Sony Xperia Z2 is the world's first smart phone with built-in noise reduction. Of course, Sony has prepared relevant accessories to play its role. This noise reduction headset MDR-NC31EM, which is standard in some versions, was born for Xperia Z2. What about the actual experience?

The MDR-NC31EM is the standard headset for Xperia Z2 in some regions in some periods, such as the exclusive version in mainland China and Taiwan. Of course, most of them should be purchased separately. In terms of packaging design, it is the standard of Sony accessories this year. The interior is mainly purple, which sets off the color of Xperia Z2.

There are only three pairs of earplugs of different sizes and several useless manuals.

For most people, the appearance of the MDR-NC31EM is quite special. Compared with ordinary earphones, its dynamic circle reaches 13.5mm. Due to the noise reduction function, there are microphones and electronic circuits in the cavity. It should be noted that the MDR-NC31EM plug is 5pin, which is required by the noise reduction function. Of course, it can also be used normally when plugged into other mobile phones. It should be noted that the MDR-NC31EM supports microphone calls.

MDR-NC31EM was born for Xperia Z2. Of course, it is the actual test with Xperia Z2. At present, the MDR-NC31EM is available in black and white, which is relatively simple to match. Its wire material is more solid than that of ordinary earphones, and the long and short wire design performs better on the earphone effect.

The MDR-NC31EM with Xperia Z2 is actually quite simple to use. Relevant options will pop up after insertion, and you can use it after selecting noise reduction earphones. In terms of function, because there is no wire control, there is no switching function. MDR-NC31EM currently provides three noise reduction environments, namely, aircraft, bus and office.

Of course, the noise reduction effect of MDR-NC31EM should be actually worn. When MDR-NC31EM is used in the office and noise reduction is enabled, it can be clearly felt that the whole breath is quiet and the voice is completely eliminated. However, the sound when the mechanical keyboard touches the bottom cannot be avoided. Through a simple test, the MDR-NC31EM can not filter the high-frequency part of the sound very well, which is specifically reflected in keyboard strikes and other situations.

On the subway, the noise reduction effect is quite obvious. Before, I couldn't stand frequent sounds when I went to and from work. After using the MDR-NC31EM, except for the high-frequency sound at startup, it has completely quieted down. Even in the chaos of passengers, there is no pressure.

As one of the highlights of Sony Xperia Z2, its noise reduction needs to be matched with a special headset, but most retail versions do not match this headset, which really needs to be complained about. The MDR-NC31EM also performs very well in noise reduction. Although it is still weak in high-frequency sounds such as keyboard tapping, it is enough for most people to use in daily scenes. I personally recommend Sony Xperia Z2 users to start one.
