Many headphone cables do not come with a microphone; HEM Cable provides a pure and clear sound quality while facilitates users with a convenient call function and manipulability. HEM Cable, the mobile headphone cable exclusive for HEM series, is developed for NuForce HEM IEM. The cables use silver plated copper core with low impedance and independent grounding wire to create clear and penetrating sounds. The robust core is protected by Dupont Kevlar 200D fabric cover. The microphone, adopting Knowles™’s SiSonic™ MEMS technology for communication, is compatible with smartphones using iOS & Android systems; users can answer the phone, adjust the volume and activate the voice assistant.
