I recently purchased a 4 pack communication system and purchased 2 packs as backup. I have been impressed with its performance. The sound quality is excellent, and the system is easy to set up and use. The noise-cancelling technology works exceptionally well, and it filters out background noise, allowing clear communication among the referees during matches.I also love the long battery life of the V4 Plus system. It lasts for an entire day of matches, which is very convenient. I highly recommend this communication system to any referees looking for an affordable and reliable solution for their communication needs.Overall, the V4Plus referee communication system is an outstanding product that has exceeded my expectations. It has made my job as a referee much easier and more efficient. It's a solid product for those who are looking for an affordable communication solution for their referee needs.
