Cooler Master MH650 RGB Gaming Headset

Cooler Master MH650 RGB Gaming Headset 5

To complete and strengthen its gaming headset offer, Cooler Master has released 3 new products, the MH630, MH650 that here we have  the MH670.

The Cooler Master MH650 RGB is a mid-range gaming headset; it is also the only one of the MH series to have RGB, but RGB is not abundant either, but the simple touch of RGB will appeal to retro fans, lighting.

The MH650 is a wired headset dedicated to gaming with 7.1 sound, a sober design and rather lifestyle-oriented, only the touch of RGB will suggest the opposite.

Now let’s move on to the unboxing of the Cooler Master MH650; as usual at Cooler Master, we find quality packaging, on the front of the box, we find a photo of the model as well as some information on it, such as that the connection in USB-A or USB-C, the compatibility of the product and the mention RGB. We notice the same information on the back of the box, but they are more detailed by the manufacturer.

We find the headset and the microphone, which, yes, is a non-integrated microphone, which is very practical during long gaming sessions without a microphone or for simply listening to music so as not to be disturbed by the microphone if it is not used.

But that’s not all; there is also a soft velvet protective cover to protect your helmet as much as possible when travelling. The last accessory, which makes me extremely happy, you probably guessed it, is a USB-A to USB-C adapter.

This accessory seems really practical to me, where we see more and more portable or stationary computers with USB-C, like me who uses a stationary computer under Windows to play big games and who need the USB-C adapter for my MacBook Air M1 for playing smaller games, for writing tests or for long Discord or Teams sessions with the editorial staff.

Let’s talk about Cooler Master, let’s talk about design, here the headset is very simple, and it does not overdo it, the whole headset shell is matte black plastic, but at the same time, Cooler Master is trying to offer something more thanks to the RGB present around the horns of the two ear cups. As we have seen, the main material is plastic, apart from the skeleton of the arches made of aluminium.

In terms of user comfort at the level of the buttons, this is good; they fall easily to hand; on the left side, we find the essential buttons, i.e. the volume wheel and the On / Off button of the microphone. On the right, we find the buttons for 7.1 sound and the backlight button.

The Cooler Master MH650 very well meets our expectations of a helmet under $120; the helmet is not the heaviest but does not reflect a cheap aspect; it is only done with minimal feeling in the long run.

In terms of comfort, which is nevertheless an essential component of a headset, you will understand that we are entitled to expect from a gaming headset at this price, in general. The headset will revive more than one.

Audio Quality

Let’s talk about the most basic part of headphones, the sound. To start with the video games part, what the headset is designed for, it does well, even very well, on CS: GO, for example, the steps and actions of our enemies are clearly audible even from a distance, despite a slight lack of volume, but which does not bother more than that.

In-game, the sound is good, well redistributed and correct; you will not have a start because of a sound that is too loud, which can be appreciable to have better reflexes to eliminate your opponents who are behind your back as quickly as possible.

As for the sound quality in music, we mainly used Apple Music, which delivers excellent audio quality, despite the compressed sound, except in lossless. 

We see that the sound is good, dynamic, the bass is a little present, but above all, the sound is rather rich and very pleasant for listening to music. We quickly notice that we are on a gaming headset but with potential use as a musical headset from time to time. To conclude on the sound quality, in music, the midrange and treble are correctly transcribed; unfortunately, the bass is too little present for my taste, but it still does the job very well and will satisfy most users.

Microphone- The microphone is good; it does not saturate during high-frequency sound; it has the advantage of being detachable because this allows it not to take up space visually for nothing.

The only problem with the microphone is that we hear the little background noises that are not essential and, above all, not necessarily the most pleasant.

In terms of connectors and buttons, we find on this Cooler Master MH650 :

  • 7.1 sound activation buttons
  • Mute buttons
  • RGB activation buttons
  • Volume buttons +/-
  • 1 x 3.5mm Jack Port
  • 1 x Power LED

The buttons and connectors are more than sufficient for all kinds of uses, which the gaming range allows.

There are fabric headliner covers and a fabric headrest; the fabric prevents sweating and is soft enough not to hurt the ear contours. Even if the fabric does not sweat more than that, you can remove them to wash them separately from the frame.


The Cooler Master MH650 is a good gaming headset, comfortable and efficient; it revived all users. Note that this is the only MH series to have RGB, but not in large quantities. The microphone is efficient but too easily picks up ambient sounds. And the audio is good, but it lacks bass.
