I’ve read and heard many great things about Cooler Master MH751. Supposedly, this gaming headset sounds very neutral and it’s great for music too. I was anxious to test those claims myself so let’s dig into it. 


First of all, let’s cover looks and build. They come in the great big black box that looks as luxurious as it gets. With headphones, you get a two-piece cable that is detachable. The first part has an inline volume control and mic mute button. It has a 4-pole plug and it will play along nicely with most phones and laptops. The extension part divides microphone and headphones into two traditional 3-pole connectors so you can plug those to any sound card, DAC, amp, etc. The headphones themselves are built quite nicely. Matt plastic has some kind of soft-touch finish. The headband padding is nice and soft, while the grip is not strong but keeps them in place nicely. Ear-pads are thick and so soft that these are probably the most comfortable headphones I have ever worn. They certainly get credit for that.


But let’s talk sound. Bass is not overblown at all, it’s decently precise but not that fast and accurate actually. Mid tones are clear but kind of thin and detached from the bass. Vocals are mostly dominated by the pronounced higher midrange and quite hot highs. While I listen to acoustic instruments and vocals I know very well – they all sound thinner and sharper then they should. The only part of the spectrum that actually has fullness and fluidity is bass.

I hooked them to several different sources – my integrated amp, several DACs, and smartphones… The aftermath is always the same – decent bass but thin vocals and other mid-tones. They’re heavily influenced by hot highs giving you that rustling quality. On the positive note, the soundstage is decently wide. 


Next, I pulled out my AKG K92s and immediately noticed the much fuller sound. There is more mid-bass juice here to connect bass and mid-tones into a whole. High tones have more fluidity. Voices are kind of tube on K92 but overall these produce bigger and lusher sound. Going back to Cooler Masters you can’t shake the feeling that sound lacks body and fluidity.

Compared to HyperX Cloud Alpha these have a much more realistic bass level and I appreciate that. HyperX, on the other hand, does almost everything else better. They offer fuller and sweeter mids, cleaner highs that don’t leak into mids making them artificially sharp, better separation, and soundstage. The only real downside of the Alphas is that over-bloated bass.  Still, I would rather choose them over Coolermasters to enjoy my music.


Cooler Master MH751 is the most comfortable headset I’ve tried recently. They feel so nice on my head that I really wanted to like them. But in the end, I’m not a fan of their bright and sharp sound. Those are not the qualities I appreciate when listening to music. On the other hand, they might be perfectly fine for gamers – users they’re actually aimed at. They do offer a mix of build quality, usability, and great comfort. I certainly wouldn’t blame anyone for getting them for those reasons.
