Music Elves in Pocket-Feiao & Fei Sheng KA1 Portable Decoding Ear

[rambling]]

, if you want to ask me which model is the most recommended small tail in the 500 gear range in the past six months, there is no doubt that it will be the KA3 of Feiao & Fei Sheng, which is also the small tail with the best feedback. Because this price range can take into account the single-ended and balanced mouth, and the performance indicators are very top of the small tail, KA3 is undoubtedly one of the best choices. Because of the popularity of KA3, Feiao seems to have seen the market demand for portable decoding earphones, and Feiao has always been an action group, doing what it says and doing. Therefore, there is today's second small tail after KA3 -- KA1.

[Outside]]

, we can know from the outer package of KA1 that this small tail is still a product jointly created by Feiao and Feisheng. I introduced Feisheng when I wrote JD3 and JH3 products not long ago. This is a younger sub-brand under Feiao that pays more attention to high cost performance. The KA3 mentioned earlier is also jointly produced by Feiao and Fei Sheng.

compared with KA3, KA1 is a more entry-level product, and one of the biggest differences between KA1 and KA3 is that KA1 does not adopt a split connection method like KA3, but an integrated structure. Considering the needs of different customer groups, Feiao also provides two kinds of plugs: C- port and L-port. In addition, the shape of KA1 is almost carved out of the same mold as KA3. Founder's hale and hearty appearance, the same metal material, the same RGB round lamp, the family-style inheritance shows incisively and vividly, that is, KA1 is much smaller than KA3.

looking around, the volume of small tails on the market is getting bigger and bigger. KA1 is a bit of a return to the original intention this time. The volume is controlled to a small figure of 40mm × 15mm × 8mm. Compared with a series of high-performance small tails in my hand, KA1 has the advantage of absolute lightness, that is, it is a circle larger than the Meizu line of the first generation. The material of aluminum alloy makes K, the most intuitive feeling is that every time you go out, you insert headphones or put them in your pocket, which makes it much lighter and more convenient to carry. This is the most real experience improvement.

Of course, it is light and light. KA1 has not compromised its performance in order to control the volume. This time KA1 still inherits the high cost-effective feature of the Fei Sheng brand. Although it is an entry-level model, KA1 is equipped with a high-performance integrated chip ES9218AC PRO. The biggest advantage of this chip is that it integrates USB processor, DAC and earpiece. It has low power consumption and strong performance at the same time. Interested friends can learn about this chip. At present, the selling price of similar products using this chip on the market is much higher than KA1, even several times.

also has many bright spots in software. First of all, Feiao specially customized Windows ASIO driver for KA1. Players such as fb support ASIO channel playback and Native DSD, which seems to be the only product at the same price. Another bright spot is that KA1 supports MQA service, which is one point higher than KA3 and has more playability.

, I would like to talk about the sound of KA1. Since it is the first time to experience the ES9218AC PRO chip, besides the power consumption and heat generation are really well controlled, the most amazing thing about the sound is the great dynamic performance of KA1. In other words, we can imagine that this is a dynamic performance that such a small equipment can support, and the rhythm fluctuation in music is very complete, KA1 can also be better presented for tunes such as "Chunjiang Flower Moon Night" that test the dynamic performance of the front end. The sound field including KA1 is also a very regular circle. For the small tail at the same price, these two points have great advantages.

of the sound style, KA1 and most of my hands focus on the tail of the middle and lower plates are different. Its overall sound is more neutral. It is really impossible to specifically say whether it is cold or warm. If you have to say it more finely, you will slightly prefer the warm sound to be lost, that is, lost. The three-frequency distribution is also sufficiently balanced, and there is no obvious tendency. At present, it seems to be a safe tuning, because considering the needs of users at this price, a product with too distinctive style does not seem to be a better decision. However, the current neutral and versatile style is more suitable for popular tastes.

of my performance in trying to match some plugs that are easier to drive, KA1 is still very stable. For example, I seem to have heard a little digital flavor on IE60. For IE60, the low frequency is a success and a failure. The passionate low frequency made IE60 once a thousand yuan popular magic plug in that year. However, the low frequency performance, which was too thick and slow, was controversial. There was also the tooth sound, which could only be improved by changing the C set or the pumpkin set. However, with the IE60 after KA1, the low frequency will be relatively cleaner, and the rebound speed will be faster. Without the too strong sense of confusion in my impression, the human voice will be more delicate. It used to be said to be a big mouth. Now, the mouth shape is bigger or bigger, but it is acceptable. With this set, IE60 is like a slightly fat middle-aged man who has changed into a straight suit. His weight has not changed, but the whole person looks cleaner and more energetic. Well, that's the feeling.

and similar, there are water orioles. The quality and listening feeling of water orioles are higher than IE60. However, the low frequency also has a slightly dull problem. The sound with KA1 will be more refreshing. Although the whole is not as obvious as IE60, the difference can still be recognized by listening carefully. However, under the drive of KA1, the sound part of the water oriole can well show its density and thickness, and its sound performance is very stable. Therefore, in the water oriole, KA1 does not interfere too much with the style trend of the earphone itself, but plays a very good driving role, which greatly stretches the advantages of the water oriole earphone itself, that would be enough.

In addition, I also tried a low-resistance and high-sensitivity earplug like Jin Se Xiang Tequila pro. This plug is very sensitive to the bottom noise at the front end. Fortunately, after I plugged in KA1, the bottom noise is almost unknown. This is quite surprising, so that the already clean and transparent Tequila pro can be completely free from any noise interference.

Considering the positioning of KA1, I originally wanted to try to match Feiao's two entry-level earplugs JD3 and JH3, but JD3 was lent to group friends, while JH3 was lost by express on the way to send it back to the oil burning audition, so I had to give up. Here, I tried to match the FA7S in the hand. As a single-sided 6-unit pure moving iron earplug, FA7S has, therefore, even if KA1 is not so strong in thrust, it can be well driven, and it is not bad to make a noise. It can push a score of 6 or 7 points. Originally, it is a mild and supple FA7S. When encountering a moderate and peaceful KA1, the two hit it off, the sound is corrected, and there is no sense of discord at all. As long as it is not listening to some heavy metal rock or big, it's not a big problem.

In addition to these advantages, if you want to say the shortcomings of KA1, you can only pick and pick from the output power. As you can see, all the earplugs I matched in the previous article are relatively easy to drive products, including FA7S, which can be tried. However, KA1 is still difficult to drive if you eat front-end plugs like FD5. If the earphones in your hands are high impedance and low sensitivity, then I really don't recommend starting with KA1, you can go out and turn right to learn about KA3, yes, KA3 also has a balance port ~

, I personally think KA1 is a product that can better reflect the precision of Feiao knife method. While effectively controlling costs, good steel is used on the blade. They know very well what is most needed to burn oil in this price range. Before KA1 appeared, the small tail within 300 was worth recommending, and there were not many. The appearance of KA1 filled the gap in my recommendation list. In the words of Master Kang, KA1 makes friends if it doesn't make money ~
