Bose active noise canceling headphones

Very early, the QuietComfort series headphones have become the endorsement brand of noise-canceling headphones, and the noise canceling headphones is a small category in the earphone category, but a small consumer of headphones. The birth of the QuietComfort 20i will make consumers feel that active noise reduction is so wonderful.

The author's experience of using the noise canceling headphones on the plane for 180 hours per year really suggests that you need to buy a pair of noise-canceling headphones. If you have friends who often fly with the noise canceling headphones in the air, he will definitely With you a glimpse of the magical experience of using noise-canceling headphones in the cabin, noise canceling headphones is an addictive product, not only because of its cutting-edge technology, but also in an environment that is annoying and noisy. You bring a completely peaceful listening environment.

Bose introduced a head-mounted noise canceling headphone QuietComfort 25 (hereafter referred to as QC25). As an upgraded version of the Bose classic noise canceling headphone QC15, QC25 has changed a lot in many aspects, and these changes are all around the application of the user environment. Sublimation in terms of wearing comfort and portability. As a QC15 headset that replaces Bose's legend, what surprises will QC25 bring to us?

As the user of QC15 is most sensitive to the change of QC25, QC25 adopts the folding storage method to make the storage box a small circle. This design makes the carrying change more convenient, and the exclusive backup battery and aviation adapter storage position in the storage box. No need to worry about the battery life and nowhere to store the aviation adapter, the most important thing is that the QC25 has a major change that can still be heard under passive conditions, which makes the Bose QuietComfort series of noise canceling headphones fully equipped with passive playback function, let QC25 The scope of use has become more extensive.

The Bose QC25 ear cavity is made of fully anodized frosted aluminum for added weight and durability. Breaking the monotony of QC15 single color, QC25 brings users a new black and white main color palette. The all-white head beam and blue elastic band make the QC25 more relaxed and trendy. The top of the head beam is wrapped with Alcantara material. High-tech materials are commonly used on the seat cushions of the traffic jam to provide comfortable pressure, and the interior of the head beam is made of more skin-friendly fur material, combined with leather earmuffs for excellent wearing and breathability.

Bose's multi-year patented noise cancellation technology combined with unique digital electronic chip technology provides amazing sound and noise cancellation performance and memorable sound. The TriPort acoustic structure is also applied to the QC25, so you can always feel Bose's "original sound". Re-emergence of the pursuit of persistence.

Bose QC25's two main functions involve Bose's patented technology: noise cancellation and sound effects. Here we have a detailed analysis of how to achieve excellent noise cancellation and exciting sound technology, which has created brilliant in QC15. The same as the new active noise cancellation new flagship QC25 can be blue, giving users more excellent listening experience.

Active noise cancellation technology is Bose's housekeeping technology. It detects the noise at the ear through the microphone outside the cavity, corrects the signal to achieve unwanted noise, and interferes with the background sound to achieve a quiet listening environment. The Aware Mode can switch between the noise canceling environment mode and the external information acquisition mode. The Aware Mode mode still has a noise canceling function. The difference is that the QC20 sends some information to the ear when collecting the external environment sound. In this process, the background sound will still be faded. In Aware Mode, users can listen to music while receiving external and useful information.

QC25 active noise cancellation provides a quiet listening environment. Bose provides users with TriPort acoustic structure design. Through the physical characteristics of the small earphone cavity, the external airflow is pushed into the ear through the earphone, and the aeroacoustic principle is used to achieve fullness. Thick low-frequency effect. Due to the use of active noise cancellation technology, the electronic circuit can't avoid the “click” sound during the denoising process. Therefore, the circuit noise elimination technology is added to the QC25 to reduce the “click” sound of the electronic circuit. Users provide a quieter, clearer, purer listening environment.

Subjective listening sessions We mainly use smart devices such as iPhone, iPod Classic and iPod Mini, which are used by everyone, as listening devices. The tracks are more popular with popular, jazz and electronic music types.

Listening to the environment, except for a plane traveling back and forth, most of the time is in the subway and the street. Of course, in the street, the author turns off the active noise cancellation function. Without the noise cancellation technology, there is no electronic without playing music. The noise, the internal circuit noise-canceling module completely offsets the noise of the electronic circuit.

When the noise is turned on, most of the ambient noise is filtered out. The vocal of the external environment can be heard slightly. Due to the superior listening environment, the QC25 will make you fall in love with the noise canceling headphones. The unique listening environment, although the ears cannot capture the sound waves, but the Bose QC25 can still provide a wide sound field performance, the low frequency is full of American power and extremely moisturizing elasticity, as the basis of the music rhythm low frequency on the QC25 performance primary and secondary Clearly, the IF voice is a little away from the ear, the space is clear and full of positionality, the transition is clean and neat as smooth and natural, the high frequency is horizontally extended and has a high degree of extension, making the space of the music infinite open.

When the noise canceling mode is turned off, the sound field will become wider, the low frequency is much thinner than the open noise canceling mode, the power sense and elasticity remain, and the mid-frequency voice is farther away from the ear. The high-frequency extension does not change much and still has a good extension.

In the whole process of use, line control is very worth mentioning. Whether you are operating the equipment on the road or on the plane, you need to take out the equipment. After the remote control, you only need to perform a blind operation to play music and switch songs. Answer the phone.

If you still think that the active noise canceling headphones can only be used on the plane, then you really don't realize how serious the noise pollution in our lives is. Usually, you will choose to increase the volume to change the noise. Imperceptible damage to your ears and hearing, and the noise canceling headphones like the QC25 can correct the wrong listening application for you. Turning off the noise canceling function can make you pay more attention to the safety of the surrounding environment and turn on the noise cancellation. Just give you a quiet world.

Advanced noise cancellation technology, Triport acoustic structure, unique digital electronic chip technology, passive playback, easy and stylish color matching, and smaller storage bag all make Bose's new QuietComfort 25 active noise canceling headphones, which is also Bose new The essence of music concept.
