What matters when choosing a lavalier?
3.5 mm TRS recorder route
Choose when: A camera, recorder or compatible transmitter accepts the lavalier’s specified 3.5 mm TRS connection.
Trade-off: A TRS plug must not be assumed to work in a phone’s TRRS headset input.
Direct-to-phone TRRS route
Choose when: One narrator records straight to a phone or tablet with a compatible TRRS input or confirmed adapter.
Trade-off: That connection does not establish compatibility with a TRS camera input or professional bodypack.
System-specific bodypack route
Choose when: A team already uses a transmitter and can identify the exact lavalier connector it requires.
Trade-off: Connector matching and, for wireless use, band and licensing checks add setup decisions.
Once the recording input is clear, check whether the microphone can stay close to the narrator without breath or clothing noise. The priorities below describe consumers recording museum commentary in untreated rooms.
| Concern | What to check | Who this matters to |
| Clear speech in a reflective room |
Check for secure placement near the mouth and suitable wind or pop protection. Shure recommends 15–25 cm from the mouth for its MVL. |
If room reflections compete with my narration, I want my voice picked up from a stable, close position. Around 40% of consumers would put direct speech clarity first. |
| Device compatibility |
Identify the recorder, phone or transmitter input and confirm the exact connector and any adapter path. |
I need the microphone to connect to the device I already record with, rather than choosing by plug size alone. For around 30% of consumers, compatibility comes first. |
| Discreet, secure mounting |
Check the clip, capsule position and cable routing for the way the narrator will move or appear on camera. |
When I speak while moving or being filmed, I need the mic to stay in place without distracting from the commentary. Secure, unobtrusive mounting would lead the choice for around 20% of consumers. |
| Wireless workflow |
For a wireless system, confirm transmitter compatibility, its operating band and whether the intended UK use requires a licence under Ofcom’s conditions. |
Our presenters need to move without a cable to the recorder, so I must account for the radio setup as well as the lavalier. Around 10% of consumers would prioritise that wireless workflow. |

Frequently asked questions
Will a lavalier remove echo from an untreated museum room?
No. Shure’s microphone-placement guidance explains that a microphone cannot separate reflected speech from direct speech after both reach it. Positioning a lavalier close to the narrator can help capture a greater proportion of direct speech, but it does not change the room’s acoustics.
How close should I place the lavalier to the narrator’s mouth?
For the Shure MVL, Shure recommends 15–25 cm from the mouth and use of its supplied windscreen. Test the actual clip position while the narrator speaks and moves; that distance is guidance for the MVL, not a placement specification for every model.
Can any 3.5 mm lavalier work with a phone, camera or wireless pack?
No. RØDE specifies TRS connections for Lavalier II and Lavalier GO, whereas Shure specifies a TRRS connection for the MVL’s compatible portable-device route. Check the device’s exact microphone input and any required adapter; a professional bodypack may need a different connector.
Does a wireless lavalier need a UK licence?
That depends on the transmitter and its intended use; a wired lavalier does not raise a wireless-spectrum question. Ofcom publishes conditions for licence-exempt bands, and its January 2026 programme-making and special events guidance says a Wireless Telegraphy Act licence must be granted before transmission where that licence is required. Check the system’s band, power and use against the applicable Ofcom conditions before operating it.
Should I make a test recording before the full commentary?
Yes. Record the narrator at their normal speaking volume and intended position, then listen for clothing movement, breath noise, room reflections and an appropriate input level on the recording device. Adjust the mounting or recording setup before starting the full take.
