Last week we took a look at the MH650, the RGB LED edition of Cooler Master’s 2020 MH600 series of headsets. And as promised, today we are going to be looking at its wireless sibling, the MH670. This headset brings a different skill set to the game than the other units in the series, and as we go on I think you’ll see why this one is our favorite out of the bunch. As always, some specs before we begin:

  • 50mm neodymium drivers
  • 15-25,000Hz frequency response / 3.5mm mode, 20-20,000 Hz / 2.4G wireless mode
  • Steel and plastic headband with PU leather and foam cushion
  • PU leather ear cushions
  • Detachable omni-directional microphone with on-headset mute control
  • Multi-platform compatibility with wireless, twist and lock 3.5mm, and USB connectivity options
  • 7.1 virtual surround sound with on-headset control
  • Up to 25 hours battery life per charge
  • Fold-flat design
  • 373g (with 3.5mm cable), 346.5g (wireless)
  • Includes travel pouch, USB to USB-C adapter, 3.5mm and USB cables

Design and Functionality

In the MH600 line, each of the three headsets have their targeted specialties. The MH630 is great as an inexpensive entry-level gaming headset for folks just getting into personal gaming audio. The MH650 is great for streamers and podcasters that want to have a bit of flair, and still come in without assaulting your wallet. The MH670 drops the LED’s, but adds some premium upgrades and across the board, namely multi-platform compatibility with different choices for your audio interface. The first option is standard 3.5mm, which lets you plug into mobile headphone jacks, your desktop DAC units, and makes it usable for console gaming as well. The second is USB and USB-C, allowing a single plugin for your PC or modern USB-C mobile device. The third is wireless using a USB plug-in dongle. And because the unit comes pre-packaged with a USB to USB-C adapter, that means you can even run it wireless through a USB-C connection. Being able to remove the microphone turns them into headphones as well that would look as at home in a studio as they do next to your gaming rig.

That’s literally all the platforms I have. I used it in 3.5mm mode to plug into my PS4 controller, wirelessly using the USB dongle for my PC, and just for kicks used the wireless dongle with the USB-C adapter to test it on my Samsung Galaxy Note 9. This is why it’s our favorite model out of the MH600 trio – it offers you the flexibility to use it pretty much however you want. I’m a big fan of flexibility and like using standalone units that can multiclass (not unlike myself). And it comes in at under $120. Not a bad deal for a decent multi-use headset.

The MH670 has a sleek minimalist black design like the rest of the MH600 family, with a few additional features and upgrades. First, the mesh fabric and foam have been replaced with PU leather material for both the ear cups and the headband, giving the unit a more premium look and feel than the 630 and 650 models. The ears still fit nice and snug on your head, and can be expanded like the others to fit domes of most sizes. The thick cushioning on the ear cups can make it a bit tight but for the most part it’s comfortable to wear both in gaming session or on a conference call. It’s a good thing that the thick padding does squeeze a bit hard, because moving from wired to wireless adds some significant weight to the headset, and a loose headset with weight is a headset that falls off of one’s head. If we’re making comparisons sans cables, the MH670 weighs in at 346.5g up from the MH650’s 282g, almost a 23% difference in weight. That’s to be expected – a wireless unit has to have more electronics packed into it to make it go. The extra weight does make it a bit tougher to wear for hours at a time than the MH650, but CM did a good job in minimizing that.

Like the MH650, this model has all of the necessary controls on the headset itself (which really is required if you’re using it wirelessly). On the left ear you have a volume control dial, mute button, socket for the removable microphone, and a 3.5mm cable jack. The right ear has the on/off button, toggle for 7.1 surround, and the socket for the USB cable. All of the necessary cables come with the headset, and as we’ve come to expect from Cooler Master they’re braided and snag-free. All of this is easily portable with the included travel pouch.

The battery life on this headset is really a bright spot. I tried my best to time it out to see how long I can go without charge, and by my notepad math I got just about 20 hours before I had to plug it in with the USB to charge up again. The nice part is all you have to do is switch over from wireless dongle to USB direct and you can still use the headset while charging. The only downside here is that the MH670 doesn’t take advantage of USB-C fast charging, meaning getting it back up to full charge will take a couple hours. But truth be told, that’s still not that bad.

The Sound

Like the MH650, your sound can be customized through CM’s PORTAL software. It provides adjustments for 5 levels as well as dedicated bass and treble sliders as well. It comes with three pre-programmed profiles for pop music, movies, and gaming but you can save your own profiles as well. It also allows for more fine-tuning for the 7.1 surround sound, and storing profiles for the virtual speaker arrangement.

The headset provides great balanced audio like the MH650, and I can’t tell if it’s in my head but the high end chirps aren’t as muted on the 670 as they were on the 650. The highs of gunshots rang clear in the John Wick Red Circle scene without losing any of the lowline bass, and that was the “gaming” pre-loaded profile in the PORTAL software. It felt like the sound was more balanced low to high than the MH650, The virtual 7.1 served very well for grand-scale action flicks like Avengers: Infinity War and Endgame for the big battle scenes.

While I was test driving this unit, Final Fantasy VII Remake was released so I left the current Diablo III season to run console style for a bit plugging into my PS4 controller with the 3.5mm cable. Again, the sound was full and clear with good balance on console, but I wish it was just a touch louder. Both battle sequences and long cutscenes sounded good on the MH650, and it’s a great way to play when you don’t want to disturb anyone else in the house.

For music I dusted off an old favorite – Pendulum’s remix of the Prodigy’s “Voodoo People.” This track adds some drum and bass to the Prodigy’s classic track, and took me back to a more ancient age where it was featured in the classic film Hackers – ok so maybe I’m dating myself but come on, you can’t be a lifetime tech pro and not have a soft spot in your heart for that movie. All of the levels came through cleanly without distortion or clipping, but again on the whole I wish it was just a touch louder. Granted, that doesn’t mean I didn’t rock out.

Overall

Overall we’re calling the MH670 our favorite out of Cooler Master’s new line of headsets, because we here at TF love flexibility and options in our tech. Being able to use this single unit on every platform we have and adding wireless capabilities to the mix are a big big plus to us. Cooler Master is keeping in with the aggressive pricing of this series of headsets, with the MH670 still not being a bank killer at $119 on the CM Store and Amazon.

TF’s final word? The MH670 is a solid choice for folks who want a one and done audio device for their gaming needs – I’ve used it on my PC, PS4 and mobile devices for gaming and media consumption in headphone mode, and popped the mic in for Zoom and Skype meetings for work. It pulls double duty for work and play.

Pros:

  • Great overall sound
  • Multi-platform compatibility
  • Comes with the cords
  • Excellent value at $119

Cons:

  • Sound could just be a tiny bit louder
  • Can sometimes fit a bit tight for long sessions

The Technical Fowl rating? 9/10

Hi, which one would you recommend between the mh630/50/70 vs the ath g1/wl?

    Tushar April 19, 2020 at 5:20 pm

    Hi Gaelan, great question!

    Based on so far I like the mh670 because of its cross-platform abilities. I actually have Audio Technica’s G1WL on deck so I’ll have an answer for you when I test run it this week!

      Gaelan April 20, 2020 at 1:20 am

      Awesome, looking forward to that. Based just on the 650 and g1 though, how would you compare there sound (if you can remember, if not, I’ll be eagerly awaiting your g1wl review).

        Tushar May 6, 2020 at 4:57 pm

        yo sorry for the delay but the G1WL review is hot and up now: http://blog.tusharnene.com/audiotechnicaathg1wl/

        tremendous sound, i would say above and beyond the MH670, but $249 price point and no 3.5mm. so really that’s your tradeoff
