Let’s have a look at specific models to get an idea of what’s available.
The Shure MX150 is a subminiature lavalier that’s available with a choice of cardioid or omni capsule, as well as XLR or TQG (TA4F) connectors. The XLR version includes an in-line preamp that’s actually an impedance converter; it converts the unbalanced medium-Z capsule signal to a low-Z balanced output on an XLR connector.
A multi-position tie-clip reduces cable noise by routing the cable in loops, and can be mounted horizontally or vertically. The same clip can accommodate single or dual mics.
The Audio-Technica AT831b is a directional lavalier marked by reduced feedback and suppression of background noise. It’s designed for voice and also works well as an instrument mic, especially for pickup of acoustic guitar with included guitar adapter.
An integral 80 Hz high-pass filter provides easy switching from a flat frequency response to a low-end roll-off.
The Countryman E6 Earset puts the mic element at the side of the mouth. It’s one of the company’s most popular models, offering selectable omni or directional response. The capsule and boom, available in four colors, are so tiny that they’re nearly invisible. Other features include a detachable cable and adjustable frequency response by changing protective caps.
The Point Source Audio CO-8WS is an omni earset that includes the company’s “Unbreakable Boom” that is bendable to 360 degrees, making it highly flexible in terms of placement. It can be worn over either the left or right ear, with a dual earset option enhancing flexibility/
It’s outfitted with IP57 waterproof protection as well as replaceable X-Connectors for wireless system compatibility.
The DPA d:fine 4066 is an omni headset that puts the mic at the side of the mouth. (A cardioid version is also available.) It has a detachable boom that can be positioned at either left or right.
Available in three sizes and colors, it also has a double-vent protection system and a drop stopper on the mic boom, and the materials inside the mic are water resistant. Adapters are available for most pro wireless systems and 48-volt phantom XLR.
The Audio-Technica BP894 MicroSet is a directional earset with a rotating capsule housing. It hooks behind either ear, and the included AT8464 mount converts it to a dual-ear-worn unit.
The AKG CM311 is a directional headset designed for touring applications. The proprietary Differoid (differential cardioid) design cancels sound from floor monitors, resulting in high gain-before-feedback and solid isolation.
It’s available in different versions, such as the CM311 L with a 3-pin mini XLR connecter that fits all AKG wireless belt pack transmitters.
And this is just the tip of the iceberg when it comes to choices in miniature headworn and lavalier microphones. More than a dozen manufacturers offer a variety of types, and at a wide range of price points.
