We talked about in GIGAZINE before, scheduled to be released on April 21Sony's noise canceling headphone "MDR-NC500D" which can cut the surrounding noise by about 99% for the first time in the worldBecause I was able to borrow, I will deliver the experience report at once.

In addition to carrying the "AI noise canceling function" that automatically selects the optimal noise canceling mode by automatically determining ambient noise by digital processing, it also features a "digital equalizer" that realizes realistic high-quality sound reproduction "Although it is a high-performance headphone that realizes high-quality sound reproduction, the use feeling was quite a thing including the wearing feeling.

Details are as below.
The back of the box looks like this.


Instruction manual etc. are included when opening.

Viewed from the side.


Ear pad. The cushioning property is very high, the burden on the ear is small, so it will not get tired even if you are wearing it for a long time. Also, since I firmly hold my ears, I did not fall even if I ran with it.


The right unit has a monitor button, power switch, "AI NC MODE" button which realizes noise canceling of about 99%.

Although I used impression, the first impression was that it was very light and comfortable to wear. Easy to adjust the width of the band, the cushioning property of the ear pad is high, so it fits to various head sizes.

Moreover, it has built-in rechargeable battery,Like a conventional modelEven if you do not pass the connection cord with the battery case in between, you can use the noise canceling function just by connecting the cord directly from the player like ordinary headphones, so it is very convenient to use.

Although it is a noise cancellation function which is worrisome, although question marks remain as to whether or not ambient noise can be cut by 99%, it seems that noise is cut off compared with the conventional one, together with the ear pad fitting to the ear It was.

Is it the effect of the "AI noise canceling function" that automatically selects the optimal noise canceling mode by digitally processing the surrounding noise, the sound of the desktop machine's fan is reduced in the office, and the train I felt that the door closing sound and the announcement in the car were reduced. However, when you use it in a train, you often lose the announcement in the car, so you need to be careful about getting through.

Although it is about sound quality, it sounds like covering the entire ears, unlike Canal type and ordinary earphone etc. for Sony-like low-pitched sound quality clearly, spreading sound is born and hearing becomes hard to get tired I will. It seems to be able to use for a long time in this case.
