Cooler Master has just announced its latest addition to the CM Storm line of gaming accessories. The Sirus S 5.1-channel gaming headset is a variant of the Sirus which ships with a custom 5.1-channel USB sound card.

The original Sirus dates back to spring 2011 and included a purpose built USB sound card, effectively making the unit more expensive. Cooler Master designed the Sirus S to run without the sound card and includes a simple volume control pod and 3.5mm audio jacks.

This new setup allows users to take advantage of their own sound card or even the motherboards built in HD integrated audio. We expect that Cooler Master decided that the constant driver support needed for a custom sound card was just too much and redesigned the headset as a quiet way out. The Sirus S should be much cheaper than its predecessor when released in February.
