T+A offers a selection of three headphone cables with different plugs. One of them is equipped with a 4-pin XLR connector (manufactured by Neutrik). Its symmetrical wiring allows for a complete separation of the left and right channel. Severing the ground connection between both channels renders any adverse influences on sound quality which might arise in non-separated systems such as the standard jack plug all but impossible. All contacts are hard gold-plated and free of ferromagnetic materials. The HCSE XLR headphone cable is available in 3m and 5m lengths.
