[Ma Cang mercy's big Yan magic account] Let Ma Cang mercy roar past completely wireless! "focus on musicality" five eye-catching models-AV Watch

The full wireless earphone (TWS) product genre brought by Apple, which has set up various new common sense in digital life, quickly became one of the centralities in the audio industry.

Mr. Asakura says that TWS, which is transmitted by Bluetooth, did not stand in the context in the context of the sound quality, but came here and not only convenient but also sound.TWS, it's finally interesting for audio hobbies.

-There is a nationwide emergency declaration in May, and society has begun to shift to a phase that regains everyday life.In this Enma book, we will feature a full wireless earphone (TWS) genre in this Enma book, as it is music to accompany you.

Asakura: Looking back, I never picked up a complete wireless (TWS) itself in this corner.TWS has a great presence in the market, but portable audio has been small from a wired headphone to a wired earphone, and has come here to evolve a wireless and "perfect" wireless.In addition, there are many noise canceling functions that seem to have emphasized walking around the city.It will not be necessary to take this as an Enma book that emphasizes trends.So, this time, I ordered about 3 types of selling TWS products and listened to the sound.

The first thing you need to check is that "TWS has strict sound conditions."Since the small and light feeling of wearing is a selling genre, the diameter of the diaphragm (diaphragm) cannot be used, and the 10mm diameter can be easily used even at the same time.What is this point fundamentally about the reproducibility of the sound?

In connection with this, the housing must be packed considerably, and the way of catching the chamber (air room) is quite different from the past.Due to the battery duration problem, the power supply, which is an important factor that makes a sound, cannot be enhanced.The biggest problem is that the bluetooth compression format is the standard.No matter how much APTX is, there is no difference in compression of the source.

In this way, TWS is a genre with a lot of difficulty in the audio design.It is still convenient to subtract those problems, so it is a hot selling.The biggest dissatisfaction point in earphones/headphone listening, "the wire clings" is particularly large.

Audio has always followed the history that convenience and sounds are inversely proportional and have to make two.Whether you are stationary or portable, it is always in the world that the sound becomes neglected as pursuing convenience.There may be manufacturers who are working hard in such difficulties.With such expectations, this time I came to the desire to feature the latest trends of audio.

Let's lightly touch on the audition environment.My player uses an OLED AQUOS smartphone with a portable version of Foobar2000.The sound sources are all high -resolution (although the sound is not high -resolution), and the carpenters "Yesterday Once More" to listen to the vocals first.Karen and Richard harmony, and points such as the texture and thickness of the instrument are the highlights.

I also listened to "Mozart; Symphony No. 41" Jupiter ", performed by Ogen Joffum, conducted by the Boston Symphony Orchestra from my standard reference sound source.It is a sound source that has been very popular with the compilation of "German Gramophone & Decca Selected by Reiji Asakura" announced last year.Even if you listen to the music purely, there are many performances, such as the scale of the orchestra, the way of details, and the overtone of the strings.

――When listening to TWS, I would like to not use the refinancing sound source, such as the subscription service and other non -possible compression sound sources.The idea is that "it will be compressed at the Bluetooth transmission stage anyway, and the sound will not change even if you use a compressed sound source."If you compare the same song and compare it, you can tell that the compression sound source (especially the subscription) is on the "noise) at the" everyone knows "level.Anyway, if you enjoy the song purely, these sound sources are not appropriate in the use of sound quality listening.

For reference, we recommend that you prepare non -compressed WAV sound sources ripped from CDs and high -resolution sound sources purchased and downloaded.

Asakura: Well, it's common for such a trivial place to be the true identity of discomfort, so don't overlook it.

First of all, there are three models: "RZ-S30W", "RZ-S50W", and "EAH-AZ70W" released by Panasonic.Panasonic, who has been quietly watching the TWS market, has been hitting the market with fullness.That's why I didn't say anyway, but I compared it with a "certain selling product" that has a high reputation for sales in the market and is treated as a reference.

By the way, the no -can performance is not covered by the evaluation this time.However, Panasonic's TWS has a reputation for being excellent.I listened to each model at the beginning of this year at the beginning of this year, but at that time I felt the goodness of Noikan, and I felt that the level was high.That's why I listened to Noi Can on this time.

Panasonic's keyword is "clearly clear".Put it out clearly and push it out to the details.This feeling is common to all models.The class between products is divided due to differences in texture and quality, but the differentiation due to this model number is wonderful, and the lineup grade and sound grade are wonderfully proportional.Marketter and technology are fused, manufacturing and quality induction are skillful, and the market segments are good at balancing with the prices desired.

――Speaking of which, the more you become a higher -ranking machine, the better the sound.It is easy to choose if it is easy to choose.

Asakura: Let's listen from "RZ-S30W".This is a strategy that expands the brand of the brand as an entry model.The "EAH-AZ70W" given by the technique brand is one different from the Panasonic brand, and the price is naturally given.However, in terms of cost and performance, the best-selling products are two models with Panasonic brands and "RZ-S50W".In that sense, it had a very marketing atmosphere.

Zubari, a completely different sound from the "some selling products" mentioned earlier.This is very impressive.There is no sense of resolution, but rather fluffy, and if anything, it feels like you can hear it with the amount of bass.On the other hand, this is obviously listening to high notes.Paradoxically, the bass is modest, and a clear, clear, crunchy feeling with a clear, clear, emphasis.I feel the feeling of being excited and energetic.

On the other hand, the bass is a little short, so the balance is in the middle and high range.Although there is a problem of bass, it sounds like a lot of information, so it will give you clear and clearly listening to the basic trend of "I want the amount of information" in the price range.。

At Yestday Once More, it is clear but a little vocal, and the harmony of the sound is hard.In Jupiter, there were high -rise and metallic places.Compared to the sound trends in the market, including this, and compared to "certain selling products", it can be determined that it is a model that incorporates the unique nature unique to Panasonic.

Asakura: Next is the middle model RZ-S50W.This is good at making Panasonic sounds.You can understand the grading properly, and you can feel the value of the model number from 30 and the high class.When the user considers the purchase, if you listen to the 30 entry model first, you will have the impression that it is like this.Then, if you listen to 50, it will be "Oh, it's pretty good."In this way, the difference from 30 is made, and the company's internal differentiation is given to chitin.I think that is the Panasonic TWS lineup that fuses such aim and marketing sound.

Speaking of sounds, the look is better than 30, and you can see what kind of sound in the sound field and how it sounds.Karen's vocals are very refreshing and have the characteristic that they are clear and relaxed.However, in 50, the emphasis fades and it is refreshing.This kind of fluffy feeling comes out of the high -frequency nobi.

If you say severe opinions, you will feel a little more sound.Karen's voice is good, but she wanted more clearness when she was with Richard.On the other hand, the impression that the surface of the sound has been beautifully polished, this polish feeling is a special point.30 was a coarse wax, but here the wax texture became smaller, and the shine also felt shiny and smooth.

I was quite impressed by the other song Jupiter.This performance has a bass and a second violin on the right channel, and the first violin is a classic two -wing arrangement of the left.I felt that the difference between the lube and treble on the left and right, the difference between the first violin and the second violin was better than 30.

However, it would be a little difficult to listen to the orchestra with this.The “specific selling product” emphasized the volume of the bass, but the sound of this product seems to be like an antithesis for this.As a result, the amount of bass is not enough.For carpenters, the formation is small, and the bass is about bass draga and bass, but if it becomes full orchestra like Jupiter, it is undeniable that there is a lack of acoustic bass.

However, the overtones of the first violin are common.This performance was very stable, and the American orchestra sounded more brilliant than Europe, but I felt that such a gorgeousness was out.

Asakura: Next is the technique brand "EAH-AZ70W".The lineup is a model number in 30, 50 and 20 steps, but when it comes to technics, the grade will be much higher.Impressively, it would be about 85 instead of "70".Technics brands are strictly different for audio enthusiasts against popular brand Panasonic.

Of course, the sound is also accounting for the brand concept, and Panasonic makes a popular sound, while technics aim for a full -fledged sound that enthusiasts are impressed.That is the first.In terms of products so far, even if I took one of the integrated audio like a boombox, the Panasonic brand was not as much as I could hear the sound creation with OEM.On the other hand, the OTTAVA S "SC-C50", which is made by technics seriously, has a much better sound due to advice from the Berlin Philharmonic.In that sense, TWS is also much different between 30/50, which sells the amount, and 70, which is both price and technically.

However, it is a pity that one does not contain a magnetic fluid driver.The driver, which was introduced on the high-end whafone "EAH-TZ700", was highly evaluated for low-frequency reproducibility.There is nothing to say that there is no.However, conversely, I would like to evaluate that "I made this sound so far without putting it in."

Regarding this product, the impression when I checked it on CES was "the degree of perfection" was not good.However, listening to the product model this time, the impression changed considerably.At the time of CES, there was a place like "Noikan is good but what about music?"

First of all, carpenters are highly transparent.Regarding the previous two models, there was the power and contours in the middle and high range, but it did not enter the transparency.The technique brand 70 is there.Transparency is an important point when listening to Karen's song, and the clear texture is also a characteristic of Karen's singing voice.

Another thing is that the fineness of the grain is also good.The lower model sells the energy that makes you listen clearly, so the coarse sounds look better.However, since the basic performance is improved, even if the vocals are further finer, the energy will not be lost.This is a clear advantage compared to the Panasonic brand.

Another thing, the stability of the bass was also good.This sound source creates a bass feeling with the bass drum and bass, but the sound of the bass draga is made to the lower model and the sound amount of information in the bass movement is much higher.It was good that the sound image, especially the vocal sound image, was located in the center, and the outline came out clearly.The two models of the Panasonic brand are basically "I'm going to go well!"On the other hand, the technics brand was clearly cleared and configured, the sense of position and stability of the sound image in the sound field, and they came out clearly without a sense of emphasis.In that sense, I feel that the vocabulary has increased.This would be the high resolution or the current market proposition.

What about Jupiter?In the past, the sound of the classic was like Paul Moria, and it felt like an electric.On the other hand, this product has an acoustic feel.There is also a grain, and there is a naturalness that is not an electric device.It is not just a gorgeousness, but calm and colorful.

If you place an order, you want to cut it into more details.It would have been better if each sound that made up the harmony when it became a ensemble.But it's different from the Panasonic brand.It is much different.It is a truly technique brand.Although it is clearly clear, it creates a sound world that is isolated, transparent, transparent, and transparent.I hope the texture can be improved further.

―― Well, can I be honest?I thought, "Do you add a" technique "brand to this sound?"I don't think it's a bad sound, but "I can't see the brand from the sound" and "there is no technique sound."In a sense, I have a romantic philosophy in a sense, but in that case, the brand is a condensed story, and in terms of technics, it supports Japanese audio and DJ music culture.In recent years, there should be a philosophy that has been accumulated over time, saying that he has been instructing the Berlin Philharmonic.

However, this sound did not see such a "story of technics".It is a technique brand in the world, not an unknown elephant that does not know any horse bones.I wanted you to see the brand history and background music culture from the sound.

Asakura: I see, I understand what Amano -kun think so.Certainly, the style of technics, the real feeling, the authenticness and the authenticity unique to technics, and the natural feeling were not so much felt, but in a sense, I thought it was technics.Isn't this an expansion of the brand concept to capture a new field called TWS?There is a feeling that I worked hard and it is better than the Panasonic brand, but I want a little more like a high -end feeling that music comes up naturally.

This is the point that the magnetic fluid driver mentioned earlier was good, and the original technique sound would be the Wired TZ700 using this driver.This area is difficult on TWS, and no matter how hard you try, it is difficult to output.
