Testing & Performance
To test the Cooler Master MH320 Headset I choose to use the testing suite at http://www.audiocheck.net/soundtests_headphones.php. It has a wide range of test to determine the just how well your headset performs. Also, I want to add I'm almost 40 and with age hearing loss comes in one way or another. So, I set the volume on the headset to 100% and my computer master volume to 30. This level of sound should work well from all test.
Is a two-part test with sound files testing the bass and treble extensions. The bass extension tests your headphones 10 Hz to 200 Hz and the treble extension test your headset 22 kHz to 8 kHz. Good headphone will go as low as 20 Hz on the bass test and will have frequencies up to 20 kHz.
The bass test I could hear the frequency just after the 20 Hz was announced so the test was good.
The treble test I could hear the frequency about at 17 kHz. This is lower than good headphone rating but I might add age and past work history will have an effect on the test.
The dynamic range test goes between the quietest and loudest signals in which this case is white noise to speech telling you how far below dBFS (decibels below full scale). The test is not related to a specific function of the headset, but it helps to test isolation within a noisy environment.
I personally could hear the Voice Over speech as low as 66 dBFS.
The quality test tests the bass frequencies to check how well the speakers are made. If they are poorly made they will have a rattling or buzzing noise.
The headset had no buzzing or rattling.
The driver matching reproduces a stereo frequency to both earpieces at the exact identical level. The tone should feel as though it is right in the middle of your head.
The headset was perfectly matched through the whole test which was up to 10 kHz.
The wiring test checks to make sure the left wiring is connected to the left headphone & the right wiring to the right headphone.
The wiring was connected correctly.
The binaural test has two sets of wooden door knock. The recordings were captured by having a microphone in someone's ear so that it collects the sound that reaches the pinnae, the external part of the ear. This works only with headphones and you are determining whether the sound is right next to you and how real does the wooden door sound.
This is my favorite test. I have to prepare myself for how realistic the sounds I'm about to hear are. I'm happy to say the sound quality from this test was wonderful.
To test out the microphone and not rely on another person's thoughts I simply recorded myself at different outputs levels.
The microphone recorded great in the playbacks.
