The HA-NCX78 in-ear headphones from JVC provide high-quality sound and a multi-noise reduction system, allowing you to enjoy your music without the distractions of the outside world. The noise reduction system reduces ambient noise by up to 88%, and also reduces wind noise, cable friction noise, and electrical noise. Neodymium drivers provide a wide, clear frequency response.
The earpieces come with memory foam eartips and 3 sizes of soft silicon eartips, allowing you to find the best fit for comfort and noise isolation. The cable's earloop design provides extra stability by directing cables around the ears. The cable provides plenty of slack, and has a gold-plated 3.5mm mini plug to provide compatibility with a wide variety of electronic devices. A dual-prong airplane plug is included for connecting to in-flight entertainment systems. The headphones can operate for up to 50 hours on a single AAA battery, and a handy carrying pouch is included.
