A cheap XLR adapter to use 3.5mm microphones with phantom power. Is it worth ?

 

Hello everyone, I'm a beginner. I've made a pair of microphones using the Primo EM273 for my Sony A6600 camera. Recently, I bought a Zoom H6 recorder, so I need an adapter to connect the microphones. I've searched many options (such as the BOYA 35C-XLR Pro, RODE VXLR+, R?DE VXLR Pro, etc.), but they are too expensive. After searching for a long time, I found this one, priced at only $7.5. It's made in Guangdong. The seller said it has a balanced output.I opened it up and took some photos, but I don't really understand circuits. Although it looks a bit strange in shape.Could you please help me determine if it's worth it? Thank you.

I don't know this brand but I've tested some cheap XLR to Plugin adapters. The 3,5mm Jack is not very reliable and these are sometimes wrongly connected. I had one that shorted the PiP when using a mic with a mono 3,5mm Jack. I've some other NoName ones that have less noise than the Rode VLXR+. I replaced the crappy 3,5mm with a short cable and wire plug.?

Has the new H6 no 3,5mm PiP built in or on the extension Module?

Zoom h6e, It has no built-in 3.5mm pip, So l have to use a adapter
 

Do you have a link for the adaptor you're trying? I can't see much detail in your photos. Also, please post some pix of your mics.

That board looks like it has 3 transistors on it, so it might be similar to the "Schoeps" circuit that's been used in the Alice mics detailed in this forum. Anyway, just try it.
 

? ?Here is the link.The seller also sells BUB adapters.The images in the attachment are high resolution.

I tried this adapter, and there's a toggle switch on the circuit board. By default, it's set to -10dB, and it's very quiet at this setting, but the waveform inside the recorder is not very prominent. When I switch it to 0dB, the background noise becomes significant. I'm concerned that this adapter might not be optimal for my EM273 microphone's performance.

Below is the connection diagram for my EM273.I connected a 100-ohm resistor between SOURE and GND (micbooster said this is equivalent to using an EM272).By the way, if I need to drive this with Simple P48, what size capacitor and resistor do I need? Thank you.
 

I haven't seen that design before, but I put schematics and test info from various similar adapters here:
