Overview

The Point Source Audio CO-3 is a discreet earworn microphone engineered for speech — the kind of mic you deploy when the talent needs to sound natural and present without any visible hardware drawing the audience's eye. Its omnidirectional capsule captures the full 360-degree soundfield around the speaker, which in controlled environments like houses of worship, broadcast studios, and corporate presentation rooms means you get a consistent, open-sounding signal regardless of head position. There's no directional coloration, no proximity effect, and no dead zones when the speaker glances down at notes — what you put in front of the capsule is what comes out the other end of the signal chain.

Built for Shure wireless systems with a purpose-made connector, the CO-3 integrates cleanly into established Shure BodyPack workflows without modification. The capsule is lightweight and the earworn hook positions it predictably close to the speaker's mouth, which keeps gain staging consistent across a full service or broadcast segment. The noise floor is low enough to stay transparent on quiet passages, and the voice-optimized frequency response keeps consonants clear and intelligible without sounding processed. For AV technicians managing multiple mics in a complex live environment, the CO-3's plug-and-play Shure compatibility and reliable positioning are exactly the kind of dependable, boring performance that makes for a smooth show.

Pros & Cons

👍 Pros

The omnidirectional polar pattern provides consistent, artifact-free pickup regardless of how the speaker turns their head — critical for presenters and liturgical applications where a fixed axis is unrealistic.
Lightweight earworn form factor keeps the capsule in a stable, repeatable position relative to the mouth, reducing gain-riding and level inconsistency across a long service or broadcast.
Designed specifically for Shure wireless systems, the connector integration is clean and reliable — no adapter wobble or pin-contact issues that can introduce noise in the signal chain.
Natural voice reproduction makes this mic transparent in the mix — intelligibility is high without the artificial presence bump that some headset mics use to compensate for thin capsule quality.
Discreet profile makes it appropriate for on-camera applications, corporate video, and worship contexts where visible gear would be a distraction.

👎 Cons

Omnidirectional pickup means stage monitor bleed and ambient room noise will appear in the signal — unsuitable for loud live stage environments where isolation is required.
The Shure-specific connector locks you into that transmitter ecosystem; if your facility transitions to a different wireless brand, this microphone does not transfer without purchasing a new unit or connector.
As a speech-optimized microphone, the CO-3 has a limited frequency range optimized for voice — it is not appropriate for instrument miking or any application beyond spoken-word and vocals.
No pad or high-pass filter switch means all gain staging adjustments must be made at the transmitter body, which can be inconvenient in fast-paced live production scenarios.
Earworn mounting comfort is subjective — talent with unusual ear geometry may find the hook positioning less secure, requiring repositioning between takes or segments.

Frequently Asked Questions

What gain staging approach works best with the CO-3 on a Shure wireless transmitter?

The practical starting point is to set your transmitter gain so that peaks from normal speech land around -12 to -6 dBFS at the transmitter input — the CO-3's omnidirectional capsule is voiced for speech and doesn't need heavy padding. Because it's omni, you don't get the proximity bass boost you'd expect from a cardioid, so you can trim slightly more gain from the transmitter without losing warmth in the low-mids. Trust your ears: clear consonants with no sibilance distortion is the target.

Does the omnidirectional polar pattern cause problems in live environments with stage monitors or room noise?

Omnidirectional patterns pick up sound from all directions, so stage monitor bleed and room ambience will be present in the signal. That's the trade-off you accept for the mounting freedom and consistent off-axis response an omni provides. In controlled environments — houses of worship, lectern presentations, broadcast studios — this is rarely an issue. For high-SPL live stages with close monitors, a cardioid earworn would be a better fit.

How does the CO-3 attach and stay in position during active movement?

The CO-3 uses an earworn design that hooks over the ear to hold the capsule in a consistent position near the mouth. The lightweight construction — typical of discreet presentation microphones in this class — means it stays comfortable across extended wear without fatiguing the talent. Position it with the capsule approximately at the cheekbone for the most natural pickup of forward speech.

What wireless transmitters is it compatible with beyond Shure?

The CO-3-SH-BL is specifically wired with a Shure-compatible connector. It is designed for Shure wireless transmitter bodies and is not interchangeable with TA4F (mini-XLR) connectors used by other brands without an adapter. Confirm your transmitter model is a Shure-compatible body before purchasing.

Is phantom power or any external power required for this microphone?

No separate phantom power is required — the CO-3 draws its operating power from the Shure wireless transmitter body it's connected to, as is standard for this class of earworn microphone. Battery management is handled entirely at the transmitter level.
