This is what really happened.
On a flight from Beijing to Shanghai, I saw a group of family tours with grandparents, uncles, aunts, moms and dads, brothers and sisters. So many people are in the same family, and they are on the brain. Narrow plane, you can imagine how lively the scene is. So all kinds of "there are no blankets", "hey, sit down", "where is the toilet?", accompanied by the cry of the child's no reason, passed in Unfortunately sitting in my ear behind them.
Plus, they have all sorts of unreasonable demands such as "Why can't go to the toilet when the plane takes off", "Why can't adjust the seat when the plane takes off", "Why can't the empty seat sit?", the flight attendants can only squeeze the smirk and their Explain, and I am behind the head that didn't wake up in the morning, restraining the urge to worry at any time. Until the grandfather in front of the family finally clashes with the passengers in front of him, just because this grandfather wants to put his feet in the front row. When I was on the seat cushion, I couldn't stand it anymore. So I struggled to open my bulging backpack and smashed out the smashing equipment in a full set of tools - a pair of Bose QuietComfort 35 wireless noise canceling headphones , hereinafter referred to as QC35.
Ok, I admit that the description of the last sentence is somewhat exaggerated. But at that time, there is really no more reassuring equipment than a noise-cancelling earphone. After all, high-quality people like me are not with those who are not qualified. People are so jealous. So I can't afford it, I can't afford it. Put on the Bose QC35, turn on the noise reduction button, and let the whole world clean.
Stop!
Any noise-cancelling headphones can't be really clean, even the noise-reducing technology Bose can't do it. This is a fact. Here is the principle of active noise reduction, which relies on the microphone on the headphones to collect the surrounding. The ambient noise is then transmitted through the digital processing inside the earphone to emit the reverse sound wave to offset the external noise. Therefore, the effect of active noise reduction depends on the microphone configuration and the manufacturer's own digital processing algorithm. But the noise is complicated and varied. In fact, it is impossible to have a perfect algorithm that can completely offset them.
Therefore, manufacturers' research on noise reduction technology mainly focuses on eliminating some irregular noise (mainly in the middle and high frequency noise) and improving the comfort of ears under noise reduction. Bose is a manufacturer in this field. They are doing very well, and they belong to other manufacturers' expectations. Bose, who doesn't know their noise-cancelling headphones is good.
Back to the Bose QC35, when the bear children and the old ones were unscrupulously "opening tea" in the cabin of the aircraft, I turned on the noise reduction switch of the Bose QC35. The Bose QC35 is the first collection of their noise reduction and Bluetooth. Functional headphones, so when you don't listen to music, just want to make the world quiet, just wear it directly to the head, no need to worry about the headphone cable. But Bose will set the noise reduction and Bluetooth switch together, so Turning on the noise reduction will also enable Bluetooth. At this time, the Bluetooth connection will be sent out in the headset, such as looking for the device, successfully connecting, not finding the device, etc. If the connection is not made, the headset will automatically turn off after a few seconds. Bluetooth, you can't hear the prompt, then it is really quiet.
The noise reduction effect of the Bose QC35 is better than that of the previous generation noise canceling headphones QC25. It is obvious that the ear comfort is improved. Since the principle of active noise reduction is to reflect the reverse sound wave, the reverse sound wave is offsetting the external noise. At the same time, it will also cause some pressure on the ear. This feeling is like the swelling of the tympanic membrane in the lower ear when climbing, and this is not very obvious when using Bose QC35, only There is a slight sense of swelling, which is probably the reaction from the first floor to the elevator to the 20th floor. This is different from person to person. Anyway, for me, wearing a sleepy thing will not affect .
Noise-cancelling headphones generally have a strong ability to eliminate continuous and regular low-frequency noise. The Bose QC35 is also wearing it. It really can't hear the engine sound of the aircraft. In addition, the noise of the headphones itself is very weak, so you can do it. To make people feel at ease. The real test of noise canceling headphones is the elimination of medium and high frequency noise, such as human conversation. At this point, Bose QC35 also has a good performance, the radiation range of the entire vocal is reduced to a point. But it can't be completely eliminated. The effect is similar to directly plugging the ear with your fingers, but it can't achieve 100% soundproofing. Turning those annoying conversations into cats is enough to make people feel comfortable.
However, the Bose QC35 seems to have no way for some sharp high-frequency noise. On the plane, I am wearing a QC35 to doze off. As a result, an old man not far away is playing on the tin foil on the box lunch. The sound is still in my ear, and it is very clear. At this time I can only look at the sky outside and sigh, there is no other way. But this situation is only a few, even the noise reduction headphones of other countries have the same result.
Another point that I admire is the sound quality of the Bose QC35. Maybe you will say that the noise canceling headphones talk about what sound quality. You are wrong, the sound quality is also important for noise canceling headphones, but it does not mean the sound quality under normal playback. Since the noise canceling headphone will perform digital processing again after turning on the noise reduction, it will inevitably introduce some distortion. Especially after the reverse sound wave is transmitted, it will definitely affect the normal sound information, so the noise canceling headphones are generally open. The problem of degraded sound quality after noise reduction.
But this problem does not exist on the Bose QC35. It does not notice any deterioration in sound quality after noise reduction. In my opinion, it has improved. Not to mention the sound quality under Bluetooth connection, turn off and on under the wired connection. After the noise reduction, I think I still prefer to turn on the noise after noise reduction. The main reason is that the sound under the noise reduction is somewhat slack and soft. When the noise reduction is turned on, the sound is immediately tightened, and the sound field is more Big. Although the vocals are a little sharp, not so mellow, but still acceptable, it should be said that it is another style. Bluetooth + noise reduction under the sound quality and cable + noise reduction sound quality is excellent, so it is strongly recommended to use Bluetooth, Although this seems to be a normal thing. Bose QC35's voice is still very focused on the low frequency, but still can ensure the clarity and clean sound, strong and low distortion style is not disappointing.
In order to be portable, the Bose QC35 is still a foldable design. It also comes with a storage box and a special socket for the aircraft. This generation of products has been added to the Bluetooth module, so in order to reduce the weight of the headphones, the material is not plastic, but Glass fiber filled nylon. From the appearance, I can't see the difference between plastic and plastic, but the texture is really good, it is very solid. The earphones are not heavy, just 310g. the sponge of the head beam and The ear pad of the earmuffs is also very comfortable to wear, and it won't feel tired for a long time.
Bose QC35 is also very good in terms of battery life. At the same time, noise reduction and Bluetooth can be turned on. It can be used continuously for about 20 hours. If only noise reduction is enabled and wired connection is used, it can play for 40 hours. I used 2 and 3 consecutively. Hours, still suggesting that the power is 100%, it is quite durable. This time the QC35 no longer uses the AA battery, but the built-in battery, using the microUSB interface to charge.
In short, fortunately, with a Bose QC35, this "hot" journey did not make me live. The engine sound of the aircraft does not make me feel annoyed, but the bear child and the old-fashioned cry I can't stand it. I used to be able to squat on my own. After wearing Bose QC35, I can at least make myself comfortable. I only ask for six cleanliness. I don’t want him. The price of 2888 is expensive. Bose has always been such a pricing style. I have long been used to it. Even though the Bose QC35 is equipped with the NFC function, it is necessary to turn on the noise reduction switch before it can be connected to the NFC device. This is not very understandable.
In general, the connection between NFC-enabled audio devices does not require the receiver to turn on the power. Just use the phone or player to aim at the NFC logo, and the Bluetooth speaker or headset can automatically turn on the power to connect. But Bose QC35 The power must be turned on first, and the NFC touch is effective. Or is Bose improving on the next generation?

Until the grandfather in front of the family finally clashes with the passengers in front of him, just because this grandfather wants to put his feet in the front row.
