Microphone Performance

The microphone of the Cooler Master MH752 was tested by connecting it to the ASUS ROG MAXIMUS XI Formula motherboard. 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 MH752 comes with:



The microphone quality is decent, although not great. You can easily hear that my voice sounds compressed and grainy. What's interesting is that the microphone capsule isn't to blame as it's capable of offering a much higher microphone quality. You can hear it by listening to the sample I recorded with the Cooler Master MH751, which uses an identical microphone.



When I plugged the microphone of the MH751 into the MH752, it sounded the same as in the first sample. That leads us to an obvious conclusion: the USB sound card supplied with the MH752 has mediocre microphone input.

While the microphone of the Cooler Master MH752 is perfectly usable for communicating with your friends through Discord or Skype, I wouldn't consider it for anything more serious than that, such as Twitch and YouTube streaming. However, the microphone of the analogue MH751 is definitely good enough for that when plugged into a decent sound card, which is kind of confusing when you consider that it's the same microphone, but you hopefully get my point.

Finally, let's listen to a couple of microphone samples recorded on some other USB headsets the Cooler Master MH752 would likely compete with, just so you know what you can expect from them.
