I've come up with what is hopefully a better solution. Use the app here. Install the app on both devices. There are many similar apps to this so if this one doesn't work perhaps try another one. The app listed works over Bluetooth rather than WiFi. I hope this is OK and it should avoid latency. I'm not sure why I didn't make the link in my head that what you needed was a voice communication app. The old solution is below:

There certainly seems to be a gap in the market here because I can't see why this would be impossible (actually, thinking about it, capturing all device audio might be an issue [although you would only need to capture audio input which wouldn't be...]). I have a solution but it's a rather hacky one and will require root, I'm afraid.

NOTE: I haven't used any of these apps myself. Be careful when installing unknown applications.

Host a WiFi hotspot on one device and join the hotspot on the other. Make sure to turn off data before doing this. This way, the devices won't have an Internet connection but they will have a network connection.

Install AirAudio on the device that you wish to stream from.

Install Microphone on the device that you wish to stream from (this app may have some latency but hopefully not).

Install UPnPlay on the device that you wish to stream to.

Turn on the Microphone application so it starts recording everything and then set AirAudio to stream all device audio over DLNA and then use UPnPlay on the other device to recieve this stream.

I don't think this will work well in practice but it may be worth a try.

Hope this solves your issue.

[question] What are some good mic recommendations for an android phone? Are there any mics that don't need an adapter?
When looking for a microphone that works well with an Android phone and doesn't require an adapter, it's important to choose one that can connect directly via USB-C (if that’s the type of port your phone has) or has a 3.5mm jack that is compatible with mobile devices. Here are some good microphone options that are designed to work seamlessly with Android devices: Shure MV88+ Video Kit: This is a high-quality, versatile microphone that comes with multiple accessories, including a digital stereo condenser microphone that connects directly to Android devices via USB-C. It's ideal for capturing high-quality audio for video, interviews, and even ASMR recordings. Rode VideoMic Me-C: Specifically designed for devices with USB-C ports, this microphone is compact and convenient for on-the-go recording. It attaches directly to your phone and includes a furry windshield for outdoor recordings. Sennheiser Memory Mic: This is a wireless option that connects to your phone via Bluetooth. Although it's a bit pricier, it offers excellent sound quality and the convenience of recording without a physical connection to your phone. Boya BY-M1: This is a budget-friendly lavalier microphone that works well with smartphones and includes a 3.5mm TRRS connector, ideal for vlogging and podcasting. It comes with a lengthy cable, allowing you to record audio from a distance. Zoom Am7: This is another excellent option for Android devices with a USB-C connection. It's a midrange stereo microphone great for recording music, interviews, and ambient sounds. Each of these microphones offers a different mix of features and pricing, so consider what fits best with your recording needs and budget. Whether you're recording podcasts, videos, or ambient sounds, there's likely a microphone in this list that can meet your requirements without needing an additional adapter. More on reddit.com

Wireless Lav/Microphone System for Android - Rode Wireless Pro?
I'm a bit confused by the question. I want it to be compatible with external lavalier microphone for visual purposes. By this I understand you would like a lavalier mic, a small mic that clips to clothes or gets hidden under them. If I do not plan on using the built in microphone, do I need to get the Pro? By this do you mean you don't want to use the mic built into the transmitter? or do you mean the included lav? If you mean that you don't want to use the mic on the transmitter then you should go with the Pro. The Pro for 300 comes with TX x2 RX Charging case Accesory case Lav mic x2 etc The Go III for 200 TX x2 RX Pouch etc The lavs are 100 each and the charging case is like 60 so the Pro is like 160 dolars in savings kindof. The lavs are really good and you'd have to spend a loooot more money to get lavs that are better in quality. If you mean that you don't wanna use the included lavs with the Pro I'd say you can go for the Go III if you already have lavs you want though I'd honestly still go for the Pro for the charging case alone. If you don't have lavs you wanna use then I'd say unless you plan on spending a lot of money on broadcast quality lavs, stick with the Pro. More on reddit.com
