The coach can send the messages to the team members clearly inside the water, and they can focus on training. The simple and strong functionality of the transmitter, transmission range inside the water and the durability satisfies the team can coaches. Especially the voice is crystal clear even inside the water.

Retekess TT120 headset is the mandatory equipment for daughter’s swim team. They’ve used other brands before but all have different kind of quality issues, but with Retekess they been have smooth practices all the time. The product quality is very good, durable. Their customer service people are knowledgeable, reliable, and help solving order problems efficiently. Highly recommended!

The TT120 greatly improved our water tourism experience, whether it was yachting, SUP surfing, or underwater activities, the communication was clear and stable, without any interference at all, which greatly enhanced the fun of the activities.

This device perfectly solves the inconveniences in my current swimming training process, such as poor communication. It can also teach multiple groups at the same time. Students do not feel any discomfort when wearing it. I will recommend it to other friends.

We used the TT120 system during sailing competitions and it performed very stably, with clear sound quality and no dropouts during long water activities.

From coaches to students, it is very simple to turn on, pair, and switch channels. The coach can use it after 2 minutes of training, and the students can wear it and turn it on by themselves. There is no need for complicated settings, which saves time and effort.

The tt120 receiver weighs only 39 grams, making it easy to carry and suitable for all kinds of outdoor and water activities. We really liked its lightness and comfort when sailing at sea.

9 channels can support multiple training groups at the same time, and the team training does not interfere with each other, which is especially suitable for swimming training classes.

The most feared thing about listening to instructions underwater is the interference of water sound. This bone conduction transmits sound very clearly, students can hear every technical point clearly, and correct movements more accurately.

The receiver is only 39 grams! After wearing it, you can hardly feel its existence, turning, pushing against the wall, and various swimming styles are completely unaffected. Children will not feel heavy or pressure on their heads when wearing it, and the training experience is greatly improved.

The transmitter operation buttons are large and simple, which can guide underwater students in real time, with better teaching effects and rapid progress of students.

The receiver is waterproof to IP68 and can be used underwater for a long time; the transmitter is waterproof to IP54, so it is completely fine even if it accidentally falls into the water.

We often have several classes at the same time in our swimming pool. In the past, coaches would talk to each other. TT120 has 9 channels. We have multiple groups taking classes together, each teaching their own, and the channels are independent and clear without interfering with each other.

The receiver is IP68 waterproof, so there is no need to worry about water ingress at all. Even training in deep water is stress-free and it is very safe to use.

The transmitter has clear buttons and IP54 waterproof and splash-proof. It is very convenient for coaches to guide by the water without frequently debugging the equipment.

In the past, training relied entirely on shouting, and students couldn't hear clearly when their voices were hoarse. Now with this interpreter, students' underwater instructions are directly transmitted to their ears (bone conduction), the sound is clear and does not affect others, the coach is relieved, the students are more focused, and the teaching efficiency is doubled.

The bone conduction receiver is only 39g, and you can hardly feel the weight when wearing it on your head. You won't feel tired even if you swim for a long time. The design is really user-friendly.

As a competitive swim coach, I've tried every communication device out there. The TT120's bone conduction delivers crisp instructions even during flip turns. The 9-channel system lets me run separate drills for sprinters and distance swimmers simultaneously. Game-changer for my elite squad.

I recommend it to all my students, which effectively improves the teaching quality. I walk around the pool with the transmitter, and give instructions whenever I see a problem. Students can hear and adjust their movements in the water immediately.

I tried it out at first, but now I completely rely on it for my swimming lessons. The bone conduction earphones make communication easy, and I can give instructions no matter how intense the training is. It is also waterproof and has no problem at all. Highly recommended for all water sports enthusiasts!

As a swimming coach, I have significantly improved my training results after using this wireless communication system. The instructions are clearly communicated, even underwater. My students have given it great feedback, especially when they are training in a team, and they can better understand the movements. Most importantly, it is comfortable so I don't feel any discomfort during long-term use. I will report back here if anything happens, but so far, this actually works.
