In March 2014, Dynaco released a new generation of "Circle Iron" headphones DN-2000. According to official data, this headset is positioned above the previous generation DN-1000, and Dynaco also has DN-2000. The sound quality seems more confident. With the high-frequency advantage of the company's moving iron unit, coupled with the influence of the AKG K3003 sky-high "circle iron" headphones, this moving coil + moving iron multi-unit in-ear headphones are also In the high-end in-ear headphones, it has become a new thing. What is the performance of DN-2000 in the accumulation of DN-1000 technology? Thanks to "Forever still" users to provide test samples.

Just after the small holiday in early April, it is said that Forever is still excited by the netizen to win the Dinko DN-2000. From the picture, the serial number of this earphone is 00047, indicating that it is a very early batch, again Thanks for the strong support of my friends. The small design of the serial number is also my first impression of the DN-2000 headset. For the enthusiast users, these small details seem to be a good embellishment and packaging for the product.

Closer to home, DN-2000's predecessor DN-1000, I don't know why, Soomal just didn't hear it at all. Unfortunately, today can't be used as a reference. In the DN-2000 network promotion, many online stores and media. Willing to compare the DN-2000 with the K3003, it is precisely because of the K3003's extremely high price and "circle iron" design.

The DN-2000 uses a two-tone high-speed moving iron speaker from the company to match the design of a bass dynamic speaker unit [Official Information], which is the reason for the so-called "circle iron" name. Many enthusiasts know this 娄The company's unit is widely used in W4R, UE900 and other headphones [not completely determined, model Knowles TWFK-30017-0000]. Due to the high price role of K3003 role [Soomal heard K3003, I feel not very good], but also because of The quality and plasticity of the company's tweeters [we can hear the obvious difference in the style of this unit on different headphones] is really outstanding, so the circle seems to be becoming more and more popular.

Why use a combination of dynamic and moving iron? In addition to the role of marketing, we currently have no objective data to prove the advantages of this design. From the experience of Soomal evaluation, for in-ear earphones, currently This moving iron unit performs better than the existing moving coil unit. It not only has high frequency, but also has certain advantages in medium and high frequency. Although the cost is high, everyone is still willing to use it; and this unit does need to match a medium and low frequency. The speaker makes up for its lack of frequency in this part of the frequency band. Is it better to use the moving coil than the moving iron? Is it possible to ensure a good connection under the moving coil and the moving iron multi-unit? Will the crossover process encounter problems? At present, only the subjective sense of hearing can be compared and judged in the evaluation.

About the THzK-30017-0000 speaker, it is used by many headphones. The headphones we have tested include the Westone 4R, the Logitech UE900, and even the Vsonic VC1000 [without woofer]. Their sound performance is actually different. Big, this has a lot to do with the earphone design tuning. It is not the use of this unit, there will be a certain sound style and the same level. About this unit and the knowledge of the ring iron, moving iron speaker technology, we Like everyone else, we need to continue to learn further and have the opportunity to share it with you.

We will return the topic to the DN-2000 earphone itself. The DN-2000 uses an aluminum casing and weighs 22 grams, compared with the 2012 Soomal DN-13 and DN-11 titanium casings. The weight of the earphones is quite the same, but the appearance and center of gravity of the DN-2000 seems to have DN-11 [26 grams]. It is slightly more attractive when worn. It is not so obvious. The earphones use the most popular local gold color, and the earphone edges are also used. The chamfer cutting process like the iPhone 5. The advantage is that the appearance is really beautiful, the disadvantage is the same as the iPhone 5, this chamfer is fragile, it is easy to leave the scar after the bump. Everyone can only use the storage to avoid the bruise. .

For better wearing comfort, the DN-2000 has a small "device" on the side rear that can be used to mount "eye flaps" of different styles and sizes. The miniature ear flaps can be used with the right size. The concave contact of the outer ear of the human ear increases the wearing stability. In theory, it may improve the wearing comfort and effectively reduce the stethoscope effect. The ear wing design also allows the DN-2000 to change the left and right channels without changing the headphone cable. It can be worn around the ear or under the ear. Of course, DN-2000 also provides a wide range of earplugs of different material sizes for different users.

Perhaps everyone has noticed the three-color metal tuning ring in the DN-2000 accessory. The tuning ring is installed before the rubber plug in the ear part, that is, the depth of the rubber plug installed on the catheter. The size of the tuning ring is 1.2mm, 1.5mm and 2mm. Of course, you can also use it. That is to say, the tuning ring escapes into the earphone tube, and the rubber plug will be padded to the corresponding thickness. The volume inside the rubber stopper changes. Personally, because the size of the earplugs and the tightness of the earphones themselves have a great influence on the sound, the difference brought by the tuning ring is not too big, and the sleeve is not very tight and is relatively easy to lose, such as us. It has been lost. When testing, we are subject to the blue circle.

DN-2000 officially gives a headphone impedance of 16 ohms and a sensitivity of 102dB. It is a low-impedance but low-sensitivity earphone. Considering the sensitivity index is a standard parameter at 1kHz, the characteristics of different frequency bands of the headphones are not the same. In terms of actual hearing, the sensitivity of DN-2000 at high frequencies is probably very high. No matter what player, with DN-2000, you can easily hear some slight noise, which is more obvious than most headphones. Quite a lot.

In order to better evaluate this headset, we have over 500 hours of headset downtime, and the sound changes caused by the downtime are not particularly obvious, especially in the mid-high frequency part. The test comparison headphones include the Westone 4R, UE900, etc. we often use. Test source Use the Fei Ao X5 player [the combination recommended by Da Yike and Fei Ao], HiFiMAN HM-901 [Minibox amp card] and Le Bang Monitor 06 MX. At the same time use iPhone 5s, vivo Xplay3s and other mobile phones as a reference for common portable audio sources.

Overall impression : When using the DN-2000 for the first time, it just used a pair of medium rubber stoppers. For me personally, this size is somewhat small, but the resolution of the DN-2000 high-frequency part has been impressive. During the downtime, I chose a pair of the best rubber stoppers. [Oddly, this large rubber stopper is actually quite large...], the overall performance of the DN-2000 has become balanced, and the vocal performance is also higher than that of the moving iron. Headphones, including SE535, W4R, UM30 Pro, etc., appear soft and delicate. The low frequency is not too different from these using the moving iron woofer headphones, at least there is no obvious quality advantage, for different players and audio sources. More sensitive.

High-frequency performance : The high-frequency resolution of the DN-2000 is indeed not disappointing, and Dynaco's style of tuning the DN-2000 tweeter is relatively bright. Compared with the Logitech UE900, they are extremely The high-frequency extension is very similar, it is obviously brighter than the W4R, it is also lighter, and the details are rich. It is more calm and meticulous in the small and medium volume, and the transient performance is very good, compared with the high frequency of GR07 MKII. The advantage is obvious. Compared with the UE900, the sound of the DN-2000 in the middle and high frequency part seems to be slightly higher, which is brighter in some high-frequency recordings, such as pop music with poor recording quality, and explosive electronic music. Or the scent of the mouth is very heavy, the DN-2000 will have a slight burr, which is similar to the Vsonic VC1000, but not as exaggerated as the VC1000. This also makes the DN-2000's high frequency seem not so good to serve [compared W4R, even UE900 is the same].

When the DN-2000 is equipped with the Flying Pride X5, the high frequency of the X5 has obvious obvious traces. The high frequency of the DN-2000 is indeed more intense on the X5. Some very fast transient performances will be more enjoyable, extremely high frequency. The resolving power seems to be a little better. But on the X5, DN-2000 will appear to be high-frequency in many music, and X5 is difficult to control it under large dynamics. DN-2000 is in the middle and small volume. X5 may be more enjoyable, but the control is relatively general. In Monitor 06 MX or HM-901 or even Xplay 3s, the high frequency is not obviously modified, the warmer sound source, DN-2000 is more balanced, very similar to UE900.

IF performance : DN-2000's intermediate frequency began to show a clear difference from the pure three-unit, four-unit moving iron headphones, the sound began to soften, and the dynamic performance is not the same in different areas of the intermediate frequency. Perhaps in the moving iron headphones SE535 The IF comparison is more relaxed, and the vocals are much better than the neutral W4R [because the UE900's IF is really wide, no comparison]. While the DN-2000 is performing vocals, it seems to be much softer than the SE535, dynamic The upper part is worse than the SE535. The W4R IF is a relatively flat style. The dynamics in the middle and high frequency are also weaker than the DN-2000. The vocal image of the DN-2000 is not as clear as the SE535, UM30 or W4R, but The sound is more relaxed and stretched, and the female voice shows a significantly better resolution.

In the slightly lower part of the intermediate frequency, the dynamics of the DN-2000 are somewhat worse, and the sound is slightly loose. For example, the performance of the male voice is far worse than the W4R or SE535, UM30. The sound is still a stretch style, but it seems Insufficient strength. At this time, very good sound source driving force is needed. For example, the sound source at the X5 or Xplay3s level is obviously insufficiently dynamic, and there is a very good performance on the Monitor 06 MX. The advantage of the resolution is relatively obvious. In the big dynamic music such as symphony, W4R, SE535 and other moving iron headphones have obvious advantages in sound level and control. Although the DN-2000 IF is low, some sounds are still slack, and some sound fields are more relaxed, but Transient deterioration, sound level in general. W4R and other pure moving iron headphones in the symphony, a very dynamic level of clean sound is not DN-2000 can do. Of course, this is also relatively speaking, DN-2000 this The performance is also very good, but it seems that mobile phone-level audio sources should not be considered in the big dynamic.

Low-frequency performance: The low-frequency performance of the DN-2000 is not much different. Compared with the W4R, the DN-2000 has a lower sense of low-frequency. Compared with the SE535, it seems to have a smaller amount of sensitivity. The low-frequency elasticity of the SE535 or UM30 Pro. The performance of the big dynamics is not quite the same as that of the DN-2000. The DN-2000 dive seems to be deeper, but the sound is more slack; the slow-paced low-frequency DN-2000 has better details, while the more dynamic low-frequency, moving The performance of iron is obviously cleaner, but the elasticity seems to be more artificial. The low frequency performance of DN-2000 is also better under Monitor 06 MX or HM-901, and the low frequency dynamic performance of X5 is more general.

to sum up

The sound style of Dynaco DN-2000 is more open and high in the high-frequency part. It puts higher requirements on the quality of the sound source and even the quality of the music content. Compared with the UE900, the high frequency of the DN-2000 is brighter. But the style and detail are very similar. The style that is more convergent with W4R is different. If you prefer a brighter high frequency, then the DN-2000 high frequency details will make you feel more enjoyable. In the aspect of IF. DN-2000 shows different styles from several four-unit moving irons. Its performance is softer and more delicate, and its resolution is better, but the dynamic and knot images are slightly worse. The lower part of the intermediate frequency is slightly loose. In good cases, there will be better performance. In terms of low frequency, similar to the low frequency performance, the sound source needs better control, and the big dynamic in detail is not its obvious advantage, slow rhythm, low dive detail performance DN- 2000 is better than W4R, SE535 and other headphones. Of course, its dynamic performance is also satisfactory.

In general, DN-2000 may be too bright in addition to high frequency, and there are some sharp problems. The overall sound quality is indeed not lost to W4R, UM30 and SE535, especially in the sound detail performance DN-2000 slightly dominates, but large Dynamic sound level control, these several moving irons predominate. Is the price of 1798 yuan too high? We can see that there are netizens arguing under the DN-2000 atlas. Some people think that the brand of Dynaco can't hold up like this. The high price, and some people think that the sound can be compared to the W4R and other headphones can sell this price? There is no right or wrong, but as a still high profit margin of the headset products, in the case of the brand is in a weak situation, how to use It is equally important to impress users who are willing to experience your products and how to impress users with quality.
