For frequent use, portability is a must-have, not an added benefit.
Many customers often focus on signal stability and battery life when purchasing, but they tend to overlook portability. However, when actually using the device in daily work, they realize that an unportable device with excellent parameters is just a waste of money. In practical use, portability directly affects work efficiency and user acceptance. For daily use scenarios, this is an indispensable necessity.
Why is portability so important? Those who have used it understand these practical pain points.
Tour guides who lead tours walk tens of thousands of steps in a day. Carrying a heavy audio guide device and a large storage bag doubles their physical exertion, and their energy for giving explanations is also scattered. Government and enterprise reception staff travel between meeting rooms, exhibition halls, and factories, and the equipment is large and heavy, making it inconvenient to carry and not looking neat. During outdoor field trips for students, teachers have to keep an eye on the children while managing the heavy equipment. Just moving the storage box alone is exhausting, and they can't even focus on leading the group.
More practically, the acceptance of the equipment by tourists and attendees depends on how uncomfortable it is to carry. If the receiver is too heavy and large, after wearing it for a while, the ears will hurt and the wrists will be sore. Most people will simply take it off. The explanation content won't be transmitted at all, and the money spent on the equipment is wasted. Therefore, portability is never an optional bonus; it is a hard requirement for high-frequency scenarios.
True portability is not just about making the device smaller; it's about being lightweight throughout the entire process: the device worn by the audience should be light, without causing fatigue after wearing for a long time; the transmitter used by the presenter should be small, able to be put in a pocket or clipped to the collar, freeing the hands; for bulk purchases, the storage and charging box should be small and lightweight, allowing one person to carry it away without the need for multiple people to move it, which would completely solve the pain points of carrying.

Yingmi 007B: Light and comfortable from start to finish
007B is Yingmi's specially designed model for portability. Whether it's the size of the body, the wearing method, or the accompanying storage and charging equipment, all are designed around "easy to carry and not troublesome". It is suitable for scenarios such as scenic area individual rentals, government and enterprise small-scale receptions, small student groups, and out-of-town business investigations.
A 5-gram ultra-light body, with no presence for a whole day
The receiver of Yingmi 007B achieves an industry-leading lightweight design, with a net weight of only 5 grams, lighter than a one-yuan coin. The body is so small that it is almost the size of an fingernail, and when held in hand or worn on the body, the weight is hardly felt. The transmitter weighs only 28 grams, similar in size and weight to a lipstick. It can be easily tucked into a pocket, waistband, or clamped onto the collar, taking up no space and causing no burden.
This lightweight design directly addresses the core pain points of wearing and carrying. When tourists wear the receiver to explore the entire scenic area, there will be no pressure on their wrists or ears, and they won't need to remove the equipment at will. When a tour guide wears the transmitter for a whole day, their shoulders and neck won't feel sore, and they can fully concentrate on giving explanations, truly achieving effortless use.

Mini storage charging box, can be carried away with a batch of devices with one hand
To meet the needs of bulk purchases by scenic areas and enterprises, 007B is equipped with an exclusive mini storage charging box, completely solving the problems of carrying and storing a batch of devices. This box is about the size of an ordinary laptop bag and weighs only 3.5 kilograms. A woman can easily carry it with one hand. When leading a group or changing venues, there is no need to ask for help to move it, and one person can handle it all.
The charging box uses contact fast charging, and it can simultaneously charge 30 sets of 007B, completing charging and storage in one step. No additional storage bag needs to be prepared. There are also silicone fixed grooves in the box, and the devices will not shake or collide when placed in it, providing shock and drop protection. Carrying this one box is enough to solve charging, storage, and transportation problems. It is particularly convenient for scenic area rentals and outdoor reception.
Adapted to multiple scenarios, lightweight and easy to use without sacrificing performance
Thanks to the all-round lightweight design, 007B can be adapted to various scenarios where frequent movement is required. For scenic area individual rentals, the receiver is small and easy to carry, and the charging box does not occupy storage space. For government and enterprise small-scale receptions, the transmitter is discreetly placed on the collar, maintaining a professional image. For study tour teams going on outdoor trips, teachers can carry the charging box with one hand, and students wearing the receiver can move freely without restrictions.
Moreover, 007B does not sacrifice performance for lightness. The core configuration is fully intact. It is equipped with Yingmi's exclusive anti-interference technology, with a transmission distance of up to 120 meters. Even when multiple teams use it simultaneously, there will be no interference or noise. The transmitter has a 28-hour battery life, and the receiver has a 30-hour battery life. It can be fully charged in 2 hours with fast charging, and there is no need to worry about power loss during high-intensity use throughout the day. The portability and practicality are well balanced.
