Which band of wireless tour guide device is good

Just last month, we received a client who was involved in international academic exchanges. They were preparing for a 200-person cross-national conference, with participants from over a dozen countries. They thought that all the preparations were in place, but they ran into problems with the wireless tour guide device. They initially chose a common model available on the market, but halfway through the conference, it started to malfunction: several parallel discussions were taking place simultaneously, and the signals from different tour guide devices interfered with each other. Sometimes the participants could hear the voices from another discussion group, and sometimes there was no sound at all. Many foreign participants were not familiar with the equipment operation, and they spent a long time trying to figure out how to change the channel, resulting in missing key speeches. The most troublesome issue was the battery life. During a conference that lasted from morning to afternoon, one-third of the presentation devices ran out of power before the session ended, and they had to use a power bank to make do, disrupting the overall conference rhythm.

Later, our colleagues recommended Yingmi to them, and after switching to our wireless tour guide device, no more issues occurred in the subsequent conferences. Maybe many clients are not aware of it, but Yingmi has been in the tour guide device industry for 18 years, always focusing on the actual needs of conferences and exhibitions. Among them, the K8 wireless tour guide device precisely addresses the most common problems encountered in conferences.

I. Four major pain points in conference scenarios involving wireless tour guide devices

Whether it’s a cross-national conference, an enterprise annual meeting, or an industry seminar, when people use wireless tour guide devices, they encounter similar problems. These minor troubles may seem insignificant, but they significantly affect the participant experience and conference efficiency. They mainly concentrate on four points:

1.Unstable signals

Most conferences are held in enclosed venues, where there are already wireless signals such as WiFi and Bluetooth. Ordinary tour guide devices are easily interfered with, causing intermittent audio and even interference to other channels. Key conference information simply cannot reach the participants’ ears, which is equivalent to doing a useless presentation.

2.Too complicated operation

Many tour guide devices require manual channel adjustment and pairing. If the participants are all Chinese, they can figure it out, but in international conferences, the participants do not understand the language, and they have no idea how to operate the equipment. This wastes time and disrupts the conference process.

3.Battery life and management issues

A complete conference, including sign-in, intermission, usually lasts for 8 to 10 hours. Ordinary tour guide devices simply cannot last that long. Charging during the middle part is inconvenient; moreover, after the conference, dozens or hundreds of devices are scattered everywhere, and charging and storage require a lot of time for organization, increasing the burden on the staff.

4.Uncomfortable wearing

Participants need to wear the tour guide device throughout the conference. Some in-ear models can cause ear discomfort after wearing for a long time. Participants are preoccupied with the discomfort and cannot focus on the meeting, resulting in a significant reduction in presentation effectiveness.

II.Based on these requirements of the conference scenarios, we highly recommend the Yingmi K8

It’s not because it is our product, but because every design of the K8 precisely hits the needs of the conference scenarios. The feedback from customers who have used it is very good:

1.Strong signals

Let’s start with the most concerned issue of signals. The K8 uses the 860MHz-870MHz new generation mobile high-frequency band, avoiding the interference frequency bands of daily WiFi and Bluetooth. Even if there are 6 or more teams using it simultaneously in the same venue, there will be no interference or disconnection; moreover, its communication range can reach 200 meters. Whether it’s a large banquet hall, multi-level venues, or irregularly laid-out meeting rooms, every participant from the podium to the back corner can hear clearly.

2.Easy operation

The operation is also very convenient. K8 has an automatic binding function. The receiver doesn’t need to manually adjust the channel or be paired separately. As long as the transmitter is unlocked and turned on, the receiver can automatically match when it gets close. Participants can simply pick it up and put it on to listen. Even foreign participants who don’t understand Chinese or are not familiar with the equipment can easily get started without additional explanations from staff.

3.Battery life and management

In terms of battery life and management, K8 is also well thought out. The transmitter and receiver can be used continuously for 10 hours after a single charge, which is just enough to cover a full day of meetings. There is no need to stop to charge halfway. The accompanying charging case comes in two sizes: 36 units and 48 units. After the meeting, you can put all the equipment in it for simultaneous charging and unified storage, eliminating the need to search for sockets separately, which greatly saves the staff’s organizing time. There is also a dedicated aluminum storage box that can hold 50 sets of equipment and accessories. Whether it’s for local transportation or remote meetings, it’s very convenient. It can also protect the equipment from being bumped.

4.Comfortable wearing experience

The wearing experience is also beyond words. The receiver of K8 is of an ear-hanging design, not the kind that goes into the ear. It weighs only 22 grams and is very lightweight when worn on the ear. It fits the ear cavity without pressing on the ear. Participants won’t feel uncomfortable or sore after wearing it for a whole day, and they can focus on listening to the entire meeting.

III. The comprehensive solution provided by Yingmi for conference needs

We know that different conferences have different requirements. Having good equipment is not enough. Yingmi has prepared three comprehensive solutions for conference scenarios to completely solve the problem of explanations.

1.Multilingual conferences

If it’s a multilingual conference, such as a cross-border conference or an international forum, K8 supports pre-recording of multilingual explanation audio. Before the meeting, we will set up the corresponding channels for you. When the meeting starts, participants can simply put on the receiver and choose the language they are familiar with to listen. No need to hire additional human translators. This saves costs and ensures that every participant can understand the meeting content.

2.Large-scale conferences

If a large-scale conference requires multiple explainers, such as an enterprise annual meeting or an industry summit, K8’s transmitter supports dual-person simultaneous explanation. The main explainer is responsible for the core content explanation, and the assistant explainer supplements the details. With the cooperation of the two, the information can be conveyed more comprehensively and in-depth, improving the explanation quality, and also avoiding the fatigue of a single explainer.

In addition, many customers are worried about equipment failure on the day of the meeting. You don’t need to worry about this at all. We will conduct on-site signal coverage tests based on the size and layout of the meeting venue in advance, adjust the equipment parameters to ensure that the equipment can run stably on the day of the meeting. At the same time, Yingmi also provides a 2-year warranty service (excluding shipping costs). If any problems occur during the use of the equipment, just contact us, and we can provide timely after-sales support, so that the meeting progress will not be affected by equipment failures.
