Razer Seiren V3 Pro Review: USB, XLR, and 32-bit float

The Seiren V3 Pro is a great mic for a small audience — if you don't need 32-bit float and XLR connectivity in one mic, and you probably don't, there are plenty of cheaper mics that perform just as well.

Who doesn't have a dual-connectivity podcaster-focused microphone these days? It seems like every company vying for a spot on our list of best gaming mics is trying to woo us with dual-connectivity when the entire point of a USB gaming mic is that it can connect to your PC without an audio interface (unlike XLR). Anyway, it looks like we can add one more to the pile with Razer's Seiren V3 Pro, which launched today.

The Razer Seiren V3 Pro is an end-address cardioid microphone with a sleek-if-boring design, a built-in swing mount, and one of my favorite features on any peripheral — a capacitive-touch tap-to-mute button that works flawlessly. It supports both USB-C and XLR connectivity, and it has a headphone jack for zero-latency monitoring, plus an on-mic gain control wheel. It records audio at 32-bit / 96 kHz resolution, and supports 32-bit float — though, only through its Synapse app on Windows.

It's not the first time we've seen a mic like this, but they usually don't support 32-bit float (even though, to be fair, very few people need 32-bit float support). The Seiren V3 Pro isn't unique, but it's certainly rare. It's also on the pricier side, at $249.99 (available now).

Design and Comfort

The Seiren V3 Pro is a fairly standard cylinder-shaped mic housed in a relatively solid matte black zinc unibody. It comes mounted on its own built-in swing arm, which can be attached to the included desktop stand or to a boom arm via a 5/8-27 threaded mount (it also fits 3/8-16 threaded mounts). It has a removable pop filter, which slides off easily (perhaps too easily) to reveal a black grille surrounding the capsule, which has an integrated shock absorber.

Razer's text logo is subtly printed on the left side of the mic in shiny black; otherwise the design is fairly understated (though there is, of course, a thin, customizable RGB light ring around the center. There's also an oval tap-to-mute button on the front (or top, depending on how you end up mounting it). It's a decent-looking mic, but it doesn't do much to stand out aside from looking like it's trying to emulate the Shure MV7+ (and every other mic that's also trying to emulate said mic). The all-black finish is sleek enough as long as you don't touch it; as soon as you do, you'll find it's very susceptible to fingerprints.
