I'm most curious about those onboard mics, personally. 19.4 mm is just shy of what is traditionally called "large" in the diaphragm sizing world. Medium diaphragm? They look stout.
I've stealthed quite a few shows with my H1essential since getting it in February 2024. While the XY90 stereo 'image' is not the most natural and open, it's undeniably reliable and forgiving, both of which are perfect for flying under the radar. Problem is, the built-in mics of this device are not impressive in the slightest. They're plastic, as is the rest of the device. It's small, handy, cheap and does an "ok" job at what I'm using it for. Any tape is better than none, I've always held that belief near and dear.
One of my all time favorite bands, Supergrass, has reunited to perform their debut LP, "I Should Coco" in it's entirety live in concert for it's 30-year anniversary and I am stoked beyond what words can convey. I'm very strongly considering getting this device to record the show. Since I doubt the 'Grass and the venue would be cool with me setting up a full rig (maybe worth asking?), I'd like to at least walk out of there with the best recording I can manage, and this device may just be it.
