GamesRadar+ Verdict
Razer's first hybrid microphone stacks up in terms of audio quality to options from Shure, Rode, and SteelSeries. With a classy look and a generous pickup pattern that makes it easy to use, it's a genuine contender in a stacked market. Its price isn't terrible, and it's got some really impressive features, but reliance on Synapse and a USB connection to get the most out of it does hold it back. Maybe if Razer supported the XLR connection with a current-gen audio interface, it'd feel like more of a complete package.

Why you can trust GamesRadar+
Razer's a little late to the party, but its first attempt at creating a multi-connection microphone is here. The Razer Seiren V3 Pro has capacity for both an XLR and a USB connection, and with a serious, studio, Shure-reminiscent design, it's clear that Team Sneki has not come to play around. This looks and sounds like a contender for the top spots on our best microphones for streaming and gaming list, but does it sound like one?
I, for one, am a little surprised to see some pro-level content creation gear coming from Razer in this day and age. Its Stream Controller X has been all but discontinued since Loupedeck was bought over by Logitech. Its presence in the capture card space is pretty much dead; its USB microphones are tiny, unicorn vomit devices that, although sound great, don't look like they want to be taken seriously. The Seiren V3 Pro has a professional, studio look to it that reinstates this brand as a name in content creation again. That said, I can't help but feel its XLR connection is without a friend because Razer's Razer Streaming Mixer is so out of date it should be in a museum.
But surprisingly, Razer has nailed it with this microphone. Its quality is excellent both in USB and XLR modes; it's easier to use than some of the other more premium XLR options on the shelves, and its price is only $249.99 / £249.99, which is actually on par with some of the other premium mics on the shelves today. Razer tax, where art thou?
Design
The Razer Seiren V3 Pro isn't subtle about the fact that it wants to go after the Shure SM7dB. Along with the BEACN Mic, the Maono PD200W, and Shure's MV6, it's joining the lineup of black, cylindrical microphones that want you to talk into them for your podcast, livestream, or YouTube video. This is an iconic look, and I like the way Razer has put its own spin on it.
Around its rim, there's an RGB ring which is fully customizable using Razer Chroma, and the capsule of the mic is covered by a familiar cylindrical pop filter/wind guard. There's some very subtle Razer branding which can be seen if it catches the light, but blends into the bodywork of the microphone so as not to overplay its hand and spoil the Shure lookalike contest.
What I really like about the design of the Seiren V3 Pro is that the mounting system complements the pickup pattern. A lot of XLR mics (and the Shure SM7dB specifically) require you to be pretty close and direct with them; hence why they opt for this black cylindrical design, and their mounting systems reflect that. The mounting arm here is more versatile in order to cater to a more generous polar pattern. I've attached mine to a boom arm and had it hanging down towards me, almost like it is actually a boom mic.
When in shot of my webcam, it does actually look like it's being held from somewhere out of view, and it gives my entire setup a premium podcast host feel. Its angular stand allows for that inverted type of mounting, but if you so please, you can leave it upright on its stand, or boom-mount it so it's facing up vertically. There's versatility here that I really like, and form complements function because the pickup pattern doesn't care about which direction you use it from.

The internals of the mic have had a lot of thought put into them too. The V3 Pro sports a 30mm Dynamic capsule with the below specs that I've compared directly to the Shure SM7dB for context.

The USB side of the microphone obviously demands a few more design bells and whistles than a standard XLR option. There's a manual gain control dial on the bottom of the mic, as well as a 3.5mm headphone jack for live monitoring through a headset. Note that this is reliant on Synapse, or at least didn't work for me until I had Synapse installed, so it isn't on a mere hardware level. There's also a capacitive mute button.
Features
As with the other hybrid mics we've seen hitting the shelves already, the Seiren V3 Pro harnesses the power of both USB-C and XLR connections. I've plugged them both in with different machines, and they've both worked at the same time. It is missing the wireless connection of the Maono PD200W, but in terms of the dual-connectivity it has it matches up with the Rode PodMic USB, Shure MV7+, and SteelSeries Alias Pro. It is probably worth noting that while a USB to USB-C cable comes in the box, you'll need to supply your own XLR cable.
On the software side, a lot of the V3 Pro's best features are reserved for Synapse pairing, which, if you're anything like me, is a big let-down. The RGB, 3.5mm live monitoring, gain control, and mute button all require USB power, so don't go in expecting those if you're going to hook it up using XLR through one of the best streaming mixers.
Synapse is going to give you lots of access to EQ, bass boosting, exciters, noise gate controls, AI noise cancelling, and other settings of the V3 Pro. There's also support within Synapse for 32-bit float support, which barely any of the competition mics have unless you go wireless with something like the Rode Wireless GO Gen 3. Moreover, Synapse now has a full mixing suite within it if you are using USB connections and can't mix using a separate interface. While this is an impressive update to Synapse that gives the Razer mics some longer legs to run with, it's a real shame that you're reliant on the entire Synapse ecosystem to use these things.
There's a reason that Elgato has its own separate software for audio devices, camera devices, and capturing footage with its capture cards. If you're buying one device from a brand, you shouldn't have to download a very intrusive and performance-heavy application that tacks on everything else it makes. Just let me have the parts I do need, and stop making it so hard to install and uninstall this silly program that's insistent on becoming the main character of my PC.
Performance
The first thing I'll say is that I really, really like the way this mic sounds. It captures some excellent quality that's absolutely up there with the Shure and Rode options out there. It's also consistent across its USB and XLR connections, with minimal sound disparity between the two.
I did the majority of testing in XLR mode through the RodeCaster Duo, and I have to say, it's on par with the kind of quality I expect from the Shure SM7dB, although with a few caveats. It feels like because of that extra adjustable gain and lack of 32-bit float, AI noise cancellation, and noise gate through Synapse, it's a bit more unruly. That could be a good thing for you if you've used the SM7dB and you've not got on well with its fairly low gain levels. But it also means that in XLR mode you're going to struggle to keep ambient room noise out of the mix.
Moreover, the pop filter simply isn't as strong as Shure's. Its foam isn't very dense, so it isn't doing as good a job at blocking out those attacking plosives. In USB mode, this is kept under control a lot better, presumably thanks to Synapse, AI noise cancelling, and 32-bit float. The pop filter doesn't do quite as strong a job as I'd like it to in XLR mode, where I feel like it's really going to be needed more for those professional recording quality uses. Its foam doesn't hug the capsule quite as tightly as Shure's does either, so I'm not convinced by it.
What I do love about the Seiren V3 Pro is its pattern, how generous it is, and how that works alongside its mounting design. I mention it in the audio sample above, but there's a brilliant versatility to this mic so that you can attach it to a boom arm at pretty much any angle, and as long as you're in close proximity, you get excellent, consistent studio-quality recordings. With Shure's SM7dB, you need to be a bit more direct and position yourself more closely in front of it to get the best sound, and even though it has some leeway, Razer has nailed an even more accessible polar pattern.
There's definitely still best value in proximity here, but people buying Razer's mic over something like Shure or Rode are likely going to be a little less studied in their mic etiquette, and it feels like Razer is aware of that and is actively trying to make the V3 Pro more user-friendly.
USB connection is good, as you'll hear from the quality above. Besides the gain being a little more muted and more of the Synapse effects working their magic, I'd say it's all pretty consistent with the XLR sound.
It's not unusual for USB mics to be reliant on software for the best results, but I do think Razer has been a tad too reliant on Synapse to get the best results here. No, you don't need Synapse open and running for these to work, but Synapse, when installed, is pretty much always running in the background, so it's hard to tell when it's really in use and when it isn't.
For the V3 Pro's lack of a noise gate in XLR mode, its USB noise gate is very, very aggressive, even after a firmware update to try and remedy this issue. You can hear in the USB sample audio that some of my words, especially at the beginning of sentences or after a small break in speaking, that my speech is getting cut off by the sheer wroth of the noise gate. That's not ideal, and I personally feel like the way Razer's noise gate cuts off any and all noise when it doesn't detect your voice is a bit too obtuse for a professional sound. It ends up sounding a bit cheap, manufactured, and silly when there's a really obvious cut-off of all the audio. If I was listening to a video, podcast, or stream and that was happening, it'd be so distracting I'd end up listening out for the cut instead of whatever a person was saying.
Hopefully this side of things gets patched and fixed as time goes on, but it's a bit much for my liking.
Should you buy the Razer Seiren V3 Pro?
I think there's real value for money in the Razer Seiren V3 Pro. The kind of quality it gives you in either XLR or USB mode is superb and is definitely good enough to compete with the Shure and Rode options out there. If you're a fan of the design of the Shure SM7dB but don't want to pay that much for it, this is a strong alternative that gives you a more accessible and user-friendly method of using it. Its noise gate in XLR isn't ideal, and its noise gate in USB mode is far too aggressive for my liking. Moreover, you are going to miss out on some features if you only use it in XLR mode.
In fact, this mic does feel like it's out here making a stand all on its own. I'm not saying Razer needs to make a rival to the RodeCaster Duo with all its bells and whistles, but a microphone like this is screaming out for a Synapse-compatible companion mixer. If Razer wants people to buy into its ecosystem, what does it want people to pair its XLR microphone with? I think it's time for a revamped audio interface, please, Mr Razer man.
Unfortunately, the mic market is really competitive. For an XLR option on price, the V3 Pro is sort of on par with the Shure MV7+ and Rod PodMic USB when ages, prices, and discounts come into play. Equally, the mic market has a Maono problem right now because, for paying less money, newcomers with lesser budgets could get the PD200W for far less and get great quality and a wireless connection.
I really, really like Seiren V3 Pro, and would happily use it for my own content. I'm not such a big fan of its reliance on Synapse, and if that's a problem for you too, I'd maybe steer clear of it. As a Shure alternative with excellent sound and an okay price, it doesn't get much better than this.
How I tested the Razer Seiren V3 Pro
I've used the Razer Seiren V3 Pro as my main microphone for all gaming, content creation, and work meets for around two weeks now. I mounted it to my boom arm, plugged it into the RodeCaster Duo, and adopted it as part of my setup. I compared it closely to my daily driver, the Shure SM7dB, using it in the same ways and using it with the same settings through my audio interface.
I recorded plenty of audio samples and listened back to them, testing various ways in which the mic acts and reacts to different use styles. I also tested across different PCs, using a USB connection with a laptop to test out all of Razer Synapse's extras.

One of my earliest memories is playing SuperMario64 and wondering why the controller I held had three grips, but I only had two hands. Ever since I've been in love with video games and their technology. After graduating from Edinburgh Napier University with a degree in Journalism, I contributed to the Scottish Games Network and completed an Editorial Internship at Expert Reviews. Over the last decade, I’ve been managing my own YouTube channel about my love of games too. These days, I'm one of the resident hardware nerds at GamesRadar+, and I take the lead on our coverage of gaming PCs, VR, controllers, gaming chairs, and content creation gear. Now, I better stop myself here before I get talking about my favourite games like HUNT: Showdown, Dishonored, and Towerfall Ascension.
