Dealing the issues of the WF-1000XM3 era one by one

The previous model "WF-1000XM3" has requested that the case, the size of the main unit, the microphone performance, the codec, waterproof performance, etc. of the case, the body size, the codec, waterproof performance, etc. are requested.It can be said that this XM4 responded to all of these requests.

In particular, the compactness of the case is so different that it can be mistaken than when it was XM3!He is independent (XM3 did not become independent), LED lighting is dynamic and a good finish.The magnet on the case itself was quite powerful, and there was no need to worry about the earphones falling when taking out or storage.I feel too strong.

The XM4 is equipped with four microphones and uses high -precision voice -up technology.With two types of beamforming technology and bone conduction sensor, the speaker's voice is accurately caught.Even if you talk from an environment where the subway is too much, you can make noise calls as if you were talking from your bedroom.I can't really hear noise.

A feed -forward microphone that picks up noise and voice with metal design.It is an iconic part of XM4 and a collection of Sony technology.It looks delicate, but the drip -proof performance of the main unit is IPX4.The battery is 8 hours and a charging case 16 hours.

There is another microphone at the top, and there are various sensors here.

And there is a feedback microphone inside.The sound entering from these microphones is processed in the comprehensive processor V1.The sound is the A/D converter in the microphone → the V1 processor → DSP → D/A converter, and eventually vibrates a 6mm dynamic driver.With the improvement of the processing speed of this V1 processor part, the accuracy of Noikan has been improved.

At this time, the number of people who use wireless earphones as microphones due to telework demand has increased.Anywhere in the XM4 microphone, you will be able to deliver your voice more clearly.If you think, "It's easy to hear that person's voice," may it be a good impression in terms of work?

Achieves a more accurate wearing feeling

As mentioned in the reviews so far, XM4 has a unique earpiece.I tried shooting as much as possible, can you see the texture of polyurethane?Although it is urethane, it is not as sponge as complicated, and according to Gizmodo, the durability is about the same as the life of the earphone.Great!

In order to enjoy the true value of earphones, it is also important to wear it correctly.The application "Headphone Connect" allows you to test the earpiece.It is a function that is also in AirPods Pro.

I dared to put it on the right side (R side) and put it on, but it seems to be well aware.You can also compare the size of the earpiece, and if you do the installation test while changing two types from the earpieces of S, M, L, it will tell you which earpiece is better.I usually use M size earpieces, but I recommended S.

I feel that the installation itself is smarter than XM3.When I picked the microphone part and the upper part and twisted it into my ears, I was able to fitt in the same position every time.There is no need to find a sweet spot every time you wear it.The fitting is definitely evolving.

Change the cafe, the train, the home, and the audio room

Originally, Noi Can was effective for low -pitched noise like trains and airplanes, but was not good at making a high -quality sound like a female voice.Active Noikan achieves silence by hitting the sound of the opposite phase against the sounding sound, but the high sound = high frequency is fast, and the generating the reverse phase sign is not in time.

The XM4 V1 processor has improved significantly by improving the processing speed.In addition to the conventional bass noise, no -cans from the midrange to the high range, such as a human speaking voice, are improved.I felt that the cancellation was clearly different from the conventional no -can wireless.

When I tried it with Komeda Coffee, I could almost hear the conversation on the table over 3 meters, as well as the noise.You can hear some, but compared to your own AirPods Pro and Jabra Elite 75T, the volume is much more narrowed.The bass noise has been greatly cut, and if the tranquility of Noi Can so far is "Sue ...", XM4 is always sounding the sound itself that makes you want to express it as "...".。

The place where bass noise like stations and trains overflows is exactly what XM4 is good at.If you are on a train or bus, you will cut not only the engine sound but also the sound of vibration and the rubbing sound, so you can feel the illusion as if you mute the world itself, including yourself.As you can see, you can hear the announcement, but there is no doubt that the silence is a stepping -up that is one step in the recent no -can performance.A mysterious feeling that the body shakes but cannot hear the sound.

The accuracy of the outer sound capture (ambient mode) is high, and there is no discomfort.It may be that the good performance of the microphone is working.You can adjust the level of external sound import from the app.If it is set to 0, it will be about the amount of weak no -can, so if you are worried because the noikan is too quiet, it may be better to adjust it by incorporating the external sound.

The app can also be set from the app, such as equalizer, reduction of wind noise, and Speak to Chat (when you start talking at noikan ON), you can automatically import external sounds.If you use no -can on a windy day, you will get a loud noise like "goo", but if you turn on the wind noise, it will be reduced.It is not so much improved, and there is no change when the wind is reasonably strong.It seems that the feed forward microphone is automatically turned off.

The sound quality is outstanding.In particular, I feel euphoria in the middle -high notes of female vocals and pianos.I feel that the noise has been reduced, and the slopes of the sounds that had been buried in the noise until now were heard.I think I want a little more bass, but it can be improved with equalizer.The details of the sound are felt as a whole, and the vibration of the driver is not so crisp and can afford.Thanks to that, I thought that even if I adjusted it with an equalizer, I could afford how to sound.

The XM4 supports Sony's unique high -quality codec LDAC (supported codec is SBC, AAC, LDAC), and if you can play LDAC, you can enjoy 96kHz/24bit high -resolution sound quality wirelessly.However, the iPhone is not compatible.You can use "DSEE EXTREME", which has evolved the high -quality technology "DSEE HX" implemented in XM3, but if you think how effective this kind of upscaling is, on and off so that you can see it in a blind test.I felt the difference.You can feel more dynamics, and you can see small and high sounds.It depends on the compatibility with the song, but basically you can turn it on.

Is there any weakness?

Sound quality, no -can, size, design.There is no doubt that it is a high score no matter which one you take.However, there is no fact that there is no concern, but there is few functions that can be assigned to a touch sensor first.

The assigned function is preset for each set, so you can't customize it yourself.If you assign the right to the right and the left to the Noikan on the left, you will not be able to operate the volume.It would have been perfect if the volume was assigned to the long press and double tap on the left.

The other is about the wearing feeling.When I kept it for about an hour and a half, I felt pressure on my ears (where the pierced tragas open).The XM4 fits the body pushed into the ear hole with the ears, so it seems to be powerful here.

Although the feeling of wearing the earphone is a large individual difference, the XM3 has a structure that supports 3 points, while the XM4 is designed to increase the contact surface.Thanks to that, the sense of stability and sound insulation has improved, but at the same time, I feel that the power to be applied to the ear has increased.Well, if you get tired, let's remove it a little and rest your ears.

The rest is about the codec, but I think a bit about the use of AptX and adopting LDAC.Now that many Android smartphones have LDACs, so honestly, there is no particular taste to balance with APTX.There are some disadvantages from the wireless audio fans who have the APTX environment, but do you want to focus on LDAC?

Eco package, this is good

The XM4 package uses a sustainable paper material "Original Blend Material" developed by Sony.Thanks to that, the whole package is very compact.Good earphones are in a big case, but isn't it troublesome to throw them away?

This package is not such a thing, and it is easy to disassemble and throw trash.The texture of the paper material and the texture of embossing are also good.It is better to store only the included earpieces in something like a small bag.It may come when you need a different size.

The next wireless earphone competition begins here

Sony has always led the industry.Just like XM3, this WF-1000XM4 has also distributed the current wireless earphone industry at the moment due to sound quality and no-can performance.In the latter half of 2019, as the AIRPODS PRO no Can was told as a benchmark, the XM4 no -can will be described in the future.

If you think about it, the AirPods Pro has a lot of design and no -can performance for iOS users, but it was not a sound quality suitable for nearly 30,000 yen, my impression.In the first place, the sound quality has a limit at the time of wireless, and its division is inevitable.I always thought so.

However, I felt that XM4 has exceeded the limit of wireless sound quality.After all, noikan performance was made to break through the limit.

In other words, there is a sound that can only be heard because of the overwhelming silence of XM4, and that is the sound that has been reached thanks to Neikan.Perhaps because of the overwhelming silence, you may have noticed a fine change due to upscaling like DSEE EXTREME.XM4 has raised the sound quality level of wireless earphones by noikan!

The word "good sound" has a lot of meaning, but WF-1000XM4 has the power to make this place only for music and yourself.Because it is tranquil, you can hear more music than before.Noi Can Wireless I'm here and there is no choice but to say that.
