Choose the microphone connection to match the device you already own: a compatible phone may need a TRRS connection or CTIA-compliant adapter, while a recorder or camera needs a suitable external microphone input; a locking TRS microphone is for a matching input or wireless system. For an oral-history interview, plan stable clothing placement and check whether you need a separate microphone for each speaker.
If you record straight to a phone or tablet, start with its microphone input and any required adapter. Shure specifies a TRRS connection or an appropriate CTIA-compliant adapter for its MVL; that does not make it compatible with every phone.
If you already use a recorder, camera or computer, check its external microphone input before choosing a clip-on microphone. Sony lists compatible external-mic inputs as a use for its ECM-LV1, while power requirements still depend on the connected equipment.
If the interviewer’s questions matter to the finished recording, plan how both voices will be captured. University of Leicester oral-history guidance suggests considering two microphones when the interviewer might otherwise sound too quiet.
Check the recording device’s input first, then decide whose voices need to be clear and where the microphones can sit without rubbing against clothing.
| Concern | What to check | Who this matters to |
|---|---|---|
| Clear speech in the room | Check the clip and windscreen, then make a short test recording in the interview room with the cable secured. | I need the narrator’s words to remain understandable despite room sound and movement. Around 29% of consumers put clear speech in the interview setting first. |
| Device connection | Match the microphone plug and power requirements to the device’s microphone input; confirm that any adapter carries a microphone signal. | If I am using a phone, recorder or camera I already own, the microphone has to connect to it. For around 29% of consumers, compatibility is the primary concern. |
| Both speakers | Decide whether both voices need comparable clarity and, if so, check the number of usable microphone inputs or recording channels. | When the questions need to remain in the archive, I cannot rely solely on a microphone worn by the narrator. Capturing both speakers comes first for around 18% of consumers. |
| Stable, unobtrusive placement | Look for a secure clothing attachment and a cable you can keep clear of fabric and hands. | I want the microphone to stay in place through a long conversation without drawing attention or picking up clothing movement. Around 24% of consumers prioritise placement and handling. |
A phone-oriented TRRS plug, a recorder microphone connection and a locking TRS plug are not interchangeable simply because they are described as 3.5 mm.
Check the recording device’s manual for its microphone input, wiring and power requirements before ordering.
A mismatch may mean using a compatible adapter or choosing a different microphone.
Fabric contact and cable handling can be audible throughout an interview; placing the capsule too far away can also leave speech quiet.
Secure it near the lapel or breast-pocket area, keep fabric clear of the capsule and make a short test recording.
Moving a microphone closer to the speaker does not eliminate traffic, household activity or an echoing room.
Choose the quietest practical space and listen to a test recording there before starting the interview.
A microphone worn by one person does not ensure that the other person will be recorded at a useful level.
If both voices need to be preserved, check whether your recording setup can accept and capture a microphone for each speaker.
Two microphones can also mean more cables and more recording files to manage.
Shure’s MVL represents a wired, phone-oriented route for close-miked speech.
Sony’s ECM-LV1 represents a wired option for devices with a compatible external microphone input.
RØDE’s Lavalier II is a low-profile wired microphone with a locking connector for compatible equipment.
This wireless microphone set is worth considering if you plan to mic two interview participants; confirm its device connection, clothing attachment and recording arrangement before choosing it for oral history.

Consider this set when both interview participants may need a microphone, provided it works with your recording device.
The listed bundle has 2 TX and 1 RX. Check how each transmitter attaches to clothing and whether your setup captures both speakers as needed.
Attach it to stable clothing near the interviewee’s mouth, clear of rubbing fabric. The International Association of Sound and Audiovisual Archives advises a position about six inches (15 cm) from the mouth; listen to a short recording before the interview begins.
One lavalier may pick up both voices, but do not depend on it for balanced speech when the interviewer’s questions must remain clear. University of Leicester oral-history guidance suggests considering two microphones if the interviewer may sound too quiet; check that your recording setup can handle them.
No: the connector and any adapter must carry a compatible microphone signal. Shure says its MVL works with most Android and iOS devices that have a TRRS 3.5 mm jack or an appropriate CTIA-compliant adapter, so check your own device before buying.
If an organisation handles identifiable interview recordings, it should check which UK GDPR lawful basis applies and plan how recordings will be accessed, retained and published. The Information Commissioner’s Office provides guidance on consent, but consent should not be assumed to be the required basis for every project.
