Astrotec AM850 HI-RES Certified High Definition HIFI Mobile Phone Music Headphone In-ear Gun Color 666 yuan Jingdong direct link Reasons to purchase HIFI headphones have always been a thing in my heart. I heard that fungus can also be cultivated, so I wanted to cultivate my own ears. Looked too much on the Internet evaluation and recommendation, found that headphones and lenses, are a penny and a cargo, very money two points of the goods, since the initial burn, it will do what it takes, set yourself about 500 The budget.
Usually listen to popular, more vocal, do not like to carry too much equipment, for the time being without the intention of the player, mobile phone direct push is the best, iPhone 7 is not 3.5mm interface, op amp is built in the switch cable, Will inevitably enter an external op amp, choose to choose to go, choose this new Astrophe am850 headphones.
Thanks to the good reputation of am800 on the one hand, the phone pushed straight.
On the other hand is the appearance, the problem is that each one gets into the eyes, I like the shape of the am850. The alternative was the iron triangle im70, do not like the red, Weisoni can GR07 shape slightly worse, and I heard that quality control in general, titan5 shape and reputation is also good, but in the end was still selected in the friend's recommendation Astrid new This am850.
Unboxing is as follows: ~~~~~~~~~~~~~~~~~~~~~~~~ There is no over-environment, nor too much praise, though I do like it. Basically restores its own texture. Please don’t say I’m too beautiful. As a Weibo Certified Mobile Phone Photographer, the following photos are all shot by iPhone7 P.
The box has a girdle like a book, and the Hi-Res certification is very conspicuous. The specifications for the three languages ​​in the English, Chinese and Japanese languages, and the bar code and serial number are on the girdle.
Anti-counterfeit labels I did not open, because Aspen Tsui each headset has a separate code, you can scan the two-dimensional code concerned about the Aspen Tsui WeChat public number for self-sale.
Now the headset box is so tall.
Open the rear headphone body and three models of silicone sleeves. The silicone sleeve is fixed in a metal plate.
The number of the headset is printed on the plug. My number is 02280
The tail of the cavity is the wooden part of the am series, sandalwood. Compared with the previous generation of am800, the wood part has been significantly reduced. I would like to take it apart and see how large the sandalwood cavity, which is known to reduce secondary refraction and reduce resonance, is inside.
The leather headphone bag is a bit thin, has poor compression resistance, and has limited protection for the headphones. It may be that the metal cavity is not afraid of pressure.
The signs of the left and right channels are hidden, usually blocked by rubber sleeves. Each time you wear headphones, you have to look specifically to see.
The metal brushed cavity, the red of the connection line and the red echo of the sandalwood
Metal mesh
Silver-plated core, the outer rubber feels astringent, looks very thick, in fact, very thin. The elastic foot of the thread is easy to wind.
The adapter used on the plane is included. This is of little use. The am850 model is printed on the line.
Accessories family portrait, in addition to three pairs of silicone sleeves, there are three pairs of color brother sets, a pair of sponge sets. Earhook is also silicone material.
The rubber sleeve is very easy to get rid of dust, it is not easy to wipe clean, and after shooting, it is so clean. The color temperature of the photo shoot is still quite accurate, and the basic restoration of the texture is not excessively beautifying.
The shape is my favorite type, metal cavity texture is very good, do not know the part of sandalwood, playing on hand for a period of time can not be pulp? Haha. Can not say too much, or Xiaobian should say I have too many words.
Headphones are very comfortable to wear, ear hanging soft, will not card ears, but this kind of external ear hook is easier to fall off, once listening to the song halfway off the headset to answer the phone a little off, not as iron triangle im70, combined with the wire together.
Because it is a direct push of the mobile phone, I did not audition loss, but the NetEase cloud music 320K MP3. In theory, my fungus should be enough, huh, huh. The am850 is Hi-Res certified and may be specially tuned for headphones. It is suitable for mobile phones. It feels warmer, especially in terms of vocals, the sound is very clear, suitable for popular, especially female. The symphony of the multi-instrument is slightly poorer, the degree of separation is normal, and the bass is not heavy enough after diving down. Many more metaphysical descriptions will be described after I have taken the opportunity. It is really a bit poor.
Having said that, of course, what I bought for myself was something I liked. I have been very restrained and tried my best to pick it up.
to sum upAdvantages: Good-looking appearance, balanced three-frequency sound, suitable for female voice. Other advantages are being explored.
Disadvantages: Compared to the previous generation, the wooden part is too little. The low frequency is a bit weaker, and the intensity is enough, but it's a bit muddy, especially listening to rock. Headphone cable feels astringent and easy to twist.
The price of 666 yuan is very interesting, personally feel a bit expensive.
Aviation headphones are used in airplanes, cars, subways, etc., to facilitate passengers to listen to audio and watch videos to enjoy a pleasant journey.
The aviation earphones are mostly disposable, so the structure is extremely simple, the shape is relatively ordinary, the materials are small, and the annual usage is very large. The number of inquiry can reach several million or even tens of millions, so the cost is very cheap. earphones can cost as little as 10-15 cents. Therefore, they are disposed of as garbage after used, and passengers could take it away for personal use.
Styles can be divided into on ear headphones and in ear earphones.
Functional difference: power, impedance, and sensitivity etc. are also different. Airplane Headphone is mainly customized according to the equipment, place and user used. For example, 1 customer might require 300 ohms impedances , and other customers may need 32 ohms. For adults, the sensitivity may reach 100DB or more.To children, the sensitivity may be around 85-90 DB.
In addition, aviation headphones are not all disposable ones. Some first-class cabins need to be equipped with headphones with good noise reduction, sound quality and functions. So the price will be much more expensive.
