The well-known historical museum in Italy used to be a headache for the staff. Every day, they had to accommodate several visiting teams from all over the world. The previously used wireless audio guides often malfunctioned during peak times – different teams’ voices would blend together, confusing the tourists. When they walked to the corners of the exhibition hall or the outdoor courtyards, the signal would simply drop, and the guide had to turn around to catch up with the tourists and repeat the explanation. What’s worse, many devices couldn’t last the whole day, shutting down due to power failure in the afternoon, thus spoiling the entire visiting experience. Later, they replaced it with the wireless audio guide from Yingmi, and these problems were finally completely solved: multiple teams could use it simultaneously without interfering with each other, and the sound was clear even from a long distance. The equipment’s battery life was still sufficient for the entire day of exhibition reception, and the tourists’ satisfaction rate increased by 60%. In fact, for foreign customers, whether the wireless audio guide is stable or not is the most crucial factor. Choosing the right brand can help avoid many pitfalls.
I.Select a Stable Audio Guide, Avoid These Common Troubles
1.Signal Unreliable, Frequent Disconnections in Complex Scenarios
Whether in the mountains of outdoor scenic spots, between multiple walls of the museum, or in the workshops of large factories, ordinary audio guides often experience signal interruptions. Especially when hosting international events or large museums, tourists are scattered for visiting, and if they are a little far away, they can’t hear clearly. The guide has to turn around and shout, and the tourists also get annoyed. The communication rhythm is completely disrupted.
2.Interference Among Multiple Teams, Chaos During Peak Times
In places like international exhibitions and large museums, several teams often use the audio guide simultaneously. Many brands’ equipment have unreasonable channel divisions, which often lead to interference and signal superposition. The guide’s voice is covered by other teams, and tourists can’t focus on listening to the explanation. The experience is particularly bad.
3.Poor Sound Quality, Inaudible in Noisy Environments
In scenic spots and factories with noisy environments, ordinary audio guides have poor noise reduction capabilities. The background noise is louder than the explanation. When encountering professional terms or multilingual explanations, the sound quality is blurry, and foreign customers are likely to misunderstand the core meaning, which also affects the communication effect.
4.Battery Life Drops, Unconvenient for All-Day Use
Many audio guides have a battery life of only 3-4 hours, which is simply not enough for all-day exhibition reception, scenic tour, or factory visit. Moreover, some devices have a slow charging speed and a troublesome charging method. When using them across borders, voltage compatibility issues also need to be considered. It’s no wonder it’s so inconvenient.
II.Choose the Right Model According to the Scenario, Good Stability
1.Museum / Business Reception: E8 Wireless tour guide system
If used in scenarios requiring high sound quality and stability such as museums or business inspections, the E8 wireless tour guide system from Yingmi is definitely a must-have. What makes this device most reassuring is that from the first sale to the one millionth unit, it has never had any major problems. It has truly withstood the test of the market for so many years.
It uses SOC embedded integrated digital noise reduction technology, which can filter out all the background noise. The explanation sound is particularly pure. Even in crowded museums, every detail can be clearly transmitted to the tourists’ ears. Its weight is only 16 grams, and it feels almost nothing when held in hand. The ear-hanging design fits the ears well, and tourists won’t feel uncomfortable wearing it for a whole day. It also solves the problem of hygiene in wearing.
In addition, E8 can support main and secondary dual talks or audio point selection, allowing flexible channel switching for multiple teams. Coupled with CRC digital encryption technology, it can effectively prevent channel interference. Even if 10 or more teams are using it in the same venue, they won’t interfere with each other, making it particularly suitable for various scenarios of cross-border reception.
2.Scenic Spot / Large Factory: 008B Team Tour Guide System, Resistant to Long Distances
If used in scenarios requiring long-distance transmission and noisy environments, such as scenic spots and large production factories, the 008B team wireless tour guide system is more suitable. It is equipped with advanced wireless amplification technology and independently developed intelligent noise reduction technology. Its wall-penetrating effect is particularly good, and the signal can be transmitted up to 280 meters at the farthest distance.
Even in the mechanical noise of the factory workshop or the open areas of the scenic spots, the speaker’s voice can clearly reach every listener’s ears. What’s more practical is that it supports two-way interaction. The presenter and the audience can ask and answer questions, and everyone can hear clearly, completely solving the problem that traditional tour guide devices can only transmit information in a unidirectional manner. Moreover, the device has extremely strong battery life. It can operate at a high intensity for more than 8 hours throughout the day without frequent charging, which avoids the inconvenience of frequent charging.
