For clear, full sound the JVC HA-F240 features a large 11mm neodymium driver unit that offers high power handling and sensitivity. To further enhance the listening experience, friction noise has been greatly reduced through the use of a 1.0 meter friction noise reduction cord, equipped with an iPhone-compatible plug. The silicon rubber air cushion sets a standard for comfort in the ear bud category. The soft-touch cushion changes shape to conform to the contours of the wearer's ear, ensuring that the ear buds fit securely and comfortably. The HA-F240 meets the demands of the style-conscious music listener, all the way down to the matching color cord.
