The E4C earphones feature a High-Definition driver with Tune Port technology for an ultra-wide frequency soundstage with brilliant highs and extended bass. As the ideal companion to any portable or home audio source, the E4C incorporates the same precision components used by professional musicians to bring incredibly accurate sound with remarkable isolation. The E3G's in ear design works like an earplug to block background noise naturally. This enables you to listen comfortably at lower volumes, even in loud environments. And unlike bulky headphones utilizing active noise cancellation technology, no artifacts are introduced into your listening experience. Sound isolating earphones are also much smaller and don't require batteries. The soft, flexible sleeves in the Fit Kit gently contour the inside of the ear for a comfortable, secure fit so that the earphones don't fall out while you're exercising. The cable spool inside provides a convenient, tangle-free way to store your earphones. Sensitivity (at 1kHz) - 109 dB SPL/mW Impedance (at 1kHz) - 29 Ohm Cable Length - 1.42m (56 inches) Input Connector - 3.5 mm (1/8 inch) gold-plated stereo plug Unit Weight - 31 gram (1.1 ounces)   Show Less
