Testing the Razer Seiren X
After unpacking the Razer Seiren X and plugging it into my PC, I immediately measured the distance from my keyboard to the location of the microphone that I placed it in. For testing, I measured 20cm directly back from the space bar on my keyboard. I decided to do this because I felt as if most gamers leave their microphone at approximately this same distance.
Keeping the microphone in this same spot, I recorded the dB (decibel) the Seiren X picked up through Open Broadcaster Software (OBS). It should be noted that throughout my testing, I had my Windows microphone volume set to 75. Why 75? Well, at 100, the Seiren X was picking up almost everything in my test environment, and to ensure a sterilized and fair test environment for the following tests, I had to reduce the volume.
Moving along, I then proceeded to measure the distance from the microphones location to my PC, which is located on my desk next to me. The microphone was placed precisely 45cm away from my PC case (be quiet! Dark Base Pro 900 Rev 2). I then turned the cases fans up to max and measured the dB. The Razer Seiren X was picking up a fluctuating -50 to -45 dB. These test results will not be the same for every user and are more of an approximation due to every user having a different PC case, different desk material, extra fans for more cooling, etc.
For my next test, I kept the Seiren X in the same location on my desk and then measured the distance between the mic and my ceiling fan. The fan is located 2m away from the mic. I then proceeded to turn the fan on its lowest setting and record the dB the airflow was producing. The Seiren X picked up -58dB, which is barely anything at all. I was extremely impressed by this, as airflow from fans can be a problem for some microphones.
