KBEAR KB02 bone conduction earphones. (Please refer to the images as I am not familiar with earphones) Used only for photography, so they are almost new. Everything in the images is included, and all the included pins are complete, but one of the ear tip bags is slightly torn. It's not very noticeable. I will ship promptly after receiving your order. Shipping will be via Yu-Packet Post. Other features: Bone conduction, Removable cable #KBEAR #BoneConductionEarphones #KB02 【10mm Beryllium Dynamic Driver】 The KB02 uses the same 10mm beryllium diaphragm as the Kiwi Ears Cadenza. Beryllium diaphragms have always been the top choice material, providing powerful and stable sound. In addition, to reduce the interference of standing waves on the sound, the KB02 brings the dynamic driver closer to the nozzle, further improving the performance of the mid and high frequencies. At the same time, a bone conduction unit is added to supplement the low frequencies, making the sound more musical, the low frequencies more vivid, the soundstage wider, and providing a more balanced and beautiful sound. 【KBEAR's First Bone Conduction Unit HIFI Earphones】 The KB02 in-ear monitors have a bone conduction unit embedded in the cavity, which efficiently transmits vibration energy, significantly improving the sound quality. As a low-frequency and ultra-low-frequency compensation unit, it can enrich the bass, create a wider soundstage experience, and enrich the layers and details of the sound. 【3D Printed Resin Cavity】 The KB02 earphone cavity adopts advanced 3D printed resin technology and combines it with exquisite spray painting technology, achieving a high degree of customization and uniqueness in detail. This gives the cavity a rich texture and vivid colors, providing enjoyment both visually and tactilely. This design not only enhances the aesthetic appearance of the earphones but also adds artistic charm to the sound quality and wearing comfort. The patterns on the surface of the earphones are all unique, allowing you to enjoy an excellent sound quality experience while also enjoying the excitement of unboxing.
