T130U T131U digital group tour systems offer key advantages such as anti-interference and noise reduction. They optimize sound quality through digital modulation, while the encoding method minimizes harshness and reverberation caused by interference, enhancing transmission security. Whether in crowded tourist attractions or complex environments, tourists can clearly hear the guide's explanations without disruption from surrounding noise.

The tour guide's voice is presented to the audience clearly and vividly, minimizing distortion and external noise.

In addition to supporting MIC input, it can also transmit external audio via Bluetooth or AUX interface.

The T130U audio guide system has a long working distance, up to 200m/656ft ft in an open area.


Equipped with a built-in rechargeable lithium battery, the receiver can operate continuously for up to 40 hours, while the transmitter functions for 10 hours, without frequent recharging. Whether it's a full-day excursion or a multi-day tour, the stable power supply ensures uninterrupted guiding.

Simply press the mute button on the transmitter to mute the receiver, making it convenient for private conversations.

The one-click automatic channel synchronization eliminates individual pairing; the system remembers previously paired channels for easy use.

The one-click shutdown function saves time by forcing all receivers to turn off simultaneously.


The T130U digital group tour system supports dual charging options: Type-C cable and contact-based charging with 32/60-slot case for efficient multi-device powering.

The transmitting microphone offers 4 levels of gain adjustment, and the receiving volume offers 10 levels of adjustment.

The T131U receiver will automatically turn off if it does not receive a signal for 20 minutes.

Supports connecting any number of receivers and working together.


The chest-hook style is compact and portable, featuring a universal ear hook for both ears for flexibility and comfort, and replaceable foam covers ensure hygiene.
The transmitter supports charging while in use, allowing for normal operation even with low battery.
It supports up to 50 channels, ensuring that audio transmission will not be interfered with even if multiple teams are working at the same time in the same area.

The receiver's 40-hour battery life is incredibly practical! I basically don't need to charge it for a week, completely eliminating 'battery anxiety' and allowing me to focus all my energy on the presentation.

When leading student tours, the children are naturally active and often run far. With the T130U, the 200-meter working distance gives me much peace of mind. I don't need to shout myself hoarse to ensure every child can hear my explanation, protecting my voice.

We used this system for a large group tour, and the communication range of up to 200 meters was fantastic! Everyone could hear clearly, even when spread out over a large area.

The T130U system delivers crystal-clear, digital sound with minimal interference. I’ve used other tour guide systems before, but none compare to the noise cancellation and digital audio quality of this one.

I bought these tour guide systems for my travel agency and they have been a huge hit with our clients. For our large tour group, these were perfect. Crystal clear audio, even in the loud environment. Our guests loved the clarity and ease of use, and we received so many compliments.
