Von Timo of HiFi, Feiao Watch HiFi Player M5 Evaluation

in the traditional impression, the better the sound quality of the player, the larger the size of the player, and there was a time when if you were not holding a "brick" player, you were embarrassed to say that you were playing with HiFi. With the passage of time, players have gradually begun to return to rationality. Although brick-style products are still not in groups, small and high-quality players have emerged, and some brick players have begun to launch Mini versions.

in terms of volume, M5 is definitely the smallest player in Feiao. Its birth is quite dramatic. According to Matt's introduction at Feiao's spring new product launch conference, at first the engineer just wanted to create a Bluetooth decoding earpiece as an upgraded version of BTR3, but the more function, the stronger the performance. Later, he simply added a screen and then changed the appearance and shape, which became the appearance we see today.

to make a square shape is also to lean on wearable products. M5 is a mini HiFi music player, a full-function Bluetooth decoding ear player, or a watch with step recording and recording functions (used with strap accessories). You are not wrong, it does support recording function. Music lovers born in the 80s should have a lot of feelings about the recording function. When Senior high school, they never used MP3 to record the teacher's lectures.

is small in size, it has also passed Hi-Res dual certification, including Hi-Res Audio and Hi-Res Audio Wireless certification. At first I thought the body of Feiao M5 was made of plastic because it was too light and the metal texture was not strong. Later, it was found that the whole middle frame was made of metal and was a whole, which was processed by CNC. The front and rear panels are all glass, and the materials used are still very real.

, there are very few keys on the M5 body. The three mechanical keys are the power switch key and the volume adjustment key. At both ends of the volume key, we can also see the two built-in microphones on the M5. In addition, its earphone interface is 3.5mm standard, and the interface can also output in Line Out or coaxial mode.

is the Type-C interface and the TF card expansion slot. Like most players in Feiao, the M5 has no built-in storage space and must be plugged in to use. All music files are stored on the TF card. M5 supports TFC cards with a maximum capacity of 2TB, which is absolutely enough, no matter what kind of enthusiast you are.

the main machine is very small in size, with a circumference of only 45.3 × 42 × 13.7(mm) and a weight of only 38 grams.

M5 has a small display screen, only 1.54 inches, but the resolution reaches 240 × 240 pixels, so the display effect is clear. In addition, it is made of IPS material, so it has excellent visual angle and bright color performance.

M5 on Bluetooth hardware uses Qualcomm CSR8675 chip, which can support two-way Bluetooth transmission and lossless Bluetooth audio. With dual microphones, Bluetooth voice calls can also be made when used as Bluetooth decoding earphones. That is to say, after connecting it to its own mobile phone, it can not only listen to music, but also answer or make calls at the same time.

's initial product project is a top-level portable Bluetooth decoding earpiece, so Bluetooth performance is bound to be powerful. M5 can receive almost all Bluetooth audio formats, including SBC, AAC, Apt-X, Apt-X HD, LDAC, etc., and can also emit SBC and LDAC Bluetooth signals.

to imagine that a small player like M5 has a deep standby capability of more than 22 days. All this is due to its ultra-low power consumption main control chip, Junzheng X1000E. Friends who have experienced the ups and downs of the tablet industry should be familiar with this main control chip, and it can be regarded as an evergreen tree. After so many years, it still performs well after being refined and simple.

M5 is based on Linux, so there is no stuck problem like Android. Its power management chip is AXP192, which is also an old power chip with excellent performance and stable operation. Under this power management chip and 550mAH built-in lithium battery, M5 has 10 hours of local music playback capability or 13 hours of Bluetooth playback capability, of which Bluetooth standby can reach up to 100 hours.

there is such a back clip accessory in the M5 packing box, which can easily clip M5 on the bag belt or collar. If you want to wear it on your arm, you need to purchase additional strap accessories.

This official silicone strap is made of food-grade silicone material, which has a first-class touch, but a little love of dust. In addition, after wearing the strap, I always feel that the color value of M5 has dropped, which is not as good as when it is naked.

Feiao's products have always had comprehensive functions, and M5 is no exception. It also supports USB Audio and USB DAC functions, and can solve up to 32bit/384KHz PCM and DSD128 specifications, of which DSD supports DoP and D2P processing methods. If connected to an Apple MAC computer, the USB DAC can work directly without even a driver. In addition, if a device such as a U disk is connected, M5 can directly read music files from it, which is really rich in functions.

M5 is AK4377. This model must have been used to enthusiasts. Its power consumption is not high, but its performance is excellent. It supports full format audio decoding, DSD format hardware decoding, and CUE has no problem at all.

When driving 16 ohm impedance headphones, the maximum output power of M5 can reach 42mW, which can adapt to all headphones from 16 ohm to 100 ohm impedance, so many times we really can't judge performance by volume.

M5 did not disappoint me in terms of sound quality, and there were even some surprises. Perhaps because my expectation of it was not high at first, after all, I had heard of AK4377 mobile phone products before, but the sound quality of M5 is different from that of mobile phones with the same type of decoding chip. The feeling of the first ear is abundant energy and details, and it can reach M9. Using wired headphones to listen, M5 has thick intermediate frequency, excellent low frequency texture, and high frequency is not as bright as M9, but it is more real and correspondingly more resistant to listening. Its sound field is quite regular, the three-frequency connection is natural and smooth, the sound dye is very few, even a little plain boiled water, and the sound color has a charming feeling when matched with the moving iron earphone with slight sound dye. Compared with the M11 player in hand, M5 lacks control, after all, the price is here.

sound quality. Considering the size of M5 and its selling price, there is really nothing to be picky about. However, I think there is still a lot of room for improvement, that is, the operation mode of M5 and the response speed of the system. I feel that I still need to continue to optimize. I also look forward to the subsequent firmware update.

at the end of this text, I naturally remembered singer Von Timo, whose small body contains such huge energy. M5 seems to be the von Timo of the HiFi world......
