Although I usually listen to a lot of songs, I also learn classical music, I think it is not a fungus, but I have always been strong and did not enter hifi, a metaphysical pit. It is a very realistic pursuit of noise reduction. The landlord has to sit every day. More than an hour's subway, the roar of the car is really annoying. To listen to music, you have to get the volume to the same loudness as the noise. Secondly, because there is no heating in Hong Kong, many air conditioners use The window machine, and then the place where the landlord lives is extraordinarily noisy, plus the empty road outside the window, the car passing at night will affect the quality of sleep. Therefore, the active noise-reduction headphones are long grass. Headphone noise reduction is generally considered to be divided into Bose and other headphones, so there is no other option to tangled in this selection. Although the new QC30 is about to go on the market, it is more worried about the battery life (the landlord belongs to The person who has long-term earphones), the second model of the new style affects portability and versatility, so it is still into the QC20.Bose store HK$23xx to start, licensed to send a year of maintenance, the price
Unpacking the crisp white carton, the envelope on the left is a policy file and the like...because it is usually used on Xperia, so it is the Samsung version.
A list of side accessories.
The main features on the back are introduced. However, there is nothing worth seeing...
Pull out the inner box, the same refreshing blue~
The upper earphone body has a thin black sponge cushion.
Lower accessories: a storage bag with (1) thick waste paper instructions (2) micro USB charging cable and (3) another pair of large earplugs.
Noise reduction unit. The same skin type coating as the old one, feels great, but the ash is also very powerful like other skin types.
When charging/turning on noise reduction, the LED light will flash, the charging will be yellow, and the noise reduction will be green.
The other side of the USB charging port.
Compared with the old gray-black spiral, the new style uses a blue-black color scheme, which makes it feel brighter and easier~
Fixed clip.
The remote control part is also one of the new upgrades. The front three keys are volume level and stop/play, respectively. The operation of the line control is relatively complete.
The blue button on the side is the switch of the aware mode. This function is mainly to filter the low frequency noise and turn on the middle frequency sound to prevent the vocal sound from being too slight. However, the landlord feels that after listening to it, it is more difficult to hear, and it is more harsh than completely turning off the noise reduction. ...
The other side of the microphone ~ and a two-dimensional code...
The earplug part. Although it is a large plastic, the texture looks good. The silicone sleeve is not compatible with other headphones, and the touch is very soft.
Tian Chao assembly.
Metal mesh.
Using the feeling of noise reduction, I believe that most people who buy this product are only for the noise reduction function... When the mall is listening, it is really "one ear" and it is shocked. Specifically, almost all the low frequency roar, package Including cars, subways, air conditioners, even subwoofers, etc. can be reduced to a level of comfort that allows one to concentrate on other things, such as reading, sleeping, working... whether in the car or in the room. Entering a space that is isolated from the world, its feelings can only be described as magical. Especially after removing a headset or temporarily turning off noise reduction, it is suddenly realized that we are accepting such a huge time all the time. Low-frequency noise effects. If you are like a landlord who likes to be quiet, you may not be able to use it. The high-frequency sounds such as alarms and horns will be reduced to some extent, but they can still be heard clearly. So there is no need to worry about sitting in the car and so on. It is very pleasant to play music at this time, it is almost the feeling of the movie BGM... the voice is between the two, need Listening more carefully can be distinguished, and it is easy to be confused with music. If it is necessary to hear vocals, it is best to turn on aware mode or not to play music. In general, it should be the best noise reduction experience at present. I don't know this. Whether the music sound is still the same loudness when the noise is turned on or off, but the volume that needs to be opened to 6~7 is now basically half or lower, and the sound can be satisfactorily achieved. The protection is self-evident.
Security issues Some friends say that if they wear Bose out of the street, they don’t even know how to hang when they are hit by a car... This is the truth! If you are using it on the street, be sure to reduce the music to the lowest acceptable volume. Although the tires and the road surface The friction and the sound of the airflow will not be completely filtered, but if you open a loud music at this time, you can't tell which car is approaching. Plus the domestic car and electric car are driving very unruly, out of the street. Always pay attention to safety.
The fit of the earplugs is very good, and it is not easy to fall out when sleeping. After the noise reduction function is turned on, there is a feeling that the ear pressure rises, that is, the feeling of "being stuffed in the box" that someone responds. About this point Personal acceptance is different, the landlord personally sleeps for a few nights with noise reduction, and does not feel obvious discomfort. It is best to go to the mall before buying, and then decide whether you can buy.
Sound quality because the landlord did not burn hifi, usually listen to songs and only use mobile phones to listen to 320k, so the evaluation of sound quality may not be very accurate, the hands can be compared to the earphones only Apple original, Sony original, all kinds of original, there is a XBA H1 (yes, that's the entry one). This headset doesn't give any surprises in terms of sound quality. It should be said that the performance of the songs (various ACG, JPOP, light music, classical) should not be as good as the entry ring. XBA H1, not to mention other earplugs at the same price: the bass is a bit too prominent, the vocals are more boring, and the equalizer needs to be manually adjusted. The sound field and the layering performance are also very flat. The stethoscope effect is not improved compared with the old model. However, compared with the difference between [0] and [1] of noise reduction, I am acceptable for the ordinary performance of sound quality.
Endurance use etc. Official 16-hour battery life, the actual use is basically reliable. The use of USB charging is a matter of opinion, although it can not be replaced like a dry battery, immediately replaced with a real blood resurrection, but can share a charge with the mobile phone, etc. The head does not cause a lot of trouble. After all, many people keep their urine bags at hand, so don't worry about no electricity available. Charging and noise reduction can be carried out at the same time. The noise reduction unit is indeed on the phone. The QC30 is more cumbersome, and it is inconvenient to play with the mobile phone. Then the wire is still a rhythm that looks very easy to rot, I don’t know if it can be changed during the warranty period...
Summary Compared to the metaphysics of other audio equipment, the QC20 headset is actually very simple: the best active noise reduction performance in in-ear headphones, buy or not buy is ultimately for this reason. Moderate work and design The sound of thousands of yuan, on this basis, is not cheap. However, if the life is like the landlord, there is a lot of noise in the life, but prefer a quiet environment, hope to listen to the song while reducing the pressure on the ear, active noise reduction Headphones should be the only choice that is almost needed~
Updating the Android version for use on the iPhone does not control volume and pause...
