Black Jade, DK-3001 as the recent hot two fever-level headset products, since its launch in the circle of friends caused extensive discussion. The same four-unit iron composite structure, which is weak, and who is selected, is often the focus of discussion. As a lucky friend who has the privilege of having both products at the same time, I would like to talk about these two distinctive products from my own perspective. As the first high-end hifi earphone for the elderly studio, the black and yellow cymbal boldly used the relatively rare voice Yang compound high-frequency, medium-frequency moving iron unit (unfortunately, the author does not know the specific model), supplemented by 10mm dynamic circle unit, constitutes 3+1 round iron combination. The outer shell adopts the black resin material mould design, which can change the private film. The wiring uses manual preparation of 6N single crystal copper (OCC), supplemented by a 0.78mm dual pin interface. The DK-3001 is the latest flagship ring-iron hybrid headset from Dainhenko. It uses the classic ROK TWFK-30017 composite high-frequency, ED-29689 full-frequency moving iron unit (used as an intermediate frequency) to match the 13mm self-developed LCD. The diaphragm dynamic coil unit constitutes a 3+1 coiled iron structure. The unit cavity is made of stainless steel CNC and it is durable. The wire part is consonant with a single-ended, balanced 5N single-crystal copper, using a standard MMCX interface with a bayonet design. Both are based on black and white tone + product main diagram based cardboard packaging design, more simple and beautiful. In terms of accessories, the configuration of the black-yellow metal storage box, four pairs of silicone sleeves, a pair of sponge sleeves, a clip and a cleaning brush is somewhat shabby compared to the Dainuke Group, which is known for its “Buy accessories for earplugs.†, DK-3001 waterproof storage box +4 pairs of silicone sleeves +3 pairs of extended silicone +4 pairs of spingfit sets of +1 pairs of comply sets + aircraft head +6.35 adapter + clips of luxury configuration, people inexplicably have to earn To feel... Both are worn around the ear and cannot be worn in the right direction. For me, the wear of the black and yellow skull is not very comfortable - too large a cavity with a short catheter, when using the original silicone sleeve, you must insert it into the ear canal in order to ensure tightness and prevent the cavity from sliding off. The ear can often be topped up. The auscultation effect brought by the thick wire is also very obvious. Of course, choosing a long silicone sleeve with a catheter and using a back line method can effectively avoid the previous problem. For friends with a sufficient budget, it is highly recommended: Change! private! mold! ! ! DK-3001 is more comfortable to wear than a black and yellow one. The smaller size of the cavities and the number of earplugs will always suit you. Of course, before a friend had feedback on the problem of protruding inside of the cavity, I strongly recommend adjusting the angle of wearing it down and trying to wear a USB flash drive similar to that of EXK. After insertion, the cavity is pulled up slightly. The black and yellow skulls and the DK-3001 all have good qualities. The analysis is good. Although the sound field is not very broad, they are all three-dimensional and structured, and they all come together to satisfy the ears of the Chung-Jing Wenrun tuning course. Black and yellow 鹂 鹂 鹂 鹂 鹂 鹂 鹂 鹂 鹂 鹂 鹂 鹂 鹂 鹂 鹂 鹂 鹂 鹂 鹂 鹂 鹂 鹂 鹂 鹂 鹂 鹂 鹂 鹂 鹂 鹂 鹂 鹂 鹂 鹂 鹂 鹂 鹂 鹂 鹂 鹂 鹂 鹂 鹂 鹂 鹂 鹂 鹂 鹂 鹂 鹂 鹂 鹂 鹂 鹂 鹂 鹂 鹂 鹂 鹂 鹂 鹂 鹂 鹂 ì´ DK-3001: At the beginning of the sound, the sound will be tight and the high frequencies will be slightly dry. But - where there is a moving circle, there will be a chance to use the "opportunity" metaphysics. When using 50+ hours, the voice of the DK-3001 will have very obvious changes, and the advantages will gradually show up, and the high frequency will gradually become warmer. , delicate, IF calm and full of emotions, low-frequency has become full of flexibility, the entire plug is no shortage of strength with the black and yellow enamel. After several months of use, the sound performance of the DK-3001 has grown more mature and stable over time, and it can accurately reflect the sound trends of different front-ends. The black and yellow blemishes made the author a bit regrettable. High-frequency part: The high frequency of the black and yellow dragonfly has good brightness and ductility. When it is played with a violin, piano, cymbal, zither and other instruments played by the front end of the Zhongzheng such as DX200 and 901U, it is transparent and refreshing. However, in the case of a front end with a brighter sound base, the high frequencies will appear to be "overly bright", and they may appear a little stimulating when they encounter vocals with more problematic tooth sound recordings. DK-3001 is darker than black and yellow, and the first feeling at high frequencies is not so bright, but there is not much difference in resolving power and extension. When performing the same high-frequency-intensive instruments, it is not as good as black and yellow, but also Can do more accurate reduction. Thanks to the proper attenuation of the DK-3001 in the band where the tooth sound is located, the control of the vocal tooth tone is significantly better than that of the black and yellow ray. IF section: The medium-thickness medium of the black-yellow cormorants is moderate, and the whole is loose and slightly prone to sudden protrusion. There is a faint sweetness in the interpretation of the vocal - this is probably the so-called "bird's taste." This kind of dyeing can be seen as a matter of opinion. Some people may find it tempting, while others may find it inaccurate. Similar to the black and yellow dragonfly, the DK-3001's midrange is also warm, relaxed and slightly prone to sudden changes. The difference is that the DK-3001 lacks a bit of "sweet" dyeing of the black and yellow dragonfly, which is even more positive, with the A15. The heavier front end of the class showed better compatibility and was more resistant to hearing. The low-frequency part: In the early stage of use, the low-frequency performance of the black and yellow dragonfly is impeccable - loose and elastic. Unfortunately, with the accumulation of time, the low-end dynamic coil sounding floor shows a clear slackening tendency, and the loose low frequency becomes increasingly difficult to control. In the faster and low-frequency-intensive music, the low-frequency dispersion of the black and yellow ray Slow and lack of flexibility, there is a clear sense of disconnection with the high-frequency. The low frequency of the DK-3001 is well-placed in terms of speed, dive, flexibility, and reverberation while maintaining a proper sense of volume. Whether it is the interpretation of low-frequency electronic dance music, or the magnificent classical music, the DK-3001's low-frequency transient performance is very good, with a degree of relaxation, freedom. The DK-3001 is also a circle iron product that I have heard of nowadays. Black and Yellow: After using the late Black and Yellow Dragonfly, it is strongly recommended that you replace your own W03/04 upgrade line, which can greatly improve the problem of slow bulking at low frequencies. For earplugs, it is recommended to use the same length of silicone tube as the original silicone sleeve. UE silicone sleeve is highly recommended! DK-3001: Wire using standard single-ended/balanced wire will get good results. If you want to improve the quality on the basis of maintaining the original style, it is strongly recommended to use Dainyin's own 7n single crystal copper upgrade cable (2k2 inner section, cheaper It's easy to use, most people don't tell him (*^_^*))! Earplug part, with its own white silicone sleeve sound the most balanced, long sleeve can increase the low frequency, slightly weaken the high frequency, please use as appropriate (sf and c sets are strongly not recommended ... Do not ask me why). Black and yellow 鹂 & DK-3001 as the current domestic 4 unit ring iron mixed products, the sound is indeed angry about the strength of foreign big names, but also should prove that a certain engineer Darwin "domestic headphone factory is not lack of technology," this sentence . With domestic companies such as hifiman, dankeke, raosound, and dita, the previous high-end headsets have become more and more exclusive. The domestic products are also able to make real fans happy. pride.
