When foreign customers purchase wireless presentation devices, they often make a mistake: they only focus on the performance of the main unit, completely neglecting the accessories. Once they use the equipment, they realize that they are missing a spare headset, the charging box is insufficient, or the sensor tag is broken and there's no replacement available; even more troublesome is that some accessories are incompatible with the main unit, and subsequent replenishment requires cross-border communication, which is time-consuming and energy-consuming. Whether in scenic spots or museums, if one wants to use the presentation device stably for a long time, the completeness of the accessories, their compatibility, and the convenience of replenishment are just as important as the performance of the main unit.
Yingmi is a brand of HEFEI HUMANTEK. CO., LTD., which is a national-level high-tech enterprise with its own SMT assembly factory. From the development and production of the main unit to the accessory supply, everything is controlled by itself. Unlike some small brands that produce the main unit themselves and purchase accessories from any factory, Yingmi's all accessories are developed and produced together with the main unit, fully compatible, without any awkwardness, and have passed EU CE and RoHS certifications, and go through customs clearance smoothly like the main unit. No matter if you buy a team presentation system, a self-service guide machine, or have special scene requirements, you can find the corresponding exclusive accessories, and no longer worry about "the main unit works well, but the accessories are hard to match".
For foreign customers, "complete accessories" is not about how many are there, but rather it must meet three requirements: First, it must be perfectly compatible with the main unit, and avoid compatibility issues when using; second, the material must be durable, as scenic spots and museums are used frequently, and replacing accessories is costly; third, the replenishment must be convenient, even if abroad, one can quickly receive the accessories. Yingmi's accessory system precisely hits these three core requirements.
Core accessories are the foundation for the normal use of the presentation device. Yingmi has exclusive core accessories for each model of the main unit, including charging, storage, and signal triggering, which can be fully equipped at once. For example, the M7C automatic sensing guide machine is equipped with a full-aluminum alloy dedicated storage box, which has a silicone groove, and 40 guide machines can fit perfectly. After closing the box cover, even if the device is shaken, it will not be damaged; there is also a contact-type charging box that can be powered by 220V electricity, with intelligent charging mode, which can both fast charge and protect the battery, and also has an option with ultraviolet disinfection, which is particularly hygienic for use in museums and scenic spots.

For example, the C7 touch + sensing guide machine is equipped with an inductive sensor tag that is particularly practical. It can support multiple signal numbers and uses a long-life low-power chip. Without pulling a wire for power supply, one battery can be used for 3 years, and it can be placed next to museum exhibits, and basically does not need to be taken care of; the E8 team presentation system's accessories are also thoughtful, the dedicated ear hook is ergonomically designed, not in-ear, and even after wearing for a long time, the ears will not hurt, and it is also hygienic; the charging base can charge multiple receivers at once, and the charging status is clearly visible, without having to guess whether it is fully charged.
Headphones and charging cables are consumables that tend to break over time. For foreign customers, the biggest concern is that the main unit is not broken, but the consumables are out of stock. Yingmi has already considered this, and all models of consumable accessories can be purchased separately, and bulk replenishment is also supported. For example, there are single-sided ear hooks and bilateral in-ear types, with clear sound quality and can block some environmental noise. Whether for teams or self-service use, they are suitable; there is also a portable USB charger, with a design of one charge for ten devices, powered by 220V electricity, which is particularly convenient for temporary power supply in scenic spots or as backup in enterprise exhibition halls. The charging cables, batteries, etc. are all produced by the same factory as the main unit, with the same quality. There will be no problems such as slow charging or poor battery durability.
Many foreign customers have special needs, and general accessories simply cannot meet them. Yingmi, as the original manufacturer, can customize accessories. This is particularly convenient. For example, when a large scenic area needs to transport equipment over long distances, a reinforced storage box can be customized, with an extra-thick aluminum frame and a shock-absorbing sponge inside. Even if it is transported across continents, the equipment will not be damaged.
Foreign customers choose Yingmi's accessories not only because they are all good, but also because there is guarantee from research and development to after-sales service, which solves the worries of cross-border procurement.
Yingmi's accessories are not added later. They are developed and produced together with the main unit. For example, the charging interface and signal frequency of each presentation machine are precisely matched with the corresponding charging box and sensing label, and there will be no situations like "poor charging contact" or "no response when the sensing label is triggered". Like the contact-type charging box of the M7C guide machine, the charging contact is perfectly matched with the main unit, and the charging speed is 30% faster than general charging equipment, and it can avoid damaging the battery due to overcharging.
Foreign customers have high requirements for product compliance. Yingmi's accessories, like the main unit, have passed EU CE, RoHS certifications, as well as dual Chinese CMA and CNAS tests. Whether exporting to Europe, America, or Asia, customs clearance is not a problem. The materials are also durable. For example, the aluminum storage box has undergone corrosion treatment, so it will not rust even when used in a seaside scenic area; the earphone cable is of high toughness and is not prone to breakage even after repeated pulling, and it can fully withstand the high-frequency use in scenic areas and museums.
Yingmi has accessory warehouses in several places around the world. When foreign customers need to replenish accessories later, they don't have to wait for shipment from China. They can just get the goods from the nearest warehouse. This is half the time compared to the industry average replenishment time. The after-sales service is more considerate. There is a 24-hour multilingual customer service online. Whether communicating in English, French, or German, there is no problem. If the accessories are damaged, cross-border repair is supported. After receiving the damaged accessories, they will be repaired and sent back within 10 working days. If you need to use them urgently, you can also send spare accessories first, without affecting normal operation.
Yingmi has already paired "main unit + accessories" packages for different scenarios. Foreign customers don't have to mix and match themselves. They can simply choose the package. It is convenient and efficient.
The package includes the E8 main unit, dedicated earphones, 48-position contact-type charging box (with UV disinfection option), backup batteries, and portable charger. The charging box can charge 48 receivers at once and can automatically disinfect. It is particularly convenient for batch management in scenic areas; the backup batteries can last for 10 hours, so there is no worry even if there is a long-term reception; the portable charger is small and can be used anytime by the tour guide when they are on the tour, even if it is far from the charging room.

The package includes the M7C main unit, a storage box with the brand logo, non-in-the-ear comfortable earphones, a small charging base, and waterproof sensing labels. The customized storage box has an exquisite appearance and can enhance the reception grade; the non-in-the-ear earphones are comfortable after wearing for a long time, and VIP customers will not feel uncomfortable; the small charging base is small and can be placed on the reception table, convenient for replenishing power at any time.
Q1: Can Yingmi's accessories pass the EU certification? Are they compliant for export to Europe?
A1: Absolutely compliant! All Yingmi accessories have passed the EU CE, RoHS certifications, as well as the CMA and CNAS tests for China. When exporting to Europe, America and other places, they pass customs as smoothly as the main unit. Now they are being exported in batches along with the main unit.
Q2: How long does it take for subsequent supplementary accessories to be shipped internationally? Can they be expedited?
A2: Yingmi has several accessory warehouses globally. If shipping nearby, it takes 3-5 days for Europe and major countries in America; if it needs to be replenished from China, it usually takes 7-10 days. You can also choose expedited logistics, and it will arrive in 2-3 days. Specific details can be asked from the customer service.
Q3: Can the accessories of different models of Yingmi earphones be used interchangeably? For example, headphones and charging cables.
A3: Some can be used interchangeably, such as USB charging cables and in-ear headphones. Most models can be used; however, core accessories like charging boxes and sensing labels are exclusive to specific models and need to be purchased corresponding to the model. When purchasing, clearly inform the customer service of the model, and you will be able to get the precisely compatible accessories.
Q4: How to handle the repair of damaged accessories? Do I need to send them along with the main unit for repair?
A4: There's no need to send the damaged accessories along with the main unit! Just send the damaged accessories back, and 24-hour multilingual customer service will follow up throughout the process. For accessories that break within 3 months, they will be replaced free of charge. For those that break within one year, they will be repaired free of charge. Cross-border repair is supported, so you don't have to worry.
