TT126 two-way communications headsets allow team members to stay connected and communicate effectively during factory tours, tours, meetings, training, and various other activities.

Clear digital audio quality
Digital signal transmission, strong anti-interference ability, and better signal quality.

Long battery life
Built-in 2500 mAh lithium battery; transmitter provides 10 hours of use on a full charge; receiver provides 10-70 hours of continuous operation on a full charge.

Factory Tours and Training
A safe and efficient tour experience. Visitors can clearly understand the equipment and processes, and questions can be answered in real time, ensuring seamless communication. It is recommended to choose noise-canceling headphones in noisy environments.

Interactive Training/Teaching
Students can ask questions, share ideas, and enhance interaction at any time. Instructors can flexibly control one-way and two-way modes, making it easy to control the situation.

Tour Guide Experience
Immersive tour experience. Guides interact with visitors via the TT126 audio communication system, allowing them to ask questions and gain deeper insights.

Equestrian Training
Efficient instruction, seamless interaction. Coaches can clearly convey every step of a demonstration and provide timely corrections to riders. Riders can also ask questions at any time, enhancing learning outcomes.

Sports Commentary
Enjoy the excitement of the event. Commentators interact with audiences in real time, answering questions and connecting with them.


You can wear it around your neck or clip it to your clothes with a back clip according to your needs.

The operation is simple and intuitive, helping users get started quickly and use the system more efficiently.

The transmitter supports audio input and can connect to another audio device, such as a smartphone or MP3 player, to communicate with the group.

Our standard headphones support both left-ear and right-ear wear.

The dual-color display is clear and can show all operations.

Two charging methods: Type-C charging and contact charging. For bulk charging, the charging case is preferred because it is convenient and efficient.
The 2-way tour guide system allows the user to adjust the microphone sensitivity according to the venue size, background noise level, or personal preference. By adjusting the sensitivity, users can ensure that the system picks up their voices clearly and transmits them efficiently to all participants.
The main transmitter can speak when it is turned on, without pressing any buttons. However, when the vice transmitter needs to speak, there are two call modes (P mode and S mode) to choose from. In P mode, the user needs to long-press the call button to talk, which is suitable for quick communication or conversation. In S mode, the user only needs to press the talk button once to talk, which is convenient for transmitting longer messages.
Main transmitter and vice transmitters can communicate clearly and stably over a range of up to 280 m. This is especially useful in situations where team members are dispersed or working over a large area, and participants can move around freely without fear of losing connection.
The key lock feature helps prevent accidental button presses or setting changes during a meeting or training session. This ensures stable and smooth communication, allowing users to focus on the discussion or training content without interruption from accidental button presses.
The full-duplex two-way radio has 25/12 available channels (the European version has 12 channels; the US version has 25 channels). This means that different groups within a team can have their own dedicated channel, with no signal interference or audio overlap between groups.
If the vice transmitter does not receive an audio signal for 20 consecutive minutes, it automatically shuts down. This helps conserve battery life and ensures that the vice transmitter does not run out of power unnecessarily when not in use.
