Wired earphones Jack 3,5 mm Sennheiser CX 300S black

The Sennheiser CX 300S in-ear headphones (S508594) with a built-in microphone and smart remote are a wired model that delivers dynamic, detailed sound and effective isolation from ambient noise. With a frequency response of 17-20,000 Hz, a high dynamic range of 118 dB, and an ergonomic design, they are perfect for listening to music and taking calls.

The closed, in-ear design combined with flexible earbuds effectively reduces external noise. Passive noise isolation allows you to focus on your music even in noisy environments – on public transport, in the office, or while walking. The ergonomic shape ensures a stable and comfortable fit.

The model is equipped with dynamic drivers with Sennheiser technology, which offer deep bass, a clear midrange, and clear highs. The 18Ω impedance makes the headphones compatible with smartphones and other portable devices, ensuring adequate power and sound clarity.

The built-in microphone and in-line remote control allow you to conveniently answer calls without having to reach for your phone. The 1.2m cable is designed to reduce tangles and increase durability during everyday use. The set includes interchangeable ear adapters in four sizes (XS, S, M, L) and a practical storage case.
