3D Movies have just been popularized by all mankind, VR Class products have quietly entered people's lives, and people's pursuit of visual perception is increasingly close to real experience. There is no end to people's pursuit of sensory experience that is not parallel to the real experience. Even the sound experience has begun to pursue 3D effect. Ordinary earphones and even HIFI If the sound quality of Grade A headphones is good enough, it will create an atmosphere of a grand sound field, but after all, the authenticity of this sound field is limited. And this experience COOLHEAR V1 3D&ANC Active noise reduction earphones are designed to 3D A headphone with sound field as selling point. Can cooperate VR Double vision and hearing 3D As a digital enthusiast, the effect experience is full of infinite longing for this experience. However, the active noise reduction function has only been heard before and has never been experienced. The so-called active noise reduction means that the earphone generates the reverse sound wave equal to the external noise through the noise reduction system to neutralize the noise to achieve the effect of noise reduction. This function can eliminate noise when listening to music in noisy environments such as planes, trains and cars. COLLHEAR V1 The two main selling points are very attractive. Let's have a look at the specific performance in use. Let's talk less and get straight to the point.

As a headset, COOLHEAR V1 The box of is really not small, the black theme color of the outer package is slightly elegant, consistent with HIFI Headphone positioning and taste. A transparent rigid plastic hook is arranged on the top of the package for convenient wall hanging and display. However, packaging is used to protect products. For the box controller, the ash is basically collected after unpacking. For users with thicker lines, it may be discarded directly. however COOLHEAR V1 I really hate to throw away this box.

The upper right corner of the front of the package is COOLHEAR V1 Of LOGO 。

The lower right corner of the front is marked with“ 3D Holographic sound field restoration "indicates the main feature of the product. The word "hologram" often appears in the "holographic projection" of some science fiction movies, without the display of screen media 3D The way of image appears in the expression of sound characteristics this time, 3D The sound field must sound very three-dimensional. I'm looking forward to it COOLHEAR V1 The performance of listening sense.

All the selling points and features of the headset are listed on the back of the packaging box: restoration 3D Holographic sound field 3D Space noise elimination, humanized breathable design, aviation aluminum shell, low power consumption and environmental protection design, the following are COOLHEAR "Audiovisual Field" patented technology registered trademark. At the bottom is a list of accessories. The specifications of the earphone will be introduced first. Introduce some main parameters:

ANC Noise elimination peak ＞ 25dB ；

ANC Noise elimination bandwidth: 20Hz — 1KHz ；

Frequency response range: 12Hz — 20KHz ；

Rated output power: 30mW;

Unit diameter: 40mm ；

Horn impedance: thirty-two Ω ;

Battery capacity: 600mAh.

The package is divided into two layers, the outer skin and the inner box, and the design of pull type.

Although both the inner and outer layers of packaging are paper boxes, the inner box has been sanded and pearlized, which improves the hand feel and gives a visual illusion that it is not paper material. The material of the inner box has improved the product quality. The design of the inner box is very simple, and there is only one on the front COOLHEAR Hot silver of LOGO 。

The back of the box conveys the product theme "Hear the future". It is also a hot silver character.

Use a knife to cut the transparent adhesive tape on the side to open the upper cover of the inner box and see the same black headset storage box.

The front and back sides of the headset storage box are the same as the packaging, and the front side LOGO The design of the back theme. It is also very simple.

Because the author COOLHEAR V1 The package and storage box of are very popular, so I can't help putting more pictures. Now let's see what the earphone looks like. Open the zipper of the storage box. The storage box is designed to open up and down. The zipper is designed in cyan. The main black color is matched with the cyan zipper, and the color matches the style. Open the storage box, you can see a pair of black ear bags lying flat. It is still a simple design, and every face is branded LOGO The shell is made of aviation aluminum.

Turn the earphone upside down, and the two ear bags are printed with L/R It should be a very important detail to distinguish the left and right ears. If you wear the left and right ears on this earphone, the positioning of the left and right ears will be opposite. So this L/R It's very big. It should be easy to distinguish. In the storage box, a smaller storage bag is also attached with velcro three point five One audio line USB Charging cable and active noise reduction headset need power support and charging. The charging time is three Full hour, endurance fifty-five Hours.

The audio interface is on the left side of the headset, and the pluggable design is convenient for storage and DIY wire rod. The design in the left ear is also in line with the habits of most people. There is no interface in the right ear, so listeners who are used to plugging in the right ear can only make do with it.

Micro USB The connector is designed on the right side of the headset, and the indicator light is beside the connector. If there is a rubber plug, it is good. If the interface is blocked when not charging, it can prevent dust.

The indicator light is on when charging, the red light is always on during charging, and it is off after charging.

The audio cable has the functions of remote control and microphone. The upper and lower buttons are volume increase and decrease buttons, and the middle button is call connection and music pause buttons. The material is plastic. The volume key is convex, and the play key is straight. You can distinguish the difference by blind operation.

The active noise reduction switch is set to the right, and set to ON When the green light is on, first put on the earphone and then turn on the switch, there will be an obvious feeling similar to the sudden failure of hearing, which proves that active noise reduction is on. This feeling is very obvious. One second ago, there was stethoscope effect and the rustle of the outside world when I put on headphones. Suddenly, the feeling noise disappeared as soon as the background was dark.

The connection between the head beam and the ear bag is made of metal. The metal shell and the metal connecting arm make the earphone very powerful. The metal surface has been sanded and oxidized, which is not easy to leave fingerprints. The corners have been smoothed, and there are no obvious hard corners.

It can be seen from the side that the metal connecting arm is turned from the upper part of the ear bag to the middle part of the ear bag, surrounding the ear bag four One in ten, this design should be considered for earmuff rotation.

The inner side of the head beam is soft anti slip rubber, which looks good in texture. The touch is not like ordinary rubber. It has the touch of skin like materials. The softness is moderate, the friction is great, and the anti slip performance is good when worn on the head. The reason for concluding that it is rubber material is that the author can smell the smell of rubber with his nose.

The metal connecting arms on both sides of the head beam can be expanded and contracted according to the size of the wearer's head. The sense of expansion and contraction is obvious, and it can probably be expanded and contracted 3cm Left and right length, shared twelve Paragraphs are adjustable.

The most important part of earphone wearing comfort is the outer skin of the ear bag. The outer ring is covered with leather. The skin texture is fine, the feel is fine, and the leather is shiny. The suture of the cortex is on the side turned over. The seam is straight and the arc is regular. The seams on both sides are right below the earmuff, symmetrical from left to right, giving a visual sense of orderliness. The sponge wrapped under the skin is very soft, and can quickly rebound when pressed to the limit, and is not shaped. There is no discomfort when wearing earphones on the head and rubbing the ears. If the material of this package is not genuine leather, the air permeability will be greatly reduced. Therefore, the earphone wearing comfort depends on this packaging material. The diameter of the earmuff can cover the entire auricle inside, leaving some room. The auricle and earphone have no sense of urgency. Enough space, very comfortable.

The ear bag lining is a thin cloth, which should be very thin for fear of affecting the sound quality.

Active noise reduction radio microphones are set on both sides of the shell, one on each side, symmetrically designed. Except for the audio interface, charging interface and switch, the whole headset is not symmetrically designed. All other parts are symmetrically designed. The overall appearance is very neat.

The heat dissipation vent of the headset is hidden in the seam of the shell. Two vents on each side are hollow holes in the metal cover. This design confirms the concept of "humanized breathable design" on the packaging box. However, this vent is not completely connected to the outside world. There should be some filter materials in the middle, otherwise the fully open vent will introduce noise and affect the noise elimination performance. Moreover, when wearing the earphone, the earphone and the ear will form a closed chamber. Gently press the outside of the earphone, and the eardrum will feel a sense of pressure, which proves that the formed chamber is nearly closed, and only pressing the shell can produce air pressure. This also confirms that the package of the headset is good. In addition to the active noise reduction function, it creates a quiet and closed music environment, and this vent ensures the release of heat without sweating and discomfort due to wearing headphones for a long time.

Rotate both sides of the earphone to be perpendicular to the head beam, and quickly connect the front end to listen COOLHEAR V1 Show your listening sense.

First, I listened to the first ear with the player I used to listen to. First, I tried a classic vocal song, "The Forgotten Time" by Cai Qin. The quiet active noise reduction function creates a very quiet background atmosphere, which also makes the vocal details more concrete. The rich vocal field is intoxicating, especially the quiet, melancholy and soothing feeling at the beginning of this song. The headphone performance is amazing, which makes the author really feel the characteristics of the "audio-visual field".

After listening to another audition divine song, "Hotel California" by the eagle, various musical instruments appeared one after another, and the on-site accompaniment was clear, V1 All the performances are worthy of recognition.

I used to use headphones to dictate rock and roll or bass, so I listened to some rock and roll and electronic dance music, and bass performance OK , without the boom of magic sound earphones. The bass is adequate, but the strength is moderate. After listening to these songs, generally speaking COOLHEAR V1 Sound performance is excellent, and all types of music are competent. These songs are APE The original songs in the format have not been tuned and beautified, so the performance of the earphones is also very real. But this earphone is the main 3D Holographic sound effect is not reflected. original COOLHEAR Have their own exclusive APP be called Coolhear 3D . Downloaded with mobile phone APP 。

COOLHEAR V1 The black background created can really give people a pure listening environment. They can enjoy music quietly on the plane or on the car. However, active noise reduction earphones are not recommended to be worn when walking, running or riding, because noise reduction will counteract external sounds. It is a great safety hazard that pedestrians and cyclists cannot hear external sounds. Therefore, avoid using it in this case. 3D Holographic sound image field is a fresh and highly audible idea.
