The headset box is very stylish, color and headphones are also very uniform, the front is a transparent plastic shell, you can clearly see the inside of the headset.
Open the package, the inside of the accessories are shown below, there are packages, there are USB lines, earplugs, etc., there are instructions, this manual in English, fortunately simpler, but also to see a probably.
The green part of the earphone is a titanium alloy frame, which can reduce the weight, increase the firmness and flexibility, how to bend on how to bend, you can make a circle, can you?
On the right earpiece side there is volume +, - key control and USB charging port
There is a multi-function button on the left earpiece that can answer the phone and control the fast forward and pause of the song.
The general structure of the headset is like this, more details we will not introduce one by one, because it does not affect the use.
For bone conduction, most people may have heard about it in Google Glass's related news. I believe more people still don't know what a ghost it is. Here we briefly talk about it. We use the graph provided by the official AfterShokz at a glance as follows:
To put it simply, there are two ways we usually hear sounds. One is that the sound is transmitted through the air into the human ear, and then through the tympanic membrane to our auditory nerves; there is also a way of bone conduction through the skull directly into the auditory nerves. . If you still do not understand bone conduction, then plug your ears, and then open your mouth to speak, you will find no matter how small the sound will be clearly heard, this is mainly through the skull into the auditory nerve, that is, bone conduction.
Things are good or bad, used to know. Then the appearance of cool, advanced technology is ultimately to serve a good experience, this headset is not good? Personally I think we should talk about two aspects. One is the experience of listening to music in a quiet state, and the other is the feeling in sports. Aside from the technical parameters, the experience is too subjective. The main technical parameters are as follows:
Here we talk about the actual feelings and parameters, the first is a static listening, we use AKG's K420 as a comparison, with the main HiFi Meizu MX Pro5 play music.
Originally wanted to list the audition song list to talk about specific feelings, but I found it unnecessary, because with a bone conduction headset listening to songs a bit strange, and the traditional headset is very different. K420 is a low-end classic earphone. If we measure bone conduction headphones according to the standard of our evaluation of traditional earphones, we can say that the sound quality is very poor.
Is this a problem with the headset? Not exactly, we said above what bone conduction is, and here we have to come up with this one. The sound we hear is the effect of the superposition of bone conduction and air conduction. If we record our own voice with a tape recorder and listen to it, we will not feel like our own voice, because it is only the sound of air conduction. The recording and restoration of our songs and the tuning of the headphones are all about air conduction and vibration. We have become accustomed to such songs, and it is natural for us to introduce such songs into our brains through bone conduction. of.
The limitations of Bluetooth on the sound quality and the bone quality of our bone conduction headphones are not ideal. This is a bone conduction headset that has to face a reality for a long time. It does not mean that AfterShokz is doing poorly.
In addition, some people say that bone conduction headphones leakage problem is more serious, on the hands of this, and there is no legend so powerful, it should be said that the control is good, much better than the K420 leaking king.
After listening to the feeling of static and then again to exercise, here is a pace I run with bone conduction headphones (not jokes, winter in a semi-dormant state)
Tell us about the feelings of running:
Because of the nature of bone conduction, it is decided that listening to the song while the ears to the outside world's voice is completely unblocked, this is very important, especially when the road is running, the traditional headset is not even recommended when the sports headphones are running. Band, but the bone conduction headset is not a problem, the earphones standard earplugs, but do not take the road when running, other moments;
Running longer will drain a lot of sweat and the headset will not be affected;
Titanium is a very good control of the weight of the headset in all aspects, but also more comfortable to wear, but personal running time is a bit longer, plus the pre-run warm-up and stretching after running about one and a half hours, wearing the whole The earphone found that it would feel oppressive to wear for more than one hour, and there will be a little discomfort in the vibration of bone conduction (maybe a long time will adapt);
After running for a full marathon, there is no problem, and the actual measurement can exceed 6 hours. Of course, this is related to the size of the open volume.
Aftershokz had heard of it, but it was the first time I had used a bone conduction headset, which was very different from our traditional headphones. If we use the traditional headphone standard to judge him to be unfair. Here's a summary of personal experience, strengths, and weaknesses.
Advantages: can run with the road (running) headphones, sports with a much higher security than the traditional headphones, titanium alloy material makes the headset sturdy, flexible and lightweight, it is also more comfortable to wear;
Disadvantages: The entire English manual needs to be improved. Personal advice is in multiple languages. A totally different listening experience from a traditional headset will result in a poorer sound quality and is not suitable for listening to music at ordinary times;
If you sum it up in one sentence: Aftershocks bone conduction headphones titanium is not the same, was born for sports!
