Upgrading your turntable's sound or replacing old, brittle wires? These are high-quality headshell leads. They connect your cartridge to the tonearm's headshell. They feature oxygen-free copper wires for clean signal transmission and gold-plated connectors at both ends for excellent conductivity and corrosion resistance. Each wire is color-coded and individually shielded for minimal crosstalk. They're about 40mm (1.75 inches) long and fit standard cartridges with pins 1.20-1.30mm in diameter. Specifically listed as compatible with a bunch of classic Pioneer turntables like the PL550, PL12D, PL-71, etc., but they'll work with many other standard mount tonearms too. A simple, affordable upgrade that can make a noticeable difference in clarity and channel separation. A must for any vinyl enthusiast tinkering with their setup.
