I have bought 8 MP3 (of course, only one of their own, the other is a gift, some of the time for others to buy), from my own feelings, I recommend three brands: Meizu (I use is ME, bought in 2005, and now have not been bad), Blue Devil, Ai Nuo, Taito, do not recommend the Ubiquitous, Newman, Tsinghua Ziguang. Patriot and OPPO do not have to consider, the price is too expensive. Those less familiar and cheaper brands, don't even think about it, many of them are just raking in the dough, I've seen it all too often.
My own experience in choosing MP3:
1, first of all, the performance, features, appearance of a ranking, to see their most important which, the least important which, purposeful to choose.
2, in product quality, look at the details of the workmanship, such as whether the seams match closely, whether the screws of the cross heart in the center, the specifications of the screws, tighten the degree of whether they are the same, pinch the shell to see whether the material is thick.
3, but also to see whether the three serial numbers are complete, generally one on the packaging, a warranty card, MP3 body on one. Like the patriot in this regard is doing a good job, are printed and pasted on, even on the warranty card are not handwritten.
4, see how many accessories in the package (generally speaking, the more the better, small-cost operation of the manufacturer will not come with a lot of accessories). Like my ME, the accessories are USB cable, USB adapter, plastic sleeve, cloth bag, lanyard, CD-ROM, all of which are individually wrapped in plastic, and the headphones come with a sponge sleeve, which is quite complete.
5, absolutely do not choose the headphone cable and lanyard together, that workmanship is very rough. Good brand will never save cost on this.
6, do not listen to JS blowing sky-high, what he said do not believe. We only believe in data. Turn the product manual (generally in the last page), look at the product performance parameters, focusing on signal-to-noise ratio, distortion, headset power. Generally speaking, the more complete the parameters, the better. Signal-to-noise ratio is now at least 85dB or more, below 80dB is simply abusive to their ears. Headset maximum support power to 5mW * 2 or more, 10mW * 2 is better.
7, look at the packaging is exquisite, manuals, warranty cards, certificates of good paper, printing is clear. Good manufacturers are not sloppy in these details.
8, go to the online forum bubble, look at the netizens of the evaluation, especially after the use of the evaluation of the machine, it is very informative. If any product is scolded more than others, you have to think about it.
9, if you have time, to see the brand's after-sales service points. Because now is the dealer only care about selling, the repair dealer only care about repairing. And because there is no direct profit relationship between the consumer and the repairer, sometimes you can hear some things that you can't hear outside.
Now many claim to be MP4, or even MP5, in fact, just color screen MP3, is in the original MP3 on the increase of a color screen and the corresponding function. To be honest, the current MP4 screen is generally 2.4 inches, 2.8 inches, the resolution is generally 360 * 240, such a screen to see a long time eye strain. Moreover, many MP3s do not support DivX encoding (so they can't really be called MP4), so you have to convert the format on your computer, and it takes almost 1.5 hours to convert a 2-hour movie, so you won't be interested in playing it after a few times. So, I suggest you buy a real MP3, the former Phantom X3 is really a classic model, Philips 0102 decoder chip, but unfortunately it has been off the market. Now there are two more real, Blue Magic V7 and Taito X19, SigmaTel 3710 chip.
