Vulcan PRO effectively offers a souped-up version of Vulcan ANC. It uses the same gaming-optimized active noise cancellation technology, which blocks up to 85% of noise distraction. This high degree of isolation helps us immerse in the game better, obviously, hence the tagline Focus to Win. The tight but comfy ear cups/cushions employ memory foam and premium protein leather to ensure a good fit on gamers' heads, resulting in about 30dB of passive noise resistance. So whether you choose to engage the battery-powered active cancellation or not, Vulcan PRO feels very quiet. Trust, me I've tried it in different locations, and it works!
