This allows frequency response personalization enhancing the listening experience. | Detachable CableThe IE 80 S features a rugged, detachable cable using the well-known Sennheiser proprietary 2-pin connector. This allows for easy replacement and optional cables to be used including the Sennheiser smart remote cable (a one-button, in-line microphone cable which turns the IE 80 S into a headset). | Personalized FitEar canal fit is crucial for earphone performance. The IE 80 S comes with a selection of ear tips, including a complete set of Comply memory foam tips (S/M/L sizes) to insure proper fit. This improves both sound quality and wearing comfort. |
