Wire earphones Jack 3,5 mm Sennheiser CX 300S white

The Sennheiser CX 300S in-ear headphones (508594) are a wired model with a built-in microphone and remote that combines high sound quality with the convenience of everyday use. Dynamic drivers, a wide frequency response of 17-21,000 Hz, and effective noise isolation make them the perfect choice for music, calls, and mobile entertainment.

The CX 300S model was designed for users who expect clear, dynamic sound in a compact form. The closed, in-ear design effectively attenuates ambient noise, allowing you to fully focus on your favorite songs, podcasts, or phone calls. The low impedance of 18 Ohm ensures seamless compatibility with both smartphones and other audio devices.

The dynamic drivers with neodymium magnets guarantee deep bass, clear midrange, and clean highs. A sound pressure level of 118 dB translates into powerful, expressive sound without any loss of detail. The wired design eliminates the need for charging, so the headphones are always ready to go.

The built-in microphone and in-line remote allow you to conveniently answer calls and control music playback without reaching for your phone. The 1.2 m cable provides freedom of movement during everyday activities, at work, or while traveling. The set includes silicone earbuds in four sizes (XS, S, M, L), allowing you to perfectly fit the headphones to your ear and increase wearing comfort.
