    I have noticed one problem with the external microphone.
    The sound is not of a similar quality when first camera is switched on and then plugged in external microphone or if a first microphone is inserted into the camera and then camera is switched on.
    The sound is much better when you first plug external microphone in camera and then turn on camera.

    I made several USB connectors. I bought Edutige mic ETM 001, 2x fake Sony, A and B original SJ, 3x some cheap mic from China.
    Sound is OK in the house, but when I put a camera on a motor bike is not good.
    I do not know why but not good

    For the first problem: I also tried with SJ7 & SJ micB, but sound quality is the same.
    For the second: Mic line may catch bike noise.
    You made external mic connectors?

    I'm only guessing but... are you sure the external mic is working at all in either case? I wonder if the camera doesn't recognize an external mic in one of those two instances: 1) connected-power up; 2) not connected, power up, connect. That's only a guess, but I'd check to be sure which mic is working when.

    Oh, and a third possibility: the internal and external mics are both on in one of those cases.

    Micing a motorcycle is a hard job. Wind noise, whining gears, slapping chains, they all add to the noise that covers the exhaust sounds most people want.

    Yes, I made a few external connectors for a ex mic according to the previously illustrated scheme.

    Everything is possible, I do not know how to check it out but I think external microphones work in both cases but I do not know how the tone is different when the camera is on/of.

    Sorry about my English. I use translator.
    Thanks

    The translator is not a problem for me. :)

    The best way to test which microphone is working is to play some music on, for example, a smartphone. Put it next to the camera and then the external microphone. If the music isn't very loud, only one microphone (if both of them are working) will hear the sound.

    Your result is very interesting.
    I also made external mic adapter, so tried connecting before and after power on.
    But sound quality is same.
    How about your SJCAM original mic? With it also change?

    I don't have an external mic right now, so I can't give any comparison. I was only suggesting a way to test mics.

    Thanks everyone.
    The camera otherwise works great.
    So first I turn camera on and adjust the volume of tons. Camera turn off. Then first turn on the mic in camera and turn camera on and then the sound is okay.
    It's the same with the original mic.
    I'll try what RBEmerson wrote.
    I noticed that when I put the firmware V1.4.6. Maybe I'm doing something wrong

    The translator (what's your home language? If it helps, I also know German) seems to have a problem with this. I want to be sure I understand what the translation says.
    You turn on the camera. You adjust the volume and the camera turns itself off. Is that correct? Plug in the external mic, turn on the camera, and the camera works as it should? Use only the internal mic and the camera works, too?

    OK - if setting the volume causes the camera to shut off, my guess is the firmware in the camera isn't working correctly.

    Please understand I have no connection with SJCam. I'm just a user. I have a technical background (computers and digital systems).

    The firmware version you list: V1.4.6 is, as far as I know, a very old version. The current version is V1.15. Try that version and tell us how well the camera works.

    I do not know, but for SJ6 Legend I see it now in official support sjcam HD.com that is a new firmware Ver. 1.4.7.
    I'll put that new one and try it
    thanks a lot for help

    Different cameras, different version numbers. I just checked the support page. The current SJ7 firmware version is 1.15.

    As I've posted elsewhere (oops - cross-posting - not a good thing), my SJ7 socket only has five contacts.

    Thanks for the videos and the photo but...
    Unless I'm very confused, the USB port on my SJ7 has only five contacts. They're on the top of the small plastic piece in the middle of the socket. There's nothing on the bottom of that piece.

    I've looked at the SJ7's connector with a magnifying lens. There are five tiny strips on top of the piece but nothing underneath.

    It's possible that my SJ7 has an old-style 5 pin connector which, later on, was changed to 10 pin connectors.

    The serial number is 201705011895. I bought the camera in June 2017. I assume the SN says the camera was built in May 2017.

    I've an earlier camera (201701000xxx) - although I can;t see all the pins on the USB socket it works with the external mic which (according to previous layouts) uses some of the extra 5 pins.

    OK - I'll start the process in Nianeko's video and see if I can find anything from the lower pins.

    @TonySosa - do you know whether there are any five pin USB connectors in the SJ7 production run(s)?

    Hi
    I'm going to make one for myself to use with SJ6. Can we use any external mic with 3.5mm jack? I want to buy mic as well for motovlog I don't know which one would be the best.
