The first price of as long as 269 yuan Fei Ao new small tail KA1 this time is completely a revolutionary posture, so that the entire small tail market including those who have just been involved in the small tail field of mobile phone brands out of a cold sweat, so play, mobile phone brand related small tail product competitiveness is exhausted, plus this accessory product popular less than two years, there is no feeling to speak of, the road ahead must be more difficult to go.
Of course, for end users, especially those who want to improve the sound quality of mobile phones, tablets and laptops, the arrival of Fei'ao KA1 has undoubtedly lowered the threshold for professional audio tails. When I learned that KA1 supported ASIO drivers, I felt the need to make one by hand to play.
A while ago to an animation to do mixing, because the newly installed computer does not have a separate sound card, the quality of the motherboard integration is relatively poor, the preview in the Audio is very satisfied, but the final PR output found that part of the mouth shape has a slight misalignment, so obsessive-compulsive disorder was committed, but unfortunately tossed for a long time did not make themselves satisfied, then only thought of the previous use of the old computer has never had this problem is that the sound card supports ASIO, Under this premise, I was very excited when I learned that Fei ou KA1 supported ASIO on The Windows 10 system, and it could also be used on the Macbook Pro to improve the sound quality of the laptop, 269 yuan can be said to be too worthwhile.
After arriving at hand, my first attempt is ASIO, put a driver on the computer, set up a good set to see ASIO successfully started, casually listen to a few familiar songs, the ears are very comfortable, and the sound directly inserted in the computer motherboard integrated sound card 3.5mm headphone hole is completely two grades, the sound quality of the motherboard integrated sound card is like the original MP3 player, and the sound quality of the KA1 output is like the current portable HiFi player, its sound layering, fullness, Tolerance is simply two outrageous spans, and AB is highly judged when compared.
Compared with vivo sound quality cow X's HiFi mobile phone XPlay6, the actual difference is also very obvious, KA1's sound energy sense is more sufficient, the details are explained particularly carefully, the low frequency has a certain but not contradictory grainy feeling, it seems very sharp, sounds more three-dimensional, and the high frequency is just the opposite, sounds moist, refreshing. I even took out the M11 Plus that I reviewed a while ago, and in addition to not having the smooth sound of the M11 Plus, I really can't find a particularly obvious deficiency. The KA1 reminds me of the Lotto Pico I played a long, long time ago, which is a small audio product that can burst out amazing energy.
From the packaging can also see the strength of Fei Ao KA1, passed the Hi-Res certification, used the ESS decoding chip, support MQA fully unfolded playback, the box also printed less DSD hardware decoding, and the personal computer connection when the highest solvable DSD256 specifications, even with the audio performance weak front end connected, through the DoP mode can also do DSD128 decoding, which is simply a professional HiFi player performance parameters a few years ago.
There are not many low-priced accessories, in addition to the KA1 body, there is also a Type-C to USB-A adapter for connecting to a standard computer. The workmanship of KA1 itself can be said to be excellent, and the workmanship of this USB adapter is very general.
KA1 is small enough to have no friends, the three circumferences are only 40X15X8 (mm), the weight is only 10g, but it uses a magnesium aluminum alloy shell, in addition to being strong and durable, the texture of the product is far beyond the level of its pricing.
Also on the back is the Jade Audio Logo, a Flying Pride online sales brand that has been tepid. The most recent entry-level products are this dual-brand strategy, using the mature, reliable, cost-effective, and high-impression Fei Ao to bring the not-yet-established Jade Audio.
The previous KA3 is a live wire, both ends can be pulled down, but KA1 in order to save costs, and the body connection end directly made fixed, but this wire is still very exquisite, for the single crystal copper surface silver plating wire, multiple strands twisted together, the value is also good.
The output interface has only a 3.5mm headphone port, which can be seen to be for entry-level audio users, and good steel is used on the blade, reducing unnecessary waste, after all, the headphones on most people's hands are now 3.5mm plugs. Even for some high-end headphones, 3.5mm plugs must be available.
Look at the volume comparison between KA1 and the predecessor KA3, in contrast, KA1 is more suitable for use with products such as mobile phones and tablets, after all, in this kind of product, portability and sound quality are equally important. The reason why KA1 can be so small is because it uses the ES9281AC Pro integrated decoding chip, which contains three major parts: USB data transceiver, DAC digital-to-analog conversion, and AMP output amplification, which are not only small in size, but also much smaller in power consumption than the split type.
In terms of performance, KA1 supports up to 32bit/384KHz PCM decoding, as well as native state DSD256 specification decoding, and MQA format can be fully expanded, which is very important for some MQA streaming platforms, online can hear MQA fully unfolded sound quality, think about it is very exciting. If you don't understand the performance level expressed by these parameters, understand it like this: basically all the digital specification music you can buy, including almost all the free high-specification digital music you can download, can be decoded and played on KA1. Don't say anything about DSD512, in fact, almost all the DSD512 in the hands of burners is fake, here is not to explain the reason, everyone is happy.
Like KA3, ka1 also has a decoding status indicator on the front, blue indicates that the current music is sampled below 48KHz; yellow indicates that the sample is above 48KHz; green indicates that the music is currently in DSD format; and purple indicates that the MQA is expanded for rendering and playback.
Ka1's sound quality far exceeds what its pricing should be, which is what Fei O has always done with entry-level audio products. And KA1 supports multi-platform multi-device, such as Windows, Mac, iOS, Android, these are compatible, product categories include mobile phones, tablets, computers, players and other digital front-ends, it should be noted that when connecting mobile phones to use, the Android system must first open the USB Host function, and iOS needs to choose the Lightning line version when purchasing. 269 yuan can not buy a loss and can not buy a fool, although the words are vulgar but the meaning is very accurate.
