to save the sound quality of mobile phones. FiiO flagship Bluetooth decoding earpiece Q5s is evaluated

Although the sound quality of listening to songs on mobile phones is generally poor, a large number of users still choose to listen to songs on mobile phones. The reason is very simple, that is, the inexhaustible rich music content of various music apps on mobile phones. In this fast food era, few people perform the complicated steps of downloading first and then copying to the player to enjoy music. This also explains the fundamental reason why Bluetooth music headsets are so popular, and sometimes simplicity is the last word.

part of the reason is that the advent of the era of genuine digital music and the improvement of the quality of online music have jointly promoted the development of the industry and made it easy to listen to and buy songs. At this time last year, I still bought songs through QQ music and downloaded them, then exported them and copied them to the player for listening. At the beginning of this year, I didn't do it. When I was squeezing the subway, I used Bluetooth wireless headphones. When I calmed down and wanted to enjoy it, I plugged in a decoder and connected to a wired HiFi headset. The advantage of this is that you only need to find songs and buy songs on your mobile phone. It is simple and convenient to listen wirelessly, and you can connect a decoder when you want quality. It will always bid farewell to the trouble of downloading and exporting to different terminal playback devices.

mobile phones has accompanied me through more than 100 wonderful nights. Recently, its upgraded version Q5s has been on the market again. After a preliminary look at the hardware parameters, the decoding chip model has been changed, and the operation has also been improved. My favorite long-press switch has been changed to a rotary switch that is integrated with the volume knob, so it is necessary to experience the performance of the new Q5s.

, two years ago, I thought FiiO Feiao's packaging style was of high grade. Now I am really tired of aesthetics. It is time to change. I strongly suggest that the manufacturer consider my proposal.

mainframe. I took it off in order to take photos. At first glance, it is really the same as my Q5. People who don't understand look a little silly and can't tell.

accessories can be called "flagship", which is too rich. There are four additional screws for replacing the ear card. There are a total of four straps. I haven't used one of Q5 straps so far, because it is more troublesome to operate with a mobile phone and can only be used when tying the player.

left to right are three short connecting wires, Line in, coaxial and Lighting. Lighting of them are authorized by Apple and belong to genuine wires. Feiao itself has passed Apple MFi certification.

fiber and coaxial share an interface of Q5s, there is a fiber adapter in the accessory. The other is to replace the screwdriver and USB data cable of the ear card.

mesh bag seems to be to install the Q5s host, but it cannot be operated after installation, so it should be used for storage, and it must be streaked when used at ordinary times.

Q5s and Q5 are very similar in appearance, it is difficult to distinguish them without looking at details. The main frame of Q5s is made of a whole aluminum alloy CNC, which is very strong and heavy.

is covered with a layer of PU leather, which avoids the possibility of grinding the mobile phone when it is attached to the mobile phone. In addition, the Bluetooth antenna receives signals wirelessly through here.

Q5s has passed the dual Hi-Res certification, namely Hi-Res Audio and Hi-Res Audio Wireless. It abandons the independent key design and integrates the startup and shutdown into the volume knob, which is more in line with our daily operation and usage habits. Some people may worry about whether such volume adjustment design will have the problem of partial tone. In fact, we can rest assured that the volume adjustment of Q5s is not a traditional analog potentiometer, but is reconstructed by ADC curve (NJR NJW1195 scheme in Japan), and the adjustment accuracy is impeccable. The NJW1195 consists of a 4-input 2-output selector and a 4-channel electronic volume regulator. The output noise voltage is only-118dBVtyp, and the distortion rate of single-wire transmission is only 0.0025% typ.

The design on the right side of the host is different from Q5. The original power switch key is changed into the input channel selection key. Four independent LED status indicators are also designed below. Make the audio signal input display more intuitive.

Q5s comes standard with Feiao's most popular AM3E ear module at present. It has three output interfaces of 3.5mm standard, 2.5mm balance and 4.4mm balance. When matching headphones with different plugs, it is no longer necessary to connect the switch head.

friends who have played FiiO Q5 all know that in order to prevent the problem of "stealing electricity" from the mobile phone when connecting to the mobile phone, Q5 has designed an independent charging port. On Q5s, the independent charging port finally disappeared and was changed to charge the host by the Micro USB interface on the ear card. Q5s can automatically identify the properties of the connected device. If it is a PC computer or other charger, it will turn on the charging mode and automatically adjust the charging current parameters. If the connected device is a mobile phone or player, it will stop taking power from the device. This is also one of the improvements I like Q5s.

In addition to the volume knob, professional players and decoders will integrate independent playback control keys to make it easier to switch tracks and pause playback. Q5s is certainly no exception.

Q5s is not big when you hold it in your hand. Its girth size is 124 × 64 × 16(mm) and its weight is about 195 grams, which is exactly the same as the previous generation Q5.

Q5s completely inherits the design of the previous work, including a gain adjustment lever, a subwoofer switch, a coaxial/fiber/Line in port and a Line Out port.

we know that the decoding chip of FiiO Q5 is two AK4490EN. this time, Q5s is upgraded to two AK4493EQ channels. the left and right channels are processed by one decoding chip. the advantages are low sound distortion and better signal-to-noise ratio. At present, the portable high-end audio playback products are all equipped with dual decoding chips, except for the chip model. As for Q5 and Q5s, they are both top-level decoding chips, and the difference lies only in the details.

In terms of decoding performance, due to the blessing of XMOS XUF208, Q5s supports up to 32bit/768KHz PCM and direct hardware decoding in DSD format. Optical fiber input supports up to 24bit/192KHz PCM decoding. In Bluetooth, LDAC encoding supports up to 24bit/96KHz decoding and coaxial input supports up to 24bit/192KHz decoding. When connecting a computer as a USB DAC, it supports 24bit/96KHz PCM decoding even if the driver is not installed, and the performance is very powerful.

Q5s is very exquisite. It adopts a fever-level audio power supply circuit, in which the analog part, digital part and signal amplification all adopt independent power supply to avoid mutual signal interference and ensure the purity of sound.

In terms of battery life, both USB decoding and Bluetooth decoding are longer than 9 hours, while if you use line input, the battery life is longer than 25 hours. In addition, after the system is idle for 10 minutes, it will automatically enter the standby power saving mode.

Q5s uses two OPA1642, and the signal amplification uses the combination of AD8620 + OPA926. Bluetooth uses Qualcomm CSR8675 Bluetooth chip, supports Bluetooth 5.0 protocol, supports AAC, AptX, AptX-HD, AptX Low, LDAC, HWA, etc., and achieves full format Bluetooth decoding.

3.5mm output port when connected to 16 ohm impedance earphones can reach 220mW, the balanced output power under the same impedance can reach 560mW, and the signal-to-noise ratio is greater than 115dB. Q5s supports headphones with maximum 150 ohm (3.5mm) and 300 ohm (2.5mm) impedance.

its sound quality comes down in one continuous line with Q5, the high frequency tends to be flat without turning on the gain, but if FiiO's FH7 earphone is replaced, it is just the right kind, so Q5s still needs to pay attention to when matching earphones. I tried 3.5mm single-ended and 2.5mm balance respectively, and I can obviously feel that the quality of the 2.5mm balance port is better, the timbre is more positive, the reduction is the most accurate, and the control force is higher. The timbre of the single-ended interface is more audible and the ears are not easy to get tired, but compared with the 2.5mm interface, there is a lack of stimulation.

is used with FH5 headphones, the opening gain and BASS switch have the best hearing feeling. The first ear feels excellent quality, the intermediate frequency is especially smooth, the bass even has the feeling of listening to the box, which is very strong, and the horizontal sound field is very wide, and the space atmosphere is first-class. However, after changing to FH7, BASS and gain will have to be turned off. I feel that the adjustment of 2.5mm port is extremely advanced. If I turn on the high frequency, it will be too much.

I showed it to my colleague and listened to the combination of Q5s + FH7. The front end used iPhone and the genuine lossless FLAC format of QQ music download. He only listened to it for more than ten seconds and asked me: Has Apple's sound quality become so NB now? Or is your earphone very NB? I didn't know how to answer at the moment.

, as a mobile phone music party, FiiO Q5 or Q5s is the simplest way to obtain HiFi sound quality. Especially for iPhone phones with 3.5mm earphone port cut off, Q5s is very necessary. It can not only provide excellent sound quality, but also has too many functions. Connecting a Macbook or PC can be used as a high-quality external sound card, and connecting a mobile phone can be used as a high-quality decoding earphone, even the Bluetooth wireless connection is many times better than the all-in-one Bluetooth headset.

, if you already have a decoding ear with such qualities as Q5, then there is no need to update it. Although Q5s has a better experience, there is not much improvement in sound. Moreover, I also looked at the price and brought an S price to an extra 300 yuan. Considering the improvement and improvement in the product, this 300 yuan is worth it. Therefore, fans who do not have Q5 can consider the new Q5s.
