Engadget Logo Japanese version of Engadget Sony "WF-1000XM4" wins private earphone championship | Best Buy 2021

I didn't do a lot of big shopping in 2021 because of the Korona-ka, but it's good to get it immediately after its release! There are some that I thought.

Sony's completely wireless earphone "WF-1000XM4" is one of them. I'm a regular user of AirPods Pro, but I feel that AirPods Pro is already over. Personally, I can say that I won the 2021 Private Earphone Championship.

It was the previous model "WF-1000XM3" which was touted as a masterpiece, but of course I listened to it and felt that it was quite good, but I did not want to use it personally. However, the "WF-1000XM4", which has been updated after more than two years, has almost all the problems of the previous work, such as a significantly smaller case and body, in addition to improvements such as long-awaited LDAC support and adoption of noise isolation earpieces. It has been resolved.

I think that the integrated processor "V1" installed in the WF-1000XM4 has improved the processing capacity, and overall there is less discomfort when canceling noise.

For example, in the previous model, noise cancellation was not effective depending on the environment (wind noise processing becomes noise on the contrary), but in WF-1000XM4, the canceling ability is weakened depending on the situation and it is unpleasant such as wind noise. I felt that it came to provide "comfort" comprehensively, such as cutting out the noise.

The effect of noise cancellation itself is natural, and by combining it with a new ear tip with high sound insulation, you can get a music environment that is quite immersive.

When connected to a smartphone or digital audio player that supports LDAC, it supports transmission of high-resolution sound sources up to 96kHz / 24bit. While aptX HD is 48kHz / 24bit and up to 576kbps, LDAC that supports 96kHz / 24bit can be said to be a "true high resolution compatible" device.

When connected to an iPhone, it will be played back with AAC, but if you use Sony's high-quality sound technology "DSEE Extreme", you can enjoy a higher-grade sound. Is AirPods Pro Sufficient for iPhone? However, in the sense that you can enjoy high-quality music with your favorite sound, the WF-1000XM4 is overwhelmingly superior.

Of course, the WF-1000XM4 is not superior in all cases, AirPods Pro is superior in ease of wearing and comfort when used for a long time, and AirPods Pro is superior in everyday use such as hearing condition when capturing external sound. There is also a face. Since I have both, I can use them properly depending on the time and the case, so there is no problem.

Especially in 2021, when the number of remote works increased, I mainly worked at home and had many online interviews (online presentations), so the noise canceling function that allows me to concentrate on the content with less sound leakage was very helpful.

The new material and multiple types of ear tips allow you to fine-tune the fit, so it fits in your ears. If you want to further improve the fitting, you can also use a commercially available custom ear tip. Next year, I'll try customizing.
