HCT 3.5

T+A also offers cables with various plugs for the Solitaire T headphones. One of them is the 3.5 mm jack plug, which is currently the most widely used connector. However, jack plugs are not built symmetrically; the grounds of the left and right channels are connected. All contacts are hard gold-plated and made of high-purity brass. The HCT 3.5 headphone cable is available in 1.4 m length.
