A fair while ago, Razer sent over their Seiren microphone for me to take a look at. So over the past few weeks i have been doing a lot of talking to see just what it can do.

Big thanks to Razer for sending this out for review.

Design and First Impressions

In the box of your new Seiren come the microphone itself, a 5m USB A to Mini B cable, the microphone stand, some Razer stickers and some documentation.

Upon first impressions, this is a BIG microphone coming in at 19cm long and 7cm wide. It has an all aluminium construction apart from the base which is plastic. It has perforated metal grills all around and foam underneath the help with noise cancellation.

On the back of the microphone is the Razer logo, the gain knob and the polar pattern knob, on the front is a small screen which displays the headphone out volume, the current polar pattern and the gain level.


On the base of the microphone is the USB port, a button that only seems to turn off the illuminated Razer logo and a standard microphone stand threading which also doubles as the mount for the optional Razer pop filter.


The Razer Seiren has 4 recording modes,

Cardioid Mode

Cardioid Pattern Desktop Large 1

Perfect for podcasts, game streaming, vocal performances, voice-overs and instruments. Cardioid mode records sound sources that are directly in front of the microphone, delivering rich, full-bodied sound.

Stereo Mode

Stereo Pattern Desktop Large

Uses both the left and right channels to capture a wide, realistic sound image—ideal for recording acoustic guitar or choir.

Omnidirectional Mode

Omnidirectional Pattern Desktop Large

Picks up sound equally from all around the mic. It’s best used in situations when you want to capture the ambience of “being there”.Like recording a band’s live performance, a multi-person podcast or a conference call.


Bidirectional Pattern Desktop Large

Records from both the front and rear of the microphone—good for recording a duet or a two-person interview.

All of these settings are changeable by the hardware knob on the backside of the microphone, none of this software rubbish.

Super Easy Setup

The Seiren is extremely simple to setup. Just plug on end of the cable into the Seiren and one into your USB port and your ready to go. No need to download drivers!

You can easily adjust the gain via the gain knob on the back of the microphone.

Here is a sample of the audio from the Razer Seiren with nothing changed, just base line audio.

I know, before i get inundated with emails, I know this is the older model. But it’s still a really good mic and hopefully soon i can get my hand on a newer model to try out.

Buy one from… I can’t actually find anywhere that doesn’t say “Discontinued”

Well, buy the newer and most likely better one from Razer
