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.

She is the owner of the garden of Asgard and responsible for the rejuvenation of the apples. She is the daughter of Ivald, the dark dwarf with the most powerful magic in the underground city. She is beautiful, and her father has cast a spell on her that will keep her young forever. Idun is unanimously loved by the gods of the Aesir, and her beauty is also one of the most beautiful among the Aesir gods. The goddess of fate, Norn, gave Idun the youth apples from the tree of life to keep. The youth apple is the treasure of the Aesir Protoss. It can keep the gods young. It is also called "Idun's Blessing," but it must be picked by Idun herself and placed in an ash chest before being given to the gods. Idun devoted herself to guarding the Apple of Youth, and the gods could rest easy.SpecificationsImpedance 32 ohmsSensitivity 112+/-2dBRated power 3mWDynamic distortion <3%(1kHz,100dB SPL)Cable length 1.2m Driver 1DD+2BAConnector 0.78mm 2pinEar tips: k-07 Balanced Tips (balanced sound and stereo); K-285-02 Vocal Tips (release high frequencies, pleasant vocals); Foam Tips (rich vocals and deeper bass)Material: OFC+OFC with silver coatingbraiding type: 8 cores 3-dimensional braideddiameter: 1,0mm per corestrands: 25 strands of 0.05mm OFC with silver plating + 25 strands of 0.06mm OFCCable sheath material: PVCInterface: 0,78mm 2PinConnector: detachable 4,4mm symmetrical / 3,5mmConnector material: copper with 24 carat gold platingCable length: 122cm+/-2cmAdapter: 3.5mm to 6.35mm
