1. Foreword: Immersive spatial audio technology debuts Bose QC noise-cancelling earbuds Ultra won the first launch.
The brand of BOSE, I believe everyone is no stranger, from headphones, speakers, to car audio, home theater systems, and even in the field of aerospace science and technology, you can see the figure of BOSE.
As one of the largest audio technology product R&D manufacturers in the United States, Bose's contribution to the field of wireless headphones is also obvious to all, and the world's first noise-canceling headphones are from the hands of the Bose brand.
This year, for the first time, Bose has introduced immersive spatial audio technology into wireless noise-cancelling headphones, with industry-leading noise-canceling technology, allowing users to enjoy a unique experience, and the first noise-canceling headphones with immersive audio technology are Bose QuietComfort Earbuds Ultra (hereinafter referred to as Bose QC Earbuds Ultra) just released by Bose.
1. Breakthrough Bose immersive audio.
The Bose QC Noise Cancelling Earbuds Ultra bring breakthrough Bose immersive audio, dynamic and static modes, and we're in a virtual space as if you're in a hall.
In dynamic audio, the sound follows you and stays straight ahead at all times, while in static mode, similar to head tracking, the sound changes as your head turns, making it accessible to you.
2. World-class noise cancellation technology.
The Bose QC Earbuds Ultra have world-class noise cancellation technology, and the intelligent in-ear sound field tuning technology will automatically optimize the in-ear sound field according to the structure of the ear canal, giving us the best noise reduction effect.
3. Refreshing design.
The QC Noise Cancelling Earbuds Ultra uses a new metal treatment process to present a smooth and shiny visual effect, and the earbuds look more refined and premium.
Moreover, these details not only add to the artistic sense of the earbuds, but also effectively prevent the adhesion of fingerprints and stains, so that the earphones always maintain a fresh appearance.
2. Appearance: Morning mist white color matching shows the business style The interlocking effect of the improved fixing ring cannot be shaken off when worn.
The battery compartment of the Bose QC Noise Cancelling Earbuds Ultra is in a morning mist white colorway, with a slight gray in the white, which looks very business-like.
In the ** position of the battery compartment, the brand logo of Bose is printed, and an LED indicator is equipped above.
On the back of the battery compartment, there is a Bluetooth pairing button.
The bottom of the battery compartment adopts a Type-C charging interface.
The earbuds are bean-shaped, with a flying fin structure and improved interlocking fit effect of the outer fixing ring, which makes it easier for us to wear it in the correct and reasonable position when using, fits more closely with the ear, and wears it more steadily, and even can achieve the effect of not being thrown off.
The Bose QC Noise Cancelling Earbuds Ultra have a built-in wearing sensor and a pickup microphone cut-out.
There are three metal charging contacts on the bottom.
The weight of a single earbud is only 6Around 2g.
In addition to the earbuds and battery compartment, three pairs of large, medium and small earbuds (S, M, L) and three pairs of fixing rings (No. 1, No. 2, No. 3), Type-C cable and product instruction manual are included.
3. Noise reduction measurement: Isolate most of the external noise and wear it, the whole world is yours.
Bose QC Noise Cancelling Earbuds Ultra feature world-renowned noise cancelling technology, with 4 microphones in each earbud that minimizes wind noise with dynamic microphone mixing and adaptive filters.
So what exactly is its noise-canceling ability?We selected three of the most practical scenarios for trial testing.
First of all, in a quieter office environment, we used a decibel meter to test the ambient noise of about 467db, at this time, the room is basically filled with the sound of colleagues tapping on the keyboard.
At this time, wearing headphones and turning on the noise reduction mode, the sound of the author's colleagues tapping the mechanical keyboard is almost completely isolated, only the sound of the author's own tapping on the keyboard is still looming, such as the operation of the chassis, the noise of air conditioning and blowing, and other common low-frequency noise, which can have an excellent elimination effect, bringing a quiet office environment at the same time, there is no obvious ear pressure feeling.
Then, we changed the test environment and went to the window to test the **, at this time, the turbulent car downstairs will produce relatively large noise, and the noise recorded by the decibel meter is 645db, wearing headphones in noise cancellation mode, only a faint honking sound can be heard, and the sound of the car rubbing against the ground has been completely isolated.
Then the author came to the side of the highway where the traffic was rushing, and the noise had reached 763dB, without headphones, it is already very noisy, after wearing Bose QC noise cancelling earbuds Ultra, nearly 60-70% of the outside noise is isolated, and only the low-frequency sound of the car slightly rubbing the floor can be heard.
In the process of the author's test, there was also a small episode, when testing the ambient noise, because I was busy shooting pictures, next to two cars on the side of the road, there was an electric bicycle behind that needed to be interspersed with the road, and the owner honked, but because the Bose QC noise cancelling earbuds worn by the author Ultra have been turned on the noise cancellation mode, I was even completely indifferent to the electric bicycle behind me, until the owner shouted, the author did not notice that there was someone behind him.
After this incident, it also indirectly proves that the noise cancellation ability of Bose QC noise cancelling earbuds Ultra is really strong, when someone is talking to you next to you, you have to take off the headphones and ask the other party: Excuse me, what did you just say?
Fourth, sound quality: the bass is sonorous and powerful, and the dynamic and static spatial audio brings you the most immersive listening enjoyment.
Immersive Spatial Audio technology is the biggest highlight of the Bose QC Noise Cancelling Earbuds Ultra, Bose Immersive Spatial Audio Technology breaks the inherent listening boundaries, this technology can make audio sound wider and deeper, no matter what kind of audio equipment or platform you use, it can make audio content present more layers and dimensions.
In fact, Bose's immersive spatial audio technology can be understood as adding the ability of deep noise reduction to the spatial audio, and also bringing two listening modes: "static" and "dynamic".
So how does it perform in terms of sound quality?In our actual tests, we auditioned several songs in different styles, such as "The Sixth Sense", "One I Love" and "Ferry".
When enjoying rhythmic ** like "The Sixth Sense", the Bose QC Noise Cancelling Earbuds Ultra can vividly show the strong impact of the drum beat and the richness of the percussion, bringing you an immersive feeling.
When enjoying "One I Love" and "The Ferry"**, whether it is the sound of high-frequency violin, piano and other musical instruments, or the mid-frequency vocals, you can accurately restore their details.
For the high-frequency section, the headphones deliver a clear and clear view of the articulation of instruments, especially the violin and piano, with impressive clarity and precision.
The treble of these instruments does not bring a sense of harshness, but rather gives a feeling of retraction due to their strong penetrating power.
In terms of vocal performance, it is pure and bright, there is a sense of volley, it sounds very comfortable, and the left and right channels are full of space, which also makes the three-dimensional sense of ** very significant.
In addition, the Bose QC Earbuds Ultra also have intelligent in-ear sound field tuning technology, which can optimize the in-ear sound field in real time according to different ear canal structures, adjust the sound and active noise cancellation technology, and bring users a customized sound experience.
Next, we experienced the immersive spatial audio technology of the Bose QC Earbuds Ultra.
In the app, Bose Immersive Spatial Audio brings two listening modes: "Static" or "Dynamic" mode.
In static mode, the sound is static relative to the space, and when we stay in place, such as sitting still, when turning the head, the sound changes the direction of propagation with the rotation of the head.
It supports 360° head horizontal following, when we are in more exciting scenes such as ** racing chase, as if in a movie, different sounds will whizz from different directions, feel the direction, angle, distance of various sound sources, and the sound is more full and three-dimensional, as if the sound surrounds you.
In dynamic mode, the sound is static compared to the wearer, the sound will be emitted from the front of the wearer, and move with the movement of the wearer, as if no matter where you go, there will always be a rich and wandering hall in front of you, just like **wrapping your ears and moving with you, just for you to interpret a vivid and shocking **.
In both modes, the sound quality of the headphones does not change much, and we can choose the mode of immersive spatial audio according to our preference.
5. Summary: 2,000 files of top-level noise reduction + dynamic and static two-state spatial audio.
Sound has its own power, and it has always been Bose's brand proposition.
Bose QC Noise Cancelling Earbuds Ultra, on the basis of inheriting the excellent noise cancellation ability of the previous generation, introduces a new immersive spatial audio technology, in the form of dynamic and static audio input, to meet the needs of headphone enthusiasts in the pursuit of on-site immersion and real restoration, and is also suitable for public enthusiasts.
In our tests, the static audio with a fixed sound source greatly improved the sense of immersion of the sound, and the sound seemed to change from the original binaural to a small closed space, which made people immerse themselves.
The dynamic audio that changes with the movement, the sound positioning effect is very good, it can simulate a feeling as if the hall is following the wearer, no matter how you go, how to turn your head, you can hear the vocal music as if from the front, this sound effect enhances the sense of immersion and space, so that the listener can feel more real, vivid**.
In terms of noise cancellation ability, Bose QC Noise Cancelling Earbuds Ultra provide excellent noise cancellation in various environments, such as on noisy city streets, or traveling on an airplane, it can isolate nearly 70% of external noise, and most importantly, no matter in any scene, you can hardly feel any pressure on the earbuds, which is another major advantage of Bose QC Noise Cancelling Earbuds Ultra.
It's no exaggeration to say that the noise cancelling capabilities of the Bose QC Noise Cancelling Earbuds Ultra have reached the ceiling level among TWS headphones.
Finally, Bose QC noise cancelling earbuds Ultra in the premise of ensuring immersive spatial audio function and world-class noise cancellation ability, in terms of sound quality expression, the middle frequency and low frequency will be more prominent, the treble part, the piano sound and vocals are clearly distinguishable, in terms of sound quality, Bose QC noise cancelling earbuds Ultra in the 2000 yuan price segment belongs to the upstream level, almost to an impeccable degree.
Overall, the Bose QC Noise Cancelling Earbuds Ultra are a noise-canceling earbud with excellent noise-canceling effect. The flagship TWS noise cancelling headphones with outstanding sound stereo sense can instantly give you a quiet environment when wearing it in scenes with extremely noisy sound, and the new immersive spatial audio technology is no longer limited to the immersive feeling of head tracking, dynamic audio, which can make the positioning of sound more accurate and realistic, and the output forms of these two audio formats break through the limitations of traditional spatial audio technology.
If you're looking for the ultimate in noise-cancelling performance when shopping for headphones, then the Bose QuietComfort's noise-cancelling earbuds Ultra, which has the industry's top noise-cancelling capabilities, are a perfect fit for you.
