A large manufacturing enterprise once organized offline training for 500 distributors across the country. However, the wireless tour guide devices used at the scene completely broke down – the machines in the workshop were making loud noises. The instructors’ instructions could still be heard clearly by the front-row participants, but those in the back rows could only watch the PPT and guess the content. During group discussions, it was even more chaotic. The explanations from different groups interfered with each other. The instructors had to repeat their explanations several times, but the participants still only had a partial understanding. The efficiency of the entire training session was so low that it was causing great concern. In fact, when choosing a tour guide device for training scenarios, it’s not enough to just pick any one. Selecting the right brand and model is essential to doubling the training effect.
I. In the training scenario, the most troublesome issues with wireless tour guide devices are as follows
1.Sound interference: Key information fails to be transmitted properly
The training environment is inherently complex, with the noise from machines in the workshop, the noise from people in the meeting room, and the wind noise during outdoor training. Even a slightly faulty tour guide device will have its sound mixed together, making it impossible to hear anything clearly. Especially in technical training, where parameter explanations and operational details are crucial, if the sound becomes unclear due to background noise, the trainees may misunderstand, and subsequent operations are prone to go wrong. The training becomes useless in such cases.
2.Unstable connection: Multiple users often experience disconnections
Large-scale training sessions involve anywhere from dozens to hundreds of participants, and the trainees may be scattered in different areas. Some tour guide devices have poor signal coverage, and the connection may drop or become laggy while walking. What’s more troublesome is when multiple teams are conducting parallel training sessions. The channels interfere with each other, and one team is explaining product knowledge while another team’s sales training content is carried over. Both sessions are affected, and it’s impossible to carry out the training synchronously.
3.Insufficient battery life: Interruption due to power failure disrupts the rhythm
All-day training requires a considerable battery life. Some tour guide devices can last for 8 hours, but in practice, they run out of power after 4 or 5 hours. Stopping the training to let the trainees charge not only disrupts the training process but also distracts the trainees’ attention. It becomes difficult to refocus later.
4.Complex operation: It’s too cumbersome to organize
Before the training, equipment needs to be quickly distributed. If the tour guide devices are difficult to pair or have many buttons, temporary helpers may take half a day to learn how to operate them. Just debugging the equipment alone takes more than half an hour, seriously delaying the start of the training and causing anxiety for the organizing party.
II.The Yingmi E8 Tailored to Training Needs
After 18 years of deep involvement in the interpreter industry, Yingmi has always understood the training scenarios’ requirements when developing products. Its E8 team tour guide system is specifically designed to address these issues. Many enterprises and training institutions have adopted it and have given positive feedback.
1.Patent noise reduction + high-definition sound quality, even in noisy environments, you can hear clearly
The Yingmi E8 features a patented SOC embedded integrated digital noise reduction technology, which is extremely crucial. Whether it’s the loud noise of machinery in the workshop or the crowded and noisy large conference room, it can filter out the background noise and ensure that the speaker’s voice can be clearly transmitted to each trainee’s ears without missing any key information. Moreover, it supports two usage modes, allowing both real-time lecturing by the instructor and the pre-saving of training course materials for loop playback. It can be used for both theoretical and practical training sessions.
2.Stable connection + multi-channel design, no chaos in multi-person training
It uses a carrier frequency of 860MHz-870MHz, with particularly stable signal transmission. Within a 200-meter range, even if the trainees move around in the venue, there will be no lag or disconnection. It also has 200 independent channels. If multiple teams are training simultaneously, each using a different channel, there will be no interference between them. The venue utilization rate has significantly increased. What’s more, the dual-teacher function is particularly convenient. When the instructor is presenting, the assistant can supplement explanations without competing for the equipment. They can directly speak, and the connection is very natural.
3.Long-lasting battery life + lightweight and portable, convenient for long-term use
The receiver of the E8 is only 18 grams in weight. The ear-mounted design fits the ears very well, and even if the trainees move around throughout the day, they won’t feel heavy. Even for practical training sessions, it won’t be hindered by hands-on operations. It uses PMU safety intelligent lithium batteries, which can last for more than 12 hours continuously without any problem. During the entire training session, there is no need for mid-session charging, making it much more convenient. The metal contact charging box that comes with it is also very convenient. When storing the equipment, simply place it in the box and it will automatically charge. There is no need to plug in each device individually. After the training session, it’s much faster to organize the equipment.
4.Simple operation + reliable quality, saves effort in organization
The operation of the Yingmi E8 is truly simple. Pressing one button to turn it on can automatically pair, and within a few seconds, dozens of receivers can be synchronized and connected. Even temporary staff without prior experience can learn to use it in just one glance. Moreover, each device undergoes 5 or more strict inspections before leaving the factory. Over the years, there have been no safety accidents, and it can also enjoy insurance coverage from the insurance company, making it very safe to use in high-intensity training scenarios.
