Detail 01
Cardioid pattern
Rejects sound from behind, so wedge monitors placed off-axis behind you feed back less at stage volume.

CrownCM-311A Headworn Condenser Mic XLR
Independent shopping perspective
The Korena take
Head-worn cardioid condenser on a rigid ear-to-ear frame, wired XLR. For presenters, worship leaders and performers who need hands free and consistent mic distance.
Strong match
Who this is for
- Worship leaders and pastors who move while speaking or singing
- Theater and musical performers needing hands-free vocal pickup
- Fitness instructors and presenters working a room untethered
Consider the trade-offs
When to look elsewhere
- Studio vocal recording, where a large-diaphragm mic on a stand wins
- Anyone without phantom power or a wireless bodypack to feed it
- Buyers wanting deep low end; response starts at 50Hz
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
3-inch boom-to-mouth spacing
Fixed close distance keeps level steady as you turn your head, and cuts plosives compared to a mic right at the lips.
Detail 03
18V to 48V phantom power
Works off a standard console's 48V or a lower-voltage bodypack supply, so it fits both wired and wireless rigs.
Detail 04
26 dB-A self-noise
Quiet enough for spoken word on a live console. Audible hiss only if you push heavy gain in a silent room.
Detail 05
61 grams
Light enough to forget across a two-hour set; the weight sits on both ears rather than one clamped side.
Detail 06
50Hz to 17kHz response
Rolled off at the extremes, which keeps stage rumble and cymbal wash out of the vocal channel.
Final check
Know before you order
- 01Terminates in XLR — for wireless you need a bodypack adapter for your transmitter brand
- 02No wireless transmitter, receiver or windscreen budget is included in the price
- 0342-inch cable reaches a beltpack, not a stage box; plan a mic cable run
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Can I use this with my wireless bodypack?
Yes, with the right adapter. It runs on 18V to 48V phantom, which covers most bodypack supplies, but the XLR end must be converted to your transmitter's connector.
02Will it feed back on a loud stage?
The cardioid pattern rejects rear sound and the fixed 3-inch spacing keeps gain low, which helps. Monitor placement still matters — keep wedges behind and off-axis.
03Does it stay put when I move around?
It's a rigid ear-to-ear frame at 61 grams, so it braces on both ears rather than clipping to one. The boom holds its 3-inch position while you move.
04Is this the CM-311A or the CM-311L?
This is the CM-311A at 4 mV/Pa (-48 dBV). The L version is roughly 10 dB quieter output and needs more preamp gain.
