[Review] How has the Walkman A20 evolved? High -resolution+NC, H.ear on headphones with included earphones -AV Watch Watch

　One of the topics of '14 years in the previous A10 series that appeared as a model that could enjoy high -resolution playback at a low price, and I personally liked it.It is also introduced in the article of the year -end special project as a model of one push.The following three points have changed significantly as the A series has become the latest NW-A20/A20HN.

　Of course, the sound could not be heard even if the earphones were not high -resolution compatible, but even though the Walkman body can play high -resolution files, the attached earphone playback frequency bandwidth is the bandwidth that has been stipulated in high resolution so far.It was certainly incomplete that it did not cover.Even if the earphone that covers this is attached, the price has not risen significantly from the conventional A10 series (actual sale from 25,000 yen at the time of release).

　Immediately, I tried the noise canceling function with the combination of "NW-A25HN" and the attached earphones.The NC is ON/OFF, and the selection of [Full Auto Ainc], which is automatically set according to the environment, has not changed from A10.

　When I tried it in a room with an air conditioner or in the subway, I could see that a certain noise, such as the motor sound, was clearly reduced, but there was almost no pressure on the ears (eardrums) when turned on.The conventional model A10 and the included earphones used the NC function when traveling long distances, but there was a feeling that the eardrum was slightly pushed.With the further reduction, satisfaction has increased as a function you want to keep using forever.

　Regarding the sound quality, it is nice that A25HN did not change significantly when it was turned on NC."High -resolution compatible with NC" seems to be that the sound can be heard without much change even if it is ON.Even if you turn it on for a long time, you will not get tired, and if you wear it for a long time, you may forget that the NC is working.Even in such a case, if you turn off the Walkman, you can suddenly hear the noise around you, so there are actually quite noise in towns that are always quiet or homes where trains do not pass.I noticed.

　The low external noise means that you can listen to the silence of the song, so you can enjoy the difference from when the sound is coming out.Also, since you can listen to it without raising the volume too much, it has the advantage of protecting your ears from too loud sounds.

　The Walkman's noise canceling function has been realized from the previous model that it has high noise reduction performance, but it has not changed that it can only be used with attached earphones or some headphones made by Sony.If there is noise for a long time, such as an airplane, the NC function is actively used, so the author is two of the long -distance travel, the attached earphones of the Walkman, and the two to listen to high sound quality when not using NC.It was normal to bring earphones.

　This time, when I tried using A25HN NC for commuting and walking, it seemed that it was not only for the NC function, but it could be turned on on a regular basis.There is no significant difference in the battery duration during high -resolution playback, 30 hours in NC OFF, and 27 hours for ON.If the surrounding environment, such as traveling in the city or the city, changes the goodness of A25HN to make full use of [Full Auto Ainc].

　In addition, the A10 series also took place on October 13.1.With the update to 20, both high -resolution and NC functions can be used together.The Supported earphone "MDR-NW750N" (black/white), which is essential for the use of the same function, costs around 12,000 yen.NW-A25HN (16GB), which comes with earphones of the same color as the Walkman body, is around 28,000 yen, so if you buy only earphones, there is a slightly more expensive feeling.Whether the A10 user will buy a new one to A20, it is important to improve the function of the main unit.I want to check that point.
