RØDE - Wireless Micro

The best way to get high quality wireless (or wired) audio into the Ultra system is via the USB-C socket on the pod. Yes, you then have to have the camera in the pod, but if you want the best audio that's what you have to do. Examples that should work are the Rode Wireless Micro or the Hollyland Lark A1, both of which come with a very small receiver which connects to phones, or to suitable cameras. And there are probably about 100 similar systems out there, but those are two which I use (not with the Ultra which I don't have, but with cameras from another company). The advantage of going that route is that the audio link to the camera is much higher grade than bluetooth, and the range is far longer. Also, you can use wired USB mics, and as the Ultra is supposed to support stereo, a stereo mic should work well. Actually you should be able to use wireless mics connected via USB in stereo too - both the models I mentioned give fantastic immersive audio when clipped either side of a baseball cap, to match the fantastic immersive video from the camera!

Rode Wireless Micro kit (which can be connected to an audio recorder 3.5mm input now that they offer a free receiver for that purpose - or to a phone via USB-Co or lightning), or Hollyland Lark A1, for connection to phone or any other device which accepts USB audio input. You clip the tiny mics either side of your baseball cap or similar - even inside it with the slim A1 mics - set to stereo, and you get good results from a rig nobody is likely to notice, with no wires. But - if there's any significant wind, you have to fit the fluffy muffs, which do make it a bit more obvious.

Little while back. I posted this review. Rode wireless micro. I use for guitar playing but im also a guitar player. No headphone in so u gotta use a hub to add an extra port, or use bt headphones to monitor. Its rlly good, but i didnt pay close to retail price either https://www.reddit.com/r/iosmusicproduction/s/ixQNIbYtiz

Rode 2 wireless. I film a lot outside and at a distance from the camera. With a wind muff they are awesome

Get a wireless microphone system with a 3.5mm plug, something like the Rode Wireless ME. Plug it into the mic input on the laptop. It runs on 2.4 MHz, not Bluetooth. Interference could be a factor but at the ranges involved in presentations, I have never had a problem with my Rode wireless mics.

Blue Yeti when I'm seated indoors, for portable / wireless lav /outdoor, Rode Wireless. DJI mic is also an excellent choice

Depends on what type of content you make. I’ll assume vlogs so I honestly suggest the Rode wireless microphones with the receiver and a transmitter than can clip into your shirt.
