Used for about six months. Operation confirmed. There is damage to the right housing. The sound output is completely fine. Thank you. Topology Diaphragm: A diaphragm with a special nanoparticle coating on the surface. The idea behind the new topology diaphragm was inspired by Dr. Fang Bian's paper, which stated, "Nanomaterials have different structures, and each material has its own unique properties." Therefore, by carefully controlling the surface structure of the diaphragm, different results can be obtained in acoustic performance to a degree that has not been achieved before. [50mm Dynamic Driver with Highest Sound Quality] High sensitivity using rare earth magnets by HIFIMAN, advanced voice coil, and topology diaphragm achieve detailed high-frequency response up to 30kHz. Form Follows Function: CNC-carved wood and aviation aluminum. The large internal space of the wooden earcups provides ample volume and "breathing space" for the powerful drivers. Cable: The HE-R10D package includes a detachable cable with a 3.5mm jack and a 6.35mm adapter.
