Razer Seiren Review

Razer Seiren Review

Razer are not afraid to dabble in new areas and have been known to look to the expertise of others when designing a new product. The Razer Mako for example were based on a THX design, not a bad place to start! Now with their latest addition they look to Blue and their Yeti mics. This is our Razer Seiren Review.

Razer Seiren Review – Packaging and Bundle

Razer package the Seiren in a high quality box which gives us a nice clear image of the product on the front. Inside the mic is suspended in a large amount of premium foam padding with the bundled extras in a separate compartment. Those extras are documentation, stickers and a USB cable.


Razer also offer a couple of optional extras for the Seiren. The first is an aluminium shock mount which allows us to attach the Seiren to a stand, minimising vibrations and noise. Also available, again to minimise noise is a pop filter which reduces Plosives and Sibilance from the user pronouncing P’s and S’s. Breathing sounds are also reduced by the filter and it can mount on the mic itself, or on the shock mount.

Razer Seiren Review – The Seiren

There is no doubt that the Razer Seiren stands out in any environment. The large black design with silver highlights looks great and it is predominantly metal that is used here. The stand too is a large chunk of metal with a softer base that keeps it stable on our desk. The two bolts on the side of the stand allow us to create some tilt (or completely remove) and there is a LED lit Razer logo on the side of the mic which will face a camera when streaming.

Below that Razer logo are two dials. One controls the gain of the mic and the other the pattern used to pick up sound. Razer allow four patterns, using the three 14mm condenser capsules inside:


Looking round to the other side of the mic, the one which faces us, we have an OLED display which gives us detail on the pattern in use as well as the level for the last used dial, gain, or the headphone output that is below the display, above the mute button.


Speaking of the headphone output, this is designed as a monitor which will allow us to hear what the mic is outputting however it also passes through audio from our PC so can be used as a standard audio out. What else is on the bottom surface? We have the USB connector, a port to which we can attach the pop filter or shock mount and then a button to disable the Razer LED.

As far as specifications go, the mic requires a 5v/500mA USB port and has a sample rate of 192kHz with 24bit bit-rate. Frequency response is 20Hz to 20kHz, sensitivity 4.5mV/Pa (1kHz) with max SPL of 120dB (THD: 0.5% 1kHz). For the headphone amp impedance is >16Ohms, THD 0.009%, power output (RMS) 130mW, Frequency response of 15Hz-22kHz and signal to noise ratio of 114dB.

Razer Seiren Review – Software


Razer require that we install their Synapse software when setting up the Seiren and part of that process installs the required driver. Those who have it pre-installed for another Razer peripheral will get a quick update and then we are ready to go. Synapse allows us to control two aspects, bitrate and sample rate. For those who don’t like the control panel it can then be uninstalled, leaving the driver in place and the mic functional.

Razer Seiren Review – User Experience and Conclusion

Looking at the design and build quality of the Seiren first we have a product which very much impresses. The casing looks and feels very high quality and the sturdy, industrial themed stand only adds to this. The LED logo really does stand out in addition to this (so some will like the fact it can be disabled) and the mic is easy enough to position within the stand. Would we change anything? Maybe put some rubber on the dials to give them a slightly nicer feel and some extra grip. Height adjustment on the desktop stand would be a real bonus too, but these are just nice to have aspects rather than issues.

Setting up the Seiren is very easy, plug it in, install the software and it is good to go. It would be good if Razer could update the panel to include some sound profiles though. We also need to make note of a Windows 10 quirk for anyone who is running the beta/preview. Out of the box the Seiren will not work with Windows 10 (yet). A basic driver is installed but the mic doesn’t activate. Additionally Synapse doesnt download and install the driver. However if you have access to a Windows 8.1 PC, install the Seiren on that, install the software and then head into the folder for the program. There you will find the stand alone Seiren driver installer. Run that on Windows 10 and the Seiren works flawlessly.

On the value front, it is possible to buy a mic of near identical specification from another manufacturer, and competing mics with very similar specs from others for less however the build quality and design isn’t up to the same standard as this Razer option. Enhanced software would help set Razer apart and bundling at least the pop shield would add the extra value needed to tip some people across the line we would suggest.

Sound quality on the Seiren is very good. Easily an improvement on the more commonly used headset mics and competing well with other units above £100/$150. That said, the various patterns which can be selected will likely be used by few (better to have and not need than need and not have?) but for the most part it will be all Cardioid mode. With this enabled the sound is plenty crisp, loads of detail too and a decent flat profile which could be accused of leaning a little towards the lower end which we can work with in post. Users need to be aware though that Windows mic level of 50% and gain of about 30% is about all you will ever need. Past that and things get too loud for most uses. The mic is also not forgiving of background noise, even in Cardioid pattern. If this is to be used in a room with fan noise, keyboard noise, co-workers, a tv… all will be picked up and broadcast by the Seiren. This is potentially another area where Razer could enhance their software, offering noise reduction tech.

Above sound test recorded in near silent room, minimal fan noise, no other person in the room. Pop filter on.

Summary: The weakest aspect of the Razer Seiren for many will be its value proposition, potentially followed by the lack of options available in the software. That said, the build quality and design of the Razer Seiren are excellent and the audio quality is very good indeed.
