This unique support staff set has been specially designed for support staff, trainers, assistants, third referees, fourth officials, etc. This support staff set features a special earpiece with a Push to Talk function, which means that the wearer can only be heard when he or she actively presses this button. The set consists of a standard EJEAS V4. This V4 can connect with other V4s as well as with the classic V6s or combinations thereof.

The earpiece resembles the standard earpiece available elsewhere on the website, but has a unique design in which the microphone has an extra-large Push-to-Talk push button and is still perfectly operable even with ski gloves on. This special companion type earpiece is directly equipped with a USB-C connector and can be connected directly to the V4 unit; thus, an adapter cable is not needed.

The set is also equipped with a standard earpiece (with adapter cable) so that it can also be used as a standard set.
