Written in the front, the individual did not toss HIFI, did not toss the speakers and headphones, not what gold ears, so this article will not be too professional, used a lot of headphones, can be more emphasis on gaming headphones, this article is just a Ordinary users have some personal opinions on the Meizu HD50. If you want to see special evaluations, please bypass. This article is not suitable for you.
Meizu's first headset - HD50, it has a lot of labels, 399 yuan, bio-film, metal trend, ... ... so that it is also a lot of forcing. Do not say gossip, first come to a simple box.
What I received was black and silver, and the packaging style was simple and generous.
The box is mainly silver, with HD50 printed on the front.
On the back is some information on the headset, looked at, or very detailed.
This packaging style is very strong, can be very good protection of the headset from brute force express destruction, but when the demolition is also more troublesome, after removing the sealing film did not open the package a few times, and finally with a tool to open the box.
After opening the package, I saw a plastic shell with the words "For the lovely ones Designed by Meizu" printed on it.
There are HD50 instructions and a headset storage package.
The workmanship of the storage bag is not bad, the hard shell design can effectively protect the headphones in the bag, and the hand feels good.
Open the admission package, and finally see the protagonist of today's Meizu HD50.
Silver and black version of the overall feeling pretty good, printed above Meizu's new LOGO, after a period of time to adapt, feeling better than just released a lot of time, in addition to headphones included in the package, there are two adapters and headphone cable.
After the release of the Meizu HD50, I felt that this headset had some familiarity and I couldn't remember what I had seen. After reading the official website, I realized that it was no wonder that I was familiar with the problem of bloodlines. I had to sigh. .
SLR destroyed life, HIFI poor three generations, SLR did not use several, HIFI is rarely contact, as a poor person Although many used Walkman and headphones, carefully want to come to hand really not a HIFI player Didn’t know what kind of feeling HIFI is? Accompanying my walkman many years ago have been idle, especially after using a smart phone, the player is rarely used. In recent years, some mobile phone manufacturers have launched so-called HIFI phones, which can personally be called HIFI phones. Not particularly agreeable, although I have not used HIFI equipment, I can still know the price of some well-known HIFI players and HIFI headphones, so those HIFI phones that have been advocating do not have a cold, may sound better than ordinary mobile phones, can really say HIFI phone, really some do not believe it.
The two letters L and R feel a little bigger and look a bit like two. To tell the truth, it has been a long time since I didn't know why headphones had to be divided. It took a long time to know the reason.
Headphone cable up to 1.2 meters, usually feel a bit long to the phone, but it is just good for the computer.
The connectors and buttons are also made of metal and they feel good.
The wire is very soft, not very thick, and I hope it is strong enough and durable.
The details can also feel better, like the interface and axis in the two images below can be done more beautiful, do not look so rough,
Meizu HD50 headphones used more than a dozen days, but unfortunately they did not grow gold headphones, a lot of things can not hear, just listened to one night after unpacking, after learning someone hot for three or four days headphones, more than 40 hours later Listening to the feelings and the sounds that were heard during the initial unpacking did not seem to be exactly the same, but they could not tell where they were different and felt more comfortable listening.
Meizu HD50's price is not high, Yan value is higher, at least worthy of this price, see forums and posted it there are many users ask Meizu HD50 value is not worth buying? In my opinion, in fact, there is nothing tangled about this issue. If you have a pair of gold ears, perhaps the HD50 has a place to win, but it really is not suitable for you, after all, a point price. For the average user, there is no better tangled, a 399 yuan headset from the current market, can only be considered an entry-level headset, after all, usually buy a headset, in addition to road goods, have to A few hundred dollars.
Because wearing glasses, so usually very little time to wear headphones, a long time pressure ear pain, Meizu HD50 also have this problem, although not very tight to wear, can wear a long time or a bit pressure on the ear, here to wear like yourself Eyeglasses friend wakes up.
Yuhai piezo materials include : hard piezo material, soft piezo material and lead free piezo material
Soft piezo material exhibits: larger piezoelectric constants, higher permittivity, larger dielectric constants, higher dielectric losses, larger electromechanical coupling factors, low mechanical quality factors, a lower coercive field, poor linearity, and is easier to depolarize. The ideal application of soft piezo materials is sensing needs. Yuhai soft pizeo materials are PZT-5, PZT-5H, PSnN-5 and PLiS-51.
Hard piezo material exhibits: smaller piezoelectric constants, lower permittivity, smaller dielectric constants, lower dielectric losses, smaller electromechanical coupling factors, high mechanical quality factors, a higher coercive field, better linearity, and is harder to depolarize. The ideal application of hard piezo materials is high power transducer needs. Yuhai hard pizeo materials are PZT-4, PZT-8, PCrN-4 and PBaS-4.
Yuhai company developped lead free piezo material BaTiO3 and apply for the Chinese Patent in 2011, to meet the needs of environmental protection in today's society.
