mobile phone listening to songs? Feiao Decoding Ear Q5

, I always used to confuse Feiao's new decoding earpiece Q5 with the portable music player X5 III, which is also owned by Feiao. I always felt that Q5 was the X5 III with the screen removed. The fundamental reason for my cognition is that Q5 and X5 III use exactly the same decoding chip and low-pass filter, both of which are dual AK4490EN and dual OPA1642. However, when I saw the familiar replaceable ear module AM3A on Q5's chin, I gradually realized my mistake. To be precise, Q5 should be on a horizontal line with X7 MKII. They can share the same model of Feiao Ear Module, and the sound quality performance should be the closest.

in terms of functional design, Feiao has always been good at making all-round products. Whether it is a player or a headphone amplifier, the integrated functions are integrated. Therefore, Feiao's products have always been deeply loved by "engineer thinking" enthusiasts, including myself.

, this Feiao Q5 has very rich functions. Its basic function is a headphone amplifier with decoding, and then supports various input and output interfaces, such as coaxial, optical fiber, line, USB input, and analog (2.5mm balanced 3.5mm) output. In addition, there is my favorite Bluetooth wireless connection, and it is Bluetooth 4.2 version of Bluetooth, which supports Qualcomm Apt-X codec and can enjoy high-definition digital music wirelessly.

because there is no screen, Q5 lacks the main control chip, graphics processing module, touch component, etc., but the selling price is still 100 yuan more than X5 III. Originally, I thought that without the main control chip, the battery life of Q5 can be longer under the same capacity battery, but in fact it is basically the same as that of X5 III, which shows that the power consumption of Q5 audio circuit is still relatively large.

Q5 uses Xmos USB Audio platform, which can support rich interfaces and can be connected with mobile phones, including Android and iOS systems. It can also be connected with Windows and Mac OS systems, and even connected to Sony players through Sony's WM Port interface. However, in terms of selling points, Feiao still emphasizes that this Q5 is Made for iPod/iPhone/iPad. It is still very difficult to pass MFi certification. Feiao is understandable in promoting products. Q5 is the most convenient to connect with Apple system, because it does not need any operation, plug and play, especially convenient. However, if the connection with the Windows system is used as an external decoding of the PC, additional drivers need to be installed.

In terms of decoding, Q5 supports PCM decoding of up to 32bit/384KHz. In addition, Q5 also supports DSD decoding and can solve DSD256 standard. In terms of decoding performance, Q5 is already one of the most powerful decoders at present, and the existing music resources are fully supported.

this Q5 also has a special humanized design, that is, the charging and data interface are independent, so that electricity will not be stolen from the mobile phone when connecting to the mobile phone. Many digital decoders on the market steal electricity from the mobile phone when they are connected to the mobile phone. When they are used, the mobile phone is often dead and the decoder is fully charged, which is very embarrassing.

, there is another point worth mentioning. When Q5 transmits Bluetooth, audio decoding is not completed by DAC built in Bluetooth chip, but by Xmos and then transmitted to AK4490 to finally complete DAC. The sound quality performance is much better than the Bluetooth wireless music we usually hear.

Q5 is at the same level as the previously released X5 III and X7 MKII, which is also one of Feiao's best products so far. The body of Q5 is made of aluminum alloy through CNC process, and its integrity is very strong. The front side is made of wire drawing process to highlight the texture of metal, while the back side is decorated with PU leather, which has anti-skid effect. In addition, it can avoid damage caused by mutual friction when binding mobile phones or players, killing two birds with one stone.

the current audio products, it seems unprofessional not to have a large volume knob, so whenever the design allows, there will be such a conspicuous volume knob. Q5 is no exception, but its volume adjustment is not a traditional potentiometer, but the adjustment principle of ADC, which will not change physically with time, and the adjustment accuracy is higher, reaching 256 level.

in terms of volume, Q5 is slightly smaller than X7 MKII, with a fuselage of only 124 × 64 × 16(mm), but its weight has reached 195g. When used as a decoding ear amplifier, Q5 has a battery life of about 10 hours. If only the ear amplifier function is used, the battery life can reach 20 hours. In addition, when there is no external signal input, the system will automatically shut down after 10 minutes to save power.

PO is output, the power of Q5 can reach 150mW and the balanced port can reach 400mW under 32 ohm impedance. It is no problem to push most headphones. In addition, it has a gain switch and a bass switch, both of which are quite practical.

After connecting the iPhone with the MFi-certified short-term in the accessories, the mobile phone does not have any prompt, so it is enough to plug in the earphone and play music. This is really extremely convenient. There is nothing to drive, plug and play, and use in pure fool mode. This is worth learning from many manufacturers.

the first ear can clearly hear the sound after Q5 processing, which is different from the sound directly output by iPhone. The sound field and stereoscopic impression are not at the same level. The voice from Q5 has a stronger sense of presence, a lot more details, the longitudinal sound field has been enlarged, and the voice has become more ethereal, increasing the imagination space in the mind. This kind of space is real space, not at all ethereal. Its medium and high frequency is relatively strong, low frequency elasticity is abundant, diving in one step, can not hear any meaning of procrastination. Generally speaking, if the medium and high frequency sound is strong, the overall hearing will be dry, but the sound of Q5 is wet, and there is an indescribable "sweet" feeling when listening to female voice, which is also difficult to find on the higher-end X7 MKII.

if you turn the gain switch to L and turn off BASS, its voice will be slightly darker and its voice will be slightly farther away, feeling that it will suddenly return to the level of X5 III: there is a trace of weakness hidden in the sturdiness, and there seems to be more caution in the unruly. Originally, I felt a little peaceful, but I didn't seem to feel this way. From the perspective of listening, I still like to turn on both switches, but later when I tried the Flow headset, I found that the sound after turning off was more beautiful, so it was not absolute, and it depends on the specific headset.

, under the influence of Apple, many brands in the Android camp have also canceled the 3.5mm interface one after another. Listening to wired earphones requires a small tail. In this case, if there is still some pursuit of sound quality, you may as well bundle decoding earphones for use, and the sound quality improvement is very obvious. The decoding capability of mobile phones is mostly weak, but its advantage is that it is convenient and quick to obtain music content. Even X7 MKII, which supports WiFi function, is not as convenient to download music directly by installing a third-party APP. In the current portable system, mobile phones are actually the most suitable device for "turntable. The significance of Q5 lies in solving the problem of weak decoding ability of mobile phones. Besides being used with you, Q5 can also be connected to computers or high-quality active speakers. It is a quality product that meets the current consumer demand.
