true wireless earphones or true wireless noise-cancelling earphones can be said to be the most popular products on the market today. The rise of wearable products such as true wireless earphones has become one of the indispensable digital products in the daily life and work of contemporary young consumer groups. However, there are a wide variety of such products on the market now, but the so-called "smart wearable" devices only stay at the device level, and seem to forget that there is still a demand for wear. Today, when the appearance of true wireless earphones on the market is extremely homogeneous, ROtt KRON polycrystalline zirconium earrings were born. This earphone inherits the Nordic design style that advocates freedom, simplicity and humanistic spirit, combining technology with fashion. The perfect combination basically redefines the fashion trend of true wireless earphones.
I think it is necessary to talk about the ROtt KRON earphone brand before introducing this earphone, which is a pioneering earphone brand under the Swedish Lövepac. Founded in southern Sweden in 1968, Lövepac was fully incorporated into the Nolato Group in 1986. Lövepac only serves top global customers, including the former Nokia and Blackberry, and now Google, Sony and Dyson. This shows that the strength of this company cannot be underestimated.
Unparalleled and unique sound
ROtt KRON polycrystalline zirconium earrings are one of the few or only true wireless earphones on the market that use polycrystalline zirconium sapphire sound cavity. The earphone is a dynamic earphone. The earphone is equipped with a 10mm custom graphene dynamic unit, coupled with a polycrystalline zirconium sapphire sound cavity, which lays the foundation for excellent sound quality performance. And this headset also supports SBC, AAC, aptX Bluetooth decoding formats. The biggest highlight of ROtt KRON polycrystalline zirconium earphones is the gemstone sound field created by polycrystalline zirconium gemstone technology. Different sound cavity materials will lead to different degrees of sound wave attenuation, especially for medium and high frequencies. The polycrystalline zirconium material density of ROtt KRON Lekuang polycrystalline zirconium earphones is as high as >6g/cm3. After sintering at a high temperature of 1500 degrees, the polycrystalline zirconium forms nano-level dense grain boundaries connected, diamond-level dense crystals, sound bottom clean,The sound loss is low, the distortion is small, the sound is clear and thorough, and the expression is delicate and subtle. In theory, it will obtain a more excellent high-frequency performance. In addition, the ROTT KRON earphones also use SurfaceTech surface patent technology. The inner wall of the gemstone sound cavity is innovatively treated to form unique surface physical characteristics, which greatly reduces the reflection of sound waves and reduces the interaction of standing waves. In addition, the polycrystalline zirconium sapphire cavity of this headset is composed of dense polycrystalline polycrystalline zirconium sapphire sound cavity with higher strength and better stability, which can isolate the external noise of the sound cavity to the greatest extent and obtain a better hearing experience.
When you first listen to this earphone, you will feel that the sound style is somewhat unique. This may be the first time I have heard this kind of sound style. It can be seen that the polycrystalline zirconium gemstone sound cavity is not simple. But when you calm down and feel it carefully, you will find that all this is just right. The volume and density of the low frequency of the earphone will indeed be slightly more. Although the low frequency is thicker, it will not be muddy, and it still sounds very good. Refreshing, when I use this earphone to listen to some pop or jazz music on the road every day after get off work, I feel very relaxed; the sound field of this earphone is also excellent enough in the mid-high frequency, and the characterization of the sound details is very good In place, vocals and instruments can also have a good degree of separation. Overall, ROtt KRON polycrystalline zirconium earphones have a solid and surging sound field width and depth in low frequencies. It's clear, and it sounds contagious. I think this may be the charm of polycrystalline zirconium sapphire sound cavity.
Unboxing & getting started: One word "tide"
The biggest highlight of the sound quality After talking about the sound quality, let's take a look at one of the highlights of this model: the design. When I got the ROtt KRON polycrystalline zirconium earphones, I already felt the difference of this earphone. It is like a fashion item that has been popular in the trend circle, and it is different from the current market. True wireless earphones are so unique, and the design of earphones or charging boxes is always showing a fashionable atmosphere. There are currently four main colors of ROtt KRON polycrystalline zirconium earrings.They are: Nordic Woods/Northern Forest, West Gentle/Western Tenderness, Spring Swing/Yang Yangchu Spring and Neo Fantasy/Neon Symphony.
When I first saw this earphone, it seemed that the design of the charging case was very simple, but after careful observation I discovered the mystery. The charging box of the ROtt KRON polycrystalline zirconium earphones adopts a circular design with a flat bottom. The charging box uses a large area of black frosted plastic. Compared with the glossy piano paint, the frosted plastic is more durable. Dirt-resistant and scratch-resistant, it is also very convenient for daily use and care. The Neo Fantasy / Neon Fantasy color scheme in my hand looks very sci-fi. The decoration on the lower part of the earphone charging box is colored with NCVM technology. The treated surface has a dazzling effect. Reflective, I love the way this color is handled.
ROtt KRON headphones are from northern Sweden, and the overall design inspiration of the headphones also comes from its hometown. Headphone designers took the horned hats of the Scandinavian Vikings 1,300 years ago as inspiration. Opening the earphone charging box The main body of the earphone is inserted upside down in the charging box, and the protruding earphone ear handles are like two pointed horns, so when the earphone charging box is opened, the charging box and the ear handle are really like a reduced version. horn hat. This is the first time I have seen such a design. I think this very unique earphone design should better cater to the tastes of young people in the current Z era.
ROtt KRON The cavity material of the polycrystalline zirconium earphones is definitely worth mentioning. Japan TOSOH [Tosoh] is the inventor of yttrium-stabilized zirconia, the world's leading supplier of nanocomposite zirconia, and a material supplier for top luxury brands, such as Rolex's green water ghost's ceramic ring The white materials of the Chanel J12 series use the raw materials provided by Tosoh. The ROtt KRON earphones use the original polycrystalline zirconium powder provided by the luxury homologous supplier Tosoh, and use the ceramic injection molding technology (CIM) to create the polycrystalline zirconium gem (ceramic) sound cavity of this earphone.And the gemstone sound cavity of this headset is available in a variety of colors. The sound cavity of the ROtt KRON polycrystalline zirconium earrings is very beautiful. The sound cavity of this earphone has a gem-like luster and a jade-like warm hand. In addition, the sound cavity material is also very friendly. Skin, wearing this headset is very comfortable, and the stability is also very good.
This earphone also comes with an earring and earring, which is made of all-metal material. The earring is designed with a place to hang the earphone and a brand logo made of metal. The biggest function of the earrings is to further add the accessories of the earphones in the daily use of the earphones. When the earphones are not in use, the earphones can be hung on the chest through the earrings to make the daily use more convenient. In addition, it prevents the earphones from being lost when not in use. In any case, the biggest role of this earring is to further enhance the overall fashion sense of the earphone during use. When the daily trend is out on the street, the ROtt KRON polycrystalline zirconium earphone is used as a daily wear. It is a small accessory that can be used for two purposes, and it is also a cool accessory. In addition, both this earphone and earrings and earrings have a variety of colors to choose from. When I wear them everyday, I will choose earphones or earrings and earrings of different colors to match what I wear that day. Such a match It will appear more unified and more able to show my own unique taste.
In fact, you can also add your favorite elements to the earrings and earrings according to your mood. I like to buy some small decorations online, so that you can add your own fashion to the earrings and earrings elements, so that the original design is no longer monotonous, but also can show its own unique taste and personality. In my opinion, this seems to be an open jewelry ecology, where richness and frugality are created by people, according to their own personality, to show everyone their different attitudes towards life.
In our inherent impression, brands from Sweden have always presented us with a minimalist and cold design style, such as IKEA and Volvo, which are very typical design styles from northern Europe. ROtt KRON headphones have changed my inherent impression of the Swedish brand design style.Although this brand also comes from Northern Europe, it has a very bold and trendy design. The designer of ROtt KRON polycrystalline zirconium earrings is unwilling to follow the mainstream design of the current true wireless earphone market, but wants to show the fashionable soul of his own brand, and wants to satisfy the basic functions of the earphones and let consumers You can also use this earphone as a fashion accessory. I want to create a strong sense of fashion trend with fashionable design, bold color matching, and individual shape to win the favor of contemporary young people. Overall, this headset breaks the boring framework of traditional electronic products and brings endless possibilities for products.
In-depth experience: two words "excellent"

This headset uses Qualcomm QCC 3040 chip and supports Bluetooth 5.2. In addition, the headset is also equipped with Qualcomm call noise reduction technology. The design of noise reduction microphone and noise reduction algorithm can reduce the interference of noise on call quality to the greatest extent. Users get a pure and clear call experience. In order to experience the call noise reduction effect of this headset, I specially brought this headset to the outdoor experience. When I stood on the second ring road with heavy traffic flow, I used ROtt KRON polycrystalline zirconium earphones to communicate with others. When making a call, the other party reported that my voice would not be masked by the surrounding noisy ambient noise or wind, and the call effect was very good.
In terms of battery life, the ROtt KRON polycrystalline zirconium earrings have a single listening time of 6 hours. If used with the charging box, the comprehensive battery life can reach 30 hours, which is satisfactory. In addition, this headset also supports IPX7 waterproof level, which is rare in the industry. Under this level of waterproofing, the performance of the headset will not be affected after immersion in the deepest one meter of water for 30 minutes, which means rain and sweat during exercise. Can't damage the earphones.
at the end
Swedish brand I know well,They all seem to be very obsessed with one thing and do what they are obsessed with at all costs. Like Volvo and Saab, they have always been very obsessed with safety. This seems to be the belief engraved in their DNA, and they must do this well. After the experience in the past few days, I also felt the obsession of the brand ROtt KRON earphones. They are obsessed with creating the most fashionable products at the moment, which can provide more choices for contemporary young people. As the first product of the brand, the ROtt KRON polycrystalline zirconium earphones have well pulled earphones into the trendy jewelry circle, perfectly integrating art and technology.
