Pros & Cons
👍 Pros
- Omnidirectional capsule delivers consistent frequency response regardless of head movement or speaking angle — no proximity effect coloring the voice
- Detachable dual earset clip accommodates either ear and a range of head sizes, reducing changeover time between performers
- Shure-native connector eliminates adapters and maintains impedance integrity through the signal chain
- Six included windscreens provide immediate protection against breath noise and light wind in outdoor environments
- Low-profile earworn design keeps the mic element close to the ear canal, minimizing visual presence under stage lighting
👎 Cons
- Earworn placement increases working distance from the mouth compared to cheek or hairline mounting, requiring additional transmitter and console gain
- Omnidirectional pattern offers no rejection of stage monitor bleed or ambient noise — more problematic in high-SPL live environments
- Shure-only termination limits the mic to one wireless ecosystem — not usable across a mixed-brand RF infrastructure without additional adapters
- No frequency response curve published in available product documentation, making precise EQ decisions harder without on-site measurement
Frequently Asked Questions
What wireless systems is the CO-3-KIT-SH-BE compatible with?
The CO-3-KIT-SH-BE is specifically terminated and wired for Shure wireless bodypack transmitters. It uses the correct connector pinout and impedance matching for Shure's TA4F (TQG) input. It is not cross-compatible with Sennheiser, Sony, or other wireless systems without an adapter.
What is the polar pattern of the CO-3, and how does that affect its use in live sound?
The CO-3 uses an omnidirectional polar pattern, which is standard for earworn microphones. Omni capsules have no proximity effect, so the frequency response stays consistent regardless of distance from the mouth — critical for performers who move their head or speak at varying angles. In live environments, omni capsules are also less susceptible to handling and wind noise than cardioids at this placement distance.
Does the CO-3 require phantom power?
No. As a lavalier-style earworn mic operating through a wireless bodypack transmitter, the CO-3 is powered by the transmitter's internal bias voltage — typically 1–5V. Standard 48V phantom power is not applied through wireless systems and is not relevant to this mic's power requirements.
How does the CO-3's placement on the ear affect gain before feedback in a live PA situation?
Placement at the ear rather than near the mouth increases the working distance from the sound source, which means your front-of-house engineer will need to apply more gain from the transmitter and console to achieve the same SPL as a chin or cheek placement. In feedback-sensitive environments, work with your RF coordinator to optimize transmitter gain structure before the show.
What is included in the kit, and is the earpiece interchangeable between performers?
The kit includes the CO-3 mic element with detachable dual earset clip, a body clip, and six windscreens. The dual earset clip design allows it to be worn on either ear and adjusted for different head sizes, making it practical for repertory theater or multi-cast productions where mic sharing is common.
