This 3-meter (9.9 ft) cable features a sturdy 4 mm diameter (3 mm after bifurcation) and a braided, tangle-free exterior, built around an OFC core for a clean, dependable signal path. The 3.5 mm male connector pairs with the 6.35 mm adapter, enabling compatibility with a wide range of amps, dacs, and desktop setups. Note: headphones are not included in the package.
