We prepared 5 color variations for its HPC-26T cable. The length is 1.2m which is the best using with portable audio players.

The conductor is made of PCOCC-A pure copper which achieves great sound quality. The outer sheath is made of Pb free PVC and the insulation material is PFA which has excellent electrical property.

We use our original audio grade solder, SS-47 for the connection of plugs and cables of HPC-UE. Compared to general solders which usually contain 3N (99.9%) pure tin, SS-47 contains 4N (99.993%) pure tin achieved by excluding impurities to the maximum. Furthermore, 4.7% silver and 1.7% copper are contained for the purpose of improvement of electric conductivity and durability.
