Sales of Valve’s Index Headset Are Waning After Years of Surprising Longevity
Valve's Index VR headset has been on the market for over four years and continues to sell well, despite newer and cheaper options being available. It remains the second most-used headset on Steam, making Valve the second largest headset vendor on the platform. However, sales of the Index have started to decline, possibly due to Valve shifting its focus to promoting its Steam Deck device. The exact reason for the decline is unclear, but it may be related to the increased promotion of the Steam Deck on the Steam storefront. For more information, please visit the source at Road to VR.
