Good Sound Supplement: FIIO (Feiao) Q1 Portable USB Decoding Ear Lovers Sharing!

, at the FIIO (Feiao) new product launch conference on September 12, the vast number of music enthusiasts and enthusiasts jointly witnessed the "Six-Pulse Excalibur" move released by Feiao in the second half of this year. Of course, the most concerned and eye-catching one is the non-destructive music player X7, which is currently the flagship level. Today, it brings you another new product released on the same day, focusing on portability, -- Q1, a cost-effective product that combines (DAC) decoding and ear placement functions, happens to be a new DAC ear placement that is priced only in 448 yuan recently and has been officially put on sale.

, Q1, which looks like a portable hip flask at first sight, is actually a brand-new sequence product developed by Feiao. Although it is positioned as an entry-level product, the first impression is that it has a very tasteful style. The mysterious and deep dark sandblasting process baking varnish decorates the whole metal shell with reduced electromagnetic interference to be restrained and strong and domineering. The packing box is familiar, in fact, it should be said that it is designed with reference to the outer box of Feiao X1 lossless player, which also confirms its identity of positioning entry decoding ear, but low price does not mean low quality.

is an audio product that is mainly portable, everyone must be very concerned about the three-dimensional size and weight of Q1. It should be said that the size of 97mm x 56mm x 13.1mm plus the weight of only 100g with battery, Q1 is still very portable. The most intuitive feeling is to compare the existing Feiao X5 in the author's hand and find that not only the volume is reduced by one circle, it is also nearly twice as light in weight. In addition, it should be mentioned that the grip feels, because the width of Q1 is 2mm narrower than that of iPhone 5S, so even the brother-in-law with small hands can be easily controlled for a long time. In addition, the soft and smooth sandblasting shell has no jerky touch.

talk about the perfect color value and technology, and then share with you the core of Q1. First of all, the DAC chip as the decoding part uses the BB PCM5102 of TI company with high attendance rate and initial burn. It is characterized by the advantages of high signal-to-noise ratio and low distortion, and improves the tolerance of clock jitter with excellent dynamic performance; the amplifier chip as part of the ear amplifier uses Maxim's MAX97220, which has the advantages of high current output and low running power consumption, as well as extremely low distortion and high signal-to-noise ratio. The 1400mAh polymer battery capacity built in Q1 can ensure a long endurance of about 30 hours, while the official recommendation for thrust is to adapt to 16-150 ohm impedance headphones.

, by the way, what is (DAC) decoding, because many netizens who have just come into contact with audio products actually don't know its usefulness. Of course, burn friends can ignore it. A deeper answer can ask Du Niang. The so-called (DAC) decoding is the process of converting digital signals into analog signals. Whether it is lossless player, computer or mobile phone built-in storage files, they all exist in the form of digital bytes, the same is true for the audio files, so the only analog audio signal that can be recognized can be transmitted if the physical speaker unit needs to work. The "trader" in the middle is (DAC) decoding.

At the bottom of Feiao Q1, the interface and operation from left to right have been identified in the above figure. What needs to be analyzed is that the first jack is a common interface. When Q1 is used as a decoder, this port is used as a LINE OUT; when the ear is used, it is used as an analog input interface (AUX IN). However, the rightmost charging selector switch can only be charged when it is selected to be in the ON state. Of course, it can be charged while using it after it is turned on. It can be selected independently. The consideration of charging only if you want to charge is quite humanized.

Feiao Q1 is that the status indicator is divided, and the working state blue light is always on; the red light for the charging state is always on, the green light is always on when the full charge is switched to the green light, and the red light flashes when the power is low; by the wayQ1are JapaneseTOCOSpotentiometer, quality is worth circling.

From this angle, it can be seen that the adjustment knob has vertical stripes that increase friction and anti-skid, and is marked with a volume adjustment reference range value from 0 to 9; in addition, I personally think that the control damping of the knob is moderate, and it is not loose or tight.

first shares with you the advantages of Q1 as (DAC) decoding. Whether connecting computers as external sound cards through USB data lines or connecting most smart phones through OTG lines, the function of hardware decoding can be realized without additional driver installation. It is known that most home computer sound cards are partially realized by integrating chips on the motherboard, and hundreds of entry-level sound cards are not ordinary players willing to spend money on a fixed hardware to improve their listening sense. Of course, knowledgeable PCHiFi players all know that the disadvantages of integrated sound cards are general thrust, general noise reduction capability, not to mention low sampling rate, and inability to support the awesome ASIO drive. Therefore, it can only be called listening to songs, not to mention enjoying music. As for mobile phone decoding, it is basically the soft solution of processor operation, because the lack of core decoding hardware makes it impossible to feel the music details of high resolution and pure noise brought by professional audio chips. Although some music mobile phones have used customized audio chips in the past two years, unfortunately, due to power consumption and endurance and other reasons, whether the decoding or amplification module is almost a castrated version with low voltage, the final performance of HiFi is not painful, the concept outweighs the effect.

After the Android smart phone used by the author for this demonstration is connected to Feiao Q1 through OTG switching USB cable, the Haibei music application running on the mobile phone will automatically prompt the USB device to be recognized and played after decoding by the device. At this time, the earplug is inserted into the 3.5mm earphone hole or the lower line output hole, and the improvement of the listening quality brought about by Q1 decoding can be felt. Not only is the details of the song, moreover, some saliva pop songs that were originally simply mixed with ears have also become more musical, full of charm, and listened to a lot. Of course, the difference between the earphone hole and the line output hole is that the earphone hole is decoded and then amplified by Q1, while the line output hole is straight out of the original LINE OUT.

, if it is used as an ear release function to connect a lossless player, dial the gain to H, and after BASS is turned on, the effect improvement is very obvious. For example, with Feiao's own X5 generation, the previous X5, which was originally used to monitor the music feeling of straight and white style, instantly had the special effect of changing clear water into chicken soup, especially the voice began to warm up, however, more tracks have changed in different levels regardless of the thickness and amount of music. This is probably what it means to make male voices thicker and female voices more poisonous.

for such a small artifact with two materials, which not only retains color value, taste and exquisite figure, but also has audio decoding and signal amplification, Feiao has made it give full play to the maximum light and heat as much as possible. If some netizens pay more attention to listening to songs and expect to spend at least money to realize this long-cherished wish, I believe this entry-level decoding earpiece Q1 will be a good choice for you, just use the existing notebook, mobile phone, entry-level lossless player around you, and match it with a portable Q1 that helps you to listen to and not expensive, and you will instantly experience a great improvement in your perception of music.
