AX35 is a "circular iron" earphone launched by Astrotec, a headphone brand in Shenzhen, China. It uses a moving iron unit for high-pitched sound and a 10mm diameter moving coil unit for low-frequency, and the headset is priced at 399 yuan. Among enthusiasts, it is a well-known ring iron earphone product, which is also a relatively low price in the dynamic ring + moving iron configuration. It is also because of these factors that we purchased this product. How is it performing?
Starting from AKG K3003, the design method of the combination of moving iron unit and moving coil unit is more and more in small earplug products. Although Soomal has not released the evaluation of K3003, there is also a downtime in the hands. Plus us The evaluated SONY H3, Dynaco DN-2000, etc. also have a certain understanding of the current price of the ring iron headphones. In general, the so-called circle iron is the progress of the moving iron tweeter with the help of nearly 2-3 years. In the in-ear earphone products to enhance its high-frequency performance, after all, the high-frequency dynamic unit can exceed the GR07 MKII, SONY EX1000 we have not heard, and the high-frequency performance of the high-end moving iron unit It is obviously more than them.
Of course, why not just make a multi-unit moving iron earphone, the low frequency also uses the moving circle? The explanation of the ring iron earphone is to have the low-frequency slack in the moving circle. But from SONY H3, DN-2000, even K3003, we have not It is found that the dynamic low frequency is better than the low frequency of the high-speed moving iron headphones. We have long argued that although the moving coil can provide a relatively loose intermediate frequency and low frequency, the more important reason is that the high quality multi-unit moving iron is very high. The cost of using "high" is not an exaggeration.
We returned to the Axe AX35, this headset for 399 yuan, it is obviously impossible to use the best high-pitched moving iron unit, and the cost of the moving coil unit is not absolute. Since it is planned to launch "circle iron" headphones Two elements in one earplug will test the designer's level. Can the harmony of the two unit sounds be harmonious, and the natural connection will finally show a kind of sound style? From the previous design of the circle iron, The difference in sound style is also quite big.
There is no further information on the internal structure of the AX35. But back to the appearance of the AX35, it is very good. The AX35 uses an all-metal earphone casing, regardless of the shape of the headphones, the cutting precision and process of the corners, and the oxidation of the surface. The craftsmanship and texture are very good. Compared with the Dynaco, which likes to use the metal casing, the AX35 has a higher level of appearance. Overall, this is a small earplug that is more beautiful at 399 yuan.
The official AX35 indicator shows that it is a very low-impedance, high-sensitivity earphone. The 12-ohm impedance and the sensitivity of 104dB are indeed an easy-to-drive earplug. Since the sensitivity unit is taken from the sound intensity at 1kHz/1mW, The frequency of 1 kHz is actually emitted by the moving coil unit inside the earphone, so its high frequency theory may be easier to drive some? Or, in the design, some matching of the impedance characteristics of the two elements should be done.
A Citri AX35 this headset is very early when we bought it. It has been down for a long time. The downtime is very long. It should be about 800 hours. The change of the overall sound performance caused by the headset is not particularly large. According to it The style of the sound, the main reference for the evaluation today is the innovative Aurvana In-Ear2. This headset has not appeared for a long time. In addition, it will also briefly talk about the style of the K3003. The audio source used includes the iPhone 6 Plus and the vivo X5 Max. Main mobile phone platform, Fei Ao X1, X5, Lotto PawGold player, etc.
Overall impression: The overall style of the Axe AX35 is relatively neutral, the sound is slightly tight, and the high-frequency unit definitely cannot reach the level of the moving iron treble on the W4R and UE900, but if it is not said that the AX35 is a ring iron earphone, it is also fundamental. I don't think it is a ring iron earphone. Its high frequency style is very peaceful. If you have heard of Sony's XBA-H3 or Dynaco's DN-2000, you know that the high frequency of the ring iron is very arrogant. It seems that In the very exaggerated show off its high-frequency superior quality. And AKG K3003 is actually not a style such as DN-2000, H3, is also relatively peaceful.
High-frequency performance : In the existing high-end headphones, the moving iron unit of the company's moving iron unit brings the high-frequency overall performance improvement, which is the biggest advantage of the moving iron earphone relative to the dynamic ring earphone, and is also the most important link of the ring iron design. Unfortunately, The high-end moving iron unit is costly, and the high-frequency unit of the AX35 is far below this level. We use the innovative In-ear2 as a reference because the AX35's high-frequency and medium-high frequency overall style is very similar to it. The high frequency of the AX35 is relatively restrained. Although it is a moving iron unit, although it has no top level, it has at least reached the same level as the moving iron unit of the In-ear2 period. The sound has no obvious metallic taste and has a good sound density and resolution. The big dynamic performance will not be as burring as the entry-level moving coil, and of course the sound is not stretched enough. [Note: The innovative Aurvana In-ear2 is the iconic technology product that we think is the new generation of moving iron headphones around 2010. The earphones used are one moving iron unit.]
On the ordinary sound source of the iPhone level, the high frequency of the AX35 is also stable, the resolution is good, the middle and high frequency parts are slightly restrained, and the sound field performance is relatively average. What I did not expect is that the sound performance of In-ear2 on the entry level sound source. It is more stretchy and softer than the AX35, and it seems more calm under the big dynamics. To change to the better X5 Max or FIIO X5 player, the AX35's high-frequency to very high-frequency part has the advantage of extension, this part of the resolution And transient, AX35 is slightly better than In-ear2. Overall, AX35's high-frequency performance is relatively calm, stable, clean sound, and has good control. The shortcoming is that the high-frequency part begins to appear conscientious and not stretched. This also caused a certain degree of disconnection between it and the intermediate frequency.
IF performance : The AX35's IF performance is relatively unsatisfactory. This has been shown in the mid-high frequency. Compared with the single-unit In-ear2, the AX35 shows signs of disjointed between the mid-frequency and high-frequency parts. This disconnect is not The high frequency pull-up caused by the dynamic style is inconsistent, which may be caused by the limitation of tuning. Its intermediate frequency is still relatively restrained and relatively soft, but the sound can not be opened, and the performance of vocals is also obviously compared. Restricted, part of the vocal high-pitched area has obvious squeezing feeling, which also makes it lose a lot of explosive power and a certain three-dimensional image. In Inear2, it will suddenly feel that the sound dynamic has obvious advantages, and the sound is open. Some, the performance of the IF is also a lot natural. I have to say that in the vocal part, whether it is the moving iron such as In-ear2, or the AX35 circle iron, the resolution performance is not as good as the pure dynamic headphones. For example, Vsonic GR07 series, VSD3 series, etc. Therefore, the AX35, In-ear2 level of "moving iron" advantage is still in the high frequency, the intermediate frequency part has actually begun to deteriorate. Turning back to say, this part of K3003 is quite good.
Low frequency performance : The low frequency of AX35 is relatively difficult to control [relative high frequency and intermediate frequency]. Under the iPhone, it will appear that there is a little bit of low frequency, and some of the dynamics are slightly uncontrollable. However, in X5 Max or The FIIO X1 player or better sound source will be significantly improved, the overall still maintains a more balanced sound style, but there is no advantage of the dynamic headphones in the low frequency. The AX35's low frequency is still neutral, no heavy taste tuning But unfortunately, there is no very good transient and resolving power. It can only be said that it is in line with the universal level of the entry-flow headphones. The AX35 sounds very much like the Aurvana In-ear2 single-action iron. The low frequency of the unit headphones, the sound is not detailed enough, and not enough stretch.
to sum up
The overall performance of the Axe AX35 is more like the performance of an entry-level moving iron headset. Its performance is somewhat similar to that of the innovative Aurvana In-ear2, but the increased dynamic unit does not bring more positive effects. Compared with In-ear2, from the middle to high frequency to the low frequency, the AX35 sounds more restrained and the details are relatively worse [compared to In-ear2], the dynamic is also significantly weaker, if you use the AX35 moving iron unit to directly operate Iron headphones, is there a better result? Because In-ear2 is such a single unit of moving iron headphones.
K3003's high price and circle iron concept make many people think that this is a good market selling point, but from the K3003 itself, its overall strength can not compete with the current multi-unit moving iron headphones at the same price. The level of the moving iron unit is indeed constantly Progress is a very big technical advantage for small earplugs. However, the combination of "circle iron" is more about the concept of marketization and productization. Using the moving coil unit to reduce costs, you can also get one. "Circle Iron" looks like a high-end reputation. Overall, we think the AX35's performance is slightly weaker than Aurvana In-ear2, only the high-frequency extension resolution is slightly better than In-ear2. Its overall style and level The price of 399 yuan basically matches, but let us doubt that the entry-level headphones can find high-quality and high-quality sound on the "circle". The AX35's audition and evaluation also let us reduce the "circle" headphones again. Sub-". Later, we will continue to pay attention to SONY's latest XBA series ring iron headphones.
