ATH-CKN70 is an in-ear earphone listed by the Iron Triangle last year. The price is more than 400 RMB.
The CKN70 has a slender shell and looks like a moving iron earphone, but it is actually a moving coil, but the micro-motion coil will continue to be introduced later. The outer casing is made of metal aluminum, and the strength is definitely higher than that of plastic. The official saying is "high rigidity." The machined aluminum casing reduces excess vibration. In fact, for headphones, the housing is relatively thick enough, even if it is plastic, unless it is too thin. Metal does not have an advantage in acoustic performance. The metal has a beautiful texture and is easier to process.
Unlike other in-ear headphones, the CKN70 has two plastic ring rings for support and card slots, making it difficult for headphones to fall off. This design is called NLS [close to the ring support structure] by the iron triangle. The effect is limited, it may be that our ears are not compatible enough, but the decorative effect is still there, this ring is the iconic appearance feature.
The CKN70 uses a micro-coil speaker. The micro-coil is no stranger to us. The JVC FXC51 and VSONIC VC02 that we have evaluated before are also micro-motion rings. The difference between the micro-motion ring and the traditional dynamic speaker is the diameter. The dynamic speaker, most of the diameter is more than 10 mm, and the diameter of the micro-motion ring can be less than 6 mm. What are the benefits of small? If you use the traditional moving coil to design the in-ear speaker, the speaker is placed in the cavity. Then, the sound is exported through the catheter, and the derivation process will produce unavoidable distortion. Because the diameter of the catheter is smaller than the diameter of the speaker, the sound waves will squash and reflect each other. With the micro-coil, the speaker can be placed as far as possible to reduce the catheter. Side effects. From this perspective, the micro-motion ring is more suitable for in-ear headphones.
According to the official data, the new carbon nanotube diaphragm is used, which is a kind of material which is excellent in strength and toughness and can be made into a very thin material. However, the official does not introduce too much, and the diaphragm is pure carbon nanometer. Tube, or composite diaphragm, or coating what is not explained, only use "can achieve perfect sound quality" to interpret.
In the actual listening test, the Apple Nano 6 player and the vivo Xplay 3S mobile phone were used as the sound source. The sound of the headphones was dull, but after 40 hours of downtime, it still improved little.
The CKN70 sound has a stiff style, no aura, and a little dull detail. It is a very annoying style. Its high frequency performance is not good, the extension is not enough, the sound is rigid and the details are small, the hard style The high frequency presents a metallized style, but there is no analytical power of the metal sound. The intermediate frequency also deliberately pulls up in the high frequency band, which makes people feel more refined and morphological, but also Let the younger female voice become very heavy, such as Adele, Bjork, The Corrs, Fredrika Stahl, etc. Pulling high and high frequency is a common tuning method for many headphones, which is very common, but we think that CKN70 has overturned. Moreover, The intermediate frequency is the gene area of many instruments. Adjusting the medium and high frequency may affect the texture of many instruments, such as bagpipes. After the CKN70, it shows a metallic taste. This is too strange. The low frequency also has obvious modifications. The low frequency is "strengthened." "The past, but not the soft "ultra-low frequency" that the rookie likes to see, but the hard-slung dragging low frequency, its low frequency transient is not good, easy to turbid, the strength is not good, there is no texture at all.
The overall performance of the CKN70 is restrained and twisted. The sound field is not wide and flat, the level is lacking, and the resolution is obviously insufficient. In the performance of a burst of music, there will be a mess, in a state of basic out of control, a song Adele "Roling in the Deep can make its original shape reveal, the middle and high level are mixed together, and it has its own drum sound effect. Its performance is very disappointing, this turned out to be a 400+ price earphone.
Compared to the previous tests of JVC FXC51 and VSONIC VC02, CKN70 sound quality is not competitive, the price is not competitive, compared to the 100 yuan earplugs, CKN70 has no chance of winning.
