Razer Seiren X review – Sleek, attractive microphone for on-the-go streaming

Razer is making a big play to entice streamers, as we’ve seen with their Razer Kiyo, which is the first webcam to have a built-in ring light for shadow removal and lighting. It’s a good camera, that’s capable of outputting 720p at 60fps, which is more than good enough for the little window embedded in streams. One of its best features is that it’s a small, unobtrusive plug-and-play device, making it ideal for those who want to take their streams on the road.

That’s the same ethos behind the Razer Seiren X, a diminutive take on the Seiren, the company’s older “studio grade” microphone. The Seiren X is small, unobtrusive, and purpose built. It’s meant for streamers who don’t want or need great big microphones taking up desk real estate, or want to be able to pack the thing into a bag and stream on the go – from a hotel room, or a conference, or whatever it is young influential people on the internet do these days.

Unlike its bigger brother, the Seiren X, there’s no fancy 24-bit DAC or optional pick-up patterns. You can’t set the mic to record in bi-directional, omnidirectional or stereo modes. Instead, it employs a cardioid pickup pattern, which is perfect for speech and vocals, as it rejects sound that isn’t from directly in front of it. It also has an internal, built-in shock mount, to cut down on mechanically transmitted noise.

Taking it out of the box, it’s about the size of a can of Red Bull. The build quality seems to be entirely ok, until you screw in the base, which adds a necessary bit of heft. There’s honestly not very much else to the device. It comes with a standard (thankfully removable) micro USB cable, and that’s really it. There’s a 3.5mm headphone jack on the underside that’s used for latency-free monitoring, but it’s a little on the soft side, and you’ll have to fiddle with software and hardware volumes to find the right balance. It can also be a little fiddly to plug the 3.5mm and USB cables in. On the device itself, there’s a single dial for volume, and a button that mutes the mic.

As with the Kiyo, the Seiren X doesn’t interface with Razer Synapse, so any of the real fiddling and tweaking you do will have to be done within your streaming software of choice; usually XSplit or Open Broadcaster Software.

As for how it sounds? I like it a lot. Yes, it’s prone to picking up It’s entirely adequate for its purpose and position as an on-the-go microphone. While there are better microphones available, they’re a little harder to get locally, making the Razer Seiren a decent choice.

It’s a sleek, attractive and importantly portable microphone that doesn’t take up much desk space. It can be attached to a boom stand (though you may need an adapter). It is, otherwise, unremarkeable, though a decent option in its price range, especially locally. If you’d prefer something a little more robust than a Samson Go USD condenser mic, and don’t want to import the better Blue Yeti, then the Razer Serien X is a good choice. Locally, it’s available for prices that suitably match its $100 US price, unlike the Kiyo which seems have a premium on it.

If you’d prefer something a little more robust than a Samson Go USD condenser mic, and don’t want to import the better Blue Yeti, then the Razer Serien X is a good choice. It’s big enough to record your voice well, but small enough to throw in a travel bag.
