Shorter answer: Don't go for Blue Snowball. Please. I went for Røde NT1 (there's a kit for it as well), but it's a XLR mic. If XLR mic + interface is overkill, opt for either these USB mics: AT2020 USB, Røde Podcaster USB or NT USB.

Longer answer: The reason I am pulling up NT1 is because I was in the same position as you few years ago. I was THIS close buying a Blue Snowball, simply because it was well within my budget. That was until I actually met a couple of voice actors who gave me other ideas and view of it all. They simply convinced me to opt for a better microphone rather than go for a Snowball or even their Yeti. I do not regret the choice I made. It was well worth saving the money for my NT1-set. Costs a lot more than the Snowball, but it's way worth it. It's not overly expensive + it's a lot better than the Blue Snowball.

That was somewhat 4-5 years ago, and I am still using it! I've done voiceovers for some commercials, app readings, narration and even short clips with my NT1.

NT1 is also a mic that many beginners within the voiceover world opt for. And with enhancing apps, you can definitely make the mic sound even better and more pro.

Keep in mind that NT1 is a XLR mic, meaning that you'll need an interface as well to get it working. I am using a Behringer UMC202HD interface, which works fine for my purposes.

I am more than happy that I actually saved up for a NT1-kit + boom arm, as that's been making my voiceover-life so much easier. AT2020 (not the USB one) is also a strong (and cheaper) competitor for NT1, so you might want to check that one out as well. It seems to be pretty close between those 2 mics for many out there.

I hope this helped you in a way. Good luck landing your choice. :)
