The setup process is pretty easy for each headset, although each is a bit different. For the MH630 you want to plug in the 3.5mm cable to the headset and either connect it directly into your device or use the split cable to connect to separate headset and microphone jacks.
For the MH650, just plug in the USB cable and windows will automatically recognize it and it will show up under audio devices.
For the MH670 be sure that it is charged up first. Then plug in the USB dongle to an open USB port. Power on the headset and it will show up under your audio devices.
Comfort is definitely an important thing when it comes to a gaming headset. No matter how good a headset sounds if it is not comfortable you are not going to use it. All three headsets are designed pretty much the same with the exception of the MH670 which opts for PU leather over fabric for the earcups and headband. I feel that each headset is very comfortable, Cooler Master has added just the right amount of foam to be comfortable but not annoying over time. I had many multi-hour gaming sessions using the headsets and when I took the headset there was not any discomfort. I would have to say the MH670 is the most comfortable out of the three as I prefer the PU leather over the fabric, and I feel it does a better job at noise cancelling.
So now getting into how these headsets actually sound. All three headsets use the same 50mm Neodymium drivers. These drivers will give you a frequncy response ranging from 20 to 20,000 Hz in USB or wireless mode and 15 to 25,000 Hz in wired (3.5mm) mode. Given that each headset does sound very similar. All three headsets are pretty bass-heavy, which most gamers should appreciate. Out of the three the MH650 does sound the best in my opinion, more than likely because it is louder than the other two. That is not to say the MH630 and MH670 aren’t plenty loud. I was actually surprised how loud the MH670 was in wireless mode. Too many times I’ve reviewed wireless gaming headsets that just weren’t loud enough.
The MH650 and MH670 offer 7.1 Virtual Surround Sound. I tested this feature in games like Apex Legends and Cyberpunk 2077. This virtual surround sound really only seemed to boost the sound and make it a bit clearer. Many times I would toggle it on and off and it would really be hard to tell the difference. For me Cooler Master’s implementation of virtual surround sound was not as good as what we’ve seen from HyperX and Razer.
When it comes to microphone quality I was quite impressed with both the MH630 and MH650. My voice sounds very clear and has noticeable depth to it. This quality is much better than many of the previous gaming headsets we’ve tested. Now the microphone on the MH670 is less impressive, as you can tell the audio is compressed. This is typically the case with wireless gaming headsets. Check out audio samples below of the microphone on all three of these headsets as well as some of the latest gaming headsets we’ve taken a look at.
