Best budget-friendly wireless lav mic for run-and-gun interviews?

Great question! I've used all three on various shoots, and for your exact scenario (run-and-gun, solo, under $300), I'd strongly recommend the DJI Mic 2. The touchscreen is a game-changer for quick adjustments on the fly, and the audio quality is excellent—32-bit float recording is a lifesaver if you accidentally clip. The internal storage (8GB) also gives you a backup recording, so if the wireless signal drops, you still have clean audio. It's also very compact and the magnetic clips are handy for mounting on clothing. The Rode Wireless GO II is solid too, but the lack of a screen means you're relying on the phone app or physical buttons, which is slower in the field. The Lark Max has great mics and internal recording, but the build feels a bit less premium and the UI is a bit clunky. For your Sony A7 IV, you can plug the DJI receiver into the 3.5mm mic input, but I'd recommend getting a USB-C to 3.5mm adapter or using the TRS cable that comes in the box to avoid any preamp noise. Also, don't forget to set your camera's audio input to 'Mic' and adjust levels to around -12dB to avoid clipping. For hiding the lav, I usually use a small piece of medical tape (like Micropore) to secure the mic under the collar, and I route the cable under the shirt. For the transmitter, I'll clip it to the back of the subject's collar or put it in a pocket, but make sure it's not rubbing against clothing—that creates rustle noise. Good luck!

Thanks so much for the detailed breakdown, directormaster69! I decided to go with the DJI Mic 2 based on your advice—the touchscreen and 32-bit float recording really sold me. I just ordered it, and I'll be testing it out this weekend on an interview shoot. I'll make sure to set the camera levels properly and use the medical tape trick for hiding the lav. Appreciate the help!
