We all need microphones these days. I have 3, but one of them is so versatile that it’s pretty much the only one I use.
That’s the Zoom H1 Handy Mic.

The Zoom H1n goes everywhere and, if you remove the batteries when it’s not in use, then it is not a battery hog. (But if you leave them in when powered off, your fresh batteries may be dead when you come back.)
I’ve used this for all sorts of things. You can hear online that I’ve used it to record chapters or mobile podcasts, but I’ve also taken it to interview elderly people I know to capture their stories.
This mic is great at capturing close-up sound, but you can also put it in the middle of a room, just let people talk, and find that it picks up most voices equally.
I use the Zoom H1 more than any other mic because it goes more places and sounds better while its there. The Blue Yeti I have has literally only been used once because it was a step down in every way.
Even better, my mic is so old you can’t get it anymore (only its upgrade) AND IT STILL WORKS GREAT. And in a world where everything electronic is pretty much built to die within 2 years, I consider that a huge win. I’m on year 5 with mine, and it’s still working great!
So, if you’re in the market for a mobile microphone that captures great audio, give the Zoom H1n a chance.
It hasn’t disappointed me yet.
Oh, and grab some foam toppers while you’re add it. They’re an inexpensive add-on that will help you create expensive-sounding results.
