The acs eclipse 500 is designed for musicians engineers and audio lovers who need accurate sound lasting comfort and long term reliability. It uses a powerful 8mm dynamic driver for rich controlled bass along with dual balanced armature drivers for clean midrange and a dedicated super tweeter for high end clarity. These drivers are combined through a passive 3 way crossover to maintain separation allowing each frequency range to shine without overcrowding the soundstage. Acs has integrated its 17db ambient filter to reduce the pressure build up often felt with in ear monitors. This helps air pass naturally in and out of the ear canal creating a more open and relaxed sound while still offering effective isolation. The result is a more comfortable and immersive experience for longer listening sessions. A choice of cnc machined nozzles in different lengths lets you tailor the fit and sound to your preference and the included foam tips in multiple sizes add further comfort and seal options. The aluminium housings are tough but lightweight and feature interchangeable faceplates for added style and durability. The cable is built from high purity oxygen free copper silver plated for low capacitance and designed to minimise signal loss across its full length.
