Disassembly Report: FiiO Feiao M3 Pro Portable Lossless Music Player
speaking of music players, many people may say that this is an outdated product, and there may also be many post-90s like Xiaobian who begin to recall their previous lives. Xiao Bian also vaguely remembers that my first MP3 was allowed to be purchased by my parents on the pretext of learning English listening. The era of MP3 is just like our youth, fleeting in the pan. In less than a few years, all functions have been replaced by fully integrated mobile phones.
, in today's market, MP3 products have begun to serve minority groups. The small body, professional sound quality, and the addition of new functions are deeply loved by music lovers and fitness athletes. Today, I love audio network to bring you such a product -- FiiO feiao M3 Pro portable lossless music player.

3. I Love Audio Network Summary
FiiO Feiao M3 Pro adopts square appearance, pure black integrated body color matching and frosted texture in appearance design. The weight of 70 grams in the hand is so small, light and comfortable to hold compared to today's "half a kilo" mobile phone. Sports, fitness, entertainment, whether in the hand or in the pocket, there is no obvious sense of weight. The front 3.5-inch full-fit screen has a resolution of 800*340 and supports touch operation, thus improving the human-computer interaction experience.
on the internal structure, the L-shaped single motherboard is clean and neat, the electronic devices are clear and clear, and efforts have been made to protect the devices. In terms of circuit, FiiO Feiao M3 Pro adopts Junzheng X1000E master control scheme with integrated audio codec, voice trigger and 64MB LPDDR, with low power consumption and smooth operation. High-performance DAC decoding chip is ES9218P to support audio playback in various formats. As well as Xinzhihui AXP192 power supply solution, Weian WP3881 Type-C input overvoltage protection switch to ensure safe use.
let's talk about the fact that there is no storage space in the main body and external memory cards. Xiaobian thinks that, first of all, canceling the storage space in the machine is a move to reduce the cost, giving benefits to users and lowering the purchase threshold. In addition, most mobile phones now no longer support memory cards, and everyone has free memory cards. When they are used, there is no need to invest repeatedly, make the best use of everything and avoid. ,
