The Sony MDR-E827G are earbud style headphones from Sony's Sports and Active Style line. The headphones feature Sony Acoustic Twin Turbo Circuitry for powerful bass and sound efficiency and Neodymium magnets which provide more power and clearer sound than commonly used magnets. They are designed with Sony's Fontopia in-the-ear design with a thinner housing and slim duct for a secure, comfortable fit. The MDR-E827G are water resistant and also include a directional bass cap to enhance bass sound. They have a 3.3 ft cord with a nickel-plated L-shaped stereo plug and come with a compact wind-up case for easy storage and portability. The MDR-E827G stand out from the other headphones in Sony's Sports and Active Style series since they feature the Fontopia in-the-ear design and wind-up case which none of the other models have.
