Great portable system!
After 1 month of use, we are vey satisfied with the TT122 system. When purchasing a tour guide system you have to be aware of the wavelengh operation range. This kit work on 2,4Ghz and use the "newer usb-c" plug for charging. We are mainly using it in a static set-up. Lecture room. Emitter are installed at the back of the room and are high enough from the floor to avoid interference. In a static system, the postion of the emitter is critical. If you place it too low and the signal have to go through many human body before reaching the receiver, the signal may be attenuated. In our case, the signal can even go throught 1 or 2 wall with a clear reception. Don't forget that this system is designed for mono earhook headphone supply with the kit. For our set-up we use on-ear stereo headphone that cover both ear. It work aslo well but I noticed when using stereo headphone that the white noise is attenuated when the 3,5mm jack is not fully inserted. So I have designed small PVC ring spacer for our 3,5mm jack heaphone that give the right insertion to get the best signal/noise ratio. Voilà! The portable charging case is also very handy. We can set-up a translation very quickly with ease! Great value! At these price you cannot go wrong! This system cost 10x less then the Sennheiser TG 2020 and deliver really good performance! Overall very positive experience, peoples were impressed by the sound quality! Costumer support is very responsive, top tier communication! +++
Seamless language translation
I bought the TT122 translation system for our school auditorium last month and I couldn't be happier with its performance. As an educator, I wanted to make sure that our students could experience our school events without language barriers, having a reliable translation system is crucial. The interpretation equipment allowed us to translate live speeches into multiple languages, only a few interpreters are needed. My colleagues and I were impressed with its audio quality and user-friendly.
TT122 Interpretation system exceeded my expectations
I was blown away by the Retekess TT122 Translation System at my church! Not only was it easy to use, but the sound quality was pristine. The congregation could clearly understand every word spoken by the pastor, and I was so grateful for the opportunity to worship without any language barriers
