The core pain points of one-to-many explanations: foreign customers care most about these 3 points
One-to-many tour guide system is different from one-to-one. It needs to take into account multiple receivers, wide coverage, and batch management. When choosing equipment, foreign customers are most afraid of encountering these 3 problems, which are also the key to judging whether the equipment is good to use.
Pain point 1: Poor anti-interference + Crosstalk, chaos in multiple teams at the same time
In popular tourist attractions and large exhibition halls abroad, several teams often give explanations simultaneously. Many cheap devices have poor anti-interference capabilities and can be affected by mobile phone and radio signals. Even worse, different teams will have crosstalk - the main speaker speaks seriously, but suddenly another team's explanation comes out in the listener's ears, which is an extremely bad experience and seems unprofessional. This is a real disaster for customers engaged in enterprise receptions and scenic area guiding.Pain point 2: Short transmission distance, need to "shout loudly" in large venues
One-to-many often needs to face large venues, such as foreign large factories and outdoor scenic areas. The main speaker can't always stay close to all the listeners. Some devices have insufficient transmission distance and become inaudible when the distance is slightly farther. The main speaker can only repeat, which is tiring and affects efficiency. Even worse, when there are obstacles like walls and trees, the signal directly weakens, and the people behind can't hear at all.
Pain point 3: Difficult to carry and store in batches, heavy burden for cross-border group tours
Most foreign customers need to use in batches, dozens or even hundreds of devices. Without good storage and charging equipment, when carrying, they have to pack separately, and when distributing, they have to debug one by one. When storing, they have to charge one by one, which is very time-consuming. Cross-border group tours are even more troublesome. The heavy boxes not only increase shipping costs but also easily damage the equipment during transportation.
Yingmi E8: Precisely solves the pain points of one-to-many, suitable for all scenarios abroad
Yingmi E8 is optimized based on thousands of one-to-many scenarios abroad. It has strong anti-interference, multiple channels, and won't have crosstalk even when multiple teams are on the same stage. It also has 200 independent channels, supporting up to 100 teams to use simultaneously in one place. Each team has its own dedicated channel, and it can be matched with one click. Even in crowded exhibition halls, explanations can be clear and refreshing.
1. Stable transmission + sufficient distance, no pressure in large venues
E8's marked communication distance can reach 200 meters. In actual tests in open areas, it sounds clear within 300 meters. There have never been cases of audio interruption or blurring. Even in factory workshops or large scenic areas with trees and walls blocking, it can be understood within 150 meters. The main speaker can freely move and give explanations without worrying about the back row listeners not hearing clearly. Moreover, its sound transmission has no delay and the sound quality is close to the original, making it sound as natural as the main speaker speaking right beside you.

2. Lightweight + Good storage, super convenient to carry and distribute
E8 feels almost weightless in hand. The receiver is only 16 grams. It has an earpiece design and is made of soft silicone material. It won't irritate the ears even after wearing for a whole day. Tourists and participants can all accept it. The transmitter is just the size of a palm, fitting easily into a pocket or hanging around the waist without taking up any space. The presenter can carry it without any burden.
It's even more convenient for mass storage. The matching contact-type charging storage box can hold 50 devices at once and also charge them simultaneously. The box has a metal casing, with shock-absorbing cotton and independent slots inside. The devices won't get damaged when placed inside. The key point is that it weighs only 5 kilograms, making it easy to carry in a suitcase when traveling internationally. It's not cumbersome to lift either. Charging is fast, and it can fully charge 50 devices in just 2.5 hours. Charging once at night is sufficient for the entire day's use the next day.
3. Simple operation + Long battery life, even beginners can quickly get the hang of it
The E8 operation is not complicated at all. The transmitter has a full-function display screen, showing the battery level, channel, and volume clearly. The presenter can adjust it without learning. The receiver automatically matches the previous channel after turning on. The listener can start listening by simply putting it on, turning on the switch, and taking it out. There's no need for manual pairing. It saves a lot of time when distributing in batches, especially suitable for large-scale meetings, scenic area tours, and other scenarios that require quick distribution.
The battery life is also reliable. The transmitter can be used for over 15 hours after being fully charged, and the receiver can last up to 8 hours. For short-term explanations, a single charge can last for two to three days. Even for long outdoor tours or multiple meetings, it's easy to recharge quickly with the storage box. There's no need to worry about power outages in the middle.
