Headphones • Introduction

We have witnessed the rise of domestic mobile phones and the prosperity of domestic UAVs, but we have not seen the prosperity of domestic earphones. The images of Beats, Sennheiser, AKG and other earphones are constantly reverberating in my mind, and I want to ask: Where is the way for domestic earphones?

Maybe domestic earphones are rising, but they are not strong enough for non earphone enthusiasts like me. After contacting this domestic Coolhear earphone, I know that our earphones can still do this, and the effect is not bad.

Packaging • Accessories

As shown in the figure, the package of Coolhear V1 is simple and intuitive. The pure black compression cardboard box is printed with its half body rendering, while I received the dark night version V1, which is particularly consistent with the black packaging. Even the packaging box is also made into an artwork.

The packaging box is a folding design. After several times of turning, it will be found that its internal design and external design are also in a pure black style. Sponge is added to alleviate the violent fall during transportation. Packaging is like pure music, giving people a "beauty of jewelry" with pure black.

Accessories continue this sense of integration. Black earphone cable, black data cable, black small cloth bag, accessories also need to play the black key. In addition, a leather portable headset bag was presented, which is reasonable in design and specification.

Appearance • Style

When it comes to headphones, I always think that trendy people on the street must have something big and dark. In fact, today's international first-line earphone manufacturers have long been engaged in simple, fashionable, compact and flexible design. It is obvious that Coolhear V1 has kept up with the pace. It is equipped with small aluminum alloy ear shells, thick ear pads, and moderate head beam radian. It is most suitable for people with small or moderate stature, but it is a bit strange for a stout fat person to wear it.

Coolhear V1 is fashionable but not publicized, so after I get it, I will wear it on the street and when waiting in the coffee shop. Even after listening to the whole song Love Song King on the bus, no one will stare at me "surprised". Instead, I think this black version is too low-key and is inferior to the white version.

To be honest, although the appearance design of Coolhear V1 has reached the level of thousand yuan earphones, I think it is too common for the earphone industry to have such a "fashionable feel", which is not a characteristic selling point of V1, but only shows that it has the proper appearance.

Wear • Feel

Quote: The feeling of wearing is very intuitive. If you speak too well, you will be boastful. If you speak poorly, you will be confused. Therefore, it is reasonable to judge whether the official product introduction ("using the air convection pressure difference in the earmuff, not hot, not dizzy, not pinching the ear") is true by data and scene experience.

First, it is true that there is no ear clipping. From the picture alone, we can see that the head beam of Coolhear V1 has a small radian, which makes it feel natural to wear it, does not cause ear pain, and is easy to wear and take off. Unlike Beats, Bose and other earphones, which have large head beam radians, they use the method of "holding the ear" to solve the problem of easy falling off, which causes ear pain after wearing for a long time. In contrast, Coolhear earphones pay more attention to comfort.

Moreover, as long as the weight of the thousand yuan earphone does not reach 300g, it will not make people's head have a clear sense of weight. Official data show that the weight of Coolhear V1 is 264g, obviously V1 has a light body.

The moment she took off the earphone, it slipped down her hair, and the texture of the head beam was really smooth. Wide head beam+slippery texture+light weight: does that mean it will slip easily? That's not true, because the earplug has a deep concave design inside, so as long as it is worn to the upper part of the head, it will not be easy to loosen, but it is difficult to say about strenuous exercise.

People in Guangdong have an average daytime temperature of more than 20 ℃. She wore Coolhear V1 and I filmed for nearly two hours. When she took it off, her ears were not "dull red". What's important is that she did not complain: it was so hot to wear it! The earplug design of air convection has a good heat removal effect, and the feeling of "muggy" is not strong when wearing it.

I wonder if the "dizzy" in the earphone industry is like carsickness. It took more than 100 hours to use the machine before the deadline, and there was no feeling of "carsickness" during the whole process, but I listened and fell asleep

Sound quality • feeling

Coolhear V1 has an active noise reduction mute system (ANC patent). When I walked in the street and played a piece of pure music, "Tianlalu" felt that the world was quiet, and all I could hear were two sounds: one was music, the other was horn sound. The horn sound is because I didn't see the car when I was walking with my mobile phone. Secondly, the noise reduction technology is mainly to isolate the middle and low frequency sound, and still retain the high frequency sound of the horn.

When the bus is waiting for the traffic lights, have you ever heard a "Zizi" engine sound when sitting in it, or a "current sound" can always be heard by newly bought earphones. This is the low-frequency noise and earphone bottom noise. Experience that even if the volume of the Coolhear earphone is less than 1/3 of that, the annoying engine noise can be cut off, and the bottom noise is very clean.

Indeed, the most striking thing about Coolhear V1 is its "extremely quiet" noise reduction effect. As long as you wear it, you can listen to music with peace of mind, free from other noises. In official words, it is "experience peace and listen to my heart".

Next, enter the audio quality experience. In terms of equipment, I chose the music mobile phone vivo Xplay5, and the choice of music is also my favorite three songs, namely Feist's 1234, Beyond's Metal Madman, and 3D version of Canon Dream, which just represents the three styles of slow rhythm human voice fast beat rock 3D surround.

Feist 《1234》

Old fans should be familiar with this song. It used to be an advertising song for iPod. The rhythm is light and the voice is pure, which can relieve stress and relax people. It is suitable for testing the vocal processing effect of Coolhear V1. The first song I heard just after I got Coolhear V1 was 1234. When I opened it, I felt its voice was thick and its voice was dim, just like there was no mature "mango is very astringent".

After five days of warming up, this earphone was "ripened". The stiff voice became fresh and pleasant, and the slow beat was very soft. Especially the "One two three four" just opened was very natural and real, and the voice became a little "sweet". This headset performs well on magnetic mid-range vocals. This rhythmic, mid-range vocal music is no inferior to Coolhear V1.

Beyond Metal Madman

In 1991, Huang Jiaju went on stage to sing Metal Madman shirtless. Do you still remember that scene? The "Metal Madman" I chose to listen to came from the life contact concert. The rhythm of this song is very fast. It is a heavy metal music that Jiaju fully released.

The prelude of this song originates from Masnai's "Meditation". Huang Jiaju plays this violin song with an electric guitar, which becomes quite metallic. Listening to the prelude of Metal Madman with Coolhear V1 is a bit ethereal, and the gentle style is a bit "unable to grasp" the metal craze of electric guitar. On the contrary, using Coolhear V1 to listen to the original version of Meditation on Violin will make the original soft and elegant violin sound more relaxed and highlight the quiet scene. Then we continued to play Metal Madman. When Huang Jiaju sang fast, V1 kept a clear voice, but lost a sense of pleasure in the scene.

3D surround version of Canon Dream

After listening to 3D music, you will feel that the songs are shuttling around in your ears. Coolhear earphones mainly focus on 3D holographic sound field, and also have their own 3D music APP. I selected this familiar "Canon Dream" there.

Coolhear 3D APP can make songs feel "moving". There is a small circle in the APP. As I drag with my fingers, the music will also change its sound track and distance. It is a vivid metaphor: it operates like playing a disc, and sounds like being in the scene. In addition to finger control, music will also change with gravity sensing. Therefore, this technology is mainly for VR development. When I bring my own hand made VR, it's really cool to "shake my head" and listen to music!

Returning to the 3D music experience, Canon's lively melody is fully preserved in Coolhear V1, especially the clear and pleasant singing of birds. The biggest music feature of V1 is that I can grasp every detail of these gentle songs. I deeply fell in love with this song. After listening to it five times before going to bed, I didn't want to sleep because of the real enjoyment surrounding it

The author is not a professional music enthusiast and does not know much about the descriptive nouns of sound quality, so it is necessary to quote the general comment of professional players on the sound quality of Coolhear V1 when summarizing the sound quality: "The gentle and delicate style, soft and smooth texture, complete details restoration, high sound density, but not very fast, suitable for listening to moderate to slow rhythm, relatively soothing music."

Coolhear V1 is like a cup of coffee. It is sweet when playing voice, and mellow when isolating noise. This experience needs to be tasted slowly.

At the end of the article, a brief talk

Figuratively speaking, Coolhear V1 is an elegant headset. Its shape is fashionable and unobtrusive, the head beam is loose and not locked, the sound effect is slow and not exciting, and the noise is quiet and not low. Obviously, people with leisure will naturally like this slow and quiet melody.

Because the head beam has small radian, light weight and gentle sound effect, Coolhear V1 is not suitable for outdoor strenuous sports, which is its use limitation. To be successful, our earphones must have a technical advantage in addition to cost performance and excellent sound quality. Maybe noise reduction is a good choice.

Maybe many people want to know how the Coolhear V1, as an active noise reduction headset, consumes power? In fact, most of today's active noise reduction earphones can last for a long time without realizing that "power is lost so quickly?" From my own actual experience, the V1 is only charged once after more than 100 hours of use, and the endurance performance is reasonable. I prefer life to tranquility. Indeed, the noise reduction effect of Coolhear V1 is very good.
