That grille is a precise two-layer laser-cut mesh structure.\u003c\/p\u003e\n\u003cp\u003eMagnesium alloy is used for the housing base plate and hangers, natural sheepskin for the headband and head pads, and silk-protein synthetic leather for the ear pads. The result is a wide, natural soundstage with high resolution and clear instrument separation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKumiko-Inspired Aluminum Lattice\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe open side of each housing is a matte anodized aluminum panel cut with a geometric lattice motif taken from kumiko, the centuries-old Japanese joinery craft that fits wood together without nails. The pattern is realised as a precise two-layer laser-cut mesh, so it functions acoustically as an open grille while carrying the visual reference.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFlagship 50 mm BioDyna Driver\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe TH818 uses the same 50 mm neodymium BioDyna diaphragm driver as the closed-back TH810, reproducing 12.5 Hz to 45 kHz. In the open-back enclosure it trades the TH810's sealed low-end weight for a wider, more natural soundstage with clearer separation between instruments.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMagnesium Alloy Construction\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe housing base plate and hangers are magnesium alloy rather than aluminum, cutting roughly 20 percent of the mass of the equivalent parts and suppressing unwanted vibration.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSheepskin and Silk Protein Comfort\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNatural sheepskin is used for the head pad and headband, while the ear pads use a silk-protein-based synthetic leather rated at roughly three times the durability of conventional synthetic leather.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetachable 7N OFC Y-Cable\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe supplied 2 m detachable Y-cable uses 7N grade (99.99999 percent) high-purity OFC conductors, with 3.5 mm 2-pole mini plugs at the earcups and a 6.3 mm gold-plated stereo plug at the amplifier.\u003c\/p\u003e\n\u003cp\u003eB-stock may have minor cosmetic scratches or dents and furthermore B-Stock is not covered by full manufacturer warranty.
