Long battery life for uninterrupted use:

With a 20-hour battery life for the transmitter and 120-hour battery life for the receiver after just 5 hours of charging; TT129 tour guide system wireless ensures uninterrupted use throughout long visit days.

Large range:

100m between main and secondary transmitters and 200m between transmitter and receiver in open spaces; TT129 tour guide system wireless ensures clear communication even in expansive environments.

Customize noise reduction to your environment:

With 4 levels of intelligent noise reduction.  You can adjust the settings to suit your specific environment whether you're in a noisy training facility, a bustling academic conference. Easily adjust the intelligent noise reduction level with a simple long press of the ANC button on the transmitter, allowing you to adapt to changing environmental conditions throughout the day.

Note:

The interface between the microphone and the earphone is tight and needs to be plugged in to the bottom, otherwise the audio quality will be poor or the signal will not be connected.

Use scenarios:

1. Tour guides: three guides working together
The three-transmitter function of TT129 is particularly important in the case of large tour groups or multilingual tourists. Each guide is equipped with a transmitter (M, S, R) and can explain different topics or languages ​​separately, ensuring that all tourists can hear the explanation clearly.

Examples:

Historical site explanation: one guide explains the historical background, another guide explains the architectural details, and the third guide answers tourists' questions.

Multilingual explanation: For tourists with different languages, three guides use different languages ​​to explain, ensuring that information is conveyed without obstacles.

TT129's 999 channel selection and 4-level intelligent noise reduction function ensure a clear audio experience even in noisy environments.

2. Factory tour: multiple receptionists guide
In factory tours, multiple receptionists are usually required to explain different production areas or process flows separately. The three-transmitter mode of TT129 enables each receptionist to speak independently, ensuring that the information is conveyed clearly and without duplication.

Examples:

Production process explanation: One receptionist explains the operation of the production line, another receptionist explains the quality control process, and the third receptionist introduces safe operating regulations.

TT129's 120-hour receiver life is suitable for long factory visits.

3. Meetings and training: multiple hosts or lecturers
In meetings or training that require multiple lecturers or hosts to discuss together, the three-transmitter function of TT129 allows each lecturer to speak at the same time to avoid delays or duplications in information transmission.

Examples:

Expert panel discussion: Three experts give their opinions on different aspects of a topic, and participants hear the views of the three experts at the same time through the receiver.

Multi-lecturer training: Three lecturers are responsible for different modules of training content and interact with trainees.

TT129's simple operation interface and intuitive display design allow lecturers to easily switch channels, adjust volume or enable mute functions during meetings or training to improve communication efficiency.

Last week, I used tt129 with a group of 40 people. Three tour guides each took a transmitter. The three of us could talk to each other at any time to coordinate the route, remind safety, and relay the explanations to switch seamlessly. The efficiency was super high! The receiver was still fully charged after a day.

The distance of the equipment is the most challenging when leading a hiking group. After purchasing, it was tested and performed very reliably in the woods and open areas. The three team leaders (one in the front, middle and back) used the transmitter to communicate the team status and road conditions at any time, and they could also broadcast important information to the whole team at the same time (such as changes in the assembly point), which greatly improved the flexibility and safety of leading the team.

When organizing a three-day and two-night outdoor training, I was most afraid that the equipment would run out of power during the trip. The battery life of the tt129 receiver was amazing, which gave me a great sense of security. I didn't charge it once during the whole trip, and it still had power after the activity.

In the past, communication was always poor in team activities or large meetings. The 3-transmitter group function of tt129 is great! The three of us can communicate and discuss freely at any time, and all information can be conveyed to all members wearing receivers in real time. The 120-hour standby time of the receiver means that there is no need to worry about charging for multi-day activities, and the efficiency of team collaboration has increased sharply!

As lecturers who often organize large-scale training, tt129 solves our big pain point! My two assistants and I each hold a transmitter. I can give the main lecture, and the assistants can supplement, ask questions or answer students' questions at any time. The three of us can also communicate quietly to adjust the process without disturbing the students at all. The audience can hear clearly wearing the receiver. Throughout the training, the equipment was online throughout the whole process, and the effect was very professional and smooth.
