Kinera Idun Drive unit: 2 Balanced Armature+ 1Dynamic hybrid 3 drive unit Balanced and versatile tuning style with great sound quality and listening experience. We recommend it to those who don't have a particular music genre preference.The earphone utilizes a unique chamber structure and combines it with a DD-BA hybrid design to achieve smooth transitions from mid-low to mid-high tones. The high tones are wide and transparent with a spiritual quality, while the low tones are deep and powerful, bringing a surprising auditory experience. The earphone provides a strong sense of presence, satisfying the desire for high-quality sound experience. The earphone is manufactured using high-precision laser-curing 3D printers, which quickly and accurately shape the resin chamber based on refined model data. The earphone casing made with this process is not only more precise in acoustic performance but also fits the ear canal better than those made with general manufacturing processes. The IDUN earphone cable is made by mixing and weaving 4-core OFC and OFC coated with silver. Each core of the cable is composed of 25 finely woven, 0.06mm spiral strands, resulting in a multi-core, ultra-fine wire structure. The barrel-weaving method used in the production process makes the cable more flexible and comfortable to wear. The classic combination of OFC and OFC-coated with silver produces high-quality music while retaining the emotional qualities of copper wire. The earphone cable is equipped with deeply gold-plated brass plugs and pins, which effectively reduce contact distortion and eliminate oxidation of the plugs.
