Since the HIFI market blowout in 2016, more and more player products have sprung up like bamboo shoots after a spring rain. Major manufacturers have worked their best to develop their own product lines, from traditional heavy "plank bricks" to portable earphones "explosive bags", and even the popular Bluetooth decoding player "small clip" and mobile phone external portable player "small tail" in the past two years. The appearance of the small tail has squeezed the market for entry-level portable players to a certain extent. In terms of product positioning, today's protagonist Fiio M3 Pro, like its predecessor M3, is mainly aimed at students in school. As a student player, can M3 Pro have a place in the player market? Let's find out.
Unpacking and Appearance
box is the player's effect diagram, Fiio's logo and the small gold logo in the upper right corner (there have been small gold labels for everything in recent years), and below is the model, M3 pro.

are the words parameter information and manufacturer information.

box is drawer type, and the player body can be seen directly when pulled out. The small box below is the accessory area.

A list of all accessories, including the player body, warranty card and instructions, and a typec data cable

player is a whole glass cover plate, equipped with a 340*800 3.5-inch IPS screen, adopting a full screen design, and the whole front is almost a screen (the border is skipped). Compared with the price is similarM5 series, the screen is not a little bit bigger. It is worth mentioning that the M3 Pro front was pre-pasted with a screen protector at the beginning, eliminating the trouble of looking for a film.

screen is also made of glass cover plate, which is very beautiful. The film is also pasted in advance. The charging power is indicated below. Although 5V1A is very small, fortunately, the battery of the player itself is not large, which is not satisfactory.

From left to right at the bottom of the player, you can select a microphone, a typec interface, and a headphone interface. The headphone interface supports multiplexing. You can select PO or LO.

The left side of the player is the button and the TF card extension interface. The M3 Pro body has no storage space and needs to be used with the TF card extension. The key sequence is: power supply, volume +, play/pause, volume-, where there are bumps on the play key, which is convenient for blind operation.

Summary: The appearance of M3 pro is relatively calm and low-key. The opening and buttons of the whole machine are concentrated on the left and bottom, which is convenient for one-handed operation and suitable for students. The whole machine has a quality of 67.6g, light and small. The front and back of the all-glass cover plate is also in line with the current aesthetic, and the factory pre-film is very considerate. The fly in the ointment is that there is no protective cover attached, which has not been found on the official website.
sound quality
player is naturally to listen to music. Fiio M3 Pro, as a student player, is quite satisfactory in sound quality performance, mainly for earplugs and some easy-to-push big ears. The thrust is not big but it is in harmony with the analytical force. Thanks to ESS Sabre ES9218P decoding, there is no discount on player fluency when playing HIRES audio files. Support PCM sampling rate 384kHz/32bit, DSD128(5.6MHz/1bit), support MP3WMA/APE/FLAC/ALAC/WAV/DSD and other comprehensive audio format playback, output power ≥ 75mW(32 Ω/THD + N<1%), signal-to-noise ratio 117dB, bottom noise <2uV. Using Taylor Swift's "Lover" as the test track, after a certain period of audition, I feel that the sound is low and very clean. The overall sound dye is less, and it is among the best at the player level below 1,000 yuan, and it wins in comparison with its own M5 and BTR3. The price/performance ratio is very outstanding.

recommend low-resistance and easy-to-push moving coil headphones and moving iron headphones for matching headphones. After testing, when used with Faudio Major, there was a lack of thrust. However, Major itself needs higher thrust to drive, and insufficient thrust is understandable. When matched with earphones that do not eat thrust, such as se535,Fiio F9 Pro and other earphones, the overall hearing feeling is very full, and the analytical power and thrust of the player complement the earphones. It is worth noting that the earphone interface of M3 Pro can be used as Line out interface, and can be externally connected with earphone equipment to enhance thrust.

Endurance
After a month of actual measurement, thanks to the excellent power consumption control of Junzheng X1000E main control and the large battery brought by the larger body, Fiio M3 Pro has a very strong endurance. The 60% volume can be played continuously for more than 11 hours (flac,16bit) and can be fully charged after 2-3 hours (5V1A). As a student player, it can satisfy students' daily use.
function
as a student player, M3 Pro is very powerful. The playback function supports A- B repetition, which is very convenient for listening to English. Fiio's thinking for students is very clear. Apart from repetition, the commonly used function is calculator. Students can easily calculate in class, which is helpful for learning.

is e-books. M3 Pro supports storing e-books of TXT text into the designated directory for reading. Of course, you can save the novel for reading (er, hey).

students sometimes record the teacher's lecture recording during class to facilitate review, the recording function of M3 Pro can be perfectly qualified for this. The recording duration depends on the size of the memory card. When using 64G TF card for storage, it can easily record more than 800 hours of audio.

In addition to the above, other small functions include the picture viewer. Although the screen resolution of M3 Pro is limited, Fiio still adds a picture viewer function (M5 does not). However, there is no zoom function and needs to be strengthened.

The function of M3 Pro in audio playback is also remarkable. USB can select digital output. At this time, the player is equivalent to a digital turntable and can be connected to an external decoding ear to improve sound quality. The notification USB function can also be used as an external sound card to improve the sound quality of computers and other devices. The fly in the ointment is that the M3 Pro does not have Bluetooth function, and it can neither be used as a Bluetooth receiver nor a Bluetooth headset (M5 can). However, students do not have mobile phones, and Bluetooth is not a big problem.
summary
Fiio M3 Pro, as an entry-level student player, has done a very good job in music playing, and has also added many practical small functions. The target group is directed at the students. Breaking the long-standing public impression of "simple, crude, low-cost, low-quality" student players. In terms of appearance, battery life, sound quality and function, it is much stronger than the players at the same price on the market. It not only took over the baton of the predecessor M3 and continued to break out of the world in the low-end player market, but also went further and better attracted the target group through more intimate and practical functions, which can be described as a "student party weapon". Thank Fiio for providing such excellent products. At the same time, I hope Fiio can make persistent efforts and do better and better!
