Recommend a cost-effective MP3 player.

Your price of no more than 1000 won belongs to the price of high-end MP3 700~ 1500. This is the pinnacle of MP3. At present, MP3 at this price has basically ignored the chip, and the chip is rarely mentioned in the introduction. Because of this price, it is basically difficult to upgrade hardware equipment, mainly software. Various patented sound effects and power-saving technologies to restore the sound quality are actually the biggest features of MP3, which comes at a price. (In this regard, all domestic MP3 players can be erased, because domestic MP3 manufacturers basically have a large proportion of so-called sound quality chips. It is well known that OPPO always likes to use Philips chips, while Meizu borrows Samsung's 3D sound technology DNSE. The spritizer sound effect in its MINI was originally the DNSE sound effect on TP, which was developed by Samsung. Now the spritizer is only changed by Samsung. Generally speaking, Japanese sound quality is the first, among which Sony has been the first and second in recent years. Sony has too many technologies, such as sound quality restoration, external noise reduction, 3-point fast charging and special shell treatment. Low frequency and high frequency, but Sony's current machine is not very extensive in adjustment, not as good as South Korea's Audi I7. In this field, the key words related to sound quality are sound effect PCB working chip in turn. In this field, domestic products are almost extinct, and iriver, Audi, Sony and IPOD can often be seen abroad. Samsung Electronics .. If it is the most cost-effective MP3, then the price you give is 1000 yuan. The first choice for high quality performance is Dior I7 of iriver. I recommend Dior, but I don't recommend Samsung, because Samsung's technical hardware configuration can't keep up. Although there are thousands of MP3 players, I'm sorry about the price of thousands. As for iriver, they lack technology in the competition of high-end MP3 players. Basically, MP4 and I7 with large screens appear, and its biggest feature is that it can adjust the EQ setting of 5 segments. Users can also set BBE to make music sound clearer and more transparent, MP Enhancement can make up for the loss of music and sound in compression, 3D surround can improve the stereo effect, and because its overall three frequencies are very balanced, it is relatively simple to adjust. Because of the strong bass of this machine, it is unnecessary to consider suppressing the bass part when adjusting, and it is precisely because of its adjustability that the I7 can adapt to all kinds of music. In addition, its sound quality is better than that of iPod nano (comparative evaluation article /a/200708 10/000008.htm). The cruising volume is 25. When the screen is off, only the song I7 decoded by 128KBP can be played for about 50 hours. I7 supports not only MP3, WMA, OGG and WAV, but also FLAC, which is a very common lossless format in China. Its highest writing speed reaches 3530, while its highest reading speed reaches 6642. At the same time, I7 is a very fashionable machine, especially red. Its only drawback is that for thousands of MP3 players, some products of I7 are of different quality in some stores. At present, the price of I7 4G is between 900~ 1000. If you want to use it, I suggest saving some money to buy 8G. The other is Sony NW-S70XF series, (X stands for number, and the difference in numbers is only the capacity difference of 3: 1G5: 2G6: 4G), which was the king of flash MP3 sound quality in 2007. It is characterized by its outstanding sound quality, which has almost all the technical achievements made by Sony in music before 2007 and 2007. Including active noise reduction technology (that is, ignoring the noise of earplugs and reducing the external noise 1/4, which is suitable for noisy places such as buses) and clear bass technology. In particular, the clear bass technology makes the NW-S70XF series have a very strong bass, and the last one is the technology of charging for 3 minutes and listening for 3 hours. The format supports MP3/WMA/AAC/ATRAC, among which AAC is Sony's own lossless format. It is truly lossless CD-level sound quality (the bit rate of FLAC and APE lossless formats is between 800~ 1200, while CD is 1400, which is actually lossless when compressed, but it is lossless only because the human ear can hardly distinguish it), but Chinese songs appear in one format. Sound quality and function completely overwhelm I7. Its battery life is nearly 50 hours, and there are many accessories like iPod nano (note that these accessories naturally need to be purchased separately like iPod nano). The NWU3 base is used to charge it and realize the connection with other products. WMC-NWR 1, an accessory that realizes L-in (transcription) function, and WLA-NWB 1, a Bluetooth transmitter that realizes Bluetooth function (it needs a receiver for Bluetooth use), have many advantages, but they also have disadvantages. On the one hand, it is necessary to copy computer songs into MP3 by software, and on the other hand, the shell is easy to be scratched, so a protective cover is necessary. Third, there is basically no one at present. The price is more expensive, and the cost performance is not excellent. The price of 1000 yuan can only buy NW-S705F (2GB) at most. [At the same time, the sound quality is actually better than NW-S70XF, but Sony and NWZ-A8 16 4G, which are cheaper than NW-S70XF, are about 900. However, compared with NW-S70XF, this product does not support active noise reduction and rapid flushing, and it is a Chinese operation menu, and
