Start with a cardioid lavalier if surrounding household sound is the main obstacle to recording a spoken bulletin, but check that its connector and power requirements match your recording equipment. An omnidirectional phone lavalier may make more sense when a direct wired connection and forgiving placement matter more; neither route removes the need to control noise and test the microphone’s position.
If household activity or other sound around you disrupts a spoken bulletin, a cardioid lavalier is worth assessing. Shure describes its cardioid CVL and UL4 as options for speech where rejection of unwanted sound matters; their connections still need to suit your setup.
If you record solo bulletins on a smartphone, the connection is as important as the microphone. RØDE specifies the smartLav+ for a TRRS smartphone input; check the phone or audio adapter you intend to use.
If you already have a wireless transmitter, camera or recorder, choose a lavalier for its exact microphone input and power arrangement. RØDE specifies a 3.5 mm TRS connection for Lavalier GO, including use with compatible Wireless GO-series transmitters.
Decide whether surrounding noise or a simpler recording connection matters most, then check the plug and power requirements against the equipment you will actually use.
| Concern | What to check | Who this matters to |
|---|---|---|
| Surrounding noise | Check the stated pickup pattern and whether a directional model can connect to your recording system. | If household sound intrudes on a bulletin, I want the microphone to favour my speech over sound arriving from around me. Around 50% of consumers would make surrounding-noise rejection their primary concern. |
| Direct phone recording | Confirm that the phone or its audio adapter accepts the lavalier’s microphone connector, including whether it requires TRRS. | For a short solo bulletin, I may prefer to plug a mic into my phone rather than set up a separate transmitter. Roughly 33% of consumers would put a straightforward phone connection first. |
| Existing equipment | Match the exact connector and confirm the required plug-in, battery or phantom power. | When I already own a recorder or transmitter, I need a mic that works with its input and power supply. About 17% of consumers would prioritise compatibility with equipment they own. |
A directional pickup pattern does not make a microphone compatible with every recorder. Shure specifies a TA4F connection for the CVL and compatible wireless bodypacks, while Audio-Technica’s AT831b uses a different power-module arrangement.
Identify your device’s microphone input and power capability before choosing the microphone termination or a manufacturer-supported connection method.
A compatible bodypack or audio interface may be needed as well as the lavalier.
RØDE specifies omnidirectional capsules for the smartLav+ and Lavalier GO; Shure describes the cardioid CVL as rejecting unwanted sound. A convenient connection alone does not establish that a mic suits a noisy room.
If nearby sound is the main problem, compare cardioid models that work with your equipment. Consider an omnidirectional model when its connection and placement flexibility better match your priorities.
Fabric contact can be audible during speech, even when the microphone is otherwise suitable.
RØDE advises clipping a lavalier on the chest about 20–30 cm from the mouth. Keep fabric clear of the capsule and record a short movement test before reading the bulletin.
Audio-Technica specifies battery or phantom-power operation for the AT831b power-module configuration; wired AT831 operation has its own phantom-power requirement.
Check the requirements of the exact version you are buying, the power available from your recorder or interface, and whether the required module is included.
Shure’s CVL and UL4 are relevant when assessing directional lavaliers for spoken bulletins.
The AT831 family offers a cardioid lavalier route for buyers considering a wired recording chain.
RØDE’s smartLav+ and Lavalier GO suit different connection routes: a compatible smartphone TRRS input or a compatible 3.5 mm TRS microphone input, respectively.
No. Shure describes its cardioid lavaliers as rejecting unwanted sound, but a directional microphone cannot remove every sound reaching its pickup area. Reduce noise you can control and test a short recording in the position where you will read the bulletin.
RØDE recommends placing it on the chest about 20–30 cm from the mouth. Keep the capsule clear of rubbing clothing and make a short test recording while moving as you normally would.
No. RØDE specifies the smartLav+ with a TRRS connector for compatible smartphone inputs, whereas Lavalier GO uses TRS for compatible Wireless GO-series transmitters and other suitable microphone inputs. Check your phone or adapter’s microphone-input requirements before buying.
A wired lavalier alone does not use a radio transmitter. If your setup includes a wireless transmitter and receiver, check the exact equipment, frequency and planned use against current Ofcom requirements before operating it in the UK.
