First of all, I would like to thank the audience for allowing me to have the chance to test my own knowledge of HIFI audio. Although the value is not very high, it is not Xiao Cui's flagship product. I am also acquainted with Astrid. In accordance with the principle of sharing, individuals are still very serious.
Asi Tsui many fans called it Xiaocui, Xiao Chui's former customer service was called Xiao Bing, likes to ride, wrote an earphone copy called a small steel gun, the name and color of the earplug Leiren, leading to At last it did not get fired. Of course, the soldier also left. Xiao Cui's product or from the AS100 headset to start with, the value is also one or two hundred, then the sound quality can but work like a general, then Xiao Cui launched a dual-action iron AX7 and other products, involved in the mid-market, The product is also tepid. Afterwards, Astrid dominated the low-end market, taking the low-cost iron as its breakthrough point. The main models of the Asicsi AX35 and AX30 were headed to another domestic-made headphone brand, namely Dasheng Branch, which resulted in the Dainhenko DN900 also not firing. All this can be described as a loss of both sides. Then Xiao Cui introduced the high-end ring iron AX60 and flat head plug LYRA6, although there is no big purple but it also harvested a certain number of fans.
The packaging of the AM850 is still improved, and it is much more advanced than Koizumi's previous aesthetic.
After opening up and touching the AM850, the packaging is still very textured. Hi-Res certification in the lower right corner of the bad street, are SONY with bad, and now basically do not wear small gold standard are embarrassed to say that they are HIFI headphones, in short, Hi-Res certification is now able to print money.
Printed on the back of some earplugs the most useless parameters, which have a certain reference value and the CPU parameters, earplugs parameters can not be determined.
Side of the security signs:
An anti-counterfeit logo is written in capital letters, and Astrid's fakes are still very rare. On the counterfeit goods, Senhai and Monster are the hardest hit areas.
A cover under the armpit, this one is very texture.
After opening is a warranty card, the design is somewhat small and unique.
After winning the warranty card, you still can't see the true colors of the book. There is a section of paper that introduces the Asicstek LOGO.
Remove the paper and you can see the AM850 earplugs and the iron earbud cover fixing plate.
AM850 metal earbud cover fixing plate texture is still good, the middle of the M number has been installed on the ear plug body, and in the OSTRY Austrian sharp KC08 I have seen this design, iron plate sets can still increase the product forcing.
The appearance of the AM850 uses a metal case, which is also very common.
Koizumi's accessories are still very rich. There are similar headphone storage bags, iron plate sets, aircraft plugs, and a variety of different sizes of earplug sleeves and ear hooks. First of all, Zhang's official accessories introduction map is more intuitive.
The brown earplug storage bag is printed with Astrid's LOGO. This small bag is also good for wallets.
Iron plate sets and aircraft plugs, aircraft plugs can be used to plug in aircraft, but the music provided on the aircraft is estimated that many people are not accustomed to.
There are a number of ear hooks and sponge covers, and there is a tendency to go straight to the plant.
The appearance of the earbuds of the AM850 is still very good. The outer shell is made of aluminum alloy. The end of the cavity is a novel place where the red sandalwood of Côte d'Ivoire is used. This design can reduce the secondary reflection at extremely high frequencies. Côte d’Ivoire rosewood is still the first to hear, but it does have some impressions of Warcraft Drogba.
Ear plugs are L-shaped and look like SONY style.
AM850 unit shell metal material is still very obvious, the pressure of wearing is not very strong.
AM850 is marked with LR left and right signs at the sound outlet of the unit shell.
The AM850's earbuds end of rosewood, this design is still very novel.
The use of silver-plated wire on the wire, in theory, better resolution and clarity.
Driven:
Koizumi AM850 as a dynamic earbuds, only 16 ohm impedance, very easy to drive. Whether HIFIMAN's supermini or iPhone6S mobile phones can easily navigate, Am850 positioning is also taking into account the mobile phone users, so the thrust requirements are not very high.
With sense of hearing:
The SuperMini with the AM850 is a lean, skinny style with a slightly more sense of hearing and a more balanced three-frequency band. The sense of low frequency is neither significant nor prominent. The low-frequency details are partly missing. The resolving power in the low-frequency part is slightly inadequate. The high-frequency band has dyeing modifications. The sweetness of some Japanese headphones is more like that of the current mainstream stream. Analog taste.
D50 with AM850 sound is a combination of quality and sense of hearing, the two are half, low frequency has a certain amount of sense, but it will not be fully covered by other frequency bands, high-frequency brightness is full, but not too loud, keep Some polishes, this is the sound of AM850's own voice and D50's dry hard tone.
HM901 with AM850, in the sense of hearing and quality tend to listen to more sense, because the HM901 and AM850 style are somewhat similar, are biased towards simulated taste, low-frequency sound dye, lack of sense of full amount of loose sense, IF thickness is enough, people The sound is also very full, giving a warm feeling, high-frequency brightness quite satisfactory, but it is very compliant and resistant. The sound field is relatively open and can respond to most music.
Overall sound:
Tri-band: The AM850's tri-band is more biased toward mid-high frequencies, and the sound style has a partial listening feeling. It belongs to users who are more inclined to pay attention to taste, and the overall sound is loose and warm and soft.
High frequency: The AM850's high frequency also has obvious staining, the advantage is not harsh, the disadvantage is not transparent, and the details of the performance is not very rich, the performance of the performance is less.
IF: AM850's IF is nearer to the listener. In the vocal repertoire, AM850's vocals will be very prominent. This is somewhat similar to ER4B. And the vocals were slightly thicker, with some modifications and dyeings, and some Japanese girls' styles gave a lingering sensation.
Low frequency: AM850's low frequency is not particularly manifested itself, the low frequency volume sense will not highlight itself when the instrument is too much, and the low frequency performance also some shrink is not very open, for the low frequency control, the AM850's low frequency will not be particularly exciting .
Sound Field: The sound field of the AM850 is sufficient for most popular styles, and it is somewhat difficult for the classical.
advantage:
Good workmanship, rich accessories
Sound listening, simulated taste
Disadvantages:
Single sound style
Low-frequency control, quality streaming users may not be suitable
