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. Plus, without dedicated companion software, you can't 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 mic has an excellent overall performance suitable for gaming.

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. Unfortunately, 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.

Compared To Other Headphones

Comparison picture

The Cooler Master MH630 are decent wired gaming headphones. Unlike many other gaming brands, they lack companion software that can help tweak their sound, and their controls are limited. However, their detachable boom microphone has a superb recording quality, and their fairly nondescript look makes it easy to transition these headphones from gaming to a more casual setting.

If you're shopping around for more gaming headphones, check out our recommendations for the best gaming headsets, the best gaming headsets for the Xbox One, and the best wired headphones.

Cooler Master MH751

The Cooler Master MH751 are better gaming headphones than the Cooler Master MH630. The MH751 have a better-balanced sound profile, block out more ambient noise, and leak less audio. Meanwhile, the MH630 have a slightly better boom microphone and deliver audio a little more consistently.

HyperX Cloud Stinger

The HyperX Cloud Stinger are better-wired gaming headphones than the Cooler Master MH630. The HyperX are slightly more comfortable, have a more neutral and better-balanced sound profile, and also have a longer audio cable. However, the Cooler Master's boom microphone has a superb recording quality, which may be more important to some gamers who rely on being heard as clearly as possible.

SteelSeries Arctis 1

The SteelSeries Arctis 1 and the Cooler Master MH630 are very similar wired gaming headphones. Both the SteelSeries and Cooler Master are fairly well-matched in build quality and comfort. They both also have limited controls and no companion software. However, the SteelSeries have a better-balanced sound, and they leak less sound, whereas the Cooler Master's microphone has a better recording quality.

Corsair HS60

The Corsair HS60 are better-wired gaming headphones than the Cooler Master MH630. They're more comfortable, have better build quality, and their sound profile is more neutral and balanced. The Corsair also have a companion software with a graphic EQ plus presets if you want to tweak the sound and they have a virtual surround feature. However, the Cooler Master's boom microphone has a better recording quality.

Logitech G533 Wireless

The Logitech G533 Wireless is a better gaming headset than the Cooler Master MH630. While the Logitech are wireless, they have a slightly more comfortable fit, a better balanced and neutral sound profile, and they offer virtual soundstage features. They even have companion software with a graphic EQ and presets as well as a 17-hour battery life, so you can play for hours without having to worry about recharging them. However, the Cooler Master's wired design makes lag not an issue and their boom microphone has a superb recording quality.

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.

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, making them feel more sturdy and less prone to breakage.

5.5
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. Consider the Cooler Master MH751 if you're looking for similar gaming headphones with a slightly more neutral sound profile.

The Cooler Master MH630's frequency response consistency is passable. Bass delivery can vary slightly, 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 fair 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 Cooler Master MH630's mid accuracy 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 peaks and dips performance 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. Also, 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.
