New communications system to be launched in two phases from Saturday
NBA referees will wear headsets during regular season games for the first time in league history. The change, which began on Saturday, is part of a two-phase rollout aimed at improving communication and efficiency during hosting.
Phase 1: Limited use during review period
The NBA announced Friday that referees will begin using headphones that clip onto their uniforms. During this initial phase, the device is only activated during instant replay review and other match interruptions, rather than while the game is in progress.
The first phase is expected to last until January. Officials will use the technology to streamline replay decisions and improve coordination with the NBA’s replay center. The league hopes the increased communication will make rulings faster and more consistent.
Phase Two: Full-time Communication
Pending successful initial testing, a second phase will expand the use of the headset to live matches. Referees will be able to communicate directly with each other and the replay center throughout the game. That phase will last at least until the All-Star break in February to allow the NBA to gather data and feedback before deciding to make it permanent.
The league emphasized that this change is intended to enhance real-time collaboration among officials, reduce confusion, and create a smoother viewing experience for fans.
Tested at multiple NBA events
While this marks the headset’s regular-season debut, the NBA has been testing the system at multiple events since 2022. Trials took place during the G League Winter Showcase, NBA Summer League and preseason games.
Leagues around the world have been using similar communication tools for years, especially in football and rugby, where real-time conversations between referees help improve accuracy and consistency. The NBA’s initiative reflects these standards as part of its ongoing efforts to modernize officiating.
The introduction of headset communications represents another step in the Alliance’s growing investment in technology. Implementing from Saturday, fans will see referees equipped with new tools designed to improve the flow and fairness of the game.
