This is a custom-made, high-grade cable for headphones, representing Haru Audio. I used it with Meze Audio's 109 Pro. Compatible with models that fit the NOBUNAGA Labs Advance Kirifuri. Cable length: 1.8m Headphone side: Bispa slim plug (3.5mm 2-pole straight plug) Device side: 4.4 plug with CINQBES/completely non-magnetic FA gold plating Two different thicknesses of wire, totaling 12 strands, and two types of solder are used. It brings out sufficient resolution, speed, spaciousness, sense of positioning, and reverberation as much as possible. From low to high frequencies, it reproduces all sounds with a sharp and clear outline.
