The HCSE 4.4T+A headphone cable series is designed to enhance audio quality by providing three different cable options equipped with various plugs, one of which features a 4.4 mm Pentaconn connector. This particular connector is notable for its symmetrical wiring, which allows for the complete separation of left and right audio channels. This separation prevents ground connection interference, which is a common issue in many non-separated systems, such as those using a standard jack plug. This innovation results in a significant reduction in adverse effects on sound quality.

Research indicates that the Pentaconn connector not only facilitates superior audio channel separation but also provides the best contact quality when compared to the XLR and jack plug alternatives. To further ensure optimal performance, all the connectors in the HCSE 4.4 series are hard gold-plated and made free of ferromagnetic materials, which could potentially affect sound integrity.

The HCSE 4.4 headphone cable is available in two lengths, 3 meters and 5 meters, catering to different user needs and setups. Overall, the design and construction of these cables focus on delivering high-quality audio experiences by minimizing interference and maximizing connectivity efficiency.
