Since entering the headphone pit, the basic one is for a year. The first headset was a BOSE SoundTrue earphone bought for 15 years. At the time, the requirement for headphones was just good-looking. After one year of use, it was really annoying to find a dragged-line headset. In 16 years, Bose SoundLink earphones were introduced. For a while, wireless is really convenient, but it's too big. Occasionally short-distance travel with too much space, and ear headphones used in summer so cool At the time, he wrote a sun list for the headset, and then turned it to give it the QC 30, which was then newly listed. I placed an order at the end of March. At that time, the QC30 was just basically listed. But I was lucky that when I filled with Jingdong plus members, the lottery attracted 999-500 coupons. Then I used Zhang Aunt’s 1000 gold coins against a 100 yuan Jingdong gift card, and finally paid 1898 to start. The BNM has yet to find a lower price than my starting price. It's simply pleasing, hahaha~ Let me talk about why I chose BOSE QC30: I need noise reduction. I need to be portable. I need wireless. I don't want to buy a headset anymore, because wearing a headset when I'm dozing off can't make my way to the dog's egg. And wearing headphones depends on the season, summer heat on the ear, winter hanging around the neck, this is my deepest feeling after using two headsets. At the time, only one earphone was required to perfectly meet my four requirements. That was the QC30 that was released soon. Although many people spit it like a dog's ring, but I buy a headset to buy it is its function, Yan value is not important here. ▲ spent half a year, the box has long been unaware of where to lose, directly to the daily state. In fact, the headphone bag is still pretty big, because the QC30's dog can not be bent and stored, so the bag can only be larger than the headset. ▲ Invisible zipper, texture is still relatively good. And although the QC30 is large, it is still very thin in the side view, so the portability is better than a thick headphone. ▲There is still a small storage bag inside the earphone for charging cable ▲ Whole body black dog collar printed with a small BOSE LOGO, but the publicity, everything is just fine. ▲ The headphone switch is hidden inside the dog ring, probably to prevent accidental contact. This button is particularly difficult to press! ! ! Every time you switch, you have to use your strength. ▲ The charging port is on the side of the dog's collar. After repeated opening and closing for a period of time, the plastic plug has been creased. It is feared that it will be broken off in a year. ▲ The volume adjustment, noise reduction adjustment, microphone are all in this small piece. The touch of the button is not good, press to feel soft and not crisp enough. ▲ The iconic BOSE shark fins not only improve the stability of the headphones, but also isolate some external noise. Even if you don't turn on your headphones to reduce noise, you can reduce noise. ▲ To be honest, when I first arrived, I was shocked by QC30's work. Really, compared to the two used before, it was considered to be relatively rough. The seams on the headphone shell were obvious. ▲Dog collars are designed with thick ends at both ends. Look at the finest part and always worry about accidentally cutting it off. ▲ There are clearly visible glitches on the edge of the dog's ring. This work is not just a fake product. I really doubt whether I bought a copy. ▲ To link to the QC30, download an App first, which is more trouble than before. The app can control noise reduction, volume, cut songs, switch headset link devices, and display the remaining battery power. ▲ dog ring wear effect, I think OK, there is no headphone hanging on the neck exaggerated. to sum up: When the BOSE QC30 first came out, most of the online searches were buzzing, mainly because the Tucao dog collar was too ugly. However, if you want to wirelessly reduce noise and continue your life, you have to plug in those parts. And in the second half of the year, Sony also released a similar dog ring wireless noise reduction headset WI-1000X, which proves that in the current technical conditions, wireless noise reduction is desirable and the collar type headset is the best solution. I have not tried other types of noise canceling headphones, QC30 is the first pair. To tell the truth, it did not satisfy my expectations. The filtering effect on vocals was more general, and the loudest people who could speak loudly could also hear more clearly. And it's open to music and not music. It's just two worlds. When you just turn on the screen, you don't sing the song. The maximum outside sound is just smaller and not completely disappear, but when the music is turned on, it feels the world is quiet immediately. Nobody talks.) It is not suitable for sports wear, it is not suitable for sound insulation during sleep, and it is not suitable for people to use. But it was just a good size, just a good noise reduction, just a good life, just to give me a just a good journey.
