Also! If you’re on the latest version of Windows 10, you have access to Windows Sonic for Headphones completely free, and Dolby Atmos is available as well. Don’t forget to look into those!
If you’re buying the Arctis solely for its surround functions, don’t forget to check out these cheaper options first. But if you want it for its wireless capability and its decent mic, then that’s okay. When I first reviewed the 7 the market for wireless headsets was pretty empty, but now there are a million wireless products in the $150 range so it’s not as easy a decision to make! Go with the one that appeals to you most and make sure you buy from a place with a good return policy just in case. :)
