Cooler Master did a great job with their first wireless gaming headset, the MH670. They covered all the bases: The MH670 looks good, sounds great, is comfortable to wear, has an exceptionally durable battery, and at $109/€109, is very reasonably priced, too. There's nothing fundamentally wrong with it, which is obvious if you look at my list of drawbacks, where I'm pretty much nitpicking. Rather than crowding it with aggressive visual elements, which would cater to a younger audience, Cooler Master made the MH670 look very unassuming. It reminds me more of professional studio headphones than something that could be called a gaming peripheral, and I mean that in the best-possible sense. Its flexible frame and soft materials on parts that touch the head (inner headband and ear cushions) result in excellent wearing comfort.

The sound of the Cooler Master MH670 is nice and fun. The bass is deep and pleasant, the highs are fairly smooth, and the mid-range is slightly recessed. All of that translates into a warm timbre. Even though it's not super-revealing in terms of details, it still offers very good performance in movies, music, and games, even those where you need to be completely aware of your surroundings, such as multiplayer shooters.

The MH670 lasted for over 30 hours on a single charge during my testing, which is longer than most other wireless gaming headsets on the market. An average gamer won't have to charge it more than a few times per month. Even if you manage to drain the battery while playing a game, you can still simultaneously charge it and use it, or switch to analogue mode by using the supplied 3.5-mm audio cable. It can even be used in wireless mode with mobile devices equipped with an USB-C port: Cooler Master provides an appropriate adapter.

All in all, the Cooler Master MH670 is a complete package well-worth its asking price. If you're after a good wireless gaming headset but don't want to spend an unreasonable amount of money, there's no need to look any further—this is the one.
