beryllium plating blessing, the best choice for entry-Feiao FD1

when it comes to the entry price of HiFi products, we have to mention Feiao. Except for the small tail that has not been touched (temporarily), basically every type has very cost-effective products. And this time Feiao even used the beryllium plating unit on the entry-level FD1. Is the poison on the upper body and sound equally toxic?

package. The earphone body can be seen after the magnetic flip cover is opened. The accessories include 3 pairs of low-frequency sleeves (red tubes), 3 pairs of equalization sleeves (black tubes), 1 pair of sponge sleeves and a plastic storage box with considerable volume. However, the point to be complained here is that neither the packing box nor the internal instructions explain the difference between the low-frequency sleeve and the balanced sleeve. Users can only distinguish by ears, which is not intuitive.

wire adopts four strands of high purity single crystal copper, a single strand of 30 cores, litz structure, and the wire body is very soft and comfortable. The panel is made of celluloid. My one is a black panel. The refraction effect is not obvious. It looks more stable. I believe blue will look more lively and beautiful. Although it is not an integrated shell, the joint control of the panel and front cavity is excellent, and it is not easy to detect without careful touch.

At the same time, there is still a mystery in the cavity design. With the balanced pressure relief technology of the front and rear cavities, it can bring more natural and excellent low-frequency performance and improve the pressure of long-term listening. The sound mouth and filter screen are all made of metal, and Feiao can see and touch the work seriously. In terms of the unit, the beryllium-plated diaphragm unit with N50 double magnetic circuits is adopted. The diaphragm has stronger rigidity and faster, which can also bring better dynamic transient and low frequency performance.

I prefer the performance of the low-frequency set under the original wire. On the contrary, the balanced set gives people a feeling of restraint, which limits the stretching of both ends and has less details than the low-frequency set. Thanks to the balanced pressure relief technology of the front and rear cavities, the upper ears of FD1 will not bring oppression discomfort to people, and the sound field is cheerful and natural, which is rare for an entry-level earphone.

sound performance also gives people enough surprises. Beryllium-plated diaphragm brings better low-frequency performance. Whether it is volume diving or transient dynamics, it is the same price leader, and it gives people a refreshing and transparent feeling as a whole. However, the disadvantage is that it is relatively "tight" and lacks some loose feeling of moving circle. It can be said that this is not a moving ring earplug that takes the "taste" route, but belongs to the "quality flow" faction. The intermediate frequency performance is relatively simple, without obvious dyeing, but it is slightly thin and lacks some thickness. If you listen to a clean Japanese female voice such as KOKIA or too tea, it will be more appropriate. The lip-to-mouth details are well restored, but if you listen to aimer or Adele, it is not appropriate. Of course, this does not mean that ordinary saliva pop songs cannot be listened, the Zeno type or the low-frequency element FD1 required by the European and American fashion can be better weighed, and it does not blow the head or muddy, which is understandable for an entry-level HiFi headset.

In fact, FD1 has relatively good compatibility with all kinds of music under the original line. Even if I listen to the original sound of Hans Dimer's movie, I can feel its good sense of energy. However, as mentioned earlier, FD1 sound is generally thin, and the orchestral ensemble will still appear to be insufficient when it appears. It is more suitable for small-scale string music, such as my favorite oxtail constitution, which is the sound shape and, FD1 can be better controlled. This also made me begin to explore the potential of FD1 as a "toy". The original line was almost meaningful in depth and longitudinal separation. At the same time, the high frequency seemed to have less shiny feeling. Therefore, without saying anything, I directly replaced it with a single crystal copper-plated palladium line (although the price was several times that of FD1).

Facts have proved that the unit quality of FD1 can be further squeezed by changing the peripheral accessories. Under monocrystalline copper and palladium plating, the sound field can be clearly opened and there is no obvious sense of margin. The positioning of the instrument is clearer and more regular and better separated. At the same time, the mouth shape of the human voice has been better portrayed and the lines are clearer, but unfortunately the human voice still lacks some "monosodium glutamate flavor" (after replacing the gold and silver copper wire I have on hand, the human voice moisture will increase, or You can choose to use the E set, but the whole will become mushy and the high frequency will be cut off a large section), this set of collocation makes FD1 a better, especially when the extension of the two ends is strengthened, the tone of the piano and violin is more brilliant, the low frequency of the cello is more plump, and the toxicity is more intense.

, FD1 can be used as a plug to establish sound cognition for newly-fired users in into the pit. It is easy to push and has a relatively balanced tuning. The good quality of beryllium plating unit can also meet their special preference for "analysis". The design of replaceable lines also brings more playability. Of course, this may be a higher-cost gameplay and is more suitable for burn lovers with certain experience to try, however, it is OK to change the earmuff and taste different tastes. The original offline can already make FD1 have good competitiveness at the same price. It is a good choice for entry and a unique toy. This also makes me look forward to what kind of surprise the next one will bring us ~
