Why are some things listed twice? Isn't that like giving some options an unfair advantage (like the sm7b which is now a shoo-in because it's both 1st and 2nd place)
The Razer Seiren mics are actually suspiciously similar to the Yetis.
The specs on paper are essentially identical, the feature sets match up, even form factor and physical arrangement. Hell, Razer's shock mount looks like they took a Blue Radius off the shelf and painted it black.
The Seirens aren't as good as the Yetis for various reasons -Build quality isn't up to snuff, they're worse with background noise, their price is usually higher, etc. But they just aren't THAT bad.
