I would like to leave a review for the Retekess T130U audio guide. I liked that the device is very lightweight, easy to use, and comfortable to handle. From my initial experience, the battery holds up well. Since we haven’t had any long tours yet, I can’t accurately assess the battery life during extended use. Once we have longer excursions, I will be able to provide a more precise evaluation of the battery performance.

We’re very satisfied with the product and have used it several times now. Each time, it’s been extremely well received by our guests, which is always great to hear. The functionality is particularly appreciated. The devices are intuitive and easy to use, and the single-button power-off feature is especially helpful, as it allows us to ensure everything is properly switched off at the end of each day, giving both our team and guests peace of mind. We’ve also noticed a significant improvement in transmission distance compared to the first-generation equipment, which has made a real difference to the overall guest experience while on tour. Unfortunately, we don’t currently have any photos taken during tours, but if we’re able to capture some in the future, we’d be more than happy to share them with you.

At the same time, separate channels were used to guide hundreds of new students through different colleges. UHF digital transmission eliminated crosstalk, and the explanations from humanities and engineering departments did not interfere with each other, resulting in a well-organized process.

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.
Anthony Nguyen

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.
Sadie Vivenzio

The system’s Bluetooth and AUX compatibility is a game-changer. We were able to connect our own devices and microphones seamlessly, which gave us more flexibility in how we run our tours.

Recommendable, efficient charging, easy to operate and long life. However, would like to add some extra accessories

Performance in use is quite good, the device is stable and there is almost no noise interference

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.
