At the beginning of February 2012, A Sui's first product, the moving iron earphone AM90, was launched. This earphone with the Lou's balance armature moving iron speaker 168 yuan made everyone shocked for the first time, moving iron earplugs can be so cheap! Then there was the AS100, AS200HD headset. In the second half of 2012, the improved AS100 red line version and AS200 improved version were introduced for the opinions of the listeners. The moving iron also launched the AX7 of the double-action iron unit.
Shortly after the introduction of the AM900 in the dynamic earplugs, A Sicui introduced the AM800 in the wood alloy cavity, and the DX60 communication earplugs were only used in less than a few days. The new DX50 appeared in the official promotional materials.
The DX60 is a 13.5mm large unit earphone. Usually, the larger speaker unit can bring more powerful low-frequency performance. From the packaging, you can see that the DX60 has a special appearance. It looks flat and flat. The official design will be this. It is called a streamlined cavity structure.
Look at the parameters, the impedance is 16 ohms. It is easy to push earplugs, bandwidth: 20 Hz - 18000 Hz, sensitivity: 110 dB / 1mW (SPL at 1KHz) wire: 1.2 ± 0.3m PU special wire, it seems that there is nothing too strange in the parameters .
A Sicui comes with a patch cord, which is compatible with the two interface standards used in mobile phones on the market. Otherwise, the microphone will not work on some mobile phones. Currently, the mobile phone headset interface on the above has the national OMTP standard and the international CTIA standard, DX60. The earplug's own connector is the CTIA standard. The definition of the international CTIA standard is: left channel - right channel - ground line - microphone, iphone / Samsung, Huawei, Motorola, millet and other mobile phones use this standard national OMTP standard definition is: left channel - right channel - Microphone - Ground, Nokia, Sony, Lenovo ZTE use this standard.
The cavity of the DX60 is plastic, the process is relatively general, the plastic taste is very strong, but the shape design of the cavity is quite characteristic, but the aluminum alloy metal behind the case gives a lot of visual effects, and the above is etched. LOGO, this LOGO looks a bit like Sennheiser.
The inside of the outer casing cavity is curved and the cavity is flat. This has the advantage of being able to fit the ear when worn for better wearing comfort.
The DX60's wire-controlled microphone, the lower wire used by the DX60 is the popular "noodle line", but I think this width is a bit too wide, and the size of the earplug is very heavy compared to the size of the earplug.
The wire of the DX60 is relatively soft and is "bulletproof" (elastic), which is not easy to entangle. The remote control communication operation is simple, but it is controlled by one button. The basic operation is clicked to answer, and then click to hang up; relatively speaking, the operation of listening is relatively complicated. Press briefly for pause/playback switching, press twice for the next song, and quickly press three times for the previous song.
From this point of view, you can see the 3 holes on the DX60 cavity, one of which is closed because of the need for tuning. The tuning of the DX60 meets the needs of general music appreciation. At the same time, the voice call was optimized, and the voice was more prominent. From the sense of hearing:
1. The amount of bass is relatively large, so that the DX60 has a relatively large sound field, but the texture and volume of the bass are not very strong, the impact is not very strong, there is no thick feeling, the bass style is lighter and looser.
2. The medium frequency is good in density, but the high frequency is not bright enough. This is also to meet the needs of the call, so the style of the whole plug is partial.
3. The overall sense of hearing is because of the low volume, so the atmosphere is good. Listening to slow songs is not bad, such as R&B/JAZZ with low voice and low bass.
4. The tuning of the whole plug is obvious, the level and clarity are average, and the intermediate frequency and low frequency are relatively slightly confused.
From my personal sense of hearing, the DX60 is a good alternative to the original Earphones for outing the street and enjoying the music. Although the music quality is generally good, the clear guarantee of the call makes it have higher practicality, but the bass. The energy on the screen must be preferred by netizens who like to go out to listen to songs. The part of the middle and high frequency is more suitable for boys. In simple terms, POP is a suitable track for this earplug. I believe there are not too many netizens. What about symphony and piano music on the street?
Compared with Asilui's moving iron earplugs AM90 and AM800 with wood and alloy as the cavity material, the AM900 is much smaller than the two brothers, but this is a very praiseworthy earplug. It is my favorite style in the middle and high vocals. The packaging is the same as the AM90 in kraft paper packaging. It belongs to the product developed by Asi Cui in 2012, and the new packaging style is replaced with translucent.
First look at the parameters: drive unit: Ф 10mm bandwidth range: 8Hz-24000 Hz sensitivity: 106 dB / 1mw (SPL at 1KHz) impedance: 28 OHM rated power: 3 mW maximum power: 5mW, priced at 288 yuan.
From the unit size, the 1mm unit counts small-sized units in the in-ear earphones. The impedance of 28 ohms is higher than that of the general earplugs. The impedance of most in-ear earphones is about 16 ohms, and the sensitivity is not very high. index. From these three indicators, this headset has certain requirements for the transmitter thrust. The Bayer diaphragm used in the AM900 is also relatively low, because the small unit and high impedance mean that the diaphragm needs to be greatly moved. Greater thrust.
Generally, we think that high-resistance earplugs can obtain a relatively high-quality hearing sound compared with low-resistance earplugs, because high-resistance earplugs are relatively slow to react to clutter, and have low noise and interference sounds, but in fact, this is a double-edged sword, most of which is high. The details and resolution of the sound on the small thrust player and the dive of the bass are not sufficient.
Two sets of silicone sleeves and one set of blue low-return sponge sleeves are included, but this set of sponge sleeves feels more general and elastic, and comes with an earplug storage box.
Appearance, AM900 is a very simple modernist design style, the shape is not special, but the use of silver metal material makes the earplugs look very textured, AM900 has a shell blue, I think it is More beautiful.
The AM90 also has a feature that the cavity is relatively small and the overall design is relatively short, which makes it easier to wear, and the shorter cavity design can be worn in bed to listen to songs.
AM900 uses the same wire as Am90, transparent gold and silver wire, the wire is soft, and the elasticity is relatively strong, not easy to entangle, but the stethoscope effect is quite obvious, Aspiri can actually consider attaching a small clip, which will greatly reduce This problem is a problem for customers.
The sound of AM900 is the same as that of its outer metal casing. It is slightly hard. I can basically use the F805 to launch a relatively decent sound, but I still feel that the degree of diaphragm movement has not reached the limit. If the amp is added, it may be There will be a certain degree of improvement in the sound. In terms of listening, the AM900 is a small warm earplug with a relatively small amount of bass. The performance of the mid-range vocals is quite good.
1. Although the amount of bass is relatively small, the layering is elastic. If you listen to a piece of music such as rock, the impact of the bass will be weaker.
2. The high-pitched part is relatively bright, but the high-pitched sound is not sharp, and the tooth sound is very small, so the AM900 gives you a high-pitched sound that looks smoother.
3. The mid-range part of the AM900 sound is my favorite, the density is good, full but not exaggerated, and the high-pitched sound has a small fresh feeling.
4. As far as I can see, AM900's sound is a kind of earplugs that are less comfortable in natural, high-pitched and bass. Some people think that such earplugs are relatively dull, but I think AM900 is very suitable for listening to human voices. A natural style that is not exaggerated is loyal to the original sound.
Wearing the blue sponge cover AM900, from my personal feeling, this earplug listens to the Japanese healing system female voice will be very comfortable, AM900 is a small fresh feeling, the European and American voice is also very suitable for male love songs, gentle and pleasant The performance of the big dynamic music will be a bit cramped, because the performance on the sound field is also relatively small, giving the overall feeling of the atmosphere is not enough.
AM800 is the star product of 2012, because there are not many domestic earplugs using wood and metal as the cavity, and the sound performance of AM800 can indeed be called the star in domestic earplugs. The price is 298 yuan.
The parameters are no longer listed one by one. Compared with the AM900 of the same door, the biggest difference is that the impedance of the AM900 is relatively small. The AM900 is 28 ohms, the AM800 is 16 ohms, the bass response is 27 kHz for AM800, and the AM900 is 24 kHz. Simple. From the parameter point of view, we can understand that the AM800 is easier to push, and the response and dive of the sound is more obvious than the Am900.
A set of red sponge sleeves is included in the package, and the texture is much better than the blue sleeve number of the AM900. There are also two sets of gray silicone sleeves, one of which is hidden in the velvet bag.
The combination of wood and metal is the biggest highlight of the AM800 design. The texture of the metal brushed and the texture of the wood collide together, giving a good feeling. The sense of the line of the cavity gives a feeling of retro. This is a design aesthetic. Very good earplugs, light from the appearance of people have the desire to have it.
The cavity of the AM800 is not large, but the silicone sleeve is very large. Thanks to its 1mm unit, it is also light and comfortable to wear. I think the earplug is the same as its appearance. Earplugs that are both soft and soft and have high energy and low energy.
The wood cavity of AM800 is loyal to the original color and texture of wood. My picture is darker because of the light. The main thing is the varnish, the color is lighter, the texture of each earplug is different, and it is the only one. You remember to pick the texture you like.
Take off the silicone sleeve on the catheter and you can see some details. The work of AM800 is very elegant. From this picture, we can get more information: the filter screen of the catheter is very dense, the venting hole and the metal surface of the catheter are AM800. It is plated black so that it forms a color difference with the silver-gray outer shell. The metal cut surface of the outer shell is very smooth, and the edges are carefully treated to avoid cutting the user's fingers. This cut surface forms a glittering ring and an iron triangle. Like the CKS series of high-end earbuds, it reflects white light in rainbow colors.
The work of the plug and the Y-shaped branch is very good. It is coated with a metal material. The wire used in the AM800 is translucent. You can see the silver envelope inside. This line is hard, so it is not easy. Winding, but be careful to avoid breaking.
With the AM800 with a red sponge cover, the retro look suddenly jumps out of the sultry feeling. The first ear of the AM800 sound will make you more impressed.
1. The amount of low frequency is not a lot, but it is more than AM900, the dive is quite good, it seems more flexible, but from the performance of the overall sound field, AM800 is also a small sound field earplugs.
2. The sound of medium and high frequency is brighter, the intermediate frequency is fuller, the vocals are closer, and the high frequency is very bright.
3. AM800 is a relatively obvious earplug in the middle and high frequency rendering, which enhances the penetrating feeling. The sound image of the earplugs renders a clean and prominent mid-high pitch. The penetration and stimulation are obvious, and there is a female poisonous tuning. Tooth sound, but not much, not as extreme as the iron triangle, the overall atmosphere is good.
4. From the scope of the audition, it is a relatively wide earplug, the middle and high vocals have a good performance, and both the music and the classical can have a good performance, which is very cost-effective.
The price of AM800 and AM900 is similar. The price of AM800 is 298 yuan, and the price of AM900 is 288 yuan. The gap is very small. This has caused us to choose the trouble. Today, this post was also written because of the group’s group and Weibo. There are more discussions in the audience. What is the difference between the sounds of these two earplugs? We will discuss some of the following, personal opinions are for reference only.
1. From the sound field, analysis, the amount of bass, AM800 dominates
My personal listening experience is that AM800's mid-high frequency is brighter than AM900, and the sound that can be heard is higher in the analysis. The amount of bass can be more on the AM800, so the sound field is much larger than the Am900. .
2.AM800 separation and atmosphere more
The AM800's music and vocals are very open, and the overtones on the bass also make the overall sense of the earphones feel full, and the type of listening music is relatively light.
3. AM900's treble is more quality, rendering is not heavy
For me personally, I don't think the AM800 is better than the AM900. If you carefully distinguish the difference between the two, you will find that the AM900 is harder than the AM800 in high notes, especially the music. The AM800 music is To be slightly Microsoft's AM900, the AM800 enhances the penetration and spatial sense of the mid-highs on the tuning, creating a feeling that the player suddenly turns on the WOW surround sound, and the sound is lingering. In fact, this will make the sound of different frequencies. Interference occurs, the middle and high notes are crosstalk and the taste is more obvious, and it looks more ethereal and ethereal. The sound of AM800 seems to be flat, the performance on the high sound is very prominent, the middle sound is very natural, there is not much reinforcement, and it will not be too high to perform the high-pitched performance. From this point, I think AM900 is in the middle and high-pitched voice. The quality is better than AM800.
4.AM900 sound is not unassuming, not exciting, is a natural and gentle style
The sound of the AM900 as a human voice is a kind of plain and natural style. I feel that it is more rare than the rendered sound that has a penetrating sensation. However, this style may not be enough for the general user. This kind of tuning style is compared. Picking the type of track, but also picking its user level, this kind of interference is less, rendering less vocal performance, in fact, is the quality that fans love, but maybe the average user may feel this earplug if there is no better player. Usually.
At this price point, AM800 is undoubtedly a very cost-effective earplug, omnivorous property, control of POP is handy. The appearance of the coquettish and the appealing sense of hearing will also please the majority of users, which is very suitable for beginners. And if you really want to add a natural earplug for your voice, AM900 is my recommendation.
