This wireless group listening device helps visitors and audiences hear the guide or presenter clearly at a consistent volume, even in noisy or wide-area environments. The T130S whisper radio system is a practical solution for tours, meetings, schools, lectures, training sessions, outdoor classes, church events, and other group communication scenarios.
Phase-locked loop (PLL) technology helps reduce interference and delivers clear, stable audio.
Automatically sync transmitters and receivers with one click, or manually set channels when needed.
The rear belt clip keeps the transmitter secure and easy to carry during tours and presentations.
Supports multiple groups in the same area by using different channels to avoid cross-group interference.
Dual Audio Input - Use the microphone and external audio source, such as an MP3 player or phone, at the same time.
100m Clear Range - Stable communication for larger groups, indoor venues, and outdoor tours.
Mute Function - Press the transmitter's ">" button to pause audio transmission to all receivers.
Group Power Off - Long-press the transmitter’s “-” button for 5 seconds to turn off all receivers at once.
Volume Control - 10 volume levels on the receiver, with D-shaped earpieces for both left and right ears.
Scalable System - Add unlimited receivers to fit different group sizes.
You can charge the devices with the USB cable included in the kit, or choose bulk charging options for easier storage and management.
