The story behind the CH321…

Let’s face it, RGB is in and a lot of people look out for RGB in almost everything from keyboards to mice to headsets. The only thing stopping most people from buying everything RGB is usually the price. Cooler Master probably figured out a gap in the market for an affordable RGB headset and thus the CH321 was made. So the Cooler Master CH321 seeks to address the lack of low-end RGB headsets in the market. Regardless, its primary purpose of headphones and headsets should be good- sound.

The Cooler Master CH321 is a USB headset which means it has a built-in DAC and hence it overrides your laptop or PC sound card. The upside is the same sound quality irrespective of which system it is plugged in. The downside is that you can’t connect USB headsets via 3.5mm headphone jack such as your phone or your TV. Even front panel connectors on the motherboard and case have single 3.5mm pin support for the headphone and the built-in mic. BUT… the USB powered headsets enables RGB. Cooler Master has made RGB more accessible to people. So if you love all things RGB and don’t wish to spend too much on an RBG headset this Cooler Master CH321 could be just what you are looking for!

The CH321 has a basic package. The headset comes in a standard dark grey box with a splash of purple like almost every other Cooler Master headset box these days. Inside you get the headset and nothing else. Considering the low price point of this RGB headset that is not a deal-breaker. The Cooler Master CH321 has a very decent build quality and looks well built with a nice thick cable. The headset has a slightly strong clamping force which does cause me some discomfort over a few hours but it is not severe and YMMV.

What’s there in the CH321?

There are no physical buttons anywhere other than the volume control on the headset itself which is very useful. The downsides are that the microphone isn’t removable though it is very compact and not a bother. There is no mic mute button on the headset. The cable is also non-user-replaceable but it looks well built and since it very thinks it doesn’t tangle easily. There are no drivers or software to control the RGB lighting and hence no customization options.

Headphone cups

The headphone cups are medium in size. The headset sits on your ears which consequently can cause you some discomfort over time. The cups are non-adjustable and so so you can’t swivel them around or fold them for portability. Finally, you have the consider the price point of these RGB headsets and (in my opinion) the headset is well built and there is little to complain about the packaging.

Cooler Master MH630 Headset Review

The Cooler Master MH630 is a headphone without a DAC. Consequently, it doesn't have any fancy RGB lighting and effects. If you love to have RGB bling on a headset, this isn't for you. But the MH630 has everything else you could ask for- a detachable cable, built-in volume control and a detachable microphone. Since the Cooler Master MH630 has a 3.5mm jack it works great on almost anything you can connect it to. Moreover, there is also a splitter to enable you to connect it to a source that has a separate mic input.

Cooler Master MM710 Gaming Mouse Review

Cooler Master has a good share of mechanical keyboards since its CM Storm days. But its venture towards gaming mouse has an erratic hit or a miss. I did like the CM Storm Alcor and the shell of the CM Storm Mizar but that was about it. Cooler Master really needed something that can have the best of both worlds. But CM Storm Alcor was light, a pro in itself wasn't really pushed ahead.
