Comfort
Cooler Master addresses comfort with three main areas of padding: the left and right ear cups and a piece to rest on the top of the head. The choice of ear cups was mentioned before, which is a nice option that allows users to decide which is more important to them: noise cancel or comfort. Each ear cup has about an inch or so thickness of padding, which even after a few hours of gaming was enough to keep my ears from being irritated.
The ear cups are more of a trapezoid shape, the width along the top of the piece longer than that on the bottom. Compared to the common egg-shaped cup, this form tends to better suit a larger array of ear sizes, as the egg often cuts into the cartilage for larger ears. The design also helps to house the directional surround sound speakers.
I'm notorious for breaking little clips, and with an expensive pair such as the Sirus, I was definitely nervous to try exchanging them for the first time. To my relief, the cups are engineered to be friendly to use and survive several detachments.
Along the top is a piece of padding around six inches in length, which is fairly thick and does an excellent job keeping pressure off the head. Both sides of the Sirus also extends to guarantee the set will fit regardless of head size.
I was also initially a little concerned about the weight of the headset, simply because it looks heavy. As opposed to similar competitive models that use thinner lines of plastic and fabric, the entirety of the Sirus is a plastic mold. Combined with the cushioning of the headset however, the only reason I knew the set was on was the amazing quality of sound, even in extended sessions.
