The Cooler Master MH630 are decent wired gaming headphones. They're fairly comfortable for long gaming sessions and their superb detachable boom microphone records voices very clearly so you won't have any problem being understood by your teammates or friends. They also have an excited v-shaped sound profile, but they can sound overly boomy and bright and without dedicated companion software, you won't be able to easily tweak them. They also have limited controls and block out almost no background noise.

Our Verdict

5.2 Mixed Usage

The Cooler Master MH630 are disappointing for mixed use. Although they're fairly comfortable wired gaming headphones, they aren't designed for more casual use. They block out almost no background noise like bus engines or office chatter, they aren't stable enough for even moderate exercise, and their bulky design makes them difficult to take with you on-the-go. Their excited v-shape sound profile may please some listeners but the lack of dedicated companion software is disappointing. However, their boom microphone is one of the best we've tested so far for gaming headphones.

Pros
  • Superb mic recording quality.
  • Detachable boom microphone.
  • Comes with a PC Y-splitter.
Cons
  • Limited controls.
  • Poor noise isolation performance.
  • No companion software.
6.7 Neutral Sound

The Cooler Master MH630 are fair for neutral sound. They have an excited v-shape sound profile that's very boomy and bright. However, they lack dedicated companion software so you can't EQ them. Their soundstage is also mediocre and although it sounds wide and somewhat spacious, audio still seems like it's coming from inside your head.

4.4 Commute/Travel

The Cooler Master MH630 are bad for commuting. They're fairly comfortable for longer listening sessions, but they block out almost no background noise like bus or train engines. Their bulky design also makes them difficult to take with you on-the-go. Still, their lack of a battery eliminates the worry about recharging them before using them.

5.1 Sports/Fitness

The Cooler Master MH630 are poor for sports. As they're designed for gaming, they have a bulky design and aren't very stable on the head, especially if you're wearing them during intense physical activity. While they're fairly comfortable, their audio cable can snag onto things and pull your headphones off, especially if you're using their cable lock feature.

4.9 Office

The Cooler Master MH630 are poor for office use. Although they're decently comfortable, they isolate almost no office noise at all, and at higher volumes, also leak audio, which can be audible to your workmates around you. On the upside, they don't have a battery, so you don't have to worry about recharging them.

5.1 Wireless Gaming

The Cooler Master MH630 are wired gaming headphones and can't be used wirelessly.

7.1 Wired Gaming

The Cooler Master MH630 are decent for wired gaming as they're compatible with most consoles that have an audio jack. They're decently comfortable, have negligible lag thanks to their wired connection, and their boom microphone captures voice clearly, even in louder environments. On the downside, some may find their bass too boomy and without a companion app, you can't EQ or customize them.

7.2 Phone Calls

The Cooler Master MH630 are decent for phone calls. They have an exceptional boom microphone that captures your voice clearly, even in noisy situations. On the downside, you may have trouble hearing the person on the other end of the line if you're talking in a noisy environment as they block out almost no background noise around you.

Style

The Cooler Master MH630 have an understated, all-black plastic design. Parts of the headphones, like the headband, look and feel cheap. On the bright side, the braided cable and detachable boom microphone stand out as more premium features that help to transition them from gaming to more casual settings.

The Cooler Master MH630 are fairly comfortable gaming headphones. Their padding on the ear cups and headband is okay but it feels a bit mushy. They also have a decently tight clamp on the head.

Like most gaming headphones, the Cooler Master MH630 are bulky and aren't very portable. While their ear cups can swivel to lay flat, they still have a big footprint and need to be stored in a bag when you're on the go. However, as these are gaming headphones, you likely won't be moving them all the time.

The Cooler Master MH630 have a poor carrying pouch. It's made of thin, black velvet but it won't really help to protect your headphones from anything but dust or dirt.

Build Quality

These headphones have an acceptable build quality. The plastic ear cups feel cheap while the cloth padding on the cups and headband seems like it can flatten over time. However, these headphones use a braided cable and have a detachable boom microphone, which makes them feel more sturdy and less prone to breakage.

Design
Stability

The Cooler Master MH630 aren't very stable headphones. As they're not designed for sports use, they can fall off your head with vigorous movement. While the cable is detachable, there's a feature to lock it in place and if the cable is snagged on anything while you have it locked, your headphones can still get yanked off your head.

These headphones have an excited v-shape sound profile. They deliver serious punch and boom, although some may find it sounds too boomy. They also have a very bright treble range, which can be piercing and shrill.

Frequency Response Consistency
Avg. Std. Deviation

The frequency response of the Cooler Master MH630 is passable. Bass delivery can slightly vary and a drop in bass may occur if the ear cups are not flush to your head, especially if you wear glasses or have thick hair. There are also some inconsistencies in the treble range and they seem to be sensitive to positioning and placement.

These headphones have satisfactory bass accuracy. While they lack a bit of thump and rumble in the low-bass, they're a lot more over-emphasized in the mid to high-treble. There's a powerful punch and warmth in their sound but this may be too boomy for some listeners.

The mid accuracy performance of the Cooler Master MH630 is superb. The mid range is neutral sounding, resulting in a well-balanced production of vocals and lead instruments. The high-mid is slightly over-emphasized but shouldn't sound too harsh.

The treble accuracy is poor. The whole treble range is over-emphasized which makes vocals and lead instruments sound harsh and painful. Sibilants such as S and T sounds are also piercing.

The peaks and dips performance of these headphones is reasonable. There's a huge peak in the high-bass, making your mixes sound boomy and muddy at the expense of vocals and lead instruments. They're further weakened by several dips within the mid-range while the following peaks in the treble range make sibilants like S and T sounds in vocals piercing and painful.

The stereo imaging is great. While there are a couple of very small peaks in the bass range, the group delay response otherwise falls below the audibility threshold, resulting in a tight bass and a transparent treble reproduction. Additionally, the L/R drivers of our test unit are exceptionally matched, which is important for the accurate placement and localization of objects and instruments (like voices and footsteps) in the stereo image. However, these results are only valid for our unit and yours may perform differently.

The passive soundstage is mediocre. As these headphones have a closed-back design, they won't produce as open or spacious of a soundstage as open-back headphones. Still, the soundstage sounds wide and somewhat natural but is perceived as coming from within your head.

The Cooler Master MH630's noise isolation performance is poor. It doesn't reduce any bass-range sounds, which isn't great for commuting as you can still hear all of the rumble created by bus or train engines. It also doesn't do much for mid-range sounds like chatter and while it can help cut higher-pitched sounds like A/C noise, it may not be enough for some listeners.
