Advantage of EJEAS FBIM Referee Intercom
1. Full-Duplex Communication
One of the biggest advantages of the FBIM is its full-duplex communication technology.
All referees can speak and listen simultaneously without pressing any buttons, just like having a normal face-to-face conversation.
This is a major advantage over traditional walkie-talkie systems, which require users to press a Push-to-Talk (PTT) button before speaking.
2. Supports Up to 4 Officials
The FBIM system allows up to four users to communicate at the same time:
- Referee
- Assistant Referee 1
- Assistant Referee 2
- Fourth Official
This makes it suitable for most football matches and many other sports requiring team communication.
3. Clear Audio with Noise Reduction
The latest FBIM version features CVC noise reduction technology.
This helps reduce background noise from:
- Spectators
- Wind
- Stadium announcements
- General field noise
As a result, communication remains clear even during intense matches.
4. Stable Wireless Connection
Using Bluetooth 5.1 technology, the FBIM delivers a stable and reliable wireless connection.
During testing on football pitches, communication remained smooth with virtually no noticeable delay, allowing officials to make quick decisions and coordinate effectively.
5. Long Communication Range
Under ideal conditions, the FBIM supports communication distances of up to 1,500 meters.
Since a standard football field is approximately 105 meters long, the system easily covers the entire playing area with a significant safety margin.
Officials can move freely around the pitch without worrying about losing connection.
6. Comfortable In-Ear Headset Design
The latest FBIM uses an upgraded in-ear headset design.
Compared with older ear-hook models, the new earpiece provides:
- Better stability during running
- Improved comfort
- Better noise isolation
- Clearer audio performance
This is especially important during long matches and tournaments.
7. Excellent Battery Life
The FBIM is equipped with a high-capacity rechargeable battery.
Specifications:
- Battery Capacity: 850mAh
- Charging Time: Approximately 2.5 Hours
- Talking Time: Up to 19 Hours
- Standby Time: Up to 260 Hours
- Waterproof Rating: IP65
- Operating Temperature: -10°C to 50°C
A single charge can easily support a full day of officiating.
8. Outstanding Value for Money
Compared with high-end referee communication systems that can cost several thousand dollars, the FBIM offers many of the same core features at a fraction of the price.
Referees benefit from:
- Full-duplex communication
- Noise reduction
- Long battery life
- Reliable wireless performance
without the premium price tag.
For grassroots, amateur, and semi-professional referees, the FBIM is one of the best value referee communication systems currently available.

Disadvantage of EJEAS FBIM Referee Intercom
1. No Dedicated Push-to-Talk Mode
The FBIM is designed primarily for full-time communication among officials.
Some referees may prefer a dedicated Push-to-Talk option for:
- Fourth Officials
- Video Assistant Referees (VAR)
- Match Observers
A selectable PTT mode would provide greater flexibility in certain match situations.
2. Limited Advanced Professional Features
Compared with top-tier systems used in elite professional competitions, the FBIM lacks some advanced features such as:
- Multiple communication groups
- Advanced channel management
- Custom audio routing
- Professional referee network integration
However, these features are generally unnecessary for most grassroots and semi-professional matches.
