Can a bluetooth headset be used as a lavalier microphone?

Question

Bluetooth

You need to record a video from the lecture. A phone with a good camera and enough memory and battery is on a tripod.
Can a bluetooth headset be used as a lavalier radio microphone? What parameters of the headset to pay attention to when buying?

UPD: I found in a search that even the best Filmic Pro video recording program, when switching to a bluetooth device, refuses to record at 44 or 48 kHz, and writes only at 16 kHz. The site says it's a system problem.
I continue to search, I don’t believe that no one has guessed to “turn the bluetooth channel upside down” and turn a cheap headset into a high-quality microphone.

Answer 1

I also add to the answer above that BT headsets will not give the same quality as a regular buttonhole.
If the budget allows you to take a recorder, like Zoom H1N + buttonhole - it will be super.
If not, you can look at the option to take a buttonhole that can connect directly to a smartphone, for example Rode SmartLav + (Or an analogue, I know exactly for this one - that's why I give it as an example).
I know guys who write a podcast for such a configuration with a very good sound, and from the equipment there are two iPhones and two Rode loops. And of course post-processing, but that's a completely different story ...

Answer 2

It is possible but not necessary, since the quality of the microphones built into such headsets ... to put it mildly, is such a rule. It's better to take a normal buttonhole and an external recorder.

Answer 3

I heard that headsets are not suitable as a radio loop. But I don't understand why. Maybe some will fit.

Because not all phones can write video with sound, the source of which is Bluetooth !!!

Rode SmartLav+

Gorgeous!

whether he will be able to cut out unnecessary pieces from the video and overlay titles.

Goodbye!

Look, on android it’s generally a problem to use an external microphone for recording, even a buttonhole, even a bluetooth, so don’t rush to buy microphones.
Previously, I used this application https://play.google.com/store/apps/details?id=com.... and there is such an option, but on Android 9 and Huawei phone, these options stopped working.
Try the light version, if this option works, you can try it on a bluetooth headset.

Well, do none of your friends have a headset to try it yourself?

What is the distance? if not too far then the microphone is a gun, something like a Rode VideoMicro. They are highly directional and write the sound where it is directed.
If far away, then look towards the wireless buttonholes.
If you use a microphone, then you need to take care of the adapter so that the microphone in the phone is defined as a headset (sometimes such adapters come with the lavaliers).
