As a professional headphone technician, let me share with you. Even if it's headphone Xiaobai, you can distinguish the quality of headphones by yourself, and you can also choose a good headphone for yourself.~

First of all, ordinary people will experience three mistakes when choosing earphones:

1. Only listen to the bass to judge whether the earphone is good or not

This is absolutely wrong! Because bass is actually the most easy to tune, there is no technical content, small main debugging. Because many people who don't understand earphones think that the earphones with the most outstanding bass are good earphones. So now, you can buy a very pompous bass headset from any local stall. Why do so many people think that low pitched headphones are good? Because they all misunderstood the true face of the good voice. When the bass is heavy, the high and middle notes will be weakened, and the sound will be seriously distorted, making the ear uncomfortable.

2. The louder the sound, the better the earphone?

Not always! A loud earphone only means a high loudness, not a good quality. This involves an important premise: no

If you like yourself and enjoy the music time quietly, you'd better choose a earphone with good sound quality and close to the original sound. If you are often in some noisy environment, or like listening to radio or Internet novels, you can also choose a earphone with high sound quality, but you should pay attention to the bad influence of the sound Conference on the eardrum. Wear it carefully. Usually try not to turn the sound too big, and do not wear headphones for a long time.

3. Is beryllium earphone toxic?

In a large speaker, beryllium metal is often placed on the top of the sound as a sphere part, which can convey the purest and clearest treble. So now there are some earphones with good sound quality on the market, and beryllium metal is used as the diaphragm material.

But because beryllium is very expensive, a 38 mm diameter beryllium metal sphere costs 1000 US dollars. So the smart business came up with the idea of plating beryllium metal on the diaphragm to form beryllium coating diaphragm, which can control the cost and achieve the desired sound quality effect at the same time.

However, the problem comes. Du Niang tells us that beryllium is toxic and carcinogenic!

However, in fact, beryllium is toxic in the state of gasification and dust, but the solid beryllium is absolutely non-toxic. The melting point of beryllium is 1700 ℃ +. Naturally, we can't make it gasified or dust at all, so we don't need to worry about poisoning.
