proposition from one that's lived in a foam-lined case. The manual's foam-lined plastic case is the original storage, and it's the thing to look for.
Sennheiser confirms the pattern and the frequency response. A supercardioid head with a 40 Hz - 20 kHz range suits dialogue, close-miked instruments, and anything where you want the room pushed down and the source pushed up. The manual's 125 dB(A) ceiling and 50 mV/Pa sensitivity back that up. The exact length, the year it was introduced, and what it cost are not documented here.
