Razer Surround is free to use—for now. Razer is making the software available for download at no charge through the end of the year, though the company encourages users who like the software to donate money to the Child's Play charity. Next year (starting on January 1, 2014), new users must pay $20 to sign up for Razer Surround. Razer Surround works with every version of Windows from XP onward; so if you've been living in stereo, grab it now to get a taste of what you've been missing.
