Many Xbox Series X and Series S owners have likely pondered the purpose of the small black button situated next to the console's single USB port. While its primary function is indeed for pairing wireless controllers and accessories, this seemingly simple button hides a clever secondary feature.

The Hidden IR Receiver in Your Console

Pairing Controllers and Beyond

Microsoft officially designates this component as the bind button. Its most recognized use is facilitating the connection of wireless controllers and various Bluetooth accessories to the current-generation consoles.

A Sneaky Design Inclusion

What many users overlook is that both the Xbox Series X and Series S house a hidden Infrared (IR) receiver within their chassis. This receiver is not visible as a traditional IR blaster; instead, Microsoft integrated it directly inside the bind button itself.

This design choice was intentional. The team made the button slightly transparent, though subtly enough that most users would never notice the integrated sensor. Microsoft aimed to keep the feature invisible to maintain the console's sleek design aesthetic.

Ensuring Backward Compatibility

Supporting Previous Generation Accessories

The inclusion of this hidden IR sensor was a deliberate move toward supporting existing hardware. Larry Hryb, the former Xbox Live director of programming, confirmed this was part of Microsoft's commitment to bringing previous accessories forward.

This hidden sensor ensures compatibility with official Microsoft accessories from the Xbox One generation that rely on infrared technology. This includes both first-party and third-party media remotes.

However, users hoping to utilize older Xbox 360 controllers and accessories will generally find them incompatible without employing a third-party adapter. Despite this limitation, the Xbox Series X and S continue to be popular consoles that may still hold further useful features.
