The MX 271 earbuds from Sennheiser provide high-quality audio in a lightweight and ergonomic design created to fit the needs of the modern active woman. Ideal as an upgrade to the earbuds that come bundled with most music players, the earbuds feature dynamic drivers that produce rich audio with a wide frequency response. A cable slider helps to manage tangles, while the 3.5mm plug provides compatibility with MP3 players, CD players, computers, and more.
