This mike sounds really good and can record 24 bit, 48 kHz WAVs. It includes a recorder app, a minijack input for monitoring headphones (which is great, as my phone, a Samsung Galaxy S22 Ultra, doesn't have one) and a "dead cat"-style wind shield.
My only gripe is that the mike is not instantly useable when I connect it to my phone. Maybe it's a phone/OS issue rather than a mike issue, but it can take a couple of minutes for it get picked up by the operating system.
Other than that, this is a really handy little mike that turns your phone into a very serviceable portable recorder.
(Note that this is a directional, mono mike, so not ideal for ambient or spatial recordings.)
