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

I've been using the DJI Mic 2 for about six months now, and it's been a game-changer for my run-and-gun interviews. The internal recording on each transmitter is a lifesaver – I've had a few moments where the wireless signal dropped (especially in crowded areas), but the backup track saved me. The 250m range is more than enough for most situations, and the battery life is solid (up to 6 hours on the transmitter). The only downside is that the case is a bit bulky, but it's worth it for the protection. If you're on a tight budget, I'd say go for the DJI Mic 2 – it's currently around $189 on Amazon, which is just under your limit.

I second the DJI Mic 2 recommendation. I switched from the Rode Wireless Go II because the Rode's internal storage is only 8GB, and I found it filled up quickly on longer shoots. The DJI Mic 2 has 8GB too, but it supports 32-bit float recording, which is a huge plus for interviews where you might have sudden loud laughs or whispers – you can recover audio that would otherwise be clipped. Also, the DJI Mic 2 has a built-in touchscreen on the receiver, which makes it easier to adjust levels on the fly. For your Sony ZV-E10, just plug the receiver into the 3.5mm TRS input, and you're good to go.

I'm going to play devil's advocate here and suggest the Rode Wireless Go II. While the DJI Mic 2 is great, the Rode has a few advantages: it's smaller and lighter (each transmitter is only 30g vs the DJI's 32g, but the receiver is much more compact), and the clip is better for hiding under clothing. I also find the Rode's Series IV 2.4GHz transmission to be more stable in RF-heavy environments – I've done interviews in convention centers where my DJI (I've tested both) would drop out, but the Rode held on. The Rode also comes with two transmitters, so you can interview two people at once if needed. The downside is that it lacks 32-bit float, but for most interviews, 24-bit is fine. If you can find it on sale, it's often around $199, which is right at your budget.

Honestly, for your budget, you can't go wrong with either. But I'd also throw in the Hollyland Lark Max as a dark horse. It's usually around $199, and it has 32-bit float, 24GB of internal storage (more than both DJI and Rode), and a 650m range (though that's marketing fluff – in real world, you'll get about 200m). The build quality is a bit more rugged, and the transmitters have a nice LED screen for checking levels. I've used it for a few months and it's been rock solid. The only thing I don't like is the receiver is a bit chunky, but it fits on a camera shoe mount fine. If you're open to a third option, check it out.

Thanks everyone for the detailed responses! I ended up going with the DJI Mic 2 because of the 32-bit float recording and the backup track feature – that's exactly what I need for peace of mind. I also liked that it has a touchscreen, which makes it easier to adjust on the fly. I just did a test shoot in a busy park, and the audio was crystal clear even when the subject was about 50 feet away. The backup recording saved me once when I accidentally walked too far, but the main track was fine. I'm really happy with the purchase – thanks for all the input!
