My football crew and I finally decided to take the plunge and get these. After a few weeks I have to say I love having these for our on field communication. It helps us immensely and is very easy to use.
I use this when I am umpiring field hockey. The only issue I have, is the ear piece that is pictured in the ad, is not the one that came with the unit. All other conveniences perform well: it can be quickly paired, 4 people can talk to each other simultaneously, and the sound quality is clear.
This is the best referee headset I've ever used. Four of us referees can communicate simultaneously, and the sound quality is crystal clear. The most remarkable thing is that the price is several times cheaper compared to other brands I've bought before.
My name is Demetri Anastasiou and I'm a Level 5 football referee in UK. I bought a set of FBIM (pack of 4), and they also gave me a suitcase, which was an unexpected surprise.
Pairing is relatively simple, and 4 units can be connected together quickly. Of course, I did it while watching their videos on YOUTUBE.
In the game the day before yesterday, I tested FBIM, and the effect was satisfactory. First of all, I could speak clearly to another referee at a distance of about 900 meters. The manual said it could reach up to 1500 meters; secondly, the battery, I used it for more than 100 minutes after it was fully charged. For 3 football games, the battery is still sufficient, because it uses a lithium battery with a capacity of 850mAh, and the intercom time can be up to 19 hours; it comes with in-ear professional referee headphones, so you don’t have to worry about the headphones falling off during running.
The rest of the functions have yet to be tested, such as waterproof function, noise prevention, etc. Overall, I am very satisfied with FBIM. This is what I want to say, thank you.
