If you are a flight attendant, you should be careful: Mi's smart audio glasses are coming in

If I were a flight attendant, everyone who has flown knows that during the takeoff and descent stages of an airplane, everyone needs to straighten their seat backs, fold up the small table, open the sunshade, and remove their headphones. These regulations are all for safety reasons, and as a flight attendant, I have a responsibility to inspect them one by one. If I don't follow them, I have to remind and persuade them, after all, the regulations are like this.

Then I walked up to a gentleman who was not wearing headphones, but I could clearly hear a faint sound of music in this direction. How should I judge and do at this moment?

First of all, I would suspect if he had turned on his phone speaker. I might ask him, "Sir, are you playing music outside your phone? Could you please turn it off when the plane is descending?" But after saying that, I feel something is wrong. His phone is in his hand, but the sound comes from his head, and he definitely doesn't wear headphones. He doesn't wear anything else on his head except glasses, is it... is it from his glasses???

Yes, this sound comes from glasses - Mi's smart audio glasses with glasses legs that can produce sound.

We have talked before, and sometimes the progress of technology is truly thanks to our human greed. With good things, we want better things. Previously, I used to listen to street vendors selling earplugs, later I listened to hundreds of earplugs, and later I spent tens of thousands of flowers. And not only does listening to music require better sound quality in the vertical dimension, but also in the horizontal dimension, we are thinking about how to make it more convenient in form. The wearability of electronic devices has been a recognized trend in the industry in recent years. However, no matter how beautiful a concept car is, it may not necessarily be suitable for driving on the road. No matter how interesting a concept product is, it must first solve a few problems in order to truly benefit ordinary consumers.

For example, the concept of smart audio glasses is very easy to understand, which is to install speakers and microphones on the legs of the glasses. People can wear them like ordinary glasses, listen to music, answer and make phone calls, and can execute some voice commands. However, to make a product that everyone can accept, first of all, you need to pay attention to your glasses legs - while ensuring battery life and functionality, they cannot be too thick or heavy, and must be similar to ordinary glasses legs; Secondly, your sound quality cannot be very uneven, and with the addition of the first condition, this is actually not that simple (as discussed later); Next, as an ordinary pair of glasses, you need to pass the exam. Don't say that I can only make flat lenses that cannot be matched with lenses with degree, so it's not practical; And the battery life should not only be sufficient, but also the charging should not be too cumbersome; Finally, the selling price must be as appropriate as possible.

To be honest, at the beginning of receiving this set of Mijia smart audio glasses, I didn't set my expectations too high. I used a relatively calm attitude of saying, "Let's see how it works" to complete the unpacking and initial experience: the frames are divided into several styles, and Mijia staff asked for my myopia data and then matched one of them with myopia lenses, The operation of self optometry and purchasing glasses online with data is now very mature, and the matched glasses are very suitable to wear; The rest of the lenses are flat, and the main frames of several glasses are carefully crafted and made of materials. We cannot compare them to Lindbergh or anything else. Considering their actual price, we are already quite conscientious.

There are two tenons on each leg of the mirror, and this self-developed hinge patent design is very mature. When combined with the mirror frame, it can be said to be simple and reliable, and can be easily removed. The left leg of the mirror has two openings, one large and one small, while the other has an additional set on the right (meaning the microphone is located on the right). This actually becomes interesting because the leg of the glasses is located above the ear canal, so everyone subconsciously thinks that the main sound outlet of this product should be designed below the leg of the mirror, as close as possible to the ear hole, right? However, Mijia's product has taken the opposite approach, with a larger tuning hole design. The effect will be discussed later.

Previously, it was said that this product cannot be made clumsy or heavy, otherwise consumers will not be able to wear the glasses you really use that day. The legs of Mijia's intelligent audio glasses are visually no different from common sheet glasses. Without a reminder, it is difficult for others to notice that you are wearing an "intelligent product", and the aesthetic appearance is also quite impressive. In terms of weight, I have weighed two pieces, totaling 23g. In addition, my frame weighs 43g (starting from the official nominal 38g, as different main frames and lenses of different degrees can cause weight differences) - in daily life, the weight of most people's glasses is in the range of 20-30g, while the weight of plate frames can be 30-40g. Therefore, although this weight cannot be said to be very lightweight, it is still qualified to be included in the weight range of normal glasses.

The charging part is great. There is a cable inserted into the Type-C cable inside the packaging and then two small sleeves are turned out. These two small sleeves are not separated from each other, and when they are wrapped around the end of the glasses leg, they will automatically charge. This design is very foolproof, and the Type-C cable is available everywhere, and the overall length is relatively short and sharp, so there is no need to wrap it around, which is very convenient.

In terms of battery life, this pair of glasses has a standby battery life of up to a week, a daily battery life of 22 hours, continuous listening to music for 10 hours, and continuous phone calls for 7 hours. In practical use, I wear it during the day and take it off at night (it has a wear detection function, which automatically pauses the music and enters standby mode), which can basically be recharged once in two days. And if you listen to music and make phone calls frequently, then it's no problem for a whole day.

Calling is an excellent feature of this pair of headphones, and the dual microphone beam AI call noise reduction algorithm is used in many real wireless applications. However, when placed on smart glasses, it is obvious that copying and pasting cannot be completed. After all, the usage mode has undergone a substantial change, and external interference factors will also increase. It requires more effort to achieve better results. The actual measurement shows that the communication quality of this pair of glasses is clear and stable, and it is still capable in relatively noisy environments (the scene noise reduction algorithm is well done), especially in terms of wind noise resistance. It is difficult to defeat small wind noise, but of course, it is powerless when the wind is strong, which is also determined by its innate wearing method. Another thing is the experience of using it to make phone calls. In fact, it's easy and interesting because you think, nowadays, phones are very heavy, right? Over 200g are everywhere, and when you hold this weight by your ears, it's not your ears but your arms that are tired. And in ear earplugs (including in ear TWS), although they don't need to lift the phone, appear less relaxed because there is something blocking the ear. Mi Jia's intelligent audio glasses are completely free from these drawbacks. You can even listen to birds and insects chirping in the park while chatting with friends from afar for two hours. The laughter of nearby people also reaches your and TA's ears and eyes along the phone

In terms of other functions, IP54 waterproof is very practical and reassuring (after all, the usage environment of the glasses determines that they need to have waterproof and dustproof functions to be good, otherwise a malfunction caused by rain can be more annoying?); There are ultra long touch operation areas with raised edges on both sides, making blind operation quite convenient. Long press to open the voice assistant, double click to pause and play (answer/end phone), slide to adjust the volume, and support custom gestures; It supports dual device connectivity, allowing for arbitrary switching between Android, Apple, and even Windows systems; It also supports the function of searching for glasses. The question "Where are my glasses?" that I often ask myself after taking a shower has finally yielded a better answer.

Having said so much, let's talk about sound quality - in fact, there's no need to put the issue of sound quality at the end of this product. It can only be said that it's an occupational disease due to writing habits. I apologize for any inconvenience caused~

This is a pair of intelligent audio glasses with a sound quality that exceeds everyone's expectations. All the people I meet who are curious about this pair of glasses, their reactions after wearing it are basically: "Oh, this sound is better than I thought!" and "The sound is not bad. I myself had the same reaction at the time, and even after long-term wear and use, I still quite recognized its sound quality.

Preliminarily: The inherent advantage of this product is that the sound field is absolutely large. If you play with the acoustic design and surround sound algorithm and control the temperature well, it may create an extremely natural and traceless sound field (this product truly achieves this). Moreover, due to the location of the sound source in your temples, the feeling of the field cannot be given by other earphones, Some music may even have a strange sensation of a fairy singing around you. However, the inherent defects of this type of product are also obvious. It cannot provide a rich sense of mid to low frequency energy. During the transmission process, a lot of mid to low frequency energy will be lost. If you compare it with the in ear low frequency sense of quantity to the mid frequency fullness, it really cannot be defeated. This needs to be explained first.

The low-frequency of Mijia's intelligent audio glasses can only serve as a cushion for the atmosphere, and the word 'plump' is destined to have nothing to do with it. The low-frequency details are still divided neatly enough; On this basis, its mid range is quite well done, with a clear and contoured vocal shape that expresses as much as possible, mainly with a certain degree of softness and separation of instruments; The clear and dynamic high-frequency style makes the entire listening experience more melodious and comfortable, and the mid to high frequency part has corresponding good details to express - among similar products I have heard of, its sound quality is obviously excellent, and most importantly, they seem to think more clearly.

Because this product ultimately aims to return to the point of 'whether consumers sound good or not', the points to be studied include but are not limited to the physical conduction effect of the glasses legs on the vicinity of one's temples, the quality and properties of the speaker itself, the acoustic image caused by the mirror leg shell, and the comprehensive auditory effect of algorithms on the listener, among others, It's not just about pointing two speakers in the direction of the ear canal - the hassle here is actually more complicated and systematic than making in ear earplugs. To achieve a final result where everyone says' the sound is good ', it must require a huge amount of effort to achieve.

And the tuning focus of this product is also particularly clear: it is to make the mid range vocals sound good, rather than unnecessarily adding low frequencies. This method of adding low frequencies is twice the effort, but adding mid frequencies, especially improving the final listening experience, is crucial - never let the mid frequency get stuffy or pricked, and give people a clear, comfortable, and non irritating vocal performance while overall melodious. This is the key in this type of product, and it is not easy to maintain, Only when things like the Mi family are aligned, can they bring about the effect of "my friends say it's better than they imagine".

And its leak proof sound has some effectiveness, not to mention its astonishing effect. It ensures that when you play music in the office, if you turn down the volume, the people around you will not realize that you are listening to the song. However, if you turn it up to the maximum, it will inevitably occur in a quiet environment - colleagues are looking around to find where this strange sound source comes from. To be honest, its maximum volume is not too high, so it should be considered to limit the maximum volume and try not to disturb others, right?

In short, smart audio glasses are not only able to block one's listening to the external environment, but also can relax and add a little beauty to one's daily life BGM. They can not only answer and make calls without holding the phone up to the ear or blocking the ear canal, including when WeChat rings, you can also hear a prompt here (belonging to grabbing the job of a smart bracelet) to avoid missing out. This experience is really interesting. This type of product may not seem that difficult, but to achieve the eyewear part, it is also very appropriate (which requires us to talk to the eyewear manufacturer about the supply chain. Fortunately, we are in China, where the mature supply chain and production of eyewear are all located). The material design of the eyewear legs is excellent, and the volume and weight are similar to ordinary eyewear. On this basis, the sound quality is relatively good, the battery life is sufficient, and charging is convenient. Additionally, it is also required to have good phone calls, Waterproof and dustproof, easy to operate, and ultimately priced below a thousand yuan?

Is that difficult?

At the end of the article, some people may have thought, are these glasses too noisy to listen to music in a slightly noisy environment?

No, you can still listen to music at the highest volume on the plane. Although the environment was quite extreme, I did try it out of curiosity. Moreover, due to the loud noise in the cabin, the person sitting next to me didn't notice me listening to the music for a short time. It wasn't until the plane was about to drop off that a flight attendant came over with doubts in her ear

Yes, of course the flight attendant at the beginning of the article is not me, but the person she looked at with strange eyes was me. Wow, ha, ha, ha, ha, ha
