Edit: HiBy FC3 also supports mic, also based on 9281 chip, measured
here.
Yes, HiBy FC1, 3 and 4 also support mic-in, I didn't mention them because they don't have that exact "just a female jack connector tied to a USB plug" form-factor.
The FC3 might be my highest-fi DAC yet, even compared to my desktop units, but I will say it keeps reminding me of some of its bad reviews about mysterious sudden-death cases with some of its behaviors sometimes, e.g.:
- I like to see it stop operating (light goes red) after stopping the music, before I unplug it, kinda like a USB drive, to prevent damage (heard ugly noise when I unplugged it with light not-red), and it sometimes just doesn't, and I'm not even using it in any fancy USB-exclusive/bit-perfect mode, it should be released normally when the music stops, but sometimes it just stays active
- Had the opposite problem for the first time just last week: plugged it into my estat energizer, which sends it straight to high-gain mode because high impedance, and it wouldn't turn on. No inactivity symbolized by red light, nothing, no light, no sound. Only got it working by first plugging it into the phone without load, seeing it flash for a bit looking for a load (turns off if it doesn't find one, that's normal) and
then plugging the energizer. Worked fine for the rest of the session, but it's got me wondering and worrying now.
