GoRef Full-Duplex Bluetooth Referee Intercom Headset Kit — 1 Pack (Football/Soccer)

Built around an optimized Qualcomm Bluetooth 5.1 chip, this GoRef full-duplex referee intercom pairs quickly while maintaining low-energy consumption. It supports real-time communication for up to 4 people and delivers a talking range of up to 1500m (distance of 4 units). Advanced CVC noise reduction cuts echo and background noise for clearer, more stable audio and a 3D sound effect. Power comes from an 850mAh high-capacity rechargeable battery — a 2.5h charge yields up to 260h standby and as much as 19h of talk time, suiting extended referee use during matches.
