Sennheiser CX 300S In-ear Headphones, Black

The Sennheiser CX 300S is a wired set of in-ear headphones built around dynamic drivers that provide a frequency response of 17 Hz to 21,000 Hz. The acoustic system is closed, which contributes to bass reproduction and sound isolation. With a standard impedance of 18 ohms and sensitivity of 118 dB, these earphones are engineered to function effectively with most mobile devices and computers that have a 3.5 mm audio output. The 1.2-meter cable is fitted with an angled connector to reduce strain at the connection point.

The ergonomic, canal-style design offers passive noise isolation by forming a seal in the ear to reduce ambient sound. For a proper fit, the earphones come with four sizes of silicone ear tips (XS, S, M, L). An in-line remote is integrated into the cable, featuring a single button for managing music playback and answering calls. This remote also houses an omnidirectional microphone for voice capture during calls. The unit weighs 12 grams and includes a soft pouch for storage.
