Aesthetics & Build Quality

The MH670 has a clean-looking aesthetic and is finished in black all around, save for the Cooler Master logos on the ear cups that come in a gunmetal grey colour. 

Given the headset's understated appearance with no RGB LEDs or flashy visuals of any sort, one would be forgiven for mistaking the MH670 for professional studio headphones instead. Its versatile appearance would mean that one could potentially use the headset for gaming, school and work contexts.

Size adjustments are possible for the headband, naturally, where it has a stainless steel core and is pretty flexible so as to aid with wearing comfort. The foam padding for the headband is nice and soft to the touch, and has a PU leather outer layer.

Likewise, the earpads are nicely padded and made out of foam and PU leather as well. The earpads are removable, and can be replaced if you’d like to use third-party ones instead.

On the left earcup, we get the port for the MH670's detachable microphone (the port has a protective rubber flap), a 3.5mm audio jack for when you’d like to use this headset in the wired mode, a microphone mute button, as well as a volume control wheel. 

Over on the right earcup, we get the power button for the headset, a power and charging indicator LED, a micro USB charging port, as well as a button to enable and disable the 7.1 surround sound feature on the fly.

The MH670 sports a detachable microphone that connects to the headset via a 3.5mm audio jack, where attaching and removing it from the headset can be done in a jiffy.

Wearing Comfort & Usage Experience

In terms of usage comfort, I played some games for about an hour or so with the headset on the wireless mode, and I’m happy to report that wearing comfort is pretty decent right out of the box, despite the fact that I wear glasses, where the force that the headband exerts seems to be just about right, so as to ensure a secure yet comfortable usage experience.

While using the MH670 on the wireless mode, I found its sound signature to be pretty good, at least to my non-audiophile ears. Out of the box without any adjustment to equaliser settings, I found the audio profile to be on the bassier side of things. Volume levels were pretty good, and I had a blast using this headset for games, listening to music and watching movies. Do note though, that using the MH670 on the wireless mode does reduce the frequency range of the headset, where the supported frequency range becomes 20 Hz – 20000 Hz on the wireless mode instead of 15 Hz - 25000 Hz on the wired mode.

That said, Cooler Master has an optional MasterPlus software that is pretty easy to use, where you get a sound tab pictured above with customisable equaliser settings, and three preset sound profiles for you to choose from. I found the default Gaming (Bass+) setting to be my preferred sound profile of the lot - Gaming (Bass+) is also the default sound profile should you wish to use the headset without the MasterPlus software. You do of course get the option of creating and saving your own sound profile as well. As of the time of writing this article, the MasterPlus software is available only for Windows PCs.

The MH670 sports a virtual 7.1 surround sound feature that can be tweaked within the same MasterPlus app - again, due to software limitations, this surround sound feature is only available on Windows PCs. Within the app, end-users have the option of manually tweaking the positions of the virtual "speakers" to your heart's content, and thereafter saving these settings via custom sound profiles. I found that when the surround sound feature was enabled, the soundscape of the MH670 became much more immersive, with little details such as distant footsteps and gunshots becoming more discernible so as to aid with your gameplay.

Moving on to microphone quality, the headset's detachable microphone performs pretty well, and will definitely get the job done when it comes to gaming with friends, or even taking conference calls for school or work. For an audio sample, do refer to the YouTube review video at the top of this article.

Conclusion & Pricing

In conclusion, the Cooler Master MH670 wireless gaming headset has held up well against the test of time, where it sports a no-nonsense aesthetic, has good build quality, and more importantly, serves up an audio experience that is great for gaming, music and movies.
