JVC Carbon Nanotubes In Ear Headphones, Blue

The JVC HA-FX40 inner ear headphones (Blue) feature carbon nanotubes diaphragms that deliver clean, crisp sound. Other key features include dual-layer housings for enhanced sound isolation, a rubber fitting stabilizer for a secure and comfortable fit and a selection of earpieces to suit a wide range of ear shapes. Carbon nanotubes diaphragms represent a breakthrough in headphone technology as the material provides a balance of strength and flexibility that cannot be matched by diaphragms made from metals or plastics. When paired the large 8.5mm driver units in the HA-FX40, the result is exceptionally crisp, detailed full-range sound, particularly in the mid-high frequency range.

Superior external sound isolation and a secure fit are ensured by dual-layer aluminum-plated earphone housings and a new rubber fitting stabilizer that fits the contour of the ear. To further enhance the fit, each headphone comes with three pairs of silicone earpieces in small, medium and large, plus a set of memory foam earpieces. Sound quality is maintained from source to ear through the use of a high-quality gold-plated 3.5mm plug compatible with all Apple devices and a 3.94-foot (1.2 meters) pure oxygen-free copper (OFC) cord. A cord clip is provided to minimize cord friction noise.
