content: Overpriced is in the eye of the beholder. You gotta use numbers when communicating to the rest of us. Of course, if that number is too small, we won't bother looking.Rode Al-Micro will do the job you want. Two microphone inputs plus a headphone output to usb-c/usb-a/lightning connectors.

content: 80€ for an ADCK ist a litlebit to much I would say. Even the most expensive Chipset would cost way less then!

content: Quote from: Lord of nothing on January 06, 2022, 07:58:17 pmThat argument leads directly to "If it's that easy, then do it yourself".Still you have the right to think it's too much, and you might even be right. But what does the price need to be for you to buy it? And if you can't find something for that price, are you willing to do without?

content: i know i know...When I compare it with other Adapter the cost <10€ maybe <20€ the most expencive for my Phone.So why should a default just with a Stereo Input cost 80€.Many Chipset support Stereo Input.

content: You don't have to restrict yourself to USB-C searches. If you find it in any version of USB, then all you need is an adapter to USB-C.Can't answer questions about your gimbal without any information on your gimbal.

content: This is about as small as it gets:https://www.behringer.com/product.html?modelCode=P0BBPYou'll have to mod it to shorten the cable, but given it's only $25, just make sure it works before you mod it.

Either way, it's much higher than mic level.The OP did not say what kind of mic they're using. If it's a 3.5mm TRS stereo plug on a mic small enough to fit on a gimbal, it's most likely an electret microphone. If it doesn't have an internal battery, it would need mic plug-in power. I don't think the Behringer LINE 2 USB is suitable.https://www.startech.com/en-us/cards-adapters/icusbaudio2dThe instruction manual for this one is useless, with no explanation of its capabilities, but I did see a mention of "Microphone is stereo only." This is only visible on the webpage under Technical Specifications/Special Notes / Requirements and the datasheet.If the OP wants to try this one, they should buy it from a retailer with a liberal return policy.Edit: The StarTech product does not claim driverless USB Audio Class 2.0 operation so it might not work on a smartphone.From looking at the FAQ for the RØDE product, it looks like some of the higher price went towards dual mic jacks with auto-sensing jack detection and configuration. I guess the cheap 10 euro adapters are mono to accept the standard PC99 light-pink microphone pinout.

content: https://www.amazon.co.uk/Plugable-Speaker-Headphone-Microphone-External-Compatible/dp/B00NMXY2MOBy chance, I found a USB audio device with a stereo microphone input.I was wondering why so few offer stereo mic inputs. The one I found has the same pinout as a standard desktop PC. After thinking about it, I think I have an idea why.When making a cheap peripheral, the most important thing is avoiding customer service inquiries and returns. If the pink jack is stereo, there's a risk that a mono mic is not detected properly, resulting in audio on the left only or noise in the recording. A mono mic input is slightly cheaper and should still work with a stereo mic for the left mic only.Also, the green and pink plug PC headsets are less common now. Instead, mobile phone headsets with a 3.5mm TRRS plug and the CTIA pinout are much easier to find. Many of the USB audio devices only have a single TRRS jack.So for the maximum compatibility and the fewest customer returns, a USB audio adapter should have a green jack with TRRS in the CTIA pinout. The pink jack should be a TRS jack with mono mic support with shorting jack connections to the green jack to automatically switch the connections.
