100 points Ask for a recommendation of about 400 MP3 with the best sound quality?

It's about 400, and it's a pain in the face.

If you just want to buy a new one, then it's very thoughtless, Avery and E30 take a look, don't spend so much, I've heard, it's okay.

But since you're looking for sound quality, it's still recommended that you go to Sony, but it's only 2 hands. Sony, Aiodi, Apple, Jianwu and other artifacts, these sound qualities can really feel good. Apple's sound quality at this price point is not good, so it is recommended that Sony, other brands do not feel very good at this price point.

You can add some money, less than 100, try to collect a 2-hand Sony A728 or S639, 639 may be more expensive, these two belong to Sony's mid-range products, I have used 728 myself, very good!! The sound rendering is good, the bass effect is good, and it is very tasteful. You can go to the 2-hand trading area of the i*** forum to receive this, a very authoritative forum.

If you don't have a lot of experience in online shopping, let your friends help, in fact, there are not so many pz, I often buy and sell 2 lots, and I haven't been fooled, I'm a student, hehe

I wish you a smooth ride, don't mind too much about 2 hands, a good sound is king!!

It's really hard to buy good sound quality at this price, but the best one to talk about 400 or so is the Sony B152

Iodi E2

Good sound quality Sony is king This is recognized But Sony is generally more expensive, second-hand can be But if possible, you have to trade in person, try the machine It is recommended to use A728 or S639 I wish you can find your beloved baby!

Sony's E463 or S754 are the first to be recommended for the following reasons:

2. The plug is relatively good. The plug of the e463 is EX083, which is an upgraded version of EX082, although the sound quality can meet the needs of most burns, if it is not too burning, you can not upgrade the earbuds. The plug of S754 is NC033, the quality is awesome, and it is invincible within 300 yuan.

3. The workmanship and service life are relatively good. The reputation of Sony Walkman for 30 years is not covered, although the workmanship in recent years is not as good as before, but it is still excellent.

**Relatively high.

APE and FLAC are not supported.

Secondly, I recommend Samsung's Q3, the sound is clear and natural, very clean, and very durable. The workmanship is also very good, the plug is OK, and it can not be changed.

It is recommended not to buy other machines, especially Philips and Avery and, not that they are bad, but there is no machine that meets your requirements at this price. Aioudi's i9The sound quality is okay and the workmanship is excellent, but the machine has too strong a plastic feeling and the feel is not good. The plug is a piece of garbage, ** a little high.

Hope it helps.

Aiodi i9 **Price: 700 fast free shipping, support double lossless, powerful tuning, really not covered, Sony S754 is not bad, but completely beyond your budget, and does not support lossless format.

Avery and E300, the advantages are: stylish appearance, ultra-thin body, very light volume, good sound quality, and fast speed! It's the fastest in the e-series!

**Moderate, support for extended memory. Around 500! Cons:

Sony NWZ-B152F Sony's don't need much,**Now about three hundred iAudio E2 is more individual, but the sound quality is much better than Apple's Avery and E150 (2G) Avery and the sound quality is recognized These three are good, it is recommended to consider it.

If you have this budget, you can go to the i*** jar to collect a Sony A815 816 or Samsung Q1 Q2 or something like that, and it's good to listen to popularity.
