VOKKERO was the first wireless communication system designed specifically for professional soccer referees — lightweight, compact, and equipped with a patented noise filter built for the pitch. Since 2005, VOKKERO has been trusted by FIFA, UEFA, CONCACAF, and MLS, and was the official system at the 2010 and 2014 FIFA World Cups. In the United States, VOKKERO is widely used by MLS officials and Division I college referees, delivering real-time, hands-free communication at the highest levels of play. Today, the VOKKERO Elite and VARSITY II systems bring the latest advancements in wireless officiating technology — offering professional-grade performance for top-tier programs and budget-conscious organizations alike.
