1.Bluetooth 5.1 Technology

EJEAS Referee headset is using Bluetooth 5.1 technology.
The advantage of Bluetooth 5.1 compared with Bluetooth 5.0

    More accurate location
    Less power consumption

As we know, referees need to run with players, and the position of the referee is changing from time to time. With Bluetooth 5.1, EJEAS Referee headsets can pick up the signal anywhere quickly and accurately with very little delay. In fact, it’s already real-time communication considering the distance of the football field is so short. After all, referees can’t move at high speeds as quickly as cars or other transportation tools.

2.CVC Noise cancellation and 3D surround sound

EJEAS Referee headsets have been upgraded several times. The latest version of FBIM now support CVC Noise cancellation and with the latest chip and in-ear headphone, FBIM also supports 3d surround sound.

CVC stands for Clear Voice Capture. CVC noise cancellation is a noise suppression technology developed by QUALCOMM, it can remove background noise from the environment and provide clear voice communication for referees, especially when the referee is officiating a game in a field full of spectators.

3.EJEAS Referee Headset uses AAC Audio Coding Mode

AAC stands for Advance Audio Coding. To better understand AAC, you can take MP3 as a comparison.AAC is an audio coding standard that has been designed as the successor or MP3, AAC has higher sound quality than MP3 with the same bit rate.

4.Long Transmit Distance

Under the ideal setting without any obstacle, the engineer can communicate up to 1500 Meters with 4 units working together. Each headset can speak up to 375 meters. As we know, the length of a football field is 105 meters, the width is 68 meters. Therefore, the distance of EJEAS Referee headset communication is far more than the required communication distance for referees. Referees never need to worry that they are out of service zone with EJEAS FBIM Referee Intercom while they are officiating the game.

5.Hand Free Communication

With EJEAS referee headsets, the referee doesn’t need to push any button after all devices have been connected while officiating the game. It’s totally hand-free communication. When they need to talk to their colleagues, they just talk. And at the same time, they can make calls by flag signals from their hands. This feature is the same as big brands like Vokerro and Yapalong. Unlike talkie walkie intercoms, they need to push the button before they talk to their colleague.

6.Full Duplex Communication

Officiating a football game needs collaboration among the head referee, assistant referees, and fourth official. Sometimes, you need help from VAR. Therefore, the communication must be real-time and get all referees involved. EJEAS FBIM Referee headset is full duplex communication intercoms. Duplex communication means each FBIM headset unit can listen and speak simultaneously to the other 3 FBIM headsets. Just like all referees are gathering as a group to have a face to face communication.

7.In-Ear design earphone

The old version of the EJEAS FBIM Referee Headset comes with ear hang-style earphones. Referees need to hook it to the ear, making it not stable and uncomfortable when officiating the game. Now the latest new upgrade version of EJEAS FBIM Referee Headsets comes with new in-ear design earphones, with a more stable and comfortable wearing experience and more clear and 3D surround voice.

If you are a referee who just started your career, it’s a great option for you to have EJEAS FBIM Referee Bluetooth Intercom. You can compare them by visiting Yapalong and Vokerro official homepage, and checking the price and features of their products.

The disadvantage of EJEAS Referee Headset FBIM

Don’t have push to talk option for the fourth official or VAR(Video Assistant Referee)

The fourth official doesn’t need to be online all the time during the game, they just talk when necessary. For example, when there are substitutions cases or requests the involvement of VAR. Therefore, the push-to-talk option for the fourth official is good for them. Similar to the VAR(Video Assistant Referee), VAR stays outside the pitch, they don’t get involved until not necessary, so the push-to-talk option is also good for them.

Don’t have the charging finish indicator

Charging EJEAS Referee Headset is a confusing thing. You just charge it with approximately time, it’s about 2.5 hours. When you charge it, the indicator is red, and when you finish charging it, the indicator is still red. If there is some indicator showing the charging finish, that will be great. Hope EJEAS will change this in the future.
