Listen Technologies' fast and simple two-way wireless encrypted group communication. Wireless and secure collaboration among two or more people in any environment.
Designed to be the new standard for two-way mobile communications, the ListenTALK Transceiver is the smartest system available. The all-in-one device, equipped with Listen Technologies' exclusive encryption technology and push-to-talk functionality, provides the simplest option for communication and collaboration among two or more people in any environment.
Each transceiver can function as a leader or participant. Simply turn the units on and designate one to be the leader by attaching the included leader clip. Up to two leaders can be designated per group.
A group is created by using the near field communication (NFC) by pairing the leader unit to the participant units, by touching them back to back. Pairing can be done with the push of a button when using the optional docking station.
In addition to the included Listen Ear Speaker, ListenTALK can be used with standard smartphone earbuds or a Listen Technologies headset.
