The Cooler Master MH751 are basic wired gaming headphones. They have a comfortable fit, a well-balanced sound profile, and a detachable boom microphone that offers excellent recording quality. That said, they feel slightly cheaply made, don't have any sound customization features, and block out very little ambient noise. Otherwise, if you're looking for a pair of simple over-ear headphones with a high-quality mic, they're a good option.
Our Verdict
The Cooler Master MH751 are very good for neutral sound. Their sound profile is quite well-balanced overall, with impressive bass accuracy and a flat and even mid-range that yields full-bodied, present, and detailed vocals and lead instruments. Unfortunately, they struggle to deliver audio consistently and don't have any sound customization features.
- Well-balanced sound profile.
- Comfortable to wear.
- Can struggle to deliver audio consistently.
- No sound customization features.
The Cooler Master MH751 are poor for commuting and traveling, though this isn't their intended use. They block out very little ambient noise, especially the rumble of bus and plane engines, and aren't very portable. They also lack any sort of on-board controls for media playback or call management. That said, they should be comfortable enough to wear for extended periods.

The Cooler Master MH751 are a poor option for sports and fitness, though they aren't designed for this purpose. They do a middling job of staying in place and are quite bulky. They have a limited control scheme, so you may need to pull your phone out to make playback adjustments. Their wired connection also increases the chance of the audio cable snagging on something and pulling the headphones from your ears.

The Cooler Master MH751 are middling for office use. They don't block out that much ambient noise overall, and due to their wired-only connection, they lack any sort of handy wireless features like multi-device pairing. However, they're decently comfortable and don't leak all that much noise, while their boom mic can be detached to give them a slightly more professional look.

Their boom microphone makes your voice sound clear, full-bodied, and natural, and it doesn't struggle too much with isolating speech from background noise.
