As a member of the senior Wannian Dive party, he finally decided to write an original support for the aunt to change gold coins. He thought that the language was not good, especially the headache composition. At that time, the college entrance exam scored double digits in Chinese at the time. After one of the 985s, it was successfully abused by the students for several years to doubt their lives. We asked people to forgive and correct me in bad places.
In fact, this headset was started during the 618 period of 16 years. It has been half a year now. In the second half of 16 years ago, BOSE's QC25 and QC20 had been pushing various kinds of noise-reducing headphones. At the beginning, I was resistant, and then it was normal to buy a story. I watched the original and the bottom of the story. Comments, the hearts of dark waves, and then encountered 618 milk tea, the country's own line of historical low prices, could not bear to start a thigh decision, the price of 1799 spent 80 full coupons, and finally 1719, in fact, that bought bose products Jingdong gave a Bluetooth headset coupon (value of friends comments area), I bought a Bluetooth headset and turned back 240 tablets. After getting the hand is the normal rhythm of buying gray, not to mention the summer is so hot and can not wear, until the weather turned cool and good use for some time, so now can share with you experience.

1. Usage: QC25 is powered by No. 7 battery, the battery compartment is on the right earmuffs, the basic zero learning cost is obtained, there are instructions for use on the packaging, and 4 small diagrams are concise, this praise! A battery can be used for 35 hours. The battery compartment in the box can also be used as a backup. If the battery is depleted, it can still be used. It is just "when there is no electricity, the noise cancellation and active equalization that provide more realistic audio reproduction in electronic way Device technology is disabled. These technologies need power to work." This is an excerpt from the official website, we look at the map.
2, wearing feelings: For the choice of headphones, I personally always ranked first in comfort, wearing uncomfortable listening to the crime. Earlier bought beats solo HD, sound quality brand name aside and talk about it, at least later do not buy pressure ear type headphones, and in early 17th Apple's official website orders iphone wireless solo are too lazy to study directly off, If it is studio, even if I have a wired payment, I will be interested in it. Let's talk about the QC25 wearing feeling, really comfortable to float, the most comfortable wearing a headset, the right temperature can almost always wear, mentioning Dafa 1a wearing giant cool, It's only relatively hotter. Before listening to people that used BOSE headphones products that kind of comfortable feeling can not go back, I really experienced it.

3, noise reduction experience: noise reduction did not have to say, QC35 and 1000x came out before the earliest noise-canceling headphones the strongest, in fact, they have not experienced it is difficult to describe this thing. To tell a practical scenario, there is a street near the place of residence, about four dozen meters away from the opening of some of the domestic mobile phone factory stores, equipped with subwoofer in front of the store every day playing against the bang singing competition, the magic is the occasional There are also clerk who shouted wheat, and friends who live in the suburbs or in towns and towns should feel very touched. So, if you want to calm down and do something that requires a little attention, this noise-canceling headset will do a good job, but my usage is not to simply insert a noise reduction line, the effect is indeed significant, conservative 90% of the noise can be eliminated If you drop it, the remaining part of it can't be lost and it's far from you.
4, sound quality experience: I am a fungus, those professional sense of hearing also said not too, but there is a very clear experience, noise reduction before and after opening the sound quality will be very different, open the noise reduction becomes more bright, More clearly, I don't know if this is the so-called “Bose® Active EQ active equalizer technology†that is written on the official website.
to sum upadvantage
1, affirmative noise reduction is a biggest advantage, not used 35 but said that the noise reduction function QC25 and QC35 basically the same level, often go out and like to listen to songs, in order to protect the hearing into a value.
2, wearing a first-class comfort, this can be emphasized once again.
Shortcomings
1. The proportion of plastic accounts for more, it looks a bit fragile, and it is not enough to show off.
2, and no noise reduction is particularly extreme, such as those clerk called shouting treble can still be heard, in the plane is, even if the engine's low frequency sound is still a little smaller, after all, head-mounted, physical noise than not Upper earbud noise cancelling headphones.
3, no Bluetooth, this requires a specific look at the budget and the actual necessity, forced to be considered a disadvantage.
