Bi-METAL Structure Headphone

Bi-METAL Structure Headphones with red finish...The JVC HA-FX300 employs a range of sound-enhancing technologies, including an aluminum evaporation diaphragm, a new internal dual-metal structure and aluminum housing. The new aluminum evaporation diaphragm used in the HA-FX300 reproduces high-frequency detail more accurately than conventional cellulose or polymer-based diaphragm designs. To further enhance performance, the headphone features JVC's new Bi-METAL structure -- the drive unit is housed in a stainless steel base wrapped in a high-specific-gravity brass ring to eliminate vibration and energy loss, enhancing performance across the frequency range. Other innovations are aluminum housings, designed to reduce resonance, and the use of OFC (oxygen-free copper) to minimize transmission loss in the 1.0 meter friction noise reduction cord. The HA-FX300 also offers a plug that is compatible with Apple's iPhone. To ensure a snug, comfortable fit the headphones come with three different sized silicon rubber earpieces and a pair of memory foam earpieces for a customized fit, while at the same time delivering superior isolation from external sounds and minimizing sound leakage.
