The Samsung EO-IC100 in-ear earphones in black offer a compact, lightweight in-ear design made of durable plastic, designed for comfortable, discreet everyday use. They feature a main USB-C connection compatible with many current smartphones, tablets and laptops, and also include 3.5 mm jack and USB options depending on the variant, making them easy to use with different devices. Their binaural configuration enhances stereo sound and helps reduce external noise, while the 32 Ω (ohm) impedance delivers a balanced sound suitable for calls and music.

They include a built-in microphone for clear conversations and hands-free control, plus in-line physical buttons to adjust volume, answer calls or pause playback without touching the device. The in-ear fit and approximate dimensions of 8.2 x 1.2 x 5.4 cm make them easy to carry and store, ideal for adults looking for a simple, functional accessory. Some models add Bluetooth and wireless connectivity, combining wired and cable-free options for greater versatility in different situations. The Samsung EO-IC100 are practical, versatile earphones that meet basic sound and communication needs on devices compatible with USB-C and standard connections.
