Microphone Performance

The microphone of the Cooler Master MH751 was tested by connecting it to the ASUS ROG MAXIMUS XI Formula motherboard and Creative Sound Blaster E1, a $50 external USB sound card. To review the microphone's sound and compare it to other similar headsets, I used the Adam A7X speakers and Shure SRH840 headphones, both being studio monitors, connected to Audiolab's M-DAC, a high-quality digital-to-analog converter that functions as an external sound card when connected to a PC. Testing was done in Discord, TeamSpeak, Skype, and Audacity, and I also used Audacity to record sound from the microphone. The sound was recorded with microphone sensitivity set to 100% (unless stated otherwise) and was not post-processed or edited in any way.

For reference, this voice recording has been made with the Rode NT-USB, a high-quality studio microphone:



This is the sound sample recorded by using the omnidirectional, detachable microphone the Cooler Master MH751 comes with:




As you can easily hear, the microphone quality of the Cooler Master MH751 is excellent. My voice sounds perfectly clear, airy, and very natural, which is rarely the case in this price category. In fact, many more expensive gaming headsets don't offer a microphone of this quality, which you can clearly hear by listening to the following samples.






I'd argue that the microphone of the Cooler Master MH751 sounds almost as good as that of the Sennheiser GSP 301, which up until this point, I considered to be class-leading in terms of clarity, naturality, and dynamics. Another interesting thing to note is that the microphone of the Cooler Master MH751 sounds better than the microphone of the more expensive Cooler Master MH752 even though they're the same. You can hear it by listening to the following samples.




What's happening here is simple: the USB sound card the MH752 is equipped with has worse microphone input than the sound cards I use for sample recording (the external Creative Sound Blaster E1 and SupremeFX S1220 chip integrated on my motherboard). What you hear here is the difference between sound cards, not microphone capsules. You might find this interesting should you have ever wondered about the impact a sound card can make on the way your microphone sounds.
