Closed type Headphones The close type ear cups feature thick leather padded cushions built from sound dampening foam, designed to offer passive noise reduction from loud surroundings & improve comfort over prolonged use. Powerful Beauty The Steel Series Siberia v 2 headset is the successor to Steel Series Siberia Full-size USB (Universal Serial Bus) headset, which revolutionized several features in the headset industry. The Siberia v 2 features a beautiful design combined with functionality & performance, all in one headset. Retractable Microphone The Siberia v 2 features a retractable microphone that can be hidden in the left earcup, which means you can use it when you need it, but don't have to flash it in public if you don't want to. Quality Driver Units It's one thing to have a beautiful exterior, but it's what's inside that makes these one of the best quality headsets on the market. A 50 mm driver unit with crystal clear sound in high, low, & mid-range ensures quality output for multiple uses. Volume Control The integrated volume controller on the cord offers an option to handle sound volume manually. This feature is especially useful when you are using your Siberia v 2 USB (Universal Serial Bus) with other devices & don't have swift access to setting volume levels in your software. Noise Reduction The earcups feature a noise reducing foam, which helps you to focus on the important audio or voice communication, & not being disturbed or interrupted by outside noise.
