Question about Insta360 One R Twin Edition

Unfortunately, I don't have any experience with the 360 module in such a situation, if your question is specifically aimed at it. In any case, I have used it even less than the "standard" module, which is also used sparingly. But I have also made recordings of theatre performances with it. Picture quality is very relative. Considering that I can't compare it with other action cams, and that we're talking about a tiny thing with just such a sensor and lens (which is also very wide), I found it quite remarkable. However, these were rather quiet pieces, with static light, and I didn't need any special fast shutter speeds, or anything else...I could probably, except for increased ISO, use pretty much what the cam offers in terms of quality. But it's not like I'm saying I wouldn't rather set up another camera if the situation allows, and the image is robust.

Apart from the image quality, which may be sufficient depending on your requirements, there are still a few snags...

The micro adapter was not really an issue for me, as I recorded the sound completely externally, but I don't think I've only heard good things about it. The mic from the camera itself is just barely good enough to synchronise the external sound with. Maybe you can solve it with a small recorder...don't know what kind of music you're talking about, but the Zoom H2n, for example, is very compact and records with a pretty decent quality.

But what I see standing in the way of "just stick it anywhere and run it" the most: I don't know about low resolutions, if that's an option for you, but at least with the higher resolutions I've encountered the problem in tests that the camera automatically switched off after so and so long. Probably overheating protection.

In the end, the solution was a USB powerbank (so no ext. mic anyway), and that I replaced the battery module in the frame with a matchbox (because somehow only without the battery the power doesn't run through the battery (which is probably part of the heat problem)...and because the other two modules in the frame don't hold when you take out the battery module, and I had nothing better to hand as a "placeholder"). If you don't necessarily want to film whole concerts at a stretch, maybe it's not an issue, but it's not without problems.

If I remember correctly, I still had to stop and restart the recording once during the piece, so there's probably another limiting factor that I don't remember exactly (maybe file size or something), but the camera didn't switch off any more, and the control via phone also worked amazingly well (though it was also very close...was still afraid that the connection would break, but it was always there again).

I don't think so. As far as I know, only Apple airpods work with the cam. The 360 sensor is also not specifically designed for dark environments. The 1inch sensor might (but not part of the Twin Edition).
