Razer Seiren V2 Pro Review

Razerthink – The latest microphone from Razer is the Razer Seiren V2 Pro. Razer Seiren V2 Pro is a dynamic USB microphone that offers professional-grade quality for the broadcasting needs of streamers. The Seiren V2 Pro, on the other hand, replaces the Seiren Elite in the professional class. Technically, it is a 30 mm dynamic microphone with a high pass filter whose job is to eliminate annoying noises at low frequencies, such as the hum of a computer fan. Users of this microphone will sound like they are in a soundproof studio, if Razer says.

Razer is no stranger to microphone making, and the new Seiren V2 line has two options for about the same price. The Seiren V2 Pro, which replaces the Seiren Elite, carries an MSRP of $149 and has many pro features that the $99 Seiren V2 X doesn’t have but is still affordable. Enough to support Razer’s motto, “for gamers by gamers.”

For specifications, the Razer Seiren V2 Pro is a 30mm Dynamic microphone with a Cardioid sound pattern. Because this microphone is Dynamic, not a Condenser model, of course, it also doesn’t require additional power from Phantom Power. Although the sensitivity of the capture is not as that of a Condenser microphone, this gives it its advantages. Users do not need to set the recording environment silent as if using a condenser microphone.

In addition, just as this microphone is intended for streamers, the Cardioid pattern is indeed more intended for vocal sound capture, namely sound sources that are “close” and “dry.” Not only that, but this microphone also has excellent features, namely High Pass Filter and Analog Gain Limiter. The High Pass Filter feature is similar to Active Noise Cancellation, but here the quality is specifically able to filter out low-frequency sounds and only pass high-frequency sounds.



By activating this feature, low-frequency noise around the user will be silenced. Examples include the hum from the PC, fan, air conditioner, and so on. By activating this feature, the user’s vocal voice will also feel more prominent so that every pronunciation will sound more transparent and more precise. As for the Analog Gain Limiter, this feature can normalize the volume of the given sound input so it’s not too loud, which usually feels annoying when listening to it.

The Razer Seiren V2 Pro design may not be much different from most broadcasting mics. It has a capsule or cylindrical shape, with mountings suitable for placement on a desk. The Razer Seiren V2 Pro features the same capsule design first introduced with the Seiren Mini, which is a welcome change from the cylindrical design of the first Seiren microphone. The microphone feels like a uniform minimalist dream: the same color and pill-shaped design, reimagined with additional features for each new SKU. The occasional anomaly, like the pink stripe, including the first-generation Seiren X, but the V2’s mics all look very similar.

The microphone has a thread at the bottom of the Y-shaped mount that screws into the included mount or boom arm. The stand offers a firm grip, so you can point the microphone to whichever position works best for you, and you can also tighten or loosen it further if you wish. You can potentially remove the mount from the microphone altogether, but since it has a thread at the bottom, there’s no point in doing so unless your boom arm has its tool.




The microphone body has a matte black appearance, with a metal body that is quite sturdy. At the bottom, there is a thread for mounting to a standard type of microphone stand to use various types of microphone stands as needed. The V2 Pro is equipped with a windshield filter, which helps eliminate sharp noises or wind noise. It’s not a pop filter, and it doesn’t work that way, but it should soften the plosive a bit.

In addition, there is also a USB Type C port, which is, of course, useful for connecting a microphone to a PC. This microphone is secured using a USB Type-A to Type C cable, with a length of approximately 1.5 m. There are indicator lights, mute buttons, volume, and gain knobs on the front. Razer Seiren V2 Pro is quite helpful for users to adjust the volume while doing live streaming. With this physical knob setting, users can easily access the microphone volume.



The indicator light is pinned together with the mute button, where the light will be red when the microphone is muted and green when it is unmuted. A mounting desk also accompanies this device in the form of a round iron plate as the foot of the microphone. In addition, there is also a foam microphone head cover, which also functions as a pop-filter microphone for users.


Razer Synapse is where to get the most out of the Razer Seiren V2 Pro microphone, so it’s essential to have it installed if you want to get the most out of your microphone. On the one hand, you can monitor and adjust the headphone volume, increase the microphone level, and activate the High Pass Filter and Analog Gain Limiter. The Stream Mixer tab of the Synapse software is where the microphone fully reveals its true self, but it will take some mental gymnastics to understand what it can do. The help link provided by Razer on the software leads to a 404 page, so you’re pretty much alone here.

“Razer is constantly improving the software to make it easier to use; they are also working on educational content that will help beginners to understand better all the various features of our hardware and software, to get the most out of their professional setup,” said Ole Grosstück, Business Manager, MENA, Razer.)




When you plug a microphone into your PC, it immediately adds ten audio and three microphone inputs. The audio inputs are Headphones, Aux 1, Aux 2, System, Music, Game, Voice Chat, Browser, and Sound Effects, while the mic inputs are called Microphone, Stream Mix, and Playback Mix. Each of these inputs can be assigned to a different application using the sound mixer built into Windows, and the volume can be adjusted from the Synapse software. Each information has two volume sliders, one that goes into Stream and your headphones. They can be linked together or arranged individually.

Suppose you want to add a game in Stream Mixer. In that case, you must first add a ‘Game’ input from Synapse by clicking on ‘Add New Input’ and selecting ‘Game.’ Then launch Windows Sound Mixer, find the game from the list (which should be running in the background), and manually set the output and input devices to your chosen port. Then, in the Synapse software, you can control the two-volume sliders. Once you’ve done that, you’ll need to add the ‘Game’ input in OBS (or whatever software you’re using for streaming) and customize it there.

You’ll need to repeat the same process for any other apps you want to add, such as a music player, web browser, or Discord for voice chat purposes. Fortunately, once you set the port, it will not be reset, but the Synapse software is required to run in the background for all ports to be enabled correctly. It’s a complicated multi-step process, of course. Still, the granular control it brings to every aspect of audio will be welcomed by pro streamers, especially since they don’t have to invest in an expensive mixer to replicate some of these features.

If you’re a novice user who wants to plug in a microphone and go live, the V2 Pro can be a bit overwhelming. The most terrible problem is that the mic adds almost 13 additional ports on your PC with no easy way to disable it from the Synapse software. After a while, scrolling through a long list to switch between different audio sources can be pretty annoying.




In terms of actual performance, the Seiren V2 Pro is quite outstanding. The sound quality is rich and full sounding. Of course, it will pick up every little sound around you because it is a cardioid microphone. There is no noise filter in the Synapse software, so you will have to apply it to any other software you may use manually. This microphone has physical volume and gains knobs and virtual ones in its Razer Synapse software, plus it can function at three different sampling rates: 44, 48, and 96 kilohertz. The higher the hertz, the higher the quality.




At 96 Hz, the sound produced by the microphone is as close to the original sound as possible. Using these high frequencies and control gain allows for a unique experience. The frequency I use depends on how I want it to sound. Ninety-six kilohertz will sound cleaner than 48kHz but takes up more file space. 48 kHz is fine for recording and doesn’t require much adjustment to the EQ — 96 kHz takes a little more patience to get them sound right.


The Razer Seiren V2 Pro is now available on the Razer website for US$149.99


The Razer Seiren V2 Pro is a feature-rich, quality microphone perfect for pro streamers. Its built-in Stream Mixer offers granular control over the audio aspect that will satisfy anyone looking to produce a polished chunk of online content. I like controlling the audio channel and changing the EQ, which defines who this mic is for. Professional streamers are the core audience for this product, and if you are a novice user and you want the microphone to work right away, you are better off looking for other options; these are far from easy-to-use microphones,
