Whisper guide system allows visitors/audiences to easily hear the tour guide/presenter at a constant volume, without having to worry about how far away they are from each other. This whisper radio is suitable for a variety of situations where communication is difficult due to distance and noise, such as tours, meetings, lectures, training, outdoor classes, church, etc.


— Whisper radio battery runtime

The whisper tour guide system has a battery life of 20 hours. This ensures that the whisper system will last all day long without the need to worry about the unit running out of power in the middle of an event or having to recharge it frequently.

— AUX input and MIC  input simultaneously

The T130S transmitter supports dual inputs. The MIC input allows guides to communicate clearly using the microphone. The AUX input allows the connection of an external audio source, such as an MP3 player, computer, or smartphone, to play pre-recorded audio or music files for tourists or spectators.

— Long-range communication

The whisper system has a range of up to 100 meters. This allows the guide/team leader and the participants to maintain clear, uninterrupted communication even at considerable distances from each other. This is particularly useful in large groups or outdoor excursions where participants may be scattered.


— Easy to use

Transmitter mute function

Simply click the " >" button on the transmitter and the listener will not hear anything. This is useful in situations where the guide needs to communicate privately with others or needs to temporarily pause the audio transmission. Participants will not hear anything during the mute period. Click the + button again to return to normal voice transmission mode.

Auto pairing and channel memory

Whisper radios feature a convenient one-touch automatic synchronized channel. This simplifies the pairing process between transmitter and receiver, eliminating the need to spend time adjusting channels one by one. Once paired, the whisper radio guide system automatically remembers the previously paired channels, meaning there is no need to re-pair each time the device is used.

Turn off all receivers with one click

If you have many receivers, it is very time-consuming to turn them off one by one after the event, you just need to press and hold the transmitter "-" button for about 5 seconds, and all receivers on the same channel as the transmitter will be forced to turn off, improving work efficiency.


— 49 Channel IDs

The T130S whisper radio system offers 49 different channels. This provides the flexibility to operate multiple teams in the same location. Each group can be assigned a different channel, ensuring they can communicate without interference from other groups or external signals.

— Comfortable listening experience

The wireless receiver has volume up and down buttons that allow the audience to adjust the volume to their preferred level. The volume ranges from 0 to 9 levels, ensuring that people of all hearing abilities can find the right volume. In addition, the receiver comes with 3.5mm D-type headphones that fit both left and right ears.

— Flexibility to add receivers

The T130S transmitter supports connecting any number of receivers and working together, allowing guides to add or subtract receivers as group size changes. This means that whether it's a small group or a large crowd, the T130S whisper tour guide system can accommodate all participants.

— Durable 60-slot charging case

This portable charging case can charge 4 transmitters and 60 receivers at the same time, and batch charging makes charging easier and more efficient. You can also use it as a carrying case, which can hold up to 64 whisper radios and all your accessories (headphones, microphone, lanyard) for on-the-go convenience.


— Wireless Microphone

Wireless microphones eliminate the hassle of tangled cords and allow the guide or presenter to walk freely without the constraints of cables. Also, the better sound pickup of a wireless microphone allows the tour guide or audience to focus on what they are hearing without the distraction of background noise. The microphone takes 2-4 hours to fully charge and can work for up to 8 hours.

i would recommend it
With this purchase, I have expanded and improved the quality of my work. The T131S transmitter is great and the groups of 70 tourists were completely satisfied throughout the excursion in Florence.
