EJEAS V4C Plus 4-Person Referee Intercom Kit — Qualcomm Bluetooth 5.1, 1500m Range, 750mAh

Designed for match officials and event teams, the EJEAS V4C Plus is a compact 4-piece intercom system built around an optimized Qualcomm Bluetooth 5.1 chip for fast pairing and low-energy operation. It supports simultaneous conversation for 2 to 4 people, with an intercom distance that can reach 1500m (distance of 4 units). Voice clarity is improved by advanced CVC noise reduction technology that suppresses echo and background noise, delivering stable, intelligible audio in noisy environments. The unit uses an in-ear headphone design for a secure fit during rapid movement, and the small, lightweight body can be slipped into an armband without affecting performance. Power is handled by a high-capacity 750mAh rechargeable battery. After a 3h charge the set provides up to 18h of intercom talk time, up to 24h of music playback, and about 260h of standby — ample runtime for lengthy matches and events. The V4C Plus is aimed at referees in football, basketball, golf and similar sports, and it also works well for training sessions, construction site coordination, venue scheduling and other outdoor activities where reliable team communication is required.
