Sennheiser CX 300S (508594) in-canal headphones are a wired model with a built-in microphone and remote control, combining high sound quality with comfortable everyday use. Dynamic drivers, a wide frequency response of 17–21 000 Hz, and effective noise isolation make them an ideal choice for music, calls, and mobile entertainment.
The CX 300S model was designed for users who expect clear, dynamic sound in a compact form. Closed in-ear design effectively suppresses outside sounds, allowing you to focus fully on your favorite tracks, podcasts, or phone calls. The low 18 Ohm impedance ensures trouble-free operation with both smartphones and other audio devices.
The installed dynamic drivers with neodymium magnets guarantee deep bass, clear mids, and clean highs. A sound pressure level of 118 dB delivers powerful, distinct sound without losing detail. The wired design eliminates the need for charging, so the headphones are always ready to use.
Built-in microphone and an in-line remote control allow you to conveniently answer calls and control music playback without reaching for your phone. Cable with a length of 1,2 m provides freedom of movement during everyday activities, at work, or while traveling. The set includes silicone ear tips in four sizes (XS, S, M, L), allowing the headphones to be perfectly fitted to the ear and improving wearing comfort.
