Introduction and Packaging

The CM Storm 5.1 Headset is the first headset, let alone first 5.1 headset to come out of Coolermaster and we have been dying to get hands-on with this true surround sound device. Being their first 5.1retail headset we are intrigued to see how well it performs in comparison to the many 5.1 and 7.1 surround sound headsets we have reviewed. The CM Storm Sirus 5.1 Headset as well as the wheel controller, is comprised of very high-grade materials and looks like a very comfortable headset ready to unleash a great force of audio upon you. Coolermaster are renown in the industry for their cooling products and are really making their name know in the industry for their relatively new CM Storm line. We have reviewed many CM Storm products and all have been of a very high standard and always performance and an attractive and appealing design for the games. Let’s dive into this brilliantly priced headset and check out what it looks like and how it performs, and find out if the CM Storm range had triumphed again...
