Bose QuietComfort 25 noise canceling headphones

I remember that when I was young, I experienced the noise canceling headphones for the first time in the Bose store on the Shanghai Harbour Building. I was surprised that there were so amazing headphones in the world that I could isolate all the noise, as if the whole world only left me alone. In the past, the noise cancellation performance of Bose headphones is still so difficult to surpass. Recently released Bose QuietComfort 25 (hereinafter referred to as "QC25") to replace the location of QuietComfort 15, this time, what new tricks will Bose come up with?

Bose has always had a very clear design style, that is tough, high cold. But at first glance, we know that QC25 obviously feels the pressure from Beats, the scornful white and simple design seems to swear by Bose. I started to change the small fresh route.

Whether it is QC25 or previous FreeStyle, SoundLink headphones, Bose is no longer pretending to be cold, but the shape of the headphones is fashionable to cater to the tastes of young people. Compared to the business style of QC15, the QC25 earmuffs are not redundant. The texture is very simple, and the silver-white metal covers the entire surface. Only the logo above and the appearance of the approximate QC15 are still mentioned, this is indeed the Bose's product.

Even the headphone cable is specially selected to match the white body. The QC25 is no longer equipped with two wireless control and cable headset cables like the QC15. Instead, it directly uses a wired headset cable. Of course, the headset cable remains. It is replaceable, and currently the line control only supports iOS devices.

The most basic requirement for earphones is that they are comfortable to wear. On the one hand, the headgear pads of the QC25 use special materials in high-end cars, which are wear-resistant and dirt-resistant and can prevent the headphones from slipping. On the other hand, the ear pads are made of memory foam, and Covered with a soft and delicate outer layer of leather, the earmuffs are breathable, they won't feel stuffy for a long time, and they can stay close to the sides of the head to prevent leakage. The left side cavity provides noise cancellation. The power button has an AAA battery compartment on the side, and a battery can use the noise canceling function for about 35 hours.

In fact, noise cancellation can be divided into passive noise cancellation and active noise cancellation. The so-called noise canceling headphones belong to the latter, that is, the reverse sound waves are emitted from the microphone outside the earphone to achieve the purpose of eliminating noise. We will be in QC25. A number of fine holes are found on the earmuffs. These microphones are the key to active noise cancellation. When the headphones collect external noise, they will cancel out by the internal noise cancellation algorithm.

In general, any audio manufacturer will not advise users to turn on noise cancellation for a long time outdoors. This is because the headphones will unambiguously denoise all the recognized noise. The value of the noise canceling headphones is still the same. Bose QC25 is a noisy place for airplanes and trains, and the Bose QC25 is a "natural enemy of engine noise." Due to the characteristics of the noise canceling algorithm, it is very popular with some continuous and consistent specific frequency noise, like the rumbling and uninterrupted noise of the engine. It is most suitable for the appetite of the noise canceling headphones. When we put on the QC25 and ride on the plane, you can find that the noise of the disturbing aircraft is so vulnerable in front of the QC25, it is called "noise cancellation". "The absolute field is out of the way, so quiet noise reduction effect is really drunk.

Although QC25 can't eliminate 100% of the noise, but the "quiet" standard, its noise reduction effect is quite satisfactory. You will no longer be disturbed by the sound of airplanes, cars and train engines. If you want to do anything you want to do, the only thing you need to worry about is not to sit over because of too much comfort. But noise reduction is not omnipotent. Bose QC25 is mainly composed of low frequency sound. The noise is very effective, and the elimination of the voice of the conversation and the sound of the instrument is not so sensitive. It is also for security reasons and retains a certain external sound. However, the absolute field of QC25 will still force most conversations to In the distance, as far as possible from our range of hearing, this is the best effect that can be achieved by the noise canceling headphones on the market.

Of course, noise canceling headphones are not all advantages. Many similar products are often accompanied by noise, swell and poor sound quality. The reason why there is noise is because the noise canceling headphones generate unnecessary audio signals in the circuit processing. So many people will hear the buzz. At this point, the Bose QC25 uses a new digital chip technology to minimize the formation of noise, and there is no extra noise at all. As for active noise cancellation. The vacuum of the ears is swelled, but it will be some but not obvious. In general, QC25 will not be uncomfortable for some technical reasons.

Moreover, after the noise is turned on, the effect on the sound quality is very slight, the sound is transparent, and the layering is distinct. Although the medium and low frequency is more, the resolution can still be interpreted as a clean and bright sound. Turn off the noise cancellation and fully use the player. Direct push is an alternative solution after the headset battery is exhausted. At this time, the sound level is degraded due to the increase of the impedance of the earphone, and the resolution cannot be played out. Therefore, if the battery life is sufficient and the travel safety is ensured, we suggest to turn on the noise cancellation and listen to the music. it is good.

Remember, don't wear noise-cancelling headphones on the street. Although it doesn't make you completely unable to hear the outside world, the too quiet environment may make you ignore any speakers and other sounds. In fact, Bose should add a mute button. Instantly turn off noise cancellation and music playback, which is very helpful for traveling or listening to station reminders.

Such excellent noise cancellation performance is produced by Bose, naturally there will be a cheap price, QC25 that 2680 yuan price is really drunk. But on the noise reduction effect, in addition to Bose, there is no other two, I know that many airlines will standardize Bose headphones in first class for business people who travel long distances. Some students who are surrounded by noisy students and white-collar workers can't wait to have efficient noise canceling headphones to keep their ears quiet. And if we spend money to buy peace, do we do less?
