How to choose a multi-to-one wireless audio guide device?

When foreign customers purchase multi-to-one wireless audio guide devices, many of them tend to focus on the price - only to find out later that when multiple teams use it together, there will be interference, the sound becomes indistinct in noisy environments, it cannot last the entire day for a meeting, and it may not work due to voltage incompatibility. In fact, the core of a multi-to-one audio guide device is "stable sound transmission and suitable for the scenario". Choosing the right product is much more reliable than being tempted by low prices.

Having been in the audio guide device industry for 18 years, I have seen too many foreign customers get frustrated because they chose the wrong multi-to-one equipment. Today, let's take Yingmi audio guide devices, which have been exported globally for many years, as an example to discuss: What key points should foreign customers pay attention to when choosing a multi-to-one wireless audio guide device? How should they select models for different scenarios?

Ⅰ.The most annoying problem for multi-to-one audio guide devices in the foreign market

The multi-to-one mode seems simple - one main speaker and a group of listeners. But it really tests the strength of the equipment. The pain points reported by foreign customers are basically these four: If the equipment has poor anti-interference ability, when multiple teams use it together, the audience of Team A can hear the explanation of Team B, and the main speaker says one thing, the noise comes out one sentence, communication is directly disrupted. This is the problem that foreign customers often joke about, and it is the primary criterion for judging the quality of the equipment.

1.In noisy environments, the sound is unclear, and it's a waste of money and a nuisance

In factories, there are mechanical noises, at outdoor exhibitions, there are people shouting, and in large venues, there are echoes. In these scenarios, the sound of ordinary audio guide devices is directly covered over. The main speaker shouts, but the audience cannot hear the key information clearly. Buying the equipment actually reduces communication efficiency.

2.The battery life cannot last the entire day, and charging midway is extremely troublesome

International conferences and exhibitions usually last for a whole day, and sometimes even several days. If the audio guide device has a battery life of only 4-5 hours, it has to stop to find a power source for charging halfway. This not only delays the progress but also makes the reception experience greatly compromised.

3.International compatibility is troublesome, and voltage and languages are limited

Foreign customers are most worried about "getting the device but not being able to use it" - either the voltage is not compatible, and an adapter has to be bought separately; or it does not support small languages, unable to meet the needs of multi-national audiences; or even it has not passed international certification, and customs clearance becomes a problem. In the end, the equipment is piled up in the warehouse and wasted.

Ⅱ.Yingmi multi-to-one audio guide device: Solving scene problems in a practical way

Yingmi's ability to export globally for many years is based on its successful implementation of "stability and adaptability" in multi-to-one audio guide devices. Whether it is anti-interference, sound quality, or battery life, it precisely meets the needs of foreign customers. This is achieved through solid technical accumulation.

1. Anti-interference real skills: No interference even when multiple teams use it together

Yingmi's multi-to-one audio guide devices are all equipped with 4GFSK signal modulation technology and 200k ultra-small channel bandwidth, which can open up 100 independent channels. In simple terms, even if 100 teams are using it simultaneously in the same area, they can each listen to their own, and there will be no interference.

2.Noise reduction + high definition: Even in noisy environments, it can be heard clearly

For noisy environments, Yingmi has its own unique skills - SOC embedded integrated digital noise reduction technology, which can precisely filter out external noise and only leave the voice of the main speaker. Coupled with AI lossless original sound processing, even in noisy factories or crowded exhibitions, the audience can clearly hear every detail.

For example, at large mechanical industry exhibitions, the Yingmi 008A audio guide device performed particularly well. In the venue with dozens of mechanical equipment rotating simultaneously and multiple booths presenting technologies, this device relied on its strong noise reduction and high-definition sound quality to allow customers to clearly hear every technical parameter. The exhibitors said, "The communication efficiency is twice as high as that of the equipment used before."

3.Long battery life is convenient: No need to charge midway for the entire day

Yingmi has a brilliant solution for battery management - the PMU Secure Intelligent Lithium Battery Power Management Technology, which offers a much longer battery life than the industry average. Different models can meet the daily needs: The E8 transmitter can last for over 15 hours, and the receiver can last for 8 hours without any problem; The 008A and 008B transmitters and receivers can both last for 12 hours, which is sufficient for a 3-day exhibition.

What's more considerate is that the equipment supports fast charging. Even if you forget to charge occasionally, a short charge can meet your needs for half a day, and there's no need to panic about power loss in the middle.

4.International Compatibility is All Covered: Voltage, Language, and Certification are Stress-Free

Yingmi has already thought about the compatibility issue for foreign customers: The charging modules of all one-to-many presentation devices support a wide voltage range of 100V-240V. Whether it's 220V in Europe or 110V in America, you can plug it in and use it right away. It is equipped with the HM8.0 multilingual sharing platform, which has 8 mainstream languages by default and can be customized for smaller languages as needed. It can meet the needs of multi-national audiences.

More importantly, all devices have passed the EU CE and RoHS certifications, and have undergone dual inspections by China's CMA and CNAS. They can smoothly clear customs in most countries around the world, without the need to worry about certification issues.

III. How to Choose for Different Scenarios? Yingmi Models Fit Precisely

The requirements for one-to-many presentation devices vary in different scenarios. Random selection will only waste money. Based on the common scenarios of foreign customers, these models can precisely fit:

1. High-end international conferences, VIP receptions: Choose the E8 all-in-one presentation device

This is Yingmi's star model. It weighs only 16 grams and has an all-in-one design that is both fashionable and high-end, perfectly matching the tone of high-end conferences. It supports both main and secondary dual talks and audio playback, not only for one-to-many presentations, but also for multi-person collaborative presentations.

2.Factory visits, noisy exhibitions: Choose the 008A presentation device

If the scene is noisy and requires long-distance explanations, the 008A is the right choice. Its wireless amplification technology is particularly powerful, with a communication distance of up to 280 meters, excellent wall-penetrating effect, and even in large factories with different workshops, the signal will not be interrupted.

Moreover, this device is particularly durable, with good dust-proof and shock-resistant performance, suitable for complex environments such as factories and outdoor exhibitions, and doesn't require careful care.

3.Interactive training, seminars: Choose the 008B two-way presentation device

If one-to-many presentations require audience questions and interaction, the 008B is the best choice. It is currently the most advanced wireless two-way presentation device on the market, allowing the main speaker and audience to interact, with one-to-one questions and answers within the team, and everyone can hear clearly. It is particularly suitable for enterprise training, academic seminars, and other scenarios that require communication.

4.Daily receptions, long-term wearing: Choose the R8 ear-hanging presentation device

This device uses Ergo ergonomic non-in-the-ear design, and the audience won't feel pain in their ears even after wearing it for a whole day, and it also solves the hygiene problem. Its sound quality and stability are no worse than other models, suitable for daily museum tours, regular enterprise receptions, and other high-frequency usage scenarios, with extremely high cost-effectiveness.

IV. Yingmi's Additional Benefits: Not Only Good Products, But Also More Convenient Services

When foreign customers purchase equipment, they are not only concerned about the product itself but also the service. Yingmi's 9G full life cycle service is reassuring from pre-sale to post-sale:

Pre-sale: 90 seconds can respond, with 1,000+ real case references, and it also supports free sample testing - customers can test the device in their own scenarios first, and if satisfied, they can place an order immediately, with no risks; During the sale: On-site inspection can be provided for urgent orders, and they can be dispatched on the same day; After-sales: Professional technical support is available, even in foreign countries, most problems can be solved remotely, and the device can enjoy lifetime guarantee. More importantly, Yingmi has its own SMT assembly factory, where it controls the entire process from R&D to production. Each piece of equipment must pass five tests (high temperature, low temperature, vibration, sound quality, battery life), ensuring high quality. From the first unit to the 1 millionth unit, no safety incidents have occurred.
