TT116 plant tour headsets are a wireless communication tool designed for scenarios such as manufacturing plant tours, plant tours, factory visits, church worship, and internal company use.
- Noise-canceling technology
Industrial tour headsets use advanced noise reduction technology to effectively filter out background noise, ensuring that participants hear only the audio they need and eliminating distractions from the surrounding environment. This feature enhances the overall communication experience during the factory tour, allowing participants to focus entirely on the information provided.
- Replaceable batteries
For convenience and uninterrupted use, the tour guide system for factories is equipped with rechargeable batteries that can be easily replaced. This means that even if the battery runs out during the tour, it can be quickly replaced so that it can continue to be used without interruption.

- Avoid the hassle of airport security restrictions
Retekess TT116 plant tour headsets feature a removable battery, so you can confidently board the plane without worrying about the limitations of a built-in battery. Simply remove the battery before boarding and you'll breeze through security with ease. Compatible BL-5C batteries are common, and you can buy them locally after disembarking the plane.
- UHF frequency
The TT116 tour guide system for church is designed with the UHF band, which is highly resistant to interference and ensures reliable, interference-free signal transmission. This allows for clear sound quality and strong wall penetration, enabling visitors to clearly hear the demonstrator's instructions or explanations even in crowded and noisy environments.
- Location for advertising stickers
To enhance branding opportunities and display important messages, the Retekess TT116 tour guide system has a dedicated spot for advertising stickers. This allows the company to display its logo, slogan, or any other relevant information, creating a strong publicity effect during external reception and communication, so the Retekess TT116 is extremely suitable for internal company use.
- Portable 30-slot charging case
The charging case is made of aluminum alloy, durable, and fireproof. It can charge up to 30 TT116 tour guide transmitters and receivers at the same time, avoiding tangled wires and making charging safer and more convenient. In addition, the charging case has a "PAIR" button and supports one-click pairing of the transmitter and receiver.
- Working range
The TT116 tour guide system has a working range of 200 m, allowing visitors to move freely within the range during a factory tour or church event while maintaining uninterrupted contact with the tour guide.

- Running time of headsets for factories
The transmitter can operate for 10 hours on a single charge and the receiver can operate for up to 13 hours. This ensures that factory tour guides and visitors can use the plant tour headsets throughout the day without the need for frequent recharging.
- Automatic locking
If there is no operation within 30 seconds, the buttons will automatically lock and the "🔒" icon will be displayed on the screen. The auto-locking feature of the TT116 factory tour guide system prevents accidental touches and avoids misoperation by users, ensuring that the selected settings remain unchanged throughout the plant tour.
- One-touch mute transmitter
In addition, the transmitter supports a one-touch mute function, providing a quick and easy way for the presenter to temporarily disable audio transmission. A short press of the transmitter's power button suspends sound transmission, at which point visitors wearing the headset will not hear anything from the transmitter.
- Automatically sync channels
Plant tour communication systems also support one-touch quick pairing, making it easy and efficient to connect the transmitter to the receiver and saving time during the setup process. In addition, the devices have a channel memory function so that the channels do not change when they are paired and turned on again, eliminating the need to pair them every time they are used.
- Turn off all receivers with one click
TT116 tour headsets for factory tours make it easy to manage receivers on the same channel. Simply press and hold the transmitter "S" button for 4 seconds to switch off all receivers on the same channel as the transmitter at the same time, simplifying the cleanup process after a factory visit.

- 50 channel IDs
With 50 available channel IDs, the tour guide system for church can accommodate multiple tours or groups in the same place without interference between the 50 groups. This ensures that each group has its own dedicated channel, preventing any confusion or overlap of audio signals.
- Simultaneous use of microphone and AUX inputs
The TT116 transmitter can use microphone input and AUX input at the same time, giving the guide the flexibility to incorporate other audio sources, such as pre-recorded content, into the factory tour. This enhances the overall tour experience.
