The ancient castle scenic area located in the suburbs of Barcelona, Spain, has been welcoming tourists from all over the world for years. When choosing wireless audio guides, they really made a big mistake. At first, they picked a small brand for the sake of cost, but within less than half a year, they discovered that – the equipment itself was usable, but the accessories were extremely scarce. The dozens of guide machines used every day in the scenic area needed to be charged, and the manufacturer only provided two simple charging heads. The staff had to take turns charging them until late at night. If a chest strap was accidentally broken, they would contact the manufacturer, who said there was no stock, and the cross-border express delivery would take a month or more. What was worse, several devices’ earphones were worn out, and tourists felt uncomfortable wearing them, leading to a continuous stream of complaints. Before the peak season last year, they replaced the wireless audio guide system with the Yingmi system, which came with a complete set of charging boxes, spare earphones, and storage boxes. Not only did this solve the charging problem, but later when replenishing accessories, it took only 3 days for the 3rd party warehouse in Europe to deliver them, completely avoiding any delays in reception. In fact, for foreign customers, the completeness of the accessories of the wireless audio guide directly determines the ease of long-term use. Choosing the right brand can avoid the awkward situation of “the equipment works, but the accessories are hard to find”.
I. Problems encountered when choosing wireless audio guide accessories
1.Only basic models are provided, and no practical tools
Many small brands only sell the main unit + simple headphones + power cord. They completely ignore the actual usage scenarios. For example, in scenic areas and museums, dozens or hundreds of devices need to be charged every day, but there are no batch charging boxes, so the sockets have to be filled up, which is messy and poses safety hazards; during cross-border transportation, there is no dedicated storage box, and the equipment gets knocked around during the journey, breaking before reaching the destination; even spare chest straps and ear covers, which are easily worn out, are not provided. When they break, they can only be used temporarily, and the tourist experience drops sharply.
2.Long waiting time for cross-border accessory replenishment
Small brands have no global inventory of accessories and rely entirely on cross-border direct shipments. When equipment breaks in foreign countries, wanting to replenish a charging cable or transmitter, the manufacturer would say “it has to wait for production”, and it would take 1-2 months. The equipment would remain unusable, wasting procurement costs. More troublesome is that some accessory specifications are not universal. Even if you want to find a substitute, you can’t find it. In the end, you can only abandon the old equipment and spend more money to buy a new one, resulting in greater losses.
3.Incompatible accessories, getting more expensive over time
Some brands’ equipment has different specifications for different batches of accessories. Last year’s charging cable is not usable on new equipment this year; ear covers, chest straps, and other easily worn-out small accessories can only be bought in the same batch. If the manufacturer stops production, you have to replace the entire set of equipment, and in the long run, it is a considerable expense.
4.No spare accessories, unable to handle emergencies
With a large number of tourists and high usage frequency of equipment, earphone cables getting broken or poor charging contact are common. Without spare accessories, when encountering such emergencies, some tourists will not be able to use the audio guide. Especially for international tourists, who don’t speak the language and have no audio guide, their experience will be directly ruined, and it may also affect the reputation of the scenic area.
II. Preferred Choice for Scenic Areas / Museums: M7 Self-sevice audio guide system
If you are in a scenario where long-term visitor reception is required, such as in scenic areas or museums, the M7 Self-sevice audio guide system from Yingmi is definitely reassuring due to its comprehensive accessories. This device is primarily designed for “ease of use and durability”. It uses the RFID-2.4G non-interfering star distribution system, and when a visitor approaches the explanation point, it can automatically sense and play the content. It comes with multiple language explanations and is designed with a chest strap for portability, which won’t cause discomfort even after long-term use. Its accompanying accessories have taken the concept of “practicality” to the extreme.
Among the core accessories, the HM-EB50 contact charging box is undoubtedly the “life-saving device” for scenic areas – it can simultaneously charge 50 M7 devices, with an input of 220V and an output of 5V-20A. It adopts an intelligent charging management mode, pre-charging first and then maintaining constant current and voltage, charging quickly while protecting the battery and extending the device’s lifespan. Moreover, this charging box can also have an ultraviolet disinfection function. After the headphones are disinfected, they can be used again, ensuring hygiene and peace of mind, especially suitable for crowded scenarios.
The HM-50S all-aluminum storage box is also very practical. The shell is made of all-aluminum material, with EVA shock-absorbing cotton and independent compartments inside. Each M7 and its accessories can be precisely positioned. Whether for internal transportation within the scenic area or for cross-border transportation, it can prevent drops, moisture, and wear and tear. The box also has a dedicated accessory area, where charging cables, spare chest straps, and headphones can be categorized and stored, making management extremely convenient.
In addition, the backup accessories for M7 are also comprehensive: high compatibility backup headphones (ear cups can be disassembled and replaced), wear-resistant chest straps (with different sizes available), extended charging cables (suitable for different charging scenarios in the scenic area), sufficient passive tags (if a certain explanation point’s tag is damaged, it can be quickly replenished), and even equipment cleaning tools and storage bags. Long-term and frequent use can also keep the device clean.
For scenic areas and museums, these accessories perfectly solve practical problems: dozens of devices don’t have to stay up late to charge in rotation, and the charging box is efficient and safe; cross-border transportation doesn’t need to worry about equipment damage, and the storage box ensures proper protection; easily damaged parts like headphones and chest straps can be replaced at any time without affecting daily reception; passive tags can be replenished quickly, and the absence of accessories won’t cause the explanation points to “break down”.
