This article is a translation of the following Japanese article.

The model to be covered this time is the SONY WF-XB700. I think it's impossible to explain about SONY anymore, but it is one of the top audio brands representing Japan or the world, and it is a prestigious audio company that continues to deliver extremely high-quality audio products to the world.

 

The Sony WF-XB700 is a deep bass model that Sony has proudly launched into the world.

Basic specifications

  • Continuous / maximum playback time: 9h / 18h
  • Waterproof performance: IPX4
  • Supporting codec: AAC / SBC

 

 

Unboxing

The overall design of the earphone package is fairly standard at the SONY package at this price range. Accessories are ear tips, charging case, charging cable (Type-C), and instructions.

 

The earphone case has a slightly plastic feel and emphasizes sportyness and casualness, but the transparent part is processed like frosted glass, and it is rather elaborate. Rather, it is a rather stylish design that disguises itself as a cheap feeling.

Fit

The fit is very good. At first glance, you might think that it has a weird-shaped weird shape, but because the nozzle area is well made, it does not come into a weird position even if you fit it loosely, and you can easily realize a solid wearing feeling.

Connectivity

Quite excellent in the price range. I don't know well because I haven't been to a crowded place, but it's good at home. It also has excellent distance resistance, and it is seamless and undisturbed even at a distance of 5m. Even if there is a shield, it will connect without problems.

 

I think there is almost no white noise.

First of all, it's not clear why my earphones have explicit left-right differences in the deep low end. I repeatedly considered the possibility of measurement failure and changed the measurement location in consideration of the feeling of wearing and the possibility of environmental noise unique to the location, but this left-right difference does not disappear. The reason for its occurrence is a mystery and it is mysterious at the moment, but I will post it as it is.

 

The package of this earphone says "Achieves overwhelmingly heavy bass and clear vocals", but as you can see, the sound design is rather straightforward and aims to achieve that claim. It can be imagined that the bass and vocal range are emphasized, and the mid and high range has a rather natural luster, and the high range is somewhat flashy. The balance is close to flat, except for the explicit ridges in the deep bass, and it seems that the pitch is adjusted very carefully so that the deep bass does not affect the natural feeling in the midrange. It's a typical warm sound.

Those who bought this earphone thinking it was a rugged heavy bass model may be surprised that the sound field is relatively bright. Frankly speaking, the midrange is fairly rich to make the vocals look nice, without the cramps typical of low-end models, and vocals sound really clear and close to natural. There is not much dry feeling that is often found in V-shaped, the mid and high frequencies are quite lively, the coloring in the high frequencies is not bad, and the high hat splashes that disturb the vocals do not become annoying, so we can convinced by the phrase "clear vocal".

 

The problem is the "overwhelmingly heavy low range", which is actually emphasized in the deep part, but because of the acoustic design considering the mid range, the presence of the low range is Not noticeable. Therefore, it is true that the heavy bass sounds are brought out when you listen to rock music with heavy low frequencies, but the low frequencies do not have a significant presence in general songs. The people who usually listen to the rugged low frequencies and the bristle bass sounds, the more they would like to ask, "Where is this suitable for heavy bass model?" Rather, many people may feel that it is a tight low range rather than a thick sound that the word “quantity” can imagine.

 

That's why I'm not used to low-frequency models, it's nice to hear with an interest what a normal listener is like, but a person who is a low-range junky may make an unsatisfied sound. Also, I think it's a pretty good earphone for listeners who enjoy the heavy low-range and mid-range transparency in deep places like EDM.

Final verdict

Comprehensive evaluation: ★★★★

We recommend it as a low-end model introductory machine. While maintaining the natural midrange atmosphere with a high vocal focus, the presence of the deep low range is added, the usual music is a little deep, warm and warm, and it is adjusted so that it sounds crisp. Well, it's for everyone. In addition, the tight, stylish deep low range and the clear midrange of electronic sound are good with EDM. However, if you listen to it as a heavy low range model and expect a rugged low range, it is basically a tight and elegant low range, so you will feel that it is too elegant. In fact, I wanted to hear more funky bass.

 

The quality is high as a whole, the specifications and communication quality are sufficient, and it is an excellent earphone in this price range.
