There are two types of ear pads that come with the Sirus; foam and padded. The foam pads were shipped pre-installed but can be easily removed and swapped for the padded ones. Generally foam pads are considered more breathable and should generate less heat / sweat when used for a long period of time, but are less "sound-proof" than padded pads. This really comes down to personal preference but it's nice that Cooler Master included both for the end user to choose from.
With the padding removed we can see each of the four speaker locations; three 30mm drivers and a 40mm subwoofer driver.
The braided cable for the headset is permanently connected to the left ear cup and terminates into a male 10-pin Mini-DIN connector. This connector can either be plugged into the desktop control module or into the analog bypass which feeds directly to your sound card.
The control module looks really nice and has enough weight that it won't be sliding around on your desk as you reach to make adjustments. Adjustments here include Rear, Front, Master, Center and Bass. You can select each mode by pressing the unmarked button below the adjustment dial. The button on the left turns the headphones on / off while the right button does the same for the microphone.
If you haven't noticed yet, all of the connectors on the Storm Sirus are gold plated. Additionally all of the cables (except the analog audio adapter) are covered in black mesh.
Just to clarify, if you are using the desktop control module, you will need two free USB ports on your computer. If you are using the analog connections to tie in directly with your sound card, you will only need one free USB port.
