Now that that’s out the way, starting off with the sound right off the bat, the MH650 is a very loud headset. So loud in fact that you could place this on your desk, increase the sound on your PC to 100% and use the headset as a set of speakers. We do not recommend using the headset with the volume maxed out while it’s on your head. It’s very loud and prolonged usage like this will most likely damage your hearing.
A consequence of the loudness is that even though this is a closed-back headset, sound leaks out of it into your environment. If you’re playing music with the volume turned up, and someone else is nearby, they’ll definitely hear what you’re playing.
Coolermaster have opted to keep the headset volume control separate from your PC volume control. So fundamentally while you can control the volume on the headset itself by moving the volume control up or down, you will still need to adjust your PC sound settings too. While typing this review and listening to music, I’ve had the sound maxed out on the headset itself while my Windows PC audio is set to 2%. Yes, you read that correctly, 2%… Bumping it up further, past around 30% or so, starts really outputting way too much sound for daily general usage or even gaming. This headset has a heck of a kick.
The “Virtual 7.1 Surround Sound” can only be used with a PC and once you have Cooler Master’s MasterPlus software installed.
Kudos to Cooler Master here since the headset headband really is quite comfortable.
...the flashing red lights are ridiculously obnoxious and it’s shocking that this cannot be disabled.
